The South African Reserve Bank (SARB) is the central bank of South Africa, responsible for managing the country's monetary policy and ensuring financial stability. Established in 1921, it aims to protect the value of the national currency, the South African rand, and oversee the banking system. SARB also plays a crucial role in regulating the financial sector and issuing banknotes. It works to promote economic growth and stability by controlling inflation and managing interest rates, which influence borrowing and spending in the economy.
