Investors who want to set aside money for future expenses often face a timing problem. A savings account offers access, while a longer-term investment may expose money to price swings or withdrawal restrictions. U.S. Treasury bills offer another option for people who want to schedule when portions of their money mature.
A Treasury bill ladder is a way to spread purchases across different maturity dates rather than investing all available money in one bill.
What Is a Treasury Bill?
Treasury bills are short-term securities issued by the U.S. Department of the Treasury. They are available in terms ranging from four weeks to 52 weeks.
Unlike Treasury notes and bonds that generally pay interest periodically, bills are typically sold at a discount to their face value. When a bill matures, the investor receives its face value. The difference between the purchase price and face value represents the interest earned.
For example, an investor might pay less than $10,000 for a bill with a $10,000 face value. At maturity, the Treasury pays the $10,000 face value. The actual purchase price and yield are determined by the auction.
How a Ladder Works
A ladder divides money among securities with different maturity dates.
An investor might divide a sum into several portions and purchase bills that mature at different intervals. As each bill matures, the investor can use the proceeds for planned expenses or reinvest them in a new bill.
The goal is to avoid having the entire investment tied to a single maturity date. It can also create a recurring schedule of cash becoming available.
The exact ladder depends on the investor's cash needs. Someone saving for quarterly tax payments may use a different schedule from someone setting aside money for a home renovation expected next year.
Reinvestment and Interest-Rate Risk
A ladder does not guarantee a particular return. When a bill matures, the investor may be able to reinvest at a higher or lower yield depending on market conditions.
This is reinvestment risk. If interest rates decline, newly purchased bills may offer lower yields than the ones that matured. If rates rise, reinvested money may earn more.
An investor who sells a Treasury bill before maturity may also receive more or less than the purchase price, depending on market conditions. Holding to maturity avoids that particular need to sell at a market price, assuming the investor does not need the money early.
Buying Through TreasuryDirect or a Brokerage
Individuals can purchase eligible Treasury bills through TreasuryDirect or through banks and brokerage firms that participate in Treasury auctions or offer Treasury securities in the secondary market.
TreasuryDirect lists a minimum purchase amount of $100, with purchases generally made in $100 increments. Brokerage platforms may have their own procedures, fees or minimums.
Investors should understand whether they are buying at auction or in the secondary market. They should also check the maturity date, price, yield and any transaction costs.
Tax Treatment
Interest earned on Treasury bills is generally subject to federal income tax but exempt from state and local income taxes. That distinction can matter to investors comparing Treasury bills with bank deposits or other short-term investments.
Tax reporting and timing can depend on the security and the investor's circumstances. Keeping purchase confirmations and tax documents can make reporting easier.
The Bottom Line
A Treasury bill ladder can help investors organize short-term money around known spending dates. It offers a structured approach to maturities, but it does not lock in future reinvestment rates or eliminate every risk. Before building a ladder, investors should match maturity dates to their cash needs and compare the yield after considering taxes and any brokerage costs.
