Monetary policy refers to actions undertaken by a central bank to manipulate the money supply and credit conditions to stimulate or restrain economic activity.
It’s a key tool used to influence inflation, employment, and overall economic growth.
Key Characteristics / Core Concepts
- Interest Rates: The central bank influences borrowing costs by adjusting interest rates (e.g., the federal funds rate in the US).
- Reserve Requirements: Banks are required to hold a certain percentage of deposits as reserves; altering this requirement impacts lending capacity.
- Open Market Operations: The central bank buys or sells government securities to increase or decrease the money supply.
- Inflation Targeting: Many central banks aim to maintain inflation within a specific target range.
- Quantitative Easing (QE): Involves large-scale asset purchases (usually government bonds) to inject liquidity into the market (often used during economic crises).
How It Works / Its Function
Monetary policy works by influencing the cost and availability of credit. Lowering interest rates encourages borrowing and investment, stimulating economic activity. Conversely, raising rates discourages borrowing and slows down the economy.
The central bank aims to strike a balance between controlling inflation and promoting sustainable economic growth.
Examples
- Lowering Interest Rates during a Recession: To boost economic activity and create jobs.
- Raising Interest Rates during Inflation: To cool down an overheating economy and curb rising prices.
- Quantitative Easing (QE): Implemented by several central banks after the 2008 financial crisis to increase liquidity.
Why is it Important? / Significance
Effective monetary policy is crucial for maintaining price stability, full employment, and sustainable economic growth. It acts as a stabilizer during economic booms and busts.
Without sound monetary policy, economies can experience severe inflation, recessions, or financial instability.
