Who uses monetary policy?

Monetary policy is primarily used by a nation's central bank, such as the Federal Reserve in the United States or the European Central Bank in the Eurozone. These institutions adjust interest rates, control money supply, and implement other financial measures to influence economic activity, manage inflation, and stabilize the currency. Government policymakers may also rely on central bank actions to guide fiscal policy decisions and overall economic strategy. Ultimately, the goal is to promote sustainable economic growth and maintain price stability.
