Treasury bills

commonly known as T-Bills, are short-term government securities used by governments to raise money and manage their short-term financial needs. They are generally issued for a period of less than one year and are usually sold at a price below their face value. When the Treasury Bill reaches maturity, the investor receives its full face value, with the difference representing the return on the investment. Because they are backed by the government that issues them, Treasury Bills are generally considered to be relatively low-risk investments.
