A financial institution with exclusive authority over the creation and distribution of money and credit for a country or a group of countries is known as the central bank. In contemporary economies, the central bank is typically in charge of monetary policy formulation and member bank regulation. Inherently non-market-based or even anti-competitive institutions are central banks. Many central banks, despite the fact that some have been nationalized, are not part of the government and are therefore frequently hailed as being politically independent.
