Hint:

Central Bank control tools:

• Repo $\uparrow$ = Money supply $\downarrow$
• Repo $\downarrow$ = Money supply $\uparrow$

Answer 1

Step 1: Meaning of a Central Bank.
A Central Bank is the apex financial institution of a country that regulates and controls the monetary and banking system. It acts as the authority responsible for issuing currency, controlling credit, and maintaining financial stability in the economy. In India, the Reserve Bank of India (RBI) performs the functions of the Central Bank.

Step 2: Major functions of a Central Bank.
The Central Bank performs several important functions in an economy. These include:
- Issue of currency: It has the sole authority to issue paper currency in the country.
- Banker to the government: It manages the government’s accounts, receipts, and payments and provides financial advice to the government.
- Banker’s bank: Commercial banks keep a portion of their reserves with the Central Bank and can borrow from it during financial difficulties.
- Controller of credit: The Central Bank regulates and controls the supply of money and credit in the economy to maintain economic stability.

Step 3: Control of money supply through Repo Rate.
Repo Rate is the rate at which the Central Bank lends money to commercial banks for short periods against government securities.
- When the Central Bank increases the repo rate, borrowing from the Central Bank becomes expensive for commercial banks. As a result, banks reduce lending to the public, which decreases the money supply in the economy.
- When the Central Bank reduces the repo rate, borrowing becomes cheaper for banks. This encourages banks to lend more money to businesses and consumers, thereby increasing the money supply in the economy.

Step 4: Control of money supply through Open Market Operations.
Open Market Operations refer to the buying and selling of government securities by the Central Bank in the open market.
- When the Central Bank sells government securities, people and banks purchase these securities and pay money to the Central Bank. This reduces the amount of money circulating in the economy.
- When the Central Bank buys government securities, it pays money to banks and the public, which increases the money supply in the economy.

Final Answer:
A Central Bank performs functions such as issuing currency, acting as banker to the government and banks, and controlling credit. It controls the money supply mainly through tools like the repo rate and open market operations, which regulate lending and the circulation of money in the economy.
