What is a Central Bank and its Functions?

Before delving into how the central bank influences the trade market, it is crucial to know the importance of a central bank, and its functions. The central bank is a public institution responsible for implementing monetary policies for a country. Through this, they ensure price stability and economic growth. The central bank sets official interest rates, either by increasing or decreasing them depending on the economic situation. They also manage the currency and control the money supply by issuing coins and notes. The central bank is responsible for overseeing the interbank market by ensuring the smooth operation of the banking system.

The Role of Central Banks on Currency Exchange Rates

Central banks influence currency exchange rates in multiple ways. They are as follows:

Monetary Policy Adjustments: Central banks adjust interest rates according to the economic situation in the country. They can increase or decrease interest rates to boost economic growth, or to manage inflation. When the central bank raises interest rates, it generally attracts more foreign investment. It also leads to increased demand for currency and higher foreign exchange rates. Similarly, if the interest rates are lowered, it can lead to depreciation in the value of the currency.

Management of Foreign Exchange Reserve: Foreign exchange reserves, also known as forex reserves, are assets held by the central bank. They are generally held in foreign currencies like USD (United States Dollar) and other assets like gold and silver. The major purpose of possessing these assets is to influence the foreign exchange rate of the country’s currency. By trading the foreign currencies, the central bank can adjust the value of the country’s currency.

To Control Inflation: Central banks play a crucial role in mitigating inflation. Inflation can reduce the value of the currency of a country, making it less desirable for investors. The central bank implements policies to manage inflation and to stabilise the value of the currency. They achieve it through monetary policies and by trading government securities in the open market (Open Market operations).

Economic Data Release: Central banks release economic reports and data that influence currency value and shape market expectations. The reports aid with policymaking and allow central banks to closely monitor data regarding major aspects of the country’s economy. The reports include data on economic growth, GDP, employment, exchange rates, etc. The information from the reports on foreign exchange markets can be used by traders to make better trade decisions and manage risks.
