What is monetary policy?
Monetary policy is how a central bank influences interest rates and financial conditions to pursue economic objectives. In the United States, Congress directs the Federal Reserve to promote maximum employment, stable prices, and moderate long-term interest rates. The Fed's own monetary policy explainer describes how its decisions pass through to households and businesses.
Monetary policy tools
| Tool | How it affects conditions |
|---|---|
| Policy rate | Changes the anchor for short-term borrowing costs |
| Balance sheet | Asset purchases can ease longer-term conditions; runoff can tighten them |
| Forward guidance | Shapes expectations for future rates and financial conditions today |
| Liquidity facilities | Support market functioning during periods of stress |
Expansionary versus contractionary policy
Expansionary, or easing, policy lowers borrowing costs or adds liquidity to support demand and employment. Contractionary, or tightening, policy raises borrowing costs or removes liquidity to restrain inflation. Neither label guarantees a market outcome: investors also care about why policy changed and what was already priced in.
How monetary policy reaches the economy
A policy-rate change first affects money-market rates and expectations. Those shifts flow into bond yields, mortgage rates, business financing, exchange rates, asset prices, and credit availability. Households and companies then adjust spending, hiring, and investment. Because the chain takes time and its strength varies, central banks must make decisions under uncertainty.
Monetary policy versus fiscal policy
Monetary policy is conducted by the central bank. Fiscal policy is government taxation and spending set by elected officials. Both influence demand and inflation, but they use different institutions and tools.
Example
Loosening monetary policy through rate cuts tends to lift stocks and bonds by making money cheaper and more plentiful.
