What Are Central Banks?
Central banks are national institutions responsible for managing a country’s monetary policy. Their decisions directly influence interest rates, money supply, and overall financial stability, which in turn have a strong impact on currency values in the forex market.
Through policy tools and market actions, central banks guide economic growth, control inflation, and maintain confidence in their national currencies.
Interest Rates
Interest rates represent the cost of borrowing money within an economy. Central banks adjust interest rates as a primary tool to influence inflation and economic activity.
When a central bank raises interest rates, holding that currency becomes more attractive to investors seeking higher returns. Increased demand for the currency often leads to appreciation in its exchange rate.
Conversely, when interest rates are lowered, returns on investments decline. This can reduce demand for the currency and result in depreciation.
Open Market Operations
Open market operations involve the buying and selling of government securities by the central bank.
When a central bank purchases government bonds, it injects money into the financial system. This increase in money supply can weaken the currency’s value.
When it sells government securities, money is removed from circulation, which may strengthen the currency by reducing supply.
These operations are used to regulate liquidity and maintain stable financial conditions.
Foreign Exchange Interventions
Foreign exchange intervention occurs when a central bank directly buys or sells currencies in the forex market.
The objective is usually to stabilize exchange rates or counter excessive volatility. Large-scale interventions can influence currency prices in the short term. However, their long-term effectiveness often depends on broader economic fundamentals and policy consistency.
Liquidity and Financial Stability
Central banks also play a vital role in maintaining liquidity within the financial system. During periods of market stress, they act as lenders of last resort by providing funding to commercial banks and financial institutions.
This function helps prevent systemic risk, supports market confidence, and reduces the likelihood of widespread financial panic.
Role of Central Banks in Forex
