Simple Definition

The interest rate banks charge each other to borrow reserves overnight. The Fed sets a target for it.

Why It Matters

The federal funds rate is the anchor for short-term interest rates across the economy. When the Fed changes its target, the cost of borrowing ripples outward into savings rates, credit cards, business loans, and eventually mortgage and bond markets. It is the single number most associated with "the Fed raised (or cut) rates."

Key Points

  • Set as a target range (for example, 5.25%–5.50%), not a single fixed number
  • Decided by the FOMC across its eight scheduled meetings a year
  • Changes are usually measured in basis points (25 bps = 0.25%)
