The Federal Reserve's Impact on Business Activity and Market Stability

The Federal Reserve is the starting point for understanding economic factors because its decisions on monetary policy set off chain reactions across every financial market.


The Federal Reserve: America's Central Bank

  • The Federal Reserve (the Fed) is the central bank of the United States
  • Its mandate (set by Congress) has three goals:
    • Maximum employment
    • Stable prices (controlling inflation)
    • Moderate long-term interest rates
  • The Fed achieves these goals through monetary policy: controlling the money supply and interest rates

Monetary Policy vs. Fiscal Policy

This is one of the most commonly tested distinctions on the SIE. Both affect the economy, but they come from different places and use different tools.

FeatureMonetary PolicyFiscal Policy
Controlled byThe Federal ReserveCongress and the President
ToolsInterest rates, open market operations, reserve requirementsGovernment spending and taxation
GoalPrice stability, employment, moderate interest ratesEconomic growth, public services, deficit management
SpeedFaster; the Fed can act quicklySlower; requires the legislative process

Exam Tip: Gotchas

  • Monetary policy = the Fed. Fiscal policy = Congress. If the question mentions tax changes or government spending, it is fiscal policy, even if the economic effect sounds similar to monetary policy.

Federal Reserve Tools

The Fed has three primary tools to influence the economy. Think of them as levers that either inject money into the economy (expansionary/easing) or pull money out (contractionary/tightening).

1. Open Market Operations (Most Frequently Used)

  • Conducted by the Federal Open Market Committee (FOMC)
  • The Fed buys or sells securities (typically Treasury bonds) in the open market
ActionEffect on Money SupplyPolicy Type
Buying securitiesInjects money into the economy (bank reserves increase)Expansionary (easing)
Selling securitiesPulls money out of the economy (bank reserves decrease)Contractionary (tightening)
  • This is the Fed's most commonly used and most flexible tool
  • When the Fed buys bonds, it pays cash to sellers, increasing reserves in the banking system
  • When the Fed sells bonds, it absorbs cash from buyers, reducing reserves

Think of it this way: When the Fed buys bonds, it is pumping cash into the economy like turning on a faucet. When it sells bonds, it is draining cash out. More cash in circulation means lower interest rates; less cash means higher rates.

2. Reserve Requirements

  • The percentage of customer deposits that banks must hold in reserve (not lend out)
  • Raising the reserve requirement = contractionary (banks can lend less)
  • Lowering the reserve requirement = expansionary (banks can lend more)
  • This tool is used less frequently because even small changes have large effects

3. Setting Key Interest Rates

The Fed influences several benchmark interest rates. Understanding which rates are set by whom is frequently tested.

RateDefinitionSet By
Federal funds rateThe rate banks charge each other for overnight loans of reservesMarket-driven, but the Fed sets a target range
Discount rateThe rate the Fed charges banks for short-term loans directly from the FedThe Federal Reserve (directly)
Prime rateThe rate banks charge their most creditworthy customersCommercial banks (typically fed funds rate + 3%)

Key relationships:

  • The federal funds rate is the most important benchmark; changes ripple through the entire economy
  • The discount rate is typically higher than the federal funds rate (borrowing from the Fed is a last resort for banks)
  • The prime rate floats above the federal funds rate and is used as a base for consumer and business loans

Exam Tip: Gotchas

  • The Fed does NOT directly set the federal funds rate. It sets a target range. The actual rate is determined by supply and demand in the overnight lending market between banks.
  • The discount rate IS directly set by the Fed. Banks borrow from the Fed at this rate as a last resort.

How Fed Actions Affect Markets

Every Fed action creates a chain reaction across asset classes. This table summarizes the key relationships:

Fed ActionInterest RatesBond PricesStock Prices (generally)Dollar Value
Buys securities (easing)DecreaseIncreaseIncreaseDecrease
Sells securities (tightening)IncreaseDecreaseDecreaseIncrease
Raises discount rateIncreaseDecreaseDecreaseIncrease
Lowers discount rateDecreaseIncreaseIncreaseDecrease

The core relationship to remember:

  • Interest rates and bond prices move in opposite directions (inverse relationship)
  • When rates rise, borrowing becomes more expensive, slowing economic activity
  • When rates fall, borrowing becomes cheaper, stimulating economic activity
  • A tightening Fed strengthens the dollar (higher rates attract foreign investment)
  • An easing Fed weakens the dollar (lower rates make dollar-denominated assets less attractive)

Exam Tip: Gotchas

  • Bond prices and interest rates are INVERSELY related. They never move in the same direction. If rates go up, bond prices go down, and vice versa.
  • A tightening Fed strengthens the dollar. Higher U.S. rates attract foreign investment, increasing demand for dollars.
