Central Bank

A central bank is the major regulatory bank in a nation or group of nations' monetary system. Its role normally includes control of the credit system, the issuing of notes and coins and supervision of commercial banks. It also manages its country's foreign exchange reserves and acts as its government's banker. Central banks in developed economies are also responsible for the conduct of monetary policy.
