This study note for Edexcel economics covers Monetary Policy Instruments
Overview
Monetary policy involves the actions taken by a country's central bank to influence the availability and cost of money and credit to achieve macroeconomic objectives such as controlling inflation, maintaining employment, and achieving economic growth. Key instruments of monetary policy include interest rates, asset purchases (quantitative easing), and intervention in currency markets.
Interest Rates
Definition:
- The interest rate is the cost of borrowing money or the return on savings, set by the central bank to influence economic activity.
Mechanism:
- Lowering Interest Rates: Encourages borrowing and spending by consumers and businesses, stimulating economic growth.
- Raising Interest Rates: Discourages borrowing and spending, aiming to cool down an overheated economy and control inflation.
Example:
- U.S. Federal Reserve (2008-2015): The Fed reduced the federal funds rate to near zero during the Global Financial Crisis to stimulate the economy.
Effectiveness:
- Short-term Impact: Immediate influence on borrowing costs and economic activity.
- Long-term Impact: Influences expectations about future inflation and economic conditions.
Asset Purchases to Increase the Money Supply (Quantitative Easing)
Definition:
- Quantitative easing (QE) is a non-traditional monetary policy tool where the central bank buys financial assets to inject liquidity into the economy.
Mechanism:
- Purchasing Assets: Central banks buy government bonds and other financial assets, increasing the money supply and lowering interest rates on these assets.
- Encouraging Investment: Lower yields on bonds push investors towards riskier assets like stocks, stimulating economic activity.
Example:
- Bank of England (2009-2012): Implemented QE by purchasing £375 billion of assets to support the UK economy during the financial crisis.
Effectiveness:
- Liquidity Injection: Increases bank reserves, encouraging lending.
- Market Confidence: Signals the central bank's commitment to supporting the economy.
Intervention in Currency Markets
Definition:
- Currency market intervention involves the buying or selling of a country’s currency by its central bank to influence the exchange rate.
Mechanism:
- Buying Domestic Currency: Reduces money supply, increasing its value.
- Selling Domestic Currency: Increases money supply, decreasing its value.
Example:
- Swiss National Bank (2011-2015): Intervened to cap the Swiss franc against the euro to protect exports.
Effectiveness:
- Exchange Rate Stability: Helps stabilize the currency, supporting trade and investment.
- Competitive Exports: A weaker domestic currency makes exports cheaper and more competitive globally.
Glossary
- Asset Purchases: The buying of financial assets by a central bank to increase the money supply.
- Currency Market Intervention: Actions by a central bank to influence the value of its currency.
- Exchange Rate: The value of one currency for the purpose of conversion to another.
- Interest Rate: The cost of borrowing money or the return on savings.
- Quantitative Easing (QE): A non-traditional monetary policy tool involving large-scale purchases of financial assets to inject liquidity into the economy.
