Why do central banks?

Central banks play a crucial role in managing a country's monetary policy, which includes controlling inflation, stabilizing the currency, and ensuring economic growth. They regulate the money supply and interest rates to promote financial stability and mitigate economic fluctuations. Additionally, central banks serve as a lender of last resort to financial institutions during times of crisis, helping to maintain confidence in the financial system. Overall, their actions aim to foster a stable economic environment conducive to sustainable growth.
