What Are Banks?
Commercial Banks: Principal activity: receives deposits and makes loans. Investment banks (US): Purchaser or underwriter of large blocks of securities, reseller of them. The word bank is misleading, since according to the Glass Steagall Act 1933 they could not accept deposits. Central Banks
Other Depository Institutions
Savings Banks: The savings bank movement began in the UK early 19th century to help relieve penury. Eleemosynary. Survivors from long ago. Saving and Loan Associations (from building society movement UK) Movement that created them emphasized pooling resources to buy homes. Credit Unions: Cooperative organizations that accept deposits and make loans to members.
Adverse Selection Problem with Securities Solved by Banks
Adverse selection: Issuers of securities have trouble getting a good price for them, since the market as a whole cannot distinguish good from bad companies. So, only the bad companies are willing to issue securities. The market for securities can break down, owners cant sell them. Public good nature of information: No one will take trouble to collect information about companies and give it away, cant sell it for a high price either since others will give it away.
Moral Hazard Problem with Securities Solved by Banks
Managers or stockholders in a firm have an incentive to take big risks unseen by the bondholders. If bondholders are dispersed, none of them is willing to spend the time to monitor the firm, and none has ability to control management. Banks more prominent in economies of less developed countries because information asymmetry is more of a problem there.
Banks Generate Liquidity
Because of adverse selection and moral hazard problems, firms often tend to be closely held by people connected to them and knowledgeable about them. But such holdings are inherently illiquid. Banks come to the rescue. Banks create liquidity accepting by short-term deposits and making short-term (effectively long term) business loans. Monitor the loans, threaten to call them. Banks specialize in intimate knowledge of businesses in their own community, fostered by their continuing connection with them.
U.S. S&L Crisis early 1980s
Depository Institutions Deregulation and Monetary Control Act 1980 phased out deposit rate ceilings Ronald Reagan belief in free markets loosened regulation, but forgot to cancel their insurance Regulators lax in the past had no incentive to reveal their own past mistakes: they kept quiet and hoped that good fortune would prevent their errors from creating a banking crisis.
Mexican Crisis 1994-5
Crisis was preceded by privatization of large Mexican banks in early 1990s. Mexican government did not rapidly establish good regulation Bank lending boom: loans rose from 10% of GDP in 1988 to 40% by 1994 Banks thought Mexican government would likely bail them out in trouble. Bad loans extended in a carefree way. Colosio assassination, 1994, and rise in US interest rates led to collapse of peso
Asian Crisis 1997-8

Risk-Based Capital Requirements
Basel Accord 1988 created framework for capital requirements, G-10 countries US Fed created risk based capital requirements, 1989 Defines Tier 1 capital (core capital) as stockholders equity plus preferred stock (and other items) Defines Tier 2 capital (supplementary capital)
Basel Capital Requirements
Four credit risk categories defined, each asset assigned to a class Weights are assigned to the categories, 0%, 20%, 50% and 100% to define riskweighted assets Tier 1 capital must be 4% of book value Tier 1 + tier 2 capital must be 8% of riskweighted assets
Basel II
Propose that the weights should in the future depend on the riskiness of the borrowers, not just the class of borrowers. Three pillars: minimum capital requirements based on risk-based weighting system, review of capital coverage by national regulators, and disclosure obligations Signing mid 2004, to come into force December 31, 2006, live date for USA extended to January 2009
