Who controls changes in the money supply in the US?

The Federal Reserve Bank is the central authority responsible for controlling changes in the money supply in the United States. It implements monetary policy through various tools, including open market operations, the discount rate, and reserve requirements. By adjusting these levers, the Federal Reserve can influence interest rates and the overall economy, thereby managing inflation and employment levels.

The Federal Reserve operates independently of the federal government in terms of monetary policy, which allows it to make decisions based on economic conditions rather than political pressures. This independence is crucial for maintaining stable economic growth and ensuring that monetary policy is effectively aligned with the nation's economic goals.
