Central Bank
A central bank manages monetary policy and supports the stability of a country or currency area’s financial system.
Full explanation
A central bank is a public institution responsible for monetary policy, which includes decisions affecting interest rates and the supply of money. It may also issue currency, hold foreign-exchange reserves, supervise parts of the banking system and provide emergency liquidity.
Central bank decisions and communications can influence exchange rates by changing expectations for interest rates, inflation and economic conditions. Important examples include the Bank of England, the European Central Bank and the US Federal Reserve. Policy statements, meeting minutes and officials’ speeches are closely followed in forex markets.
Example: A Bank of England rate decision may cause movement in GBP/USD as the market compares the announcement and policy statement with prior expectations.
Why traders watch it
Changes in monetary policy expectations can affect currency demand, bond yields, volatility and exchange rates.
Trading considerations
- Interest-rate decisions are usually announced on scheduled dates shown in an economic calendar.
- Policy statements and speeches can influence markets even when interest rates remain unchanged.
