A central bank is an independent institution that has the primary responsibility for a country's monetary policy. Other responsibilities of the central bank include the implementation of specific objectives such as reasonable inflation, currency stability and full employment. In addition, central banks act as supervisory authorities and monitor the activities of commercial banks in a country, issue regulatory orders, circulate money and act as the bank of the government of a country. Central banks play an important role in the forex market because they influence the exchange rate of the domestic currency through their policies. They often have a target exchange rate that the bank tries to maintain, for example, through market intervention or changes in interest rates.
