What is Monetary Policy?
Monetary policy refers to the actions taken by a country’s central bank to manage the money supply, interest rates, and credit conditions in order to achieve economic objectives such as price stability, full employment, and sustainable growth.
Definition
Monetary policy is the process by which a central bank regulates the availability and cost of money and credit in the economy to influence macroeconomic outcomes.
Key Takeaways
- Implemented by central banks (e.g., Federal Reserve, ECB, Bank of Botswana).
- Influences inflation, employment, and economic growth.
- Uses tools such as interest rates, open market operations, and reserve requirements.
Understanding Monetary Policy
Central banks use monetary policy to stabilize the economy and promote long-term growth. When inflation is high, central banks may tighten policy By raising interest rates and reducing money supply. When economic growth is slow, they may adopt expansionary policies to lower interest rates, encourage spending, and increase liquidity.
Monetary policy can be expansionary (to stimulate the economy) or contractionary (to cool down inflation). The transmission mechanism describes how policy changes influence borrowing costs, spending behaviour, asset prices, and overall economic activity.
Formula (If Applicable)
There is no single formula for monetary policy, but several models relate:
- Taylor Rule:
Interest Rate = Neutral Rate + 0.5(Inflation Gap) + 0.5(Output Gap)
Real-World Example
During the COVID-19 pandemic, central banks worldwide lowered interest rates and purchased government bonds to stabilize financial markets and support economic activity.
