A Central Bank (Central Bank) is an institution that has the exclusive authority to issue currency for a nation or a specific territory. It is responsible for managing the monetary and payment systems of that nation/territory, as well as implementing monetary policy. The Central Bank is the leading financial institution within a country or territory and operates with a certain degree of independence from the government.

Roles of the Central Bank

Firstly, the Central Bank has the exclusive right to issue currency for a nation or territory. Each central bank worldwide is authorized to issue only one currency for the country it serves, or for countries/territories that use that currency as their primary medium of exchange. For instance, the State Bank of Vietnam (SBV) is the sole issuer of the Vietnamese dong, the Federal Reserve (Fed) has the monopoly on issuing US dollars for the United States and other countries that use the USD as the main currency, such as Zimbabwe and Ecuador. The European Union uses the Euro as the common currency issued by the European Central Bank (ECB).

Another crucial role of the Central Bank is to use monetary policy tools. The three main monetary policies of the Central Bank are open market operations (OMO), reserve requirements, and interest rate control. These monetary policies directly affect the money supply and credit flow in the economy, helping central banks achieve their economic goals. For example, the Central Bank might ease monetary policy and lower interest rates to stimulate the economy or tighten monetary policy and raise interest rates to curb inflation.

The Central Bank is the central entity of a nation’s economy, responsible for overseeing, regulating, and setting regulations within the payment system of a nation or territory. In the modern economy, millions of financial transactions occur daily. For the financial system to function efficiently, regulations must be robust and standardized. Additionally, the Central Bank is involved in the global payment system alongside other national central banks.

The Central Bank is also known as the “lender of last resort.” If commercial banks face liquidity shortages and cannot cover them, the Central Bank steps in to provide liquidity by lending money to commercial banks in distress. Sometimes, the Central Bank also lends money to the government by purchasing government bonds when the government needs to raise funds for increased spending or public investment, contributing to GDP growth.

Lastly, the Central Bank controls and manages the foreign exchange and gold reserves of a nation. While it can issue the domestic currency of its nation, it cannot print foreign currency. Thus, managing a nation’s foreign exchange reserves is critical for international payments and mitigating the risk of foreign currency defaults.

Objectives of the Central Bank

Central banks worldwide have specific objectives, but the most important goal of every central bank is price stability, or in other words, controlling inflation. Using monetary policy tools, the Central Bank can influence the money supply, which in turn can regulate inflation. Typically, central banks in various countries or territories set an inflation target, usually around 2-3% per year. Excessive inflation above the target leads to higher prices in the economy, reducing the currency’s value, while deflation causes economic stagnation and can lead to a deflationary spiral.

Additionally, central banks may have secondary objectives such as employment stability, promoting GDP growth, or maintaining exchange rate stability. For example, the Fed’s goals include stabilizing inflation, maximizing employment in the US, and maintaining moderate long-term interest rates.
