1. WHY WE NEED FOREIGN EXCHANGE
Almost every nation has its own national
currency or monetary unitits dollar, its peso,
its rupeeused for making and receiving
payments within its own borders. But foreign
currencies are usually needed for payments
across national borders. Thus, in any nation
whose residents conduct business abroad or
engage in financial transactions with persons in
other countries, there must be a mechanism for
providing access to foreign currencies, so that
payments can be made in a form acceptable to
foreigners. In other words, there is need for
foreign exchange transactionsexchanges of
one currency for another.
2. WHAT FOREIGN EXCHANGE MEANS
Foreign exchange refers to money denominated in the currency of another nation or
group of nations. Any person who exchanges
money denominated in his own nations
currency for money denominated in another
nations currency acquires foreign exchange.
That holds true whether the amount of the
transaction is equal to a few dollars or to
billions of dollars; whether the p erson
involved is a tourist cashing a travelers check
in a restaurant abroad or an investor
exchanging hundreds of millions of dollars for
the acquisition of a foreign company; and
whether the form of money being acquired
is foreign currency notes, foreign currencydenominated bank deposits, or other shortterm claims denominated in foreign currency.
A foreign exchange transaction is still a shift
of funds, or short-term financial claims, from
one country and currency to another.
Thus, within the United States, any money
denominated in any currency other than the
U.S. dollar is, broadly speaking, foreign
exchange.
Foreign exchange can be cash, funds available
on credit cards and debit cards, travelers checks,
bank deposits, or other short-term claims. It is
still foreign exchange if it is a short-term
negotiable financial claim denominated in a
currency other than the U.S. dollar.
But, in the foreign exchange market described
in this bookthe international network of major
foreign exchange dealers engaged in high-volume
trading around the worldforeign exchange
transactions almost always take the form of an
exchange of bank deposits of different national
currency denominations. If one bank agrees to
sell dollars for Deutsche marks to another bank,
there will be an exchange between the two parties
of a dollar bank deposit for a DEM bank deposit.
In this book, foreign exchange means a bank
balance denominated in a foreign (non-U.S.
dollar) currency.
3. ROLE OF THE EXCHANGE RATE
The exchange rate is a pricethe number of units
of one nations currency that must be surrendered
in order to acquire one unit of another nations
currency. There are scores of exchange rates
for the U.S. dollar. In the spot market, there is an
exchange rate for every other national currency

traded in that market, as well as for various
composite currencies or constructed monetary
units such as the International Monetary Funds
SDR, the European Monetary Unions ECU,
and beginning in 1999, the euro. There are
also various trade-weighted or effective rates
designed to show a currencys movements against
an average of various other currencies (see
Box 2-1). Quite apart from the spot rates, there
are additional exchange rates for other delivery
dates, in the forward markets. Accordingly,
although we talk about the dollar exchange rate in

BILATERAL AND TRADE-WEIGHTED
EXCHANGE RATES
Market trading is bilateral, and spot and
forward market exchange rates are quoted
in bilateral termsthe dollar versus the
pound, franc, or peso. Changes in the
dollars average value on a multilateral
basis(i.e., its value against a group or
basket of currencies) are measured by
using various statistical indexes that have
been constructed to capture the dollars
movements on a trade-weighted average,
or effective exchange rate basis. Among
others, the staff of the Federal Reserve
Board of Governors has developed and
regularly publishes such indexes, which
measure the average value of the dollar
against the currencies of both a narrow
group and a broad group of other
countries. Such trade-weighted and
other indexes are not traded in the OTC
spot or forward markets, where only
the constituent currencies are traded.
However, it is possible to buy and sell
certain dollar index based futures and
exchange-traded options in the exchangetraded market.
the market, and it is useful to do so, there is no
single, or unique dollar exchange rate in the
market, just as there is no unique dollar interest
rate in the market.
A market price is determined by the interaction of buyers and sellers in that market, and a
market exchange rate between two currencies is
determined by the interaction of the official and
private participants in the foreign exchange rate
market. For a currency with an exchange rate that
is fixed, or set by the monetary authorities,
the central bank or another official body is a key
participant in the market,standing ready to buy or
sell the currency as necessary to maintain the
authorized pegged rate or range. But in the United
States, where the authorities do not intervene in
the foreign exchange market on a continuous
basis to influence the exchange rate, market
participation is made up of individuals,
nonfinancial firms, banks, official bodies, and
other private institutions from all over the world
that are buying and selling dollars at that
particular time.
The participants in the foreign exchange
market are thus a heterogeneous group. Some
of the buyers and sellers may be involved in
the goods market, conducting international
transactions for the purchase or sale of
merchandise. Some may be engaged in direct
investment in plant and equipment, or in
portfolio investment, dealing across borders
in stocks and bonds and other financial
assets, while others may be in the money
market, trading short-term debt instruments internationally. The various investors,
hedgers, and speculators may be focused on
any time period, from a few minutes to several
years. But, whether official or private, and
whether their motive be investing, hedging,
speculating, arbitraging, paying for imports,
or seeking to influence the rate, they are all
part of the aggregate demand for and supply

of the currencies involved, and they all play a
role in determining the market exchange rate
at that instant.
Given the diverse views, interests, and
time frames of the participants, predicting
t he future course of exchange rates is a
particularly complex and uncertain business.
At the same time, the since exchange rate
influences such a vast array of participants
and business decisions, it is a pervasive
a nd singularly important price in an
open economy, influencing consumer prices,
investment decisions, interest rates, economic
growth, the location of industry, and
much else. The role of the foreign exchange
market in the determination of that price is
critically important.
4. PAYMENT AND SETTLEMENT SYSTEMS
Just as each nation has its own national
currency, so also does each nation have
its own payment and settlement system
that is, its own set of institutions and
legally acceptable arrangements for making
payments and executing financial transactions within that country, using its national
currency. Payment is the transmission of an
instruction to transfer value that results from a
transaction in the economy, and settlement
is the final and unconditional t ransfer of
the value specified in a payment instruction.
Thus, if a customer pays a department store
bill by check, payment occurs when the
check is placed in the hands of the department store, and settlement occurs when the
check clears and the department stores bank
account is credited. If the customer pays the
bill with cash, payment and settlement are
simultaneous.
When two traders enter a deal and agree to
undertake a foreign exchange transaction, they
are agreeing on the terms of a currency exchange
and committing the resources of their respective
institutions to that agreement. But the execution
of that exchangethe settlementdoes not
take place until later.
Executing a foreign exchange transaction
requires two transfers of money value, in
opposite directions, since it involves the
exchange of one national currency for another.
Execution of the transaction engages the
payment and settlement systems of both
nations, and those systems play a key role in the
operations of the foreign exchange market.
Payment systems have evolved and grown
more sophisticated over time. At present, various
forms of payment are legally acceptable in the
United Statespayments can be made, for
example, by cash, check, automated clearinghouse
(a mechanism developed as a substitute for certain
forms of paper payments), and electronic funds
transfer (for large value transfers between banks).
Each of these accepted forms of payment has its
own settlement techniques and arrangements.
By number of transactions, most payments
in the United States are still made with cash
(currency and coin) or checks. However, the
electronic funds transfer systems, which
account for less than 0.1 percent of the
number of all payments transactions in
t he United States, account for more than
80 percent of the value of payments. Thus,

PAYMENTS VIA FEDWIRE AND CHIPS
When a payment is executed over Fedwire,
a regional Federal Reserve Bank debits on
its books the account of the sending bank
and credits the account of the receiving
bank, so that there is an immediate transfer
from the sending bank and delivery to the
receiving bank of central bank money
(i.e.,a deposit claim on that Federal Reserve
Bank).A Fedwire payment is settledwhen
the receiving bank has its deposit account at
the Fed credited with the funds or is
notified of the payment. Fedwire is a realtime gross settlements (or RTGS) system.
To control risk on Fedwire, the Federal
Reserve imposes charges on participants
for intra-day (daylight) overdrafts beyond a
permissible allowance.
In contrast to Fedwire, payments
processed over CHIPS are finally settled,
not individually during the course of the day,
but collectively at the end of the business day,
after the net debit or credit position of each
CHIPS participant (against all other CHIPS
participants) has been determined. Final
settlement of CHIPS obligations occurs by
Fedwire transfer (delivery of central bank
money). Settlement is initiated when those
CHIPS participants in a net debit position
for the days CHIPS activity pay their days
obligations. If a commercial bank that is
scheduled to receive CHIPS payments makes
funds available to its customers before
CHIPS settlement occurs at the end of the
day, that commercial bank is exposed to
some risk of loss if CHIPS settlement cannot
occur.To ensure that settlement does, in fact,
occur, the New York Clearing House has put
in place a system of net debit caps and a losssharing arrangement backed up by collateral
as a risk control mechanism.
electronic funds transfer systems represent
a key and indispensable component of the
payment and settlement systems. It is the
electronic funds transfer systems that execute
the inter-bank transfers between dealers
in the foreign exchange market. The two
electronic funds transfer systems operating in
the United States are CHIPS (Clearing House
Interbank Payments System), a privately
owned system run by the New York Clearing
House, and Fedwire, a system run by the
Federal Reserve (see Box 2-2).
Other countries also have large-value
interbank funds transfer systems, similar to
Fedwire and CHIPS in the United States. In the
United Kingdom, the pound sterling leg of a
foreign exchange transaction is likely to be
settled through CHAPSthe Clearing House
Association Payments System, an RTGS
system whose member banks settle with each
other through their accounts at the Bank of
England. In Germany, the Deutsche mark leg of
a transaction is settled through EAFan
electronic payments system where settlements
are made through accounts at Germanys
central bank, the Deutsche Bundesbank. A new
payment system, named Target, has been
designed to link RTGS systems within the
European Community, to enable participants to
handle transactions in the euro upon its
introduction on January 1, 1999.
Globally, more than 80 percent of global
foreign exchange transactions have a dollar leg.
Thus, the amount of daily dollar settlements is
huge, one trillion dollars per day or more. The
settlement of foreign exchange transactions
accounts for the bulk of total dollar payments
processed through CHIPS each day.
The matter of settlement practices is of
particular importance to the foreign exchange

market because of settlement risk, the risk that
one party to a foreign exchange transaction will
pay out the currency it is selling but not receive
the currency it is buying. Because of time zone
differences and delays caused by the banks own
internal procedures and corresponding banking
arrangements, a substantial amount of time
can pass between a payment and the time the
counter-payment is receivedand a substantial
credit risk can arise. Efforts to reduce or
eliminate settlement risk are discussed in
Chapter 8.
