INTRODUCTION TO THE NEW YORK MERCANTILE EXCHANGE
Significant, sometimes abrupt, changes in supply, demand, and pricing have touched
many of the world's commodity markets during the past 25 years, especially those for energy. International politics, war, changing economic patterns, and structural changes within the energy industry have created considerable uncertainty as to the future direction of market conditions. Uncertainty, in turn, leads to market volatility, and the need for an effective means to hedge the risk of adverse price exposure. The principal risk management instruments available to participants in the energy markets today are the versatile futures and options contracts listed on the New York Mercantile Exchange. The contracts are designed to meet the needs of the modern energy industry by encompassing the standards and practices of a broad cross-section of the trade. The Exchange is the world's largest physical commodity futures exchange. Trading is conducted through two divisions: the NYMEX Division offers futures and options contracts for light, sweet crude oil; heating oil; New York Harbor gasoline; natural gas; electricity; and platinum; futures for propane, palladium, sour crude oil, Gulf Coast unleaded gasoline; and and options contracts on the price differentials between heating oil and crude oil, and New York Harbor gasoline and crude oil, which are known as crack spread options. The COMEX Division lists futures and options on gold, silver, copper, aluminum, and the FTSE Eurotop 100 European stock index; and futures for the FTSE Eurotop 300 stock index. The NYMEX Division heating oil futures contract, the world's first successful energy futures contact, was introduced in 1978. The light, sweet crude oil contact, launched in 1983, is the most actively traded futures contract based on a physical commodity in the world. These contracts, and the others that make up the Exchange's energy complex have been adopted as pricing benchmarks in energy markets worldwide.
The Exchange's electronic trading system, NYMEX ACCESS, allows trading in energy futures and options, platinum futures and options, and other metals futures after the trading floor has closed for the day. The NYMEX ACCESS trading session for light, sweet crude oil; heating oil; New York Harbor unleaded gasoline; and the metals contracts begins at 4 P.M. and concludes at 8 A.M. the following morning, Mondays through Thursdays. A Sunday evening session commences at 7 P.M. When combined with the daily open outcry session, NYMEX ACCESS extends the trading day to approximately 22 hours.
Natural gas and propane are offered in abbreviated evening sessions. Electricity contracts trade exclusively on NYMEX ACCESS for approximately 23 hours a day. Terminals are in use in major cities in the United States and in London, Sydney, Hong Kong, and Singapore.
Efficient Markets Require Diverse Participants
To be efficient and effective risk management instruments, futures markets require a mix of commercial hedgers and private speculators. The New York Mercantile Exchange's energy markets have attracted private and institutional investors who seek to profit by assuming the risks that the underlying industries seek to avoid, in exchange for the possibility of rewards. These investors, in combination with hedgers, have brought a diversified balance of participants to the Exchange's markets.
How a Transaction Works
The execution of a transaction on the trading floor is a finely honed process that can be completed in seconds. The open outcry auction process on the floor assures that transactions are completed at the best bid or offer. The process starts when a customer calls a licensed commodities broker with an order to buy or sell futures or options contracts. The broker sends the order to his firm's representative on the trading floor via telephone or computer link. An order slip is immediately prepared, time stamped, and given to a floor broker who is an exchange member standing in the appropriate trading ring. All buy and sell transactions are executed by open outcry between floor brokers in the same trading ring. Buyers compete with each other by bidding prices up. Sellers compete with each other by offering prices down. The difference between the two is known as the bid-ask spread. The trade is executed when the highest bid and lowest offer meet. When this trade is executed, each broker must record each transaction on a card about the size of an index card which shows the commodity, quantity, delivery month, price, broker's badge name, and that of the buyer. The seller must toss the card into the center of the trading ring within one minute of the completion of a transaction. If the last line on the card is a "buy,"
the buyer also submits the card to the center of the ring; the card is retained by the Exchange as part of the audit trail process. The cards are time-stamped and rushed to the data entry room where operators key the data into the Exchange central computer. Meanwhile, ring reporters listen to the brokers for changes in prices and enter the changes via hand-held computers, immediately disseminating prices to the commercial price reporting services as they simultaneously appear on the trading floor wallboards. Confirmation of each completed trade is immediately made by the floor broker's clerk to the originating broker who then notifies his customer.
What are Futures?
Futures contracts are firm commitments to make or accept delivery of a specified quantity and quality of a commodity during a specific month in the future at a price agreed upon at the time the commitment is made. The buyer, known as the long, agrees to take delivery of the underlying commodity. The seller, known as the short, agrees to make delivery. Only a small number of contracts traded each year result in delivery of the underlying commodity. Instead, traders generally offset (a buyer will liquidate by selling the contract, the seller will liquidate by buying back the contract) their futures positions before their contracts mature. The difference between the initial purchase or sale price and the price of the offsetting transaction represents the realized profit or loss. Futures contracts trade in standardized units in a highly visible, extremely competitive, continuous open auction. In this way, futures lend themselves to widely diverse participation and efficient price discovery, giving an accurate picture of the market. To do this effectively, the underlying market must meet three broad criteria: The prices of the underlying commodities must be volatile, there must be a diverse, large number of buyers and sellers, and the underlying physical products must be fungible, that is, products are interchangeable for purposes of shipment or storage. All market participants must work with a common denominator. Each understands that futures prices are quoted for products with precise specifications delivered to a specified point during a specified period of time. Actually, deliveries of most futures contracts represent only a minuscule share of the trading volume; less than 1% in the case of energy. Precisely because the Exchange's physical commodity contracts allow actual delivery, they ensure that any market participant who desires will be able to transfer physical supply, and that the futures prices will be truly representative of cash market values. Most market participants choose to buy or sell their physical supplies through existing channels, using futures or options to manage price risk and liquidating their positions before delivery.
Why Use New York Mercantile Exchange Contracts?
s The contracts are standardized, accepted, and therefore liquid
financial instruments. s The Exchange offers cost-efficient trading and risk management opportunities.
Futures and options contracts are traded competitively on the Exchange in
an anonymous auction, representing a confluence of opinions on their values. s Exchange futures and options prices are widely and instantaneously
disseminated. Futures prices serve as world reference prices of actual transactions between market participants. s The Exchange's markets allow hedgers and investors to trade anonymously
through futures brokers, who act as independent agents for traders. s The liquidity of the market allows futures contracts to be easily liquidated prior
to required receipt or delivery of the underlying commodity. s While futures contracts are seldom used for delivery, if delivery is required,
financial performance is guaranteed, as it is for options that are exercised. Unlike principalto-principal transactions which must be continually examined for unexpected financial performance, counterparty credit risk is absent from transactions executed on the Exchange. s Futures and options contract performance is supported by a strong financial
system, backed by the Exchange's clearing members, including some of the strongest names in the brokerage and banking industries. s The Exchange offers safe, fair, and orderly markets protected by its rigorous
financial standards and surveillance procedures.
Commercial Applications of the Exchange's Energy Futures and Options Contracts
The Exchange provides buyers and sellers with price insurance and arbitrage opportunities that can be integrated into cash market operations. Trading Exchange contracts can improve the credit worthiness and add to the borrowing capacity of natural resource companies, thus augmenting the companies' financial management and performance capabilities.
Cash vs. Futures Price Relationships
Cash prices are the prices for which the commodity is sold at the various market locations. The futures price represents the current market opinion of what the commodity will
be worth at some time in the future. Under normal circumstances of adequate supply, the price of the physical commodity for future delivery will be approximately equal to the present cash price, plus the amount it costs to carry or store the commodity from the present to the month of delivery. These costs, known as carrying charges, determine the normal premium of futures over cash. As a result, one would ordinarily expect to see an upward trend to the prices of distant contract months. Such a market condition is known as contango and is typical of many futures markets. In most physical markets, the crucial determinant of the price differential between two contract months is the cost of storing the commodity over that particular length of time. As a result, markets which compensate an individual fully for carry charges interest rates, insurance, and storage are known as full contango markets, or full carrying charge markets. Under normal market conditions, when supplies are adequate, the price of a commodity for future delivery should be equal to the present spot price plus carrying charges. The contango structure of the futures market is kept intact by the ability of dealers and financial institutions to bring carrying charges back into line through arbitrage. Futures markets are typically contango markets, although seasonal factors in energy markets play an important role in market relationships. For example, during the summer, heating oil futures are often in contango as the industry begins to build inventory for the approaching cold weather. On any given day, prices in the forward contract months are progressively higher through the fall, reflecting the costs of storage, interest rates, and the assumption of increased demand. The opposite of contango is backwardation, a market condition where the nearby month trades at a higher price relative to the outer months. Such a price relationship usually indicates a tightness of supply; a market can also be in backwardation when seasonal factors predominate.
As a futures contract approaches its last day of trading, there is little difference between it and the cash price. The futures and cash prices will get closer and closer, a process known as convergence, as any premium the futures have had disappears over time. A futures contract nearing expiration becomes, in effect, a spot contract.
PRINCIPLES OF HEDGING AND PRICE DISCOVERY
Futures contracts have been used to manage cash market price risk for more than a
century in the United States. Hedging allows a market participant to lock in prices and margins in advance and reduces the potential for unanticipated loss. Hedging reduces exposure to price risk by shifting that risk to those with opposite risk profiles or to investors who are willing to accept the risk in exchange for profit opportunity. Hedging with futures eliminates the risk of fluctuating prices, but also means limiting the opportunity for future profits should prices move favorably. A hedge involves establishing a position in the futures or options market that is equal and opposite to a position at risk in the physical market. For instance, a crude oil producer who holds (is "long") 1,000 barrels of crude can hedge by selling (going "short") one crude oil futures contract. The principle behind establishing equal and opposite positions in the cash and futures or options markets is that a loss in one market should be offset by a gain in the other market. Hedges work because cash prices and futures prices tend to move in tandem, converging as each delivery month contract reaches expiration. Even though the difference between the cash and futures prices may widen or narrow as cash and futures prices fluctuate independently, the risk of an adverse change in this relationship (known as basis risk) is generally much less than the risk of going unhedged, and the larger a group of participants in the market, the greater the likelihood that the futures price will reflect widely held industry consensus on the value of the commodity. Because futures are traded on exchanges that are anonymous public auctions with prices displayed for all to see, the markets perform the important function of price discovery. The prices displayed on the trading floor of the Exchange, and disseminated to information vendors and news services worldwide, reflect the marketplace's collective valuation of what buyers are willing to pay and what sellers are willing to accept. The purpose of a hedge is to avoid the risk of adverse market moves resulting in major losses. Because the cash and futures markets do not have a perfect relationship, there is no such thing as a perfect hedge, so there will almost always be some profit or loss. However, an imperfect hedge can be a much better alternative than no hedge at all in a potentially volatile market.
One of the most common commercial applications of futures is the short hedge, or seller's hedge, which is used for the protection of inventory value. Once title to a shipment of a commodity is taken anywhere along the supply chain, from wellhead, barge, or refinery to consumer, its value is subject to price risk until it is sold or used. Because the value of a commodity in storage or transit is known, a short hedge can be used to essentially lock in the inventory value. A general decline in prices generates profits in the futures market, which are offset by a decline in the value of the physical inventory. The opposite applies when prices rise.
Example 1 Crude Oil Producer's Short Hedge
A crude oil producer agrees to sell 30,000 barrels a month for each of six months at the posted prices prevailing at delivery. When he agrees to the deal, posted prices are $20.50 a barrel, but as market conditions appear to be weakening, he wants to protect his revenues against a decline, and executes a short hedge. The example shows how the producer's revenue is protected from the full brunt of a declining market. In this example, the oil producer establishes hedges for the second, third, fourth, fifth, sixth, and seventh contract months against his production during the first, second, third, fourth, fifth, and sixth months ahead. Near-month futures positions are liquidated after a price posting is established (normally on the first day of the calendar month). In a surplus crude market, spot prices generally fall faster than postings, regardless of whether prices decline more slowly, as in Case 1, or more rapidly, as in Case 2.

If the producer could not lock in revenue, he could be faced with shutting in all or part of the production. The example shows two possible outcomes. Case 1, with relatively high posted and futures prices, and Case 2, with relatively low posted and futures prices. Short hedges for February, March, April, May, June, and July (against January, February, March, April, May, and June production) are initially established on December 1. Assuming the futures hedge is placed on December 1, the near-month contract is January and the second month out is February. Because the January crude futures contract expires three business days prior to December 24, and the posted prices for January are not finally established until January 2, the example attempts to have the liquidation of the futures coincide with the setting of the posted price. In summary, the nearby contract is used to hedge current production. For example, the February futures contract is utilized to hedge January production because the timing is better matched.
Example 2 Electricity Producer Fears a Price Decline
In this example, an independent power production company is at risk that falling prices will reduce profitability. It stabilizes cash flow by instituting a managed short hedging strategy on the electricity futures market. On February 1, the bulk power sales manager at a southeastern utility projects that he will have excess generation for the second quarter and notices attractive prices in the futures market for the April, May, and June contracts. The manager arranges to deliver this excess power at the prevailing market price in April, May, and June. However, he wants to capture the market prices now, rather than be exposed to the risk of lower prices in the spot markets. The action the utility takes to protect the company from this risk is to sell Entergy electricity futures contracts for those months. In the futures market, the producer sells 10 futures contracts for each of three months, April, May, and June at $23 per megawatthour (Mwh), $23.50, and $24, respectively. Assuming a perfect hedge, the futures sales realize $169,280 for the April contracts (10 contracts x 736 Mwh per contract x $23 per Mwh = $169,280), $172,960 for May contracts (10 x 736 x $23.50); and $176,640 for June contracts (10 x 736 x $24), for a total of $518,880. On March 29, the utility arranges to deliver 7,360 Mwh of April pre-scheduled power in the cash market, the equivalent of 10 contracts, at the current price which has fallen to $22 per Mwh, and receives $161,920. That is $7,360 less than budgeted when prices were anticipated at $23 per Mwh. Simultaneously, the producer buys back the April futures contracts to offset the obligations in the futures market. This also relieves it of the delivery obligation through the Exchange. The April contracts, originally sold for $23 ($169,280), are now valued at $22 per Mwh, or $161,920. This yields a gain in the futures market of $7,360. Therefore: The cash market sale of: A futures gain of: A net amount of: $161,920 (7,360 x $22/Mwh) plus $ 7,360 equals $169,280, or $23 per Mwh, the budgeted sum for April.
As cash prices continue to be soft for the second quarter, the hedge looks like this:
Cash Market Feb. 1 Futures Market Sells 10 Entergy electricity contracts in each of April, May, June for $23, $23.50, $24, respectively Sells 7,360 Mwh at $22 Sells 7,360 Mwh at $23 Sells 7,360 Mwh at $23.25 Buys back 10 April contracts, $22 Buys back 10 May contracts, $23 Buys back 10 June at $23

Financial Result Expected Revenue Cash Market Sales Rev Futures Mkt Gain (Loss) Actual Revenue
April $169,280 $161,920 $7,360 $169,280
May $172,960 $169,280 $3,680 $172,960
June $176,640 $171,120 $5,520 $176,640
Quarter $518,880 $502,320 $16,560 $518,880 $23.50 per Mwh
What happens to the power production company's hedge if prices rise instead of fall? In that case, assume the cash market rises to $24, $24.50, and $25. The power producer realizes $176,640 on the cash sale of 7,360 Mwh for April, but sold futures at $23 in February, and now must buy them back at the higher price, $24, if it does not want to stand for delivery through the Exchange. The 10 contracts are valued at $176,640 which is what the company must pay to buy them back, incurring a $7,360 loss on the futures transaction. Therefore: The cash market sale of: A futures loss of: A net amount of: $176,640 (7,360 x 24/Mwh) minus $7,360 equals $169,280, or $23 per Mwh, the budgeted sum for April.
As cash prices continue to be firm for the second quarter, the hedge looks like this:
Cash Market Feb. 1 Futures Market Sells 10 Entergy electricity contracts in each of April, May, June for $23, $23.50, $24, respectively Sells 7,360 Mwh at $24 Sells 7,360 Mwh at $24.50 Sells 7,360 Mwh at $25 Buys back 10 April contracts, $24 Buys back 10 May contracts, $24.50 Buys back 10 June at $25
Mar. 27 Apr. 26 May 26
Financial Result Expected Revenue Cash Market Sales Rev Futures Mkt. Gain (Loss) Actual Revenue
April $169,280 $176,640 ($7,360) $169,280
May $172,960 $180,320 ($7,360) $172,960
June $176,640 $184,000 ($7,360) $176,640
Quarter $518,880 $540,960 ($22,080) $518,880 $23.50 per Mwh
The average price of $23.50 per Mwh represents an opportunity cost of $1 per Mwh because cash market prices averaged $24.50 during the period of the hedge. The producer is comfortable with this because it is within the tolerance for risk that the risk management committee set at the time the positions were opened. Managing a hedge strategy is an evolving process. While hedges serve to stabilize prices, risk management targets can be reevaluated in future periods as market and financial circumstances change.
A long hedge is the purchase of a futures contract by someone who has a commitment to buy (is short) in the cash market. It is used to protect against price increases in the future. An end-user with a fixed budget, such as a manufacturing company that uses natural gas, can use a long hedge to establish a fixed cost. Sometimes the risk of an adverse change in the difference between cash and futures prices, also known as basis risk, can be an important consideration for hedgers of refined petroleum products.
A fuel marketer may offer customers fixed-price contracts for a number of reasons: to avoid the loss of market share to other marketers or alternative fuels, to expand market share; or to bid on municipal contracts requiring a fixed price. However, by offering to sell at a fixed price over a period of time, the marketer is exposed to the risk that wholesale costs will increase, perhaps to the point of unprofitability (Case 1). Thus, to fix his future acquisition costs, the marketer might implement a long hedge against a forward sales commitment. If his wholesale buying prices increase, profits on the futures market will offset the price increase in the cash market, keeping his retail margin constant. Similarly, if wholesale costs decrease, the lower acquisition costs will be offset by a loss on the futures (Case 2).
Example 3 Petroleum Marketer's Long Hedge, Rising and Falling Markets
On September 7, the New York Harbor price for heating oil is 55 and the cash market price at the fuel dealer's location is 54 a gallon, a 1 differential, or basis, between New York Harbor and the retailer's location. The dealer agrees to deliver 168,000 gallons to a commercial customer in December at 70 per gallon. On September 7, he buys four December heating oil contracts (42,000 gallons each) at 57, the price quoted that day on the Exchange's NYMEX Division. Total cost: $95,760 (42,000 x 4 x $0.57).
Case 1 Rising Prices On November 25, the fuel dealer buys 168,000 gallons in the cash market at the prevailing price of 59 a gallon, a 1 differential to the New York Harbor cash quotation of 60, Cost: $99,120. He sells his four December futures contracts (initially purchased for 57) at 60 a gallon, the current price on the Exchange, realizing $100,800 on the sale, for a futures market profit of $5,040 (3 a gallon). His cash margin is 11 (the difference between his agreed-upon sales price of 70 and his cash market acquisition cost of 59 for a total of $18,480 ($0.11 per gallon x 168,000 gallons).
Cash Market Sept. 7

Case 2 Falling Prices On November 25, the dealer buys 168,000 gallons at his local truck loading rack for 49 a gallon, the prevailing price on that day, based on the New York Harbor cash quotation of 50 a gallon. He sells his four December futures contracts for 50 a gallon, the futures price that day, realizing $84,000 on the sale, and experiencing a futures loss of $11,760 (7 a gallon).
Cash Market Sept. 7 Futures Market Buy four December heating oil futures at 57 per gallon Buys 168,000 gallons for 49 per gallon Sells four December heating oil futures for 50 per gallon
Cash margin of: A futures loss of: A total margin of:
$35,280 minus ($11,760) (7/gallon) equals $23,520 or 14/gallon
In summary, the fuel retailer guarantees himself a margin of 14 a gallon regardless of price moves upwards or down in the market. With the differential between cash and futures stable, as in Cases 1 and 2, spot-price changes in either direction are the same for both New York and the marketer's location. As a result, a decline in the futures price, which causes a loss in the futures market, is offset cent-for-cent by the increase in the cash margin.
Example 4 Utility Protects Acquisition Costs of Future Wholesale Purchases Without a Price Commitment From a Seller
On February 1, a utility in Ohio decides that the prices reflected in the futures market for the second quarter are less expensive than the company's marginal generating cost. The utility does not want to wait until the second quarter to buy power because it fears that its power acquisition costs may move significantly higher than its sales prices. The utility buys futures contracts for April, May, and June. Thus, to fix its acquisition costs, the utility might implement a long hedge against its forward sales. If wholesale buying prices, or production costs, increase, profits on the futures market will offset the rising costs in the cash market, keeping the retail margin constant. Similarly, if wholesale costs decrease, the lower acquisition costs will be offset by a loss in the futures market.
Case 1 Rising Prices On February 1, the utility in Ohio buys 10 Cinergy electricity futures contracts in each of three months, April, May, and June for $23, $23.50, and $24 per Mwh, respectively. The cost of the futures purchases are $169,280 for the total April contracts, $172,960 for May, and $176,640 for June, for a total cost of $518,880 to lock in an average cost of $23.50 per Mwh. On March 27, the utility buys 7,360 Mwh of its April power requirements in the Cinergy cash market (neutral basis) for the then prevailing price of $24 per Mwh, and pays $176,640. That is $7,360 more than it budgeted when it anticipated a price of $23 per Mwh. The utility also liquidates its futures positions by selling back its 10 April Cinergy futures contracts at the then-current price of $24 so it doesn't have to take delivery through the Exchange. Because nearby futures prices reflect the prevailing cash price, the price of the futures contracts it originally bought for $23 ($169,280), are now worth $24 ($176,640), yielding a gain in the futures market of $7,360. The cash market purchase of: A futures gain of: A net amount of $176,640 plus $7,360 equals $169,280, or $23 per Mwh, the budgeted sum for April.
As cash prices continue to be strong during the second quarter, the hedge looks like this:
Cash Market Feb. 1 Futures Market Buys 10 Cinergy electricity contracts in each of April, May, June for $23, $23.50, $24, respectively Buys 7,360 Mwh at $24 Buys 7,360 Mwh at $24.50 Buys 7,360 Mwh at $25 Sells back 10 April contracts, $24 Sells back 10 May contracts, $24.50 Sells back 10 June at $25

Quarter $518,880 $502,320 ($22,080) $518,880 $23.50 per Mwh
The average acquisition price of $23.50 per Mwh represents an opportunity cost of 75 per Mwh because cash market prices averaged $22.75 during the period of the hedge. The producer is comfortable with this because it is within the tolerance for risk that his risk management committee set at the time the positions were opened. Managing a hedge strategy is an ongoing process. While hedges serve to stabilize prices, risk management targets can be reevaluated in future periods as market and financial circumstances change.
Example 5 Trucking Company Hedges Diesel Purchases
On September 7, the cash market price of diesel fuel is 60 a gallon, exclusive of taxes, a five-cent differential, or basis, to the prevailing New York Harbor heating oil futures price of 55. A trucking company agrees to buy 168,000 gallons of diesel fuel in December at the prevailing futures price plus 5 per gallon. On September 7, it buys four December heating oil contracts (42,000 gallons each) at 57, the December price quoted that day on the Exchange's NYMEX Division. Total cost: $95,760. If futures prices are unchanged by the time it has to take delivery, the fuel cost will be 62 a gallon.
Case 1 Rising Prices On November 25, the company buys its December fuel allotment of 168,000 gallons in the cash market for 65 a gallon, 5 over the spot New York Harbor heating oil futures quotation of 60. Cost: $109,200. The company sells the four December futures contracts (initially purchased for 57) at 60 a gallon, the then current price on the Exchange, realizing $100,800 on the sale, for a futures market profit of $5,040 (3 a gallon). The effective cost of diesel fuel is 62 per gallon or $104,160 (the cash price of the fuel, less his three-cent gain in the futures market, when the contracts rose in price from 57 to 60).

Case 2 Falling Prices On November 25, the trucker buys 168,000 gallons at 54 a gallon for a cost of $90,720, the prevailing heating oil futures price of 49 plus 5 a gallon. He sells the four December futures contracts for 49 a gallon, realizing $82,320 on the sale, and experiencing a futures market loss of $13,440 (8 a gallon). The fuel cost, however, is only 54 a gallon, 8 less than the 62 that he would have paid had futures prices been unchanged when he entered the hedge. The loss on the futures position is offset by the gain in the physical market.

Hedging Strategies Involving Multiple Contracts
Strip trading is a flexible strategy that energy futures market participants use when hedging positions for several consecutive months forward. A market participant can lock in an average price for several months at a time by simultaneously opening a futures position in each of the months to be hedged through a single Exchange transaction. The average of the futures contracts over the period is the price level of the hedge. A six-month strip, for example, consists of an equal number of futures contracts for each of six consecutive contract months. Strip trades in the NYMEX Division futures contracts for light, sweet crude oil; heating oil; gasoline; natural gas; and electricity are executed as a single transaction during the open outcry trading session, after being bid and offered at an agreed-upon differential to the previous day's settlement price. The strip and the differential is calculated based on the average value of those months currently versus the average of the previous day's settlement prices for those months.
The ability to obtain an average price for multiple months enables a hedger to average his cash flow over a period of time. Positions can be hedged for as little as two consecutive months, or can go forward for up to 12 months in unleaded gasoline; 18 months in heating oil and electricity; 30 months in light, sweet crude oil; and 36 months in Henry Hub natural gas. The futures positions assumed in a strip trade are like any other futures position. Any single month's position can be liquidated by an offsetting futures trade, an exchange of futures for physicals (EFP), or, if desired, physical delivery through the Exchange clearinghouse. Strips let a hedger retain the flexibility to change a strategy by buying or selling additional futures contracts in any month, or liquidating the position of any month of the strip, something that cannot be done easily with over-the-counter instruments. Regular margin requirements apply to strip trades. The participant will be required to post and maintain margin levels for each month in the strip as if it were a separate position.
Example 6 Petroleum Refiner's Use Of A Strip Trade
A refiner anticipates the purchase of 60,000 barrels of crude oil, the volume distributed evenly over a six-month period beginning in October. The use of the strip allows the company to hedge its expenditures for crude oil evenly throughout the period. The refiner's risk management committee is comfortable with locking in this strip's price level over the period of their purchases, and, considering their fundamental view of the crude oil market, is even willing to pay a higher price, if necessary. The risk manager determines that those months are currently trading at an average that is 10 over the average of the previous day's settlement price, or $22.35. Assuming he wishes to hedge 100% of his physical requirements, he buys 10 contracts for each of the six months, or 60 contracts, representing 60,000 barrels, since each futures contract is for 1,000 barrels. The refiner's hedge, which has locked in a price of $22.35 for a total of 60,000 barrels over the period, looks like this:
Month OCT NOV DEC JAN FEB MAR Average
Transaction Price $22.54 $22.42 $22.35 $22.29 $22.26 $22.24 $22.35
Market Position Long 10 contracts Long 10 contracts Long 10 contracts Long 10 contracts Long 10 contracts Long 10 contracts
Assuming the refiner takes delivery from its traditional suppliers, it will liquidate the futures positions in the relevant months, offsetting its physical market transactions. If the refiner chooses, however, it can take delivery through the Exchange for any, or all, of the months involved in the strategy. As with any other hedge, there may be a loss in the futures market for a particular month that is compensated for by a gain in the cash market, conversely a gain in the futures market will offset a loss in the cash market. Regular margin requirements apply to strip trades. The participant will be required to post and maintain margin levels for each month in the strip as if it were a separate position.
Example 7 Petroleum Marketer's Long Hedge; Guaranteeing Retail Prices by Purchasing a "Strip" of Futures
By allowing market participants to lock in an average price over a period of time, strip trading strategies can be used by vendors of refined products to offer their customers seasonal price stability through fixed-price programs. These programs have become increasingly popular with heating oil retailers who are faced with increasingly competitive market conditions, and their customers, who desire stable pricing, thus avoiding the price spikes that can wreak havoc with household budgets. Retailers are able to offer seasonal fixed pricing with minimal risk to their operating margins by locking-in ahead of time during the off-season the price required to service customers during the winter. This can be accomplished with strips of NYMEX Division heating oil futures contracts. A retailer who wants to offer a fixed price program would in the spring and summer solicit as many customers as possible whose consumption averages 1,000 gallons each
over the period from October to the beginning of April, with the bulk of consumption occurring during December, January, and February. A large dealer typically sells about 10 million gallons in a season. Assume 20% of his customers choose to take advantage of the fixed price program, representing 2 million gallons, during the summer, he would buy a portfolio of futures contracts:
Customer Delivery Month October November December January February March Futures Contract Month November December January February March April Weighted average price: 50.28 per gallon Heating Oil Futures Price /gallon 50.02 50.77 51.17 50.92 49.87 48.92
During the period, he will need 50 futures contracts (representing 2.1 million gallons). However, he has to weight the volume toward the contract months of December, January, and February, which represent, say, 60% of the volume. He would buy five contracts per month for October, November, March, and April, and 10 per month for December, January, and February. As the distributor sells his product to his customers, he liquidates his futures contracts, one contract for each 42,000 gallons of product purchased.

Physical P&L Net Price
Several other factors must be taken into account in constructing a guaranteed price offering: transaction costs, the relationship between rack and futures prices, volume risk, and the dealer's operating costs and profit broken down to a cents-per-gallon figure. The retailers will hedge, that is, purchase their physical supply from their traditional suppliers while liquidating their futures positions. The difference between the rack price and the futures price is the basis. (In the New York area, for example, rack prices might be 2 per gallon over the futures price). The distributor must compare his own historical rack prices to futures prices. There are two important pieces to this analysis: The average difference, which represents the basis, and the standard deviation, a statistical measure of the variation of the basis around the average, which represents basis risk.) Components of Guaranteed Price Weighted Average Futures Price $0.5028

Spread positions offer another way of using futures. There are many types of spreads, but they all have two things in common. First, a spread always involves at least two futures positions, which are maintained simultaneously. For example, a trader may be long 10 June electricity contracts and short 10 September electricity contracts. Second, the price changes in the two or more legs of the position are expected to have a reasonably predictable relationship, and the potential profitability of the spread lies in that relationship or expected changes to that relationship. For example, the trader who is long 10 June contracts (the near-term contract) and short 10 September contracts (the distant contract) will benefit if market forces cause the near-term contract to make a larger advance than the more distant contract or if market forces cause the distant contract to drop more sharply than the near-term contract.
A petroleum refiner, like most manufacturers, is caught between two markets: the raw materials he has to purchase and the finished products he offers for sale. It is the nature of these markets for prices to be independently subject to variables of supply, demand, transportation, and other factors. This can put refiners at enormous risk when crude oil prices rise while refined product prices stay static or even decline, thus narrowing the spread. The Exchange facilitates crack spread trading by treating them as a single transaction for the purpose of determining a market participant's margin requirement. To calculate the theoretical refining margin, first calculate the combined value of gasoline and heating oil, then compare the combined value to the price of crude. Since crude oil is quoted in dollars per barrel and the products are quoted in cents per gallon, heating oil and gasoline prices must be converted to dollars per barrel by multiplying the cents per gallon price by 42 (there are 42 gallons in a barrel). If the combined value of the products is higher than the price of the crude, the gross cracking margin is positive. Conversely, if the combined value of the products is less than that of crude, then the cracking margin is negative. Using a ratio of two crude oil contracts to one gasoline contract plus one heating oil contract, the gross cracking margin is calculated as follows:
(Assume heating oil is $0.5450 per gallon, gasoline is $0.5750 per gallon and crude is $18.50 per barrel.) $0.5450 per gallon x 42 = $22.89 per barrel of heating oil $0.5750 per gallon x 42 = $24.15 per barrel of gasoline The sum of the products is: $47.04 Two barrels of crude ($18.50 x 2) = $37.00 Therefore, $47.04 - $37.00= $10.04 $10.04/2 = $5.02 (margin)
A refiner expects crude prices to hold steady, or rise somewhat, while products will fall. In this case, the refiner would "sell the crack;" that is, he would buy crude oil futures and sell gasoline and heating oil futures. Conversely, buying the crack means buying gasoline and heating oil and selling crude oil. Whether a hedger is selling the crack or buying the crack reflects what is done on the product side of the spread. Once the hedge is in place, the refiner need not worry about movements in absolute futures prices. He need be concerned only with how the combined value of products moves in relation to the price of crude oil. The following example shows a refiner locking in a margin between crude oil and heating oil.
Example 8 Fixing Refiner Margins Through Crack Spreads
In January, a refiner reviews his crude oil acquisition strategy and his potential distillate margins for the spring. In January, he sees that distillate prices are strong, and plans a two-month crude-todistillate spread strategy that will allow him to lock in his refinery margins. On January 22, the spread between April crude oil ($18 per barrel) and May heating oil (49.25 per gallon or $20.69 per barrel) presents what he believes to be a favorable $2.69 per barrel.
The refiner sells the April/May crude-to-heating oil spread, thereby locking in the $2.69 margin. In March, he purchases the crude oil for refining into products. Crude oil futures are $19 per barrel in March, $1 higher than the original crude oil futures position. Heating oil is trading at 49.50 per gallon ($20.79 per barrel), which equals a margin of $1.79. Had the refiner been unhedged, his margin would have totaled only the $1.79. Instead, the net margin from the combination of the futures position and the cash position is the $2.69 he originally sought.

Example 9 Refiner with a Diversified Slate, 3:2:1 Crack Spread
An independent refiner who is exposed to the risk of increasing crude oil costs and falling refined product prices runs the risk that his refining margin will be less than anticipated.
The refiner initiates a long hedge in crude oil and short hedges in heating oil and gasoline to fix a substantial portion of his refining margin. On September 15, the refiner incurs an obligation to buy 6,000 barrels of crude oil on May 16 at prevailing cash prices. He is also obliged to sell 84,000 gallons (2,000 barrels) of heating oil and 168,000 gallons (4,000 barrels) of gasoline on November 28 at prevailing spot prices. The crack spread has ensured that refining crude oil will be at least as profitable in November as it was in September, regardless of whether the actual cash margin narrows or widens. A decline in the cash margin is offset by a gain in the futures market; conversely, any gain in the cash market is offset by a loss in the futures market. The example assumes a crack spread of three crude oil, two gasoline, one heating oil.

Timing risk and basis risk can be quantified and are usually less than the absolute price risk to which the refiner is subjected. The example assumes fixed points in time of obligation to buy and sell in the cash market. In practice, these may not be entirely known or fixed.
Purchasing a Crack Spread
The purchase of a crack spread is the opposite of the crack spread hedge. It entails a short hedge in crude oil and long hedges in products. Refiners are naturally long the crack spread as they buy crude and sell products. At times, however, refiners do the opposite, they buy products and sell crude and thus find purchasing a crack spread a useful strategy. When refiners are forced to shut down for repairs, they often have to enter the crude oil and product markets to honor existing purchase and supply contracts. Unable to produce enough products to meet term supply obligations, the refiner must buy products at spot prices for resale to his term customers. Furthermore, lacking adequate storage space for incoming supplies of crude oil, the refiner must sell the excess on the spot market. If the refiner's supply and sales commitments are substantial and if he is forced to make an unplanned entry into the spot market, it is possible that prices might move against him. To protect himself from increasing product prices and decreasing crude oil prices, the refiner uses a short hedge against crude oil and a long hedge against products.
Similar to the crack spread, the "spark spread" has developed in the electricity markets as an intermarket spread for electricity and natural gas. The spark spread involves the simultaneous purchase and sale of electricity and natural gas futures contracts. This allows traders to take advantage of the generic conversions of natural gas to power to help price the forward electric power curve using natural gas-fired generation operating efficiencies and prices. The regions with the most transparent short-term natural gas to power price correlation typically have been the northwestern and southwestern United States and Texas. These areas coincide with the Palo Verde and COB electric power futures contracts trading on the Exchange. The gas to power correlation is not as good in other parts of the country where coal, oil, or nuclear are predominantly used on the margin.
The spark spread is a proxy for the heat rate (a measure of efficiency) of a specific generating unit or station (the number of Btus needed to make one kilowatt of electricity) multiplied by the cost of energy expressed in dollars per Btu. For example, if it takes 10,000 British thermal units, or Btus, to make one kilowatt of electricity, the formula can be simplified by multiplying the price per million Btus (MMBtu) by 10 to equate one MMBtu of natural gas to one megawatt hour (Mwh) of electricity. If the heat rate is 6,250, multiply by 6.25; if it is 19,000, multiply by 19. The accuracy of the spread evaluation is dependent on the market price for power which takes into account operating unit efficiencies. The market price reflects the relationship of the supply and demand for power. Generally, in an over-supplied power market, natural gas may not be the marginal cost energy source. Conversely, in a high-demand period, the cost of natural gas could be lower than the cost of oil, or aggregated, or even imported, power, however, all of the above may be on-line and generating electricity. Other costs affecting the price of power include those of gas transportation, power transmission, plant operations and maintenance, and fixed costs. Economic dispatch of the next lowest cost generation reflects a utility's ability to cover its costs plus a contribution to overhead based on the wholesale market price of power. The following example of a spark spread calculation shows the basic elements of pricing power using natural gas in the southwestern United States: Capacity charge per Mwh: Transmission to Palo Verde sub-station/Mwh: Heat rate: Natural gas price (El Paso Permian)/MMBtu: Natural gas transmission (burner tip add-on) Total power price per Mwh $2.50 $1.50 10,000 $2.45 $0.18 $20.30
Using the above values for natural gas at a 10,000 heat rate, the burnertip gas price (energy) equals [($2.45 + $.18) x 10] = $26.30 per Mwh. With the additional $4.00 per Mwh for capacity and transmission charges, the total price to generate power under this scenario is $30.30 per Mwh. (NOTE: This may not represent the market price.) The spark spread can also reflect the generation costs or anticipated generation costs of power for a specific facility. It can be used as a method of converting millions of Btus to megawatt hours and vice versa. As such, it relates well to the futures contracts for electricity and natural gas.
Because of the size difference of the contracts, the heat rate is an important factor in the arbitrage between natural gas futures and power futures. The eastern electricity futures contracts are for 736 Mwh per contract compared to natural gas of 10,000 MMBtus per contract. Using the (10,000 Btu/Mwh) heat rate method of converting Mwhs to MMBtus, one power contract will equate to 7,360 MMBtus or 0.736 natural gas contracts roughly a comparison of four power contracts to three natural gas contracts. At an 8,000 heat rate, the spark spread goes to a five-to-three relationship and, at 13,500 heat rate, the spread is close to a one-to-one relationship.
Example 10 Independent Power Producer Uses Spark Spread to Protect Margin
In April, an independent power producer (IPP) in the Southeast reviews his natural gas acquisition prospects and his potential electricity sales for the summer. He sees that while electricity prices are strong, natural gas is an economical buy. He believes that gas prices are likely to increase as the summer progresses which could erode his profit margin for electricity. The IPP plans a spread strategy that will allow him to lock a profit margin for his product. On April 25, the price of July NYMEX Division Henry Hub natural gas futures is $1.45 per million Btus and July Entergy electricity futures is $20 per megawatt hour (Mwh). He executes a spark spread to lock in a margin. Other relevant market data includes the following: The heat rate of the generating unit is approximately 8,000. This means it requires 8,000 Btus to generate one kilowatt hour of electric power. The heat rate can be simplified by multiplying the per-million-Btu-price of gas by eight to equate one MMBtu of natural gas to one Mwh. Because the natural gas and electricity contracts differ in size, the appropriate hedge ratio must be determined to capture the profit margin successfully. The hedge ratio depends upon the heat rate of the gas turbine.
Heat Rate Hedge Ratio Electricity/Nat Gas Contracts
8,000 10,000 12,000 13,500
0.59 0.74 0.88 0.99
5 to 3 4 to 3 9 to 8 1 to 1
The hedge ratio is determined by dividing the heat rate by 1,000, multiplying it by 736 (the size of the electricity contract in Mwh) and dividing it by 10,000 (the size of the natural gas contract in million Btus). Therefore, 8 x 736 = 5,888/10,000 = 0.59, giving it a ratio of five-to-three. By executing the following hedge, the electricity producer locks in a margin:
Spark Spread = [Electricity total value - natural gas total value]/electricity units Independent power producer places hedge on April 25, sells the spread: Apr. 25 Futures Transaction Sell five Entergy electricity futures Buy three Henry Hub natural gas futures [(5 x 736 Mwh x $26 per Mwh) - (3 x 10,000 MMBtu x $2.45 per MMBtu)]/(5 x 736 per Mwh) $6.03 per Mwh
Independent power producer lifts the hedge on July 28, buys the spread July 28 Futures Transaction Buy five Entergy electricity futures Sell three Henry Hub natural gas [(5 x 736 Mwh x $23 per Mwh) - (3 x 10,000 MMBtu x $2.65 per MMBtu)]/(5 x 736 Mwh) $1.40 per Mwh $6.03 - $1.40 = $4.63 per Mwh, net profit $4.63 per Mwh x (5 x 736 Mwh) = $17,038.40
Result of hedge:
By buying natural gas futures at a relatively low price and selling electricity futures at a relatively high price, the independent producer sold the spread, hedging his profit margin for a physical sale. The power producer will be selling the electricity futures, therefore selling the spread. To lift the hedge, the opposite will be true, that is, buying the spread (buying the electricity futures). In the cash market, the cost of gas transportation, electricity capacity, and transmission charges also must be factored in when determining the delivered price of electricity. The natural gas cash market in April looked like this:
Price of natural gas at Henry Hub based on Henry Hub natural gas futures: Current cost of gas transmission to power plant: Total projected cost of gas $2.63 x 8 (heat rate) = Present electric capacity charge Present electric transmission to Entergy Total power cost at Entergy $2.45 per million Btu $0.18 per million Btu $2.63 per million Btu $21.04 Mwh equiv. gas price $2.50 per Mwh $1.50 per Mwh $25.04 per Mwh
In July, the power producer must take delivery of physical gas and sell his electricity at the current cash market prices, while incurring the current transportation charges for gas and the capacity and transmission charges for electricity. By this time, market conditions have dramatically changed. Gas prices have begun spiking up, as electricity prices are tumbling because of an abundance of coal-fired power in the region. When the power producer bought natural gas futures and sold electricity futures in April, he locked in a margin of $6.03 per Mwh. In July, he must offset his positions by selling back on the Exchange the gas futures that he purchased and by buying back the electricity futures that he sold. Because natural gas prices increased and electricity fell, the net margin, the differential between the two also fell. He is left with a net margin, of $4.63 per Mwh. Meanwhile, in the July cash market, natural gas and gas transportation increased, too:
Buy gas at Transportation $2.85 x 8 = Electric capacity and transmission Total power cost $2.65 $0.20 $22.80 Mwh equivalent price of gas $4.00 $26.80 per Mwh
The independent power producer was much better off hedging, which enabled him to lock in a net margin of $4.63, after he offset his futures positions. In the cash market, the favorable natural gas to electricity relationship that existed in April had reversed by July, relative to electricity futures pricing.
Natural gas and propane are also likely candidates for a market-related spread since natural gas processing is a major source of propane production. The natural gas processor can partially hedge the price risk of processing natural gas and extracting propane through the use of a fractionation spread, much the same way refiners use crack spreads to establish margins when refining crude oil into heating oil and gasoline.
Balancing the Frac Spread by Equating Heating Value
The frac spread is quoted in heating value terms, dollars per million British thermal units (MMBtu), to equate propane to natural gas. The natural gas futures contract is composed of 10,000 MMBtu, and is quoted in dollars and cents per MMBtu. Propane is quoted in cents per gallon. One gallon in gaseous form contains approximately 91,500 Btus. Dividing the price of propane by 0.0915 gives the equivalent price per MMBtu. If propane were trading at 35 per gallon, the cost would be $3.825 per MMBtu. One propane futures contract, 42,000 gallons, represents about 38% of the heating value of one natural gas contract of 10,000 MMBtu. The two most popular ratios used to create a balance heating value position are a 3:1 or 5:2 propane to natural gas spread. Once the price of propane, quoted in dollars per gallon, has been converted into the price per MMBtu, the frac spread can be calculated by subtracting the price of natural gas from the calculated value of propane to yield the gross manufacturing margin. At this point, the fractionator has only paid for the value of natural gas consumed, or reduced, in processing. There are many additional costs including processing, transportation, fractionation, and marketing that must be paid out of the gross manufacturing margin.
Example 11 Gas Processors Frac Spread with a 5:2 Ratio
Assume propane futures are trading at 47 per gallon ($5.136 per MMBtu). If natural gas futures were trading at $3.086 per MMBtu, then the frac spread would have a positive margin of $2.05. From this margin, other operating costs could be covered. The most frequent application of frac spreads is found among gas processors. In the example below, a processor wishes to lock in the $2.05 per MMBtu spread between the two products for the March contract. He enters into the market on December 3, and liquidates his position on February 10, several days before the March contract ceases trading.

Profit per MMBtu = $.034
A profit of 34 per MMBtu on 19,215 MMBtu is realized in the futures market. In March, the gas processor can no longer realize the high margin he received in December for fractionating propane and "dry" natural gas out of wet gas. The 34 per MMBtu futures gain is used to supplement, or offset, the reduced processing margin received in the cash market. The net effect on the processor's balance sheet is a maintained margin.
If the frac spread had increased beyond $2.05 instead of decreasing, the processor would have lost an opportunity for further gain but, as a hedger, he was content in locking in the $2.05 per MMBtu margin. He was willing to forego a potentially higher margin in exchange for eliminating the chance of a lower margin.
As noted earlier, futures contracts are standardized instruments that stipulate the quantity, quality, and delivery points for a wide cross section of the underlying industry. Basis is the differential that exists between the cash price of a given commodity and the price of the nearest futures contract for the same, or a related commodity. The predictability and size of the basis can involve three price relationships: s The difference between the futures contract and the spot price of the underlying commodity. s The difference between the price at the futures contract delivery point and the price at a different location. s The price at the futures contract delivery point and the price of a similar, but not identical, quality commodity at the same location. The cash/futures basis can be effectively minimized if delivery is made or accepted at the same time that the trading of a futures contract nears expiration. Because of price convergence, a futures contract nearing expiration becomes, in effect, a spot contract. Locational basis is a consideration for firms that desire to hedge but do not make deliveries at the futures contract location. In theory, the price relationship between two different markets will be based on the cost of transportation between them. Sudden local shifts in supply or demand, however, can distort this price relationship. The extent to which these changes in relative market conditions are predictable will determine the hedged firms' exposure to locational basis risk. Product basis concerns those firms that seek to hedge the purchase or sale of a specific commodity not offered as a liquid futures contract. Firms base their hedge on the historical relationship of the commodity underlying the contract to the commodity to be hedged. For example, the NYMEX Division heating oil futures contract is widely used as a hedging proxy for jet fuel, since the products are chemically similar and often trade within a narrow price range in relation to each other. The NYMEX Division light, sweet crude oil futures contract, likewise, is used to hedge crudes not specified for delivery by the contract, but which nevertheless trade at a high correlation to the futures contract. (Figures 2 to 12).

For the futures trader, the critical period for assessing basis is between the time that the futures transaction is entered into and the time it is closed, or liquidated. If a short hedger (a seller of futures) experiences a widening in the basis during the time the hedge is held, a basis loss may result. This narrowing means that cash prices have declined relative to futures prices. That is, they have fallen more or risen less than futures prices. The short hedger's cash loss in a declining market would exceed the gain on the short futures transaction. Or, conversely, the cash gain in a rising market would be exceeded by the loss on the futures transaction. On the other hand, a basis gain would occur in the case of a long hedge and a widening basis because the futures price would rise relative to the cash price. Thus, a narrowing basis yields gains for the short hedger and losses for the long hedger.
Potential Basis Changes:
RISING MARKET Cash/Futures Position Bought the cash/ sold the futures Sold the cash/ bought the futures Cash Rises Less Than Futures Loss Gain Cash Rises More Than Futures Gain Loss FALLING MARKET Cash Falls Less Than Futures Gain Loss Cash Falls More Than Futures Loss Gain
Example 12 Effect of Basis on a Fuel Dealer's Hedge
On September 7, the cash market price at a fuel dealer's location is 54 a gallon. The New York Harbor price is 55. The dealer agrees to deliver 168,000 gallons to a commercial customer in December at 70 per gallon. On September 7, he buys four December heating oil contracts (42,000 gallons each) at 57, the price quoted that day on the Exchange's NYMEX Division. Total cost: $95,760.
CASE 1: Rising Prices, Improving Basis On November 25, the fuel dealer's local wholesale market price is 59 a gallon (based on a New York Harbor price of 65), yielding a cash margin of 11. Four December futures contracts, representing 168,000 gallons (initially purchased in September for 57 a gallon), are sold for 65, a total of $109,200. The futures profit is $13,440. Cash margin is: Futures profit of: Total margin of: Less operating expenses: Profit: $18,480 plus $13,440 equals $31,920 or 19/gallon ($16,800) (10/gallon) $15,120
CASE 2: Falling Prices: Worsening Basis (Futures decline faster than cash prices) November 25: The dealer buys 168,000 gallons at 50 a gallon in the local cash market, based on New York Harbor price of 49. The cash margin is 20 a gallon or $33,600. He sells the December futures contracts for 49 a gallon, for a total of $82,320, incurring a futures loss of $13,440 (8/gallon). Cash margin is: A futures loss of: Yielding a total margin of: Less operating costs of: Profit of: $33,600 or 20/gallon minus ($13,440) (8/gallon) $20,160 or 12/gallon ($16,800) (10/gallon) $3,360 or 2/gallon
The perfect hedge is a rarity, and some basis risk will almost always be present. While the worsening basis position (a widening differential) of the above example can cause adverse results, usually it is far better to be hedged and to be at risk for the differential than it is to be at risk for the entire barrel.
Exchange of Futures for Physicals (EFPs)
The Exchange estimates that more than 95% of all energy futures contracts do not directly result in physical delivery. Companies who do choose to deliver, however, have several options. They can choose standard delivery, attempt to arrange an Alternative Delivery Procedure (ADP) or effect an Exchange of Futures for Physicals (EFPs). (Figure 13).
Exchange of Futures for Physicals
The NYMEX Division energy futures contracts explicitly set forth delivery locations and other terms. With an ADP, however, buyer and seller may agree to consummate delivery under terms different from those prescribed in the futures contracts, after the two parties have been matched for delivery by the Exchange following the termination of trading. In ADP transactions, market participants release both the Exchange and their clearing members from all liabilities related to the delivery negotiated between parties. Companies using energy futures contracts for hedging purposes are often not interested in making or taking delivery at the specified locations. In many cases, they are not interested in being matched to
s Natural Gas s NY Harbor Unleaded Gasoline s Heating Oil s Crude Oil
a trading partner by the Exchange. More often than not, a hedger using futures finds it economically desirable to make or take delivery elsewhere, under terms that differ from those of the futures contract.
EFPs provide the mechanism for such transactions and, based on frequency, is the preferred method of delivery because it provides greater flexibility. EFPs allow companies to choose their trading partners, delivery site, the grade of product to be delivered, and the timing of delivery. The EFP mechanism allows buyers and sellers to effect their cash market transaction on the basis of negotiated price. However, the quantity of the cash commodity involved in an EFP must be approximately equal to the quantity specified by the number of futures contracts involved in the EFP. After both parties to an EFP agree to such a transaction, the price at which the EFP is to be cleared is submitted to the Exchange. This is the nominal price of the EFP. The EFP parties can then effect the actual physical exchange at a price they negotiate between themselves.
Mechanics of an EFP
EFPs can be effected between two futures market participants a long and a short hedger provided there is a physical market transaction between the parties. For example, a futures market long (a buyer) would take delivery of crude oil from a futures market short (the seller) with whom the EFP is conducted. In this transaction, the buyer's hedge is liquidated, as is the seller's, and the actual transfer of crude oil occurs between the parties (Example 13).
Example 13 EFP to Initiate a Position
On August 7, an oil refiner who wishes to protect a portion of his products inventory wants to sell to protect against falling prices. At the same time, a diesel fuel distributor is concerned about rising prices and looks to buy to protect his forward purchases. They agree to a price of diesel fuel, net the basis, and register the EFP with the Exchange. Once registered, both parties have instituted futures positions at a price which reflects the exact basis between NYMEX Division heating oil futures and the regional rack price for diesel fuel. On September 16, the diesel refiner arranges with the distributor for the physical delivery of the fuel. At that time, the refiner and the distributor independently offset their futures positions on the Exchange. In this example, the long and short hedgers have "swapped" futures obligations (thus terminating their contract obligations on the Exchange before their futures contracts mature) in consideration of their exchange of physical market positions. The transaction occurs at the price, location, and time negotiated by the parties. In order to engage in an EFP, it is not necessary for both sides to be in the futures market when the EFP is initiated except during EFP-only sessions. A futures market long, for example, might effect an EFP with a cash market long. The net result of the transaction would be delivery of a commodity to the futures hedger and the assumption by the physical market participant of the hedger's futures market contracts (Example 14).
Example 14 Use of an EFP to Liquidate a Position
On August 7, a diesel distributor wants to cover forward purchases, so he buys 25 contracts of October heating oil futures on the Exchange at a price of 59 per gallon. At about the same time, a refiner seeking to protect his refined product inventory sells 25 October heating oil futures at a price of 59.15 per gallon. On September 16, the two companies agree to a cash deal for 25,000 barrels (1,050,000 gallons) of diesel, the equivalent of 25 contracts. Since both companies have hedge positions, they agree to close out those positions by use of an EFP. Since they can register the EFP with the Exchange at any price that they agree to, they agree to use a price that is equal to the exact basis of their delivery point and the price quoted on the Exchange.
By using the EFP, the hedge was taken off using the exact basis. This avoided the possible market risk of covering the hedge in the open market at the Exchange where there is no guarantee as to the price at which the hedge would be liquidated. The above transaction is fairly straightforward. For example, a futures market long (a cash market short) receives heating oil from a firm selling the commodity in the physical market (a cash market long). The obligation of the futures market long to take delivery of heating oil in New York Harbor is then ended. The firm selling the heating oil to the hedger would then assume a new long futures position as of the date the EFP is posted at the Exchange. The seller of heating oil then has three choices: (1) sell futures to liquidate its new futures position; (2) let the contracts mature and take delivery of the heating oil in New York Harbor; or (3) locate another firm willing to engage in an EFP. Because EFPs might involve deliveries to points other than those specified in the contracts, and/or different energy commodities, and/or different delivery periods, transaction prices must be negotiated between parties to the EFPs. These negotiated prices could reflect differentials based on quality, location, and timing, including transportation and quality differentials between the two products, and delivery points. In an EFP where gasoline is delivered in Houston, negotiated prices might be a function of the location differential: delivery in Houston instead of New York Harbor. Similarly, a delivery of jet fuel to Chicago might be based on the product and location differentials: Chicago vs. New York Harbor and jet fuel vs. heating oil. The Exchange clearinghouse treats EFPs as trades for margining purposes. Once the EFP is effected, margin funds can be released on the business day following the posting of the EFP. In EFPs involving a futures market hedger and a physical product market participant that initially is not holding a futures position, the hedger's margin funds are released on the business day following the EFP posting. The physical market participant then becomes responsible for maintaining the account established for margin funds until the hedge is liquidated or delivery of the contracts is made. EFPs can be negotiated at the time a particular energy futures contract trades or until 2 P.M. of the business day following the termination of trading in an expired contract for crude oil, petroleum products, and electricity, and two hours after the termination of trading in the natural gas contracts. After both parties to an EFP agree to such a transaction, the Exchange must be notified of their intention to effect the EFP through the parties' clearing members. The Exchange requires written documentation on EFPs and provides standardized forms for this purpose. Information to be supplied includes:
s The fact that an EFP transaction is being effected. s A statement that the EFP has resulted in a change in ownership of a particular energy commodity. s The date the transaction occurred. s The type and quantity of the energy futures involved in the EFP transaction. s The price at which the futures transaction is to be cleared. s The names of the clearing members involved in the EFP. The buyer's and seller's clearing members must satisfy the Exchange that the transaction is a legitimate EFP. Evidence of a change in ownership of the cash commodity involved in the EFP (or a commitment for such a change), as well as payment received by the firm selling the product, must be made available to the Exchange and secured by the clearing members representing the parties to the EFP upon specific request from the Exchange's compliance department.
Blind vs. Selective Hedge
The term "blind hedge" refers to the practice of not deviating from a fully planned hedging strategy, with volumes, contracts, and entry and exit points established prior to the execution of the hedge. In a selective hedge, the execution of the overall strategy can be fine-tuned to better reflect ongoing cash market conditions. Thus, if a third case of continuously increasing postings were assumed, it is unlikely that the producer would blindly stick to his losing short hedges, rather than liquidate early to contain his future losses. A selective hedge, for example, might link the volume to be hedged to an ongoing assessment of the cash-futures basis relationship and the perceived likelihood of a reduction in posted prices.
The word "technical" is often used in connection with the action of prices in the futures market. Often heard phrases are: the market declined because of a "technical reaction," it went up on a "technical rally," the market is "technically weak" or "technically strong." Technical is used to mean a price movement based on a continuation of, or deviation from, an observed price pattern.
The market price of a specific commodity is considered by technical traders to be the most important determinant of the environment which will affect futures prices. Through the use of the information revealed from charting daily futures prices, technicians attempt to make accurate predictions regarding futures price behavior.
Charting Price Trend Lines
Charting is the practice of recording, in graph format, the market price movements of a particular commodity over time with the objective of defining price levels at which commodities should be bought or sold. Daily price movements are plotted as high, low, and closing prices to help the trader determine trends, resistance points at which prices should not be easily exceeded, and support points below which prices should not easily fall. These technical signals are used by traders to indicate when to buy or sell. Trend lines are the simplest form of technical analysis. Connecting a series of high points to draw a downtrend can give the trader his first set of clues to current market direction. Using lows and highs together, in either direction, will yield a price channel between the two lines, indicating if and when a piece breakout beyond the channel may occur. Moving averages represent a more complex way of identifying these underlying trends. Technical traders always trade with the trend, never against it. While there will always be moderate rallies in downtrends and moderate reactions in uptrends, countertrend movement is seldom sustained. A variety of patterns have been identified to help recognize changes in a trend. Chart patterns have been variously described as "double tops," (when the market rises but hits resistance at a certain level, retreats, rises again, but still cannot breach the previous resistance point, and falls back again); "double bottoms," an inverse pattern that shows resistance to a falling market; "head-and-shoulder formations," again the same general pattern, but with the resistance points being hit at succeedingly lower (or higher) levels; "triangular flag patterns," when the market consolidates sideways; and "price gaps," when the low price of one bar on a chart is higher than the high of the preceding bar (or inversely, the high is lower than the low of the preceding bar, a price or price range where no trades take place). Other techniques and terms which are commonly used in technical analysis include: s Historical Volatility: Analysis of a commodity's past price variability based on time frame (for example, 20-day) and price interval.
s Moving Average: Moving average (open, high, low, close, midpoint, average) to follow the trend signal data fluctuations, and signal long and short positions. s Ratio: Despite large fluctuations in price, many commodities have price relationships. By calculating and analyzing their ratio, overvalued and undervalued markets can be found. s Rate of Change: Monitors and calculates the market's rate of change relative to previous trend intervals, as specified in the value input (also known as peaks and valleys). s Relative Strength Index (RSI): Study to measure the market's strength and weakness. A high RSI (>70) indicates an overbought or weakening market, and a low RSI (<30) an oversold, bear market. s Stochastic Oscillator: A computer-generated overbought/oversold indicator whose traditional interpretation is similar to that of the RSI. A high stochastic reading (>80) indicates an overbought, or weakening, market and a low reading (<20) indicates an oversold market. s Support/Resistance/Reversal: Levels determined through technical analysis that indicate trading support, resistance, or the reversal (inverse) of a market price in a specific time frame. Interested readers can familiarize themselves with the concepts of technical trading through various books and periodicals on the subject.
Volume and Open Interest
Figures for volume and open interest are also important and widely used technical trading tools. Volume refers to the total number of trades in a particular commodity futures contract on a given day. Increasing volume is generally considered an indication that the current price trend is strong and likely to continue. Changes in average volume figures are seen as indicating when major high or low points in a market are being approached. Technical traders believe volume will increase rapidly as these points are approached. Open interest refers to the number of long and short positions in a specific contract which have not been liquidated or offset by an opposing purchase or sale by the same participant. Increasing open interest figures are considered supportive of the underlying price trend. That is, they may indicate market strength during periods of rising prices, or the support of a downward trend during periods of market weakness. Similarly, decreasing open
interest figures during rising price trends are seen to indicate a technical weakness in the market a possible dip or reversal based upon the liquidation of long open interest. Open interest is also an indicator of commercial use of a futures contract. The combination of volume and open interest figures, used in conjunction with a major technical analysis system, can provide useful information that traders can factor into their decision-making process. Parallel or inverse relationships between volume and open interest can be analyzed to determine the degree of support which may exist for a specific price trend.
Options on futures offer additional flexibility in managing price risk. There are two
types of options, calls and puts. A call gives the holder, or buyer, of the option the right, but not the obligation to buy the underlying futures contract at a specific price up to a certain time. A put gives the holder the right, but not the obligation to sell the underlying futures contract at a specific price up to a certain time. A call is purchased when the expectation is for rising prices; a put is bought when the expectation is for neutral or falling prices. The target price at which a buyer or seller purchases the right to buy or sell the options contract is the exercise price or strike price. The buyer pays a premium, or the price of the option, to the seller for the right to hold the option at that strike. An options seller, or writer, incurs an obligation to perform should the option be exercised by the purchaser. The writer of a call incurs an obligation to sell a futures contract and the writer of a put has an obligation to buy a futures contract. An option is a wasting asset. The premium declines as time passes. Depending upon the movement of an option's price, the buyer will choose one of three alternatives to terminate an options position: Exercise the option; liquidate it by selling, or buying, it back on the Exchange; or let it expire without value. Options give hedgers the ability to protect themselves from adverse price moves while participating in favorable price moves. If the options contract expires worthless, the only cost is the premium. Many people think of buying options like buying insurance. By using options alone, or in combination with futures contracts, strategies can be devised to cover virtually any risk profile, time horizon, or cost consideration.
Options Rights and Obligations
Has the right to buy a futures contract at a predetermined price on or before a defined date. Expectation: Rising prices Grants right to buyer, so has obligation to sell futures at predetermined price at buyer's discretion. Expectation: Neutral or falling prices
Has right to sell futures contract at a predetermined price on or before a defined date. Expectation: Falling prices Grants right to buyer, so has obligation to buy futures at a predetermined price at buyer's discretion. Expectation: Neutral or rising prices
Determinants of an Options Premium
In return for the rights they are granted, options buyers pay options sellers a premium. The four major factors affecting the price are: s Futures price relative to options strike price s Time remaining before options expiration s Volatility of underlying futures price s Interest rates As in the futures market, options trading takes place in an open outcry auction market on the floor of the Exchange or after-hours on NYMEX ACCESS. While the value of futures is tied to the underlying cash commodity through the delivery process, the value of an option is related to the underlying futures contract through the ability to exercise the option.
Strike Price vs. Futures Price
Strike prices are listed in various increments, depending upon the contract. The most important influence on an option's price is the relationship between the underlying futures price and the option's strike price. Depending upon futures prices relative to a given strike price, an option is said to be at-the-money, in-the-money, or out-of-the-money. An option is at-the-money when the strike price equals the price of the underlying futures contract. An option is considered in-the-money when the price of the futures contract is above a call's strike price, or when the futures price is below a put's strike price. An in-the-money option has intrinsic value. A call is out-of-the-money when the futures price is less than the options strike price. For example, when the December electricity futures price is $18 per megawatt hour, the December $19 call grants the holder of the options contract the right to buy a December futures contract at $19 even though the market is at $18. A put is out-of-the-money when the underlying futures price is higher than the put's strike price.
An option's premium will usually equal or exceed whatever intrinsic value the option has, if any. Intrinsic value is the amount by which an option is in-the-money.
Premium - Intrinsic Value = Time Value Call Premium = Time Value + Intrinsic Value Put Premium = Time Value + Intrinsic Value
An options time value is the amount buyers are willing to pay for the option above its intrinsic value. Out-of-the-money options carry all time premium since their intrinsic value is zero, as do at-the-money options. As an option becomes deeply in- or out-of-the-money, the time premium shrinks. As an options contract approaches expiration, or volatility decreases, time value decreases. It is important to note that time value is equal for the same strike and same expiration for both calls and puts. The time value of an option shrinks as the expiration date approaches, all other factors being equal. The reason is that there is less and less time for a major change in market behavior, and a decreasing likelihood that the option will change in value.
Options prices are linked to futures prices through the exercise feature. If at the call option's expiration, futures are trading at $17, a $16 call is worth $1, intrinsically the difference between the futures price and the strike price. This is because the holder of a $16 call can exercise his option, receive a long futures position at $16, immediately turn around and sell the futures contract for $17, and make $1. This is known as trading at parity. If the call is only trading at, say, 30, then a trader can buy $16 calls, exercise them into long futures at $16, sell them for $17 and make a risk-free 70, exclusive of transaction costs. Market forces ensure that an opportunity like this cannot last long. The o...
