Fractional reserve banking is a system in which banks are required to hold only a fraction of their deposits as reserves. This means that banks can lend out the majority of the money they receive as deposits, which leads to an increase in the money supply.

Central banks, such as the Federal Reserve in the United States, are responsible for regulating the money supply and implementing monetary policy. Monetary policy is the process by which a central bank manages the money supply and interest rates in an economy. Central banks use tools such as open market operations, discount rate, and reserve requirements to control the money supply and stabilize the economy.
