Monetary Policy

Monetary policy refers to actions taken by a country’s central bank to control the money supply and achieve macroeconomic goals including sustainable economic growth, price stability, and full employment. Central banks use three main tools: open market operations (buying/selling government securities), setting reserve requirements for banks, and adjusting the discount rate (interest rate for bank borrowing from the central bank). For example, during the 2008 crisis, the Federal Reserve lowered rates to near zero and implemented quantitative easing, purchasing trillions in bonds to inject liquidity. Expansionary monetary policy (lower rates, increased money supply) stimulates growth during recessions, while contractionary policy (higher rates, reduced money supply) combats inflation. The Federal Reserve’s dual mandate targets 2% inflation and maximum employment. Monetary policy affects exchange rates, asset prices, and credit availability throughout the economy. Implementation lags can range from 6-18 months.
