Central Bank
The public institution responsible for a currency's monetary policy, issuance and financial stability.
What Central Bank means
A central bank is the institution that issues a nation's or currency union's money and conducts its monetary policy. Typical responsibilities include setting a policy interest rate, managing the supply of bank reserves, holding foreign exchange reserves, acting as lender of last resort to the banking system, and in many jurisdictions supervising banks and overseeing payment systems. Most modern central banks operate with a legally defined mandate, usually centred on price stability and sometimes extended to employment or financial stability, and with a degree of operational independence from the government.
Central banks dominate foreign exchange because they control the return on holding a currency. Decisions, meeting minutes, projections and speeches all shift the expected path of rates, and it is that expected path rather than the current setting that prices into spot. Balance sheet tools such as asset purchases, reserve requirements and lending facilities matter too, and some authorities intervene directly in the currency market. The practical caveat is that central bank communication is deliberately conditional: guidance describes a reaction to incoming data, so guidance changes when the data changes.
Worked example
If a central bank holds its policy rate unchanged but its statement drops a reference to further tightening, the currency can fall sharply even with no rate change at all, because the expected path has been lowered. Hypothetical illustration.
