Federal Funds Rate – Definition & Examples

Definition: The interest rate at which banks lend reserve balances to other banks overnight.

Detailed Explanation

The fed funds rate is the Fed's primary policy rate—the rate it targets through open market operations. When the Fed wants to stimulate the economy, it lowers this target; to cool things down, it raises the target. This rate influences all other interest rates in the economy (mortgages, business loans, savings).

Real-World Example

The Fed raised the fed funds rate from near 0% to over 5% in 2022-23 to fight inflation. Mortgage rates followed, rising from about 3% to over 7%, cooling the housing market.

AP Economics Relevance

That habit is especially helpful for AP, IB, and introductory college economics.
