The reserve requirement, open market operations, and the discount rate are all tools used by the Federal Reserve (Fed) to enact monetary policy. These tools are used to influence the money supply and interest rates in an effort to stabilize the economy, control inflation, and achieve other macroeconomic goals. These tools do not directly protect bank depositors, manipulate the dollar price of gold, or ensure that the value of one dollar is the same in different cities. The Fed is primarily responsible for monetary policy, while fiscal policy is the responsibility of Congress and the President.
