At the heart of monetarism is the concept of money supply, which refers to the total amount of money circulating within an economy. Monetarists believe that controlling the growth of the money supply is crucial for maintaining price stability and overall economic health. The central bank plays a vital role here, using tools such as open market operations, reserve requirements, and interest rate adjustments to influence the amount of money in the economy.
- Open Market Operations: Buying and selling government securities to expand or contract the amount of money in the banking system.
- Reserve Requirements: Adjusting the minimum reserves each bank must hold to ensure they can meet the demand for withdrawals.
- Interest Rates: Changing the rates at which banks can borrow money, thus influencing borrowing and spending in the economy.
Monetarists argue that excessive growth in money supply leads to inflation, hence the central bank must aim to align money supply growth with real economic growth.
