Monetary policy is the use by the government or central bank of interest rates or controls on the money supply to influence the economy. The target of monetary policy may be the achievement of a desired level or rate of growth in real activity, the price level, the exchange rate, or the balance of payments.
Historical Context
Monetary policy as a formal practice began in the 20th century, although concepts of controlling money supply can be traced back to the 18th and 19th centuries with the establishment of central banking institutions such as the Bank of England. Modern monetary policy gained prominence post-World War II, especially with the establishment of the Federal Reserve System in the United States.
Types/Categories
Expansionary Monetary Policy
This policy aims to increase the money supply to stimulate economic growth. This often involves lowering interest rates and purchasing government securities.
Contractionary Monetary Policy
This policy aims to decrease the money supply to control inflation. This often involves raising interest rates and selling government securities.
Key Events
- 1971: Nixon Shock - End of the Bretton Woods System.
- 2008: Global Financial Crisis - Major intervention by central banks worldwide.
- 2020: COVID-19 Pandemic - Massive monetary stimulus to support economies.
Detailed Explanations
Methods of Monetary Policy
- Interest Rates: Setting the interest rate charged by the central bank (e.g., Federal Reserve’s Federal Funds Rate).
- Open Market Operations: Sales or purchases of government securities.
- Reserve Requirements: Changes in the required reserve ratios of banks and other financial institutions.
Mechanisms and Effects
Monetary policy works through the effects of the cost and availability of loans on real activity, inflation, and international capital movements, thus impacting the exchange rate. Central bank announcements can also influence market expectations and behaviors.
Mathematical Models/Formulas
- Taylor Rule: \( i_t = r_t + \pi_t + \alpha(\pi_t - \pi^) + \beta(y_t - y^) \)
- \(i_t\): nominal interest rate
- \(r_t\): real interest rate
- \( \pi_t \): current inflation
- \( \pi^* \): target inflation
- \( y_t \): log of real GDP
- \( y^* \): log of potential output
