🏦 What is Monetary Policy?
The monetary policy is the set of decisions and actions taken by a central bank (such as the European Central Bank or the Federal Reserve) to control the amount of money and the cost of credit in an economy.
Its main goal is to maintain price stability 🏷️ and to promote sustainable economic growth 📈.
💡 What is the purpose of monetary policy?
The essential purpose of monetary policy is to maintain economic balance.
This means:
✅ Avoiding excessively high inflation (when prices rise too fast).
✅ Avoiding deflation (when prices constantly fall).
✅ Boosting employment and investment.
✅ Maintaining financial system stability.
In short: the central bank acts as the economy’s “thermometer” 🩺, regulating the money supply so that the system neither overheats nor cools down.
⚙️ Types of monetary policy
There are two main types of monetary policy, depending on the current economic objectives:
🟢 Expansionary monetary policy
👉 Goal: stimulate the economy.
It is applied during recessions or periods of slow growth.
Typical measures:
- Lowering interest rates 💶
- Increasing the money supply 💵
- Making credit more accessible to businesses and families 🏠
Effect: it increases consumption and investment, but may also raise inflation if maintained for too long.
🔴 Restrictive monetary policy
👉 Goal: curb inflation or excessive spending.
It is applied when the economy grows too fast or when there are inflationary pressures.
Typical measures:
- Raising interest rates 📈
- Reducing the amount of money in circulation 💰
- Selling government bonds or financial assets 📄
Effect: it moderates consumption and investment, keeping prices under control, but it can slow growth.
🧩 Instruments of Monetary Policy
The central bank has several key tools to influence the economy:
💵 1. Official Interest Rate
This is the price of money.
When the central bank raises or lowers interest rates, it directly affects loans and credit.
- Low rates ➡️ more loans ➡️ more spending and investment.
- High rates ➡️ fewer loans ➡️ less spending and consumption.
🏛️ 2. Open Market Operations
This involves buying or selling government bonds.
- If it buys bonds ➡️ injects money into the economy (expansive).
- If it sells bonds ➡️ withdraws money (restrictive).
🏦 3. Reserve Requirement Ratio
This is the percentage of money that banks must keep “in reserve” and cannot lend out.
- If reduced ➡️ banks can lend more.
- If increased ➡️ credit is restricted.
🌍 Practical Example
Imagine there is a strong rise in prices (inflation) 📈.
The European Central Bank could:
- Raise interest rates to make borrowing more expensive.
- Reduce the amount of money in circulation.
- Cool down consumption and investment.
Result: prices stop rising so quickly, and inflation slows down.
On the other hand, if the economy enters a recession, the central bank could lower rates to stimulate spending and investment.
💶 Monetary Policy in the Eurozone
In Europe, monetary policy is managed by the European Central Bank (ECB) 🏛️, whose main objective is:
“To maintain price stability and support the general economic policies of the European Union.”
Its decisions directly affect all eurozone countries 🇪🇺, as they share a common currency: the euro (€).
