Central bank
A financial institution managing monetary policy and ensuring banking stability.
A central bank, also known as a reserve bank, national bank, state bank, or monetary authority, is a financial institution that manages the monetary policy of a country or monetary union. Unlike commercial banks, a central bank holds a monopoly on increasing the monetary base and often has supervisory or regulatory powers to ensure commercial bank stability, prevent bank runs, and enforce policies on financial consumer protection, anti-fraud, anti-money laundering, or counter-terrorism financing. Central banks are crucial for macroeconomic forecasting, especially during economic turbulence, and in most developed nations are institutionally independent from political interference, though governments typically have governance rights and legislative bodies exercise scrutiny.

Lore & Background
The notion of central banks as a separate category emerged gradually and coalesced in the 20th century.

Reader's Guide
Central banks are significant because they manage monetary policy, control the monetary base, and ensure financial stability through supervision and regulation. Their role in macroeconomic forecasting is essential for guiding policy, especially during economic turbulence. The widespread adoption of central banking is recent: at the start of the 20th century, about two-thirds of sovereign states lacked a central bank. Waves of adoption occurred in the interwar period and after World War II, often to attract foreign capital, as bankers preferred lending to countries with a central bank on the gold standard. Central banks in most developed nations are institutionally independent from political interference, though they remain subject to government governance and legislative scrutiny. Issues such as central bank independence, policies, and governors' rhetoric are points of contention among policymakers, researchers, and specialized media. The legacy of central banks includes their evolution from municipal public banks in the 15th century to modern institutions that shape national and global economies.
