T-Bills are short-term debt instruments issued by the government to regulate the money supply in the economy.

The Reserve Bank of India (RBI) is responsible for issuing T-Bills in India.

The typical maturity period of T-Bills in India is 91 days.

The minimum amount required to invest in T-Bills in India is ₹25,000.

T-Bills are traded in India both in the over-the-counter (OTC) market and on stock exchanges.

T-Bills are considered to be very low-risk investments, as they are backed by the full faith and credit of the government. However, there is a small risk of default if the government is unable to repay its debts.

The rate of return on T-Bills is fixed at the time of issuance and remains constant until maturity.

The rate of return on T-Bills is determined by a combination of factors, including the RBI's monetary policy, the government's fiscal policy, and the market forces of demand and supply.

T-Bills offer a number of advantages to investors, including low risk, a fixed rate of return, and high liquidity.

T-Bills also have some disadvantages, including a low rate of return, a short maturity period, and a lack of flexibility.

T-Bills are attractive to a wide range of investors, including individuals, banks, corporations, and other financial institutions.

T-Bills can be used in portfolio management in a variety of ways, including as a safe haven asset, a short-term investment, and a hedging instrument.

T-Bills have a number of positive impacts on the economy, including helping to regulate the money supply, control inflation, and stabilize the foreign exchange rate.

The T-Bill market in India has been experiencing increasing demand, decreasing supply, and rising interest rates in recent years.

The T-Bill market in India is expected to continue to grow in the future, with increased volatility and greater integration with the global market.
