A Treasury Bill, commonly referred to as a T-Bill, is a short-term promissory note issued by the U.S. Treasury. T-Bills have maturity periods ranging from a few days up to one year. Unlike Treasury notes and Treasury bonds, which have intermediate and long-term maturities, respectively, T-Bills are a safer, more liquid, and typically lower-yielding investment option.
Structure and Sale of T-Bills
Discount Issuance
Treasury Bills are sold at a discount to their face value. The investor purchases the T-Bill for an amount less than its face value, with the understanding that the U.S. Treasury will redeem the bill at its full face value upon maturity. The difference between the purchase price and the redemption value represents the interest income to the owner.
For example:
An investor buys a 6-month T-Bill with a face value of $10,000 for $9,800. At maturity, the U.S. Treasury pays the investor $10,000. The $200 difference is the interest income.

Special Considerations
Safety
T-Bills are considered one of the safest investments because they are backed by the “full faith and credit” of the U.S. government. Hence, they carry virtually no risk of default.
Liquidity
Due to their short maturity periods, T-Bills are highly liquid and can be easily converted to cash through the secondary market before they mature.
Tax Treatment
Interest income on T-Bills is exempt from state and local taxes but is subject to federal income tax.
Historical Context
Treasury Bills have been a staple in the U.S. government’s toolkit for managing short-term funding needs since their inception during World War I. Over the decades, they have grown to be a significant part of the broader U.S. government debt market, playing a vital role in the overall financial system.
Practical Applications
Portfolio Diversification
T-Bills are often used by investors to diversify portfolios, reduce risk, and ensure liquidity. They are a key component for managing short-term cash needs and are utilized by individuals, institutional investors, and governments.
Interest Rate Benchmark
The yield on T-Bills serves as a benchmark for interest rates and is a critical indicator of the overall health of the financial market.
