Short-term Treasury Bills (T-Bills) are government securities that have maturities ranging from a few days to one year. Issued by the U.S. Department of the Treasury, they are considered one of the safest investments due to the creditworthiness of the U.S. government. These financial instruments are sold at a discount and redeemed at face value upon maturity, with the difference representing the interest earned by the holder.
Characteristics of Short-term T-Bills
Issuance and Maturities
- Maturities: Short-term T-Bills come with different maturities, namely 4 weeks, 8 weeks, 13 weeks, 26 weeks, and 52 weeks.
- Issuance Method: They are sold through auctions conducted by the U.S. Treasury, where competitive and non-competitive bids can be placed.
- Discount Method: Unlike traditional bonds, T-Bills do not pay periodic interest. They are issued at a discount to their face value and the investor receives the full face value at maturity.
Risk and Safety
- Credit Risk: T-Bills are considered virtually risk-free in terms of credit risk since they are backed by the full faith and credit of the U.S. government.
- Market Risk: While generally stable, the price of T-Bills can fluctuate with changes in interest rates. However, this risk is minimal given their short maturities.
Yield Calculation
The yield on T-Bills can be calculated using the following formula:
This formula uses a 360-day year convention for simplicity.
Investment Considerations
Liquidity
Short-term T-Bills are highly liquid, meaning they can be easily bought and sold in the secondary market. This liquidity makes them a popular choice for investors seeking a safe place to park their money for short periods.
Taxation
The interest earned on T-Bills is subject to federal income tax but exempt from state and local taxes. This tax exemption can make T-Bills particularly attractive to investors in high-tax states.
Comparison with Other Instruments
- Savings Accounts: Compared to savings accounts, T-Bills generally offer higher returns and similar levels of safety.
- Certificates of Deposit (CDs): T-Bills often have better liquidity and are backed by the government, unlike bank-issued CDs.
Historical Context
T-Bills have been a mainstay of U.S. government financing since their inception during the Great Depression in 1929. Their appeal has remained consistent due to their safety, simplicity, and favorable tax treatment.
