Central Banks
Central banks manage money supply and interest rates.
About this topic
A central bank, such as the Federal Reserve in the US, the European Central Bank, the Bank of England or the Reserve Bank of India, manages a country's money supply and interest rates to keep prices stable and support employment. Tools include the policy interest rate, where raising it cools the economy and cutting it stimulates; open market operations, buying or selling government bonds; and reserve requirements.
Central banks matter because stable prices and steady growth help everyone plan, save and invest. They also act as lender of last resort to banks in crisis and supervise the financial system. Most are independent of politicians so that short-term politics does not drive decisions.
Example: if inflation is rising above the 2 percent target, the bank raises its rate. Loans and mortgages become dearer, people spend less, and price pressure eases. In a recession it does the reverse. After the 2008 crisis and in 2020, central banks also used quantitative easing, creating money to buy bonds and lower long-term rates.
Misconceptions: central banks do not simply print money for the government to spend, and they cannot control everything; effects take months and unwanted side effects occur. Tip: higher interest rates mean slower borrowing, lower inflation and weaker growth.
