U.S. Banking & Monetary Policy: Key Concepts and Institutions

U.S. Banking & Monetary Policy

Overview

This study guide covers foundational topics in U.S. banking and monetary policy, including the functions of money, types of financial institutions, the measurement and creation of money, and the role of the Federal Reserve. These concepts are essential for understanding macroeconomic systems and policy decisions.

Medium of Exchange

Historical Development and Functions

The medium of exchange is a fundamental function of money, enabling efficient trade and economic activity.

• Need for Money: Money arose to avoid the inefficiencies of bartering and the risks of carrying coinage.

• Barter System: Bartering became inefficient as economies grew and transactions became more complex.

• Early Banking Practices: Notes were exchanged for cash in other cities to avoid robberies and facilitate trade (e.g., London Royal Exchange in the 1500s).

• Financial Institutions: Early bankers, city exchanges, and pawn shops (Lombard’s) played roles in the development of money as a medium of exchange.

Example: Merchants in medieval Europe used bills of exchange to transfer money safely between cities.

Other Money Uses

Functions Beyond Exchange

Money serves several key functions in the economy beyond acting as a medium of exchange.

• Measure of Value: Money provides consistency and universality in valuing goods and services.

• Store of Value: Money can be held for future use, maintaining its value over time and allowing productive use while holding.

• Means of Deferred Payment: Money facilitates borrowing and lending, making it easier to repay loans, though there is a slight risk in valuation changes due to inflation or other factors.

Example: Savings accounts allow individuals to store value and earn interest over time.

Money Terms

Key Definitions

Understanding the terminology associated with money is crucial for analyzing monetary systems.

• Currency: Coins and paper notes created to facilitate the trade of goods/services and payment of debts.

• Legal Tender: Currency officially declared by the government to be accepted for payment of debts.

• Fiat Money: Money established by government declaration, not backed by a physical commodity.

• Liquidity: The ease with which an asset can be converted into cash without loss of value.

Example: U.S. dollars are fiat money and legal tender, accepted for all debts, public and private.

Backing of Money

Why Money is Accepted

The acceptance of currency depends on trust, legal frameworks, and historical standards.

• Gresham’s Law: "Bad money drives out good"—inferior currency tends to circulate more than superior currency.

• Commodity Standards: U.S. Silver Standard (1875), U.S. Gold Standard (1901-32), International Gold Standard (1946-71).

• Modern Backing: Today, U.S. currency is backed by the "full faith and credit" of the U.S. government rather than precious metals.

Example: The transition from gold-backed dollars to fiat currency in the 20th century.

Basic Definitions

Financial Activities

Key financial activities include saving, lending, and underwriting, each with distinct roles in the economy.

• Saving: Intentionally setting aside money for future use, typically earning little or no interest.

• Lending: Providing money for a borrower's use, often with an interest rate as payment for the service.

• Underwriting: Detailed analysis of a borrower's creditworthiness, needs, and ability to repay a loan.

Example: Banks underwrite loans to assess risk before lending to individuals or businesses.

Depository Institutions

Types and Functions

Depository institutions are organizations that accept deposits and ensure funds are available for withdrawal.

• Commercial Bank: A business that exists to earn profit for its owners by accepting deposits and making loans.

• Credit Union: A cooperative owned and operated by its members, managed by a volunteer board of directors.

• Savings & Loans: A cooperative or publicly traded institution that extends services to both members and non-members.

Example: Wells Fargo is a commercial bank, while Navy Federal is a credit union.

Measuring Money

Components and Ratios

The money supply is measured using various components and regulatory ratios.

• Demand Deposits: Bank account balances that can be accessed on demand, such as checking and savings accounts.

• Transaction Deposits: Deposits easily converted to currency, including traveler’s checks.

• Required Reserve Ratio: The percentage of deposits that banks must hold at the Federal Reserve or in their vaults.

Example: If the required reserve ratio is 10%, a bank must keep $10 in reserves for every $100 in deposits.

Creating Money

Banking System and Money Multiplier

Banks create money through lending and deposit activities, governed by reserve requirements and the money multiplier effect.

• Checkable Deposits: Banks solicit deposits that can be withdrawn by writing checks.

• Interest Rate Spread: Banks charge higher interest rates for loans than they pay on deposits, earning profit.

• Balance Sheet: Assets = Liabilities + Equity; excess reserves represent funds available for lending.

• Money Multiplier: Measures the potential amount of money the banking system can generate with each dollar of reserves.

Formula:

$\text{Money Multiplier} = \frac{1}{\text{Required Reserve Ratio}}$

Example: With a required reserve ratio of 10%, the money multiplier is $\frac{1}{0.10} = 10$.

Fractional Reserve Banking

System and Effects

Fractional reserve banking allows banks to lend out a portion of deposits, increasing the money supply through the multiplier effect.

• Excess Reserves: Funds held by banks above the required minimum, available for lending.

• Money Creation: Each loan made by a bank creates new deposits, expanding the money supply.

Formula:

$\text{Total Money Created} = \text{Initial Deposit} \times \text{Money Multiplier}$

Example: An initial deposit of $1,000 with a multiplier of 10 creates $10,000 in total money.

Challenges in Banking

Historical Crises and Responses

The banking system has faced significant challenges, including economic crises and policy responses.

• Great Depression: Led to widespread bank failures and loss of public confidence.

• Savings and Loan Crisis (1980s): High loan defaults and consumer demand for deposits drained bank and insurance funds.

• Credit Crises: Recent events include TARP, QE, politicization of the Federal Reserve, and inflation concerns.

Example: The 2008 financial crisis prompted government intervention through programs like TARP and quantitative easing (QE).

Overcoming Challenges

Government Policy and Stability

Government policies aim to stabilize the banking system and prevent future crises.

• Fiscal Policy: Government spending and taxation to influence the economy.

• Monetary Policy: Central bank actions to control the money supply and interest rates.

• Federal Deposit Insurance Corporation (FDIC): Insures deposits and eliminates 'runs on the bank,' promoting stability.

Example: FDIC insurance guarantees deposits up to a certain limit, reducing panic during economic downturns.

U.S. Federal Reserve

Structure and Functions

The Federal Reserve is the central bank of the United States, responsible for monetary policy and financial stability.

• Federal Reserve System: Established in 1913, consists of 12 regional branches and is governed by the Board of Governors.

• Federal Open Market Committee (FOMC): Sets monetary policy, relatively independent from the President, Treasury, and Congress.

• Central Bank Functions: Maintains reserve requirements, acts as lender of last resort, provides services to commercial banks, and completes international transactions.

Example: The FOMC adjusts the federal funds rate to influence economic activity.

Monetary Policy

Tools and Operations

Monetary policy involves various tools used by the Federal Reserve to manage the money supply and interest rates.

• Securities Transactions: Buying and selling government securities to influence the money supply.

• Federal Funds Rate: The interest rate at which banks lend reserves to each other overnight.

• Discount Rate: The interest rate charged by the Federal Reserve to commercial banks for short-term loans.

• Reserve Requirements: Regulations on the minimum reserves banks must hold.

• Foreign Currency Operations: Managing exchange rates and international financial stability.

Formula:

$\text{Federal Funds Rate}$

Example: Lowering the federal funds rate can stimulate borrowing and investment, boosting economic growth.
