Federal Reserve and Monetary Policy

Introduction

This chapter explores the role of the Federal Reserve in the U.S. economy, focusing on its monetary policy tools, objectives, and the impact of these policies on aggregate demand, real GDP, and the price level. Understanding these concepts is essential for analyzing macroeconomic stability and growth.

15.1 What Is Monetary Policy?

Definition and Objectives

  • Monetary policy: The actions the Federal Reserve (the Fed) takes to manage the money supply and interest rates to pursue macroeconomic policy objectives.

  • The Fed pursues four main monetary policy goals:

    1. Price stability

    2. High employment

    3. Stability of financial markets and institutions

    4. Economic growth

Role of the Federal Reserve

  • Created in 1913 to maintain stability in financial markets and institutions, especially to prevent bank panics.

  • After the Great Depression, Congress mandated the Fed to promote maximum employment, stable prices, and moderate long-term interest rates.

  • Since World War II, the Fed has conducted active monetary policy.

Dual Mandate

  • Full employment

  • Price stability (keeping inflation small)

15.2 The Federal Funds Rate and How the Fed Conducts Monetary Policy

Interest Rates and Aggregate Demand

  • The Fed aims to keep real GDP close to potential GDP by influencing aggregate demand through interest rates.

  • Interest rates most affecting aggregate demand are the real interest rates on mortgage loans, corporate bonds, and U.S. Treasury bonds (long-term rates).

  • The Fed can mostly affect short-term interest rates rather than long-term rates.

Federal Funds Rate

  • The Federal Open Market Committee (FOMC) sets targets for the federal funds rate (the interest rate banks charge each other for overnight loans of excess reserves).

  • Example: In June 2025, the target was 4.25 to 4.50 percent.

Monetary Policy Types

Type

Purpose

Method

Expansionary

Increase growth of aggregate demand, real GDP, and employment

Lower the target for the federal funds rate

Contractionary

Decrease growth of aggregate demand, real GDP, and employment

Raise the target for the federal funds rate

Federal Reserve Tools

Traditional Tools

  • Federal Funds Rate: Rate for overnight bank lending of excess reserves.

  • Discount Rate: Rate charged by the Fed when lending reserves to banks.

  • Open Market Operations: Buying and selling of bonds to maintain equilibrium interest rate.

  • Reserve Requirements: Amount banks must hold in reserve (became zero in March 2020).

Current Tools

  • Interest Rate On Reserve Balances (IORB): Interest paid by the Fed to banks on reserves held at the Fed.

  • Interest Rate on Overnight Reserves Repurchase Agreements (ONRRP): Interest paid on overnight securities bought by the Fed.

  • Quantitative Easing: Fed purchases long-term securities to provide reserves to banks.

  • Forward Guidance: Fed signals its intentions for future federal funds rate changes.

Controlling the Federal Funds Rate

Situation

Name

Method

Banks keep few reserves (required reserve ratio)

Scarce-reserves regime

Adjust the supply of reserves

Banks keep more reserves than required

Ample-reserves regime

Adjust the interest rate on reserve balances (IORB)

Equilibrium in the Federal Funds Market

  • In a scarce-reserves regime, the demand for reserves is downward sloping; the supply is vertical (Fed supplies needed reserves).

  • Equilibrium occurs where the quantity of reserves demanded equals the quantity supplied.

  • In an ample-reserves regime, the supply of reserves is more than needed; the equilibrium rate equals the IORB.

Quantitative Easing and Zero Interest Rates

  • When interest rates approach zero, the Fed uses quantitative easing (purchasing long-term securities) to provide reserves to banks and stimulate the economy.

Summary of the Fed's Monetary Policy Tools

  1. Most important tools:

    • Interest on reserve balances (IORB)

    • Interest rate on overnight reverse repurchase agreements (ONRRP)

  2. Zero lower bound tools:

    • Quantitative easing

    • Forward guidance

  3. Traditional tools:

    • Open market operations

    • Discount rate

    • Reserve requirements

Difference Between Open Market Operations and Quantitative Easing

Feature

Open Market Operations (OMOs)

Quantitative Easing (QE)

Primary Goal

Manage the federal funds rate

Lower long-term interest rates and stimulate the economy

Scale

Relatively small and frequent transactions

Very large-scale asset purchases

Target Assets

Short-term government bonds

Wider variety of assets, including long-term securities

Context/Timing

Routine tool of monetary policy

Unconventional policy, used at zero lower bound

Target Mechanism

Affects supply of bank reserves

Affects price and yield of long-term assets

15.3 Monetary Policy and Economic Activity

Aggregate Demand and Aggregate Supply

  • Monetary policy affects aggregate demand (AD) and aggregate supply (AS), influencing real GDP and the price level.

  • Aggregate demand formula: where = Real GDP = Consumption = Investment = Government spending = Exports = Imports

How Interest Rates Affect Aggregate Demand

  • Consumption: Lower interest rates encourage buying on credit, increasing sales of durable goods.

  • Investment: Lower rates make borrowing cheaper for firms and households, increasing capital investment and residential investment.

  • Net exports: Higher U.S. interest rates attract foreign funds, raising the U.S. exchange rate and causing net exports to fall.

Monetary Policy Responses to Economic Gaps

Recessionary Gap

  • Expansionary monetary policy: The Fed decreases interest rates, increasing consumption, investment, and net exports. Aggregate demand shifts right.

  • Short-run real GDP is below potential, with high unemployment and idle capital.

Inflationary Gap

  • Contractionary monetary policy: The Fed increases interest rates, decreasing consumption, investment, and net exports. Aggregate demand shifts left.

  • Short-run real GDP is above potential, with low unemployment, overuse of capital, and rising price levels (high inflation).

Open Market Operations: Effects on the Economy

Selling Bonds (Contractionary Policy)

  • Fed sells bonds, receives cash, decreases money supply, increases interest rates, and decreases investment.

  • Results: Lower investment, lower employment, lower real GDP.

Buying Bonds (Expansionary Policy)

  • Fed buys bonds, injects cash, increases money supply, decreases interest rates, and increases investment.

  • Results: Higher prices (inflation), higher employment, higher real GDP.

Lags in Monetary Policy

  • Recognition Lag: Delay between a macroeconomic problem arising and policymakers becoming aware of it.

  • Implementation Lag: Delay between recognizing a problem and enacting a policy response.

  • Impact Lag: Delay between enacting a policy and its effect on the economy.

Practice and Application

Analyzing Federal Reserve Policy Statements

  • Use FRED (Federal Reserve Economic Data) to track changes in the federal funds rate.

  • Review FOMC policy statements to understand the economic conditions and policy tools used.

  • Draw the impact of monetary policy changes on AD-AS graphs.

Example: Policy Changes

  • Rate hikes (tightening policy) and rate cuts (easing policy) are associated with different macroeconomic conditions (growth, inflation, unemployment).

Key Terms and Concepts
