Central Bank Rate Changes
Key Insight: Central banks use interest rate changes as their primary tool to manage inflation, employment, and economic stability. A single rate decision can ripple through all financial markets.
What is the Federal Funds Rate?
The federal funds rate is the interest rate at which banks lend reserve balances to each other overnight. The Federal Reserve doesn't set this rate directly but influences it through open market operations and sets a target range.
Why Central Banks Change Rates

- • Combat high inflation
- • Cool an overheating economy
- • Strengthen the currency
- • Prevent asset bubbles
Rate Decreases (Dovish)
Used to:
- • Stimulate economic growth
- • Combat unemployment
- • Encourage borrowing/spending
- • Support during recessions
Typical Rate Change Amounts

|---|---|---|
| Standard | 25 bps (0.25%) | Normal, measured adjustment |
| Double | 50 bps (0.50%) | More aggressive action needed |
| Large | 75 bps (0.75%) | Urgent response to conditions |
