Chapter 14: Banks, Money, and the Federal Reserve System

Introduction

This chapter explores the nature and functions of money, how money is measured and created in the United States, the structure and role of the Federal Reserve System, and the relationship between money supply and inflation. Understanding these concepts is essential for analyzing the macroeconomic environment and the stability of the financial system.

What Is Money, and Why Do We Need It?

Definition and Functions of Money

Money is any asset that people are generally willing to accept in exchange for goods and services or for payment of debts. It is a fundamental invention that facilitates trade and economic development.

• Medium of Exchange: Money is widely accepted as payment for goods and services.

• Unit of Account: Money provides a standard measure of value, making it easier to compare prices.

• Store of Value: Money can be saved and used for future purchases; it is highly liquid compared to other assets.

• Standard of Deferred Payment: Money enables transactions to be settled over time, with predictable value.

Barter and the Evolution of Money

Before money, trade required a double coincidence of wants, making transactions inefficient. The introduction of commodity money (items with intrinsic value, such as gold or animal skins) improved trade efficiency and allowed for economic specialization.

Characteristics of Good Money

• Acceptable to most people

• Standardized quality

• Durable

• Valuable relative to weight

• Divisible for various transaction sizes

Commodity Money vs. Fiat Money

• Commodity Money: Has value independent of its use as money (e.g., gold, silver, cowrie shells).

• Fiat Money: Authorized by a central bank or government, not backed by a physical commodity. Its value depends on public confidence.

Advantages of Fiat Money: Flexibility for central banks to manage the money supply. Disadvantages: Relies on public trust; loss of confidence can render it worthless.

Legal Acceptance of Money

Businesses are not required to accept cash for transactions, as illustrated by some establishments moving to cashless payments for efficiency and security.

How Is Money Measured in the United States Today?

Definitions of the Money Supply

• M1: Currency in circulation + checking account deposits + savings account deposits.

• M2: M1 + small-denomination time deposits + noninstitutional money market fund shares.

As of September 2023, M1 was about $18.1 trillion and M2 about $20.8 trillion. U.S. currency holdings are high, partly due to use in other countries and underground economies.

Debit and Credit Cards

• Debit Cards: Access checking accounts directly; the account balance is counted as money, not the card itself.

• Credit Cards: Provide short-term loans; transactions are not complete until the loan is repaid, so credit cards are not considered money.

Digital and Cryptocurrencies

Digital payment systems (e.g., PayPal, Apple Pay) are increasingly trusted. Cryptocurrencies like Bitcoin are decentralized digital assets that can be traded and used for some transactions, but are not currently included in official money supply measures.

How Do Banks Create Money?

The Role of Banks

Banks are profit-seeking firms that accept deposits and make loans, playing a critical role in the creation of money. The majority of money exists as deposits rather than physical currency.

Bank Balance Sheets

• Assets: Loans, securities, reserves (cash in vault or with the Federal Reserve).

• Liabilities: Deposits owed to customers, other borrowings.

Reserves and Fractional Reserve Banking

Banks keep only a fraction of deposits as reserves, lending out the rest. This system is called fractional reserve banking. As of March 2020, the Federal Reserve set the reserve requirement to 0% for checking deposits.

Economic Importance of Bank Lending

• Reduces Transaction Costs: Banks use economies of scale and specialization to lower the costs of lending and borrowing.

• Reduces Information Problems: Banks assess borrower risk using private information and statistical analysis, addressing issues of asymmetric information.

Money Creation Process

When a bank receives a deposit, it keeps a portion as reserves and lends out the rest. The process of lending and redepositing creates new deposits, expanding the money supply through the money multiplier effect.

Money Multiplier Formula:

However, the actual multiplier fluctuates due to changes in reserve holdings and public preferences for cash versus deposits.

The Federal Reserve System

Structure and Functions

• Board of Governors: Seven members appointed for 14-year terms, with a chair serving a 4-year renewable term.

• Federal Open Market Committee (FOMC): Twelve members (Board of Governors + regional bank presidents) responsible for open market operations and managing the money supply.

Role in Financial Stability

The Fed acts as a lender of last resort to prevent bank runs and panics. It also insures deposits through the FDIC (up to $250,000 per account), reducing the risk of widespread bank failures.

Monetary Policy Tools

• Open Market Operations: Buying and selling Treasury securities to influence the money supply.

• Discount Rate: Interest rate charged to banks for short-term loans from the Fed.

• Reserve Requirements: (Currently set to zero for checking deposits.)

Open market purchases increase the monetary base and money supply; sales decrease them. The Fed now focuses more on controlling interest rates than the money supply directly.

Bank Regulation and Moral Hazard

Banks are heavily regulated to ensure stability. The FDIC resolves failed banks to minimize costs and discourage risky behavior (moral hazard). In cases of systemic risk, the FDIC may reimburse all deposits, increasing the risk of future moral hazard.

The Shadow Banking System

Nonbank financial firms (investment banks, money market funds, hedge funds) have become major credit sources. These firms are less regulated and more leveraged, making them vulnerable to financial crises, as seen in 2007–2009.

The Quantity Theory of Money

The Quantity Equation

The relationship between money and prices is formalized by the quantity equation:

• M: Money supply

• V: Velocity of money (average number of times each dollar is used in transactions)

• P: Price level

• Y: Real output (real GDP)

Implications for Inflation

Assuming velocity is constant, the growth rate form of the equation is:

Thus, if the money supply grows faster than real GDP, inflation occurs. If it grows slower, deflation results. In the long run, persistent inflation is caused by rapid money supply growth.

Hyperinflation

Hyperinflation (inflation > 50% per month) occurs when central banks rapidly increase the money supply, often to finance government deficits. Recent examples include Zimbabwe and Venezuela, where prices rose astronomically and economic activity collapsed.
