Treasury Bills (T-Bills): What They Are and How to Invest

When cash needs a safe place to grow without the ups and downs of the market, short-term government debt like Treasury Bills can be a go-to option. These securities sell below their face value and mature quickly, offering a predictable rate of return backed by the U.S. government. Here's what matters.

Key Takeaways

  • Short-term U.S. government debt with maturities up to 52 weeks.
  • Sold at discount; redeemed at face value for profit.
  • Virtually risk-free, exempt from state and local taxes.
  • Highly liquid; accessible via auctions and secondary markets.

What is Treasury Bills (T-Bills)?

Treasury Bills (T-Bills) are short-term securities issued by the U.S. Department of the Treasury to fund government operations. They have maturities ranging from a few days up to 52 weeks and are considered one of the safest investments due to being backed by the full faith and credit of the U.S. government.

Sold at a discount to their face value, T-Bills pay no periodic interest but return the full amount at maturity, making the difference your earnings.

Key Characteristics

T-Bills offer unique features that cater to conservative investors seeking liquidity and safety.

  • Maturities: Available in 4, 8, 13, 17, 26, or 52 weeks; most are auctioned weekly with some irregular open market operations for cash management.
  • Denominations: Sold in increments of $100, making them accessible for small and institutional investors alike.
  • Risk Profile: Virtually risk-free, they yield less than longer-term bonds or stocks but provide dependable preservation of capital.
  • Taxation: Interest income is subject to federal tax but exempt from state and local taxes, offering tax advantages compared to other fixed income.

How It Works

T-Bills function through discount pricing, where you purchase the bill below its face value and receive the full amount at maturity. The difference represents your rate of return.

For example, buying a $1,000 T-Bill for $950 with a six-month maturity yields a $50 profit. This return is calculated using discount yield formulas that reflect short-term market conditions and investor demand at auction.

Examples and Use Cases

T-Bills are widely used across industries and by various investors for cash management and risk mitigation.

  • Airlines: Companies like Delta utilize short-term government securities as a low-risk parking place for liquidity.
  • Retail Investors: Use T-Bills as a secure alternative to money market funds or as part of a diversified portfolio alongside options like low-cost index funds.
  • Institutional Investors: Often compare T-Bill yields with commercial paper and benchmark bond ETFs to optimize short-term cash allocations, including options in bond ETFs.

Important Considerations

While T-Bills offer safety and liquidity, their lower yields may not keep pace with inflation over time. You should consider your investment horizon and compare T-Bills to other fixed-income options to align with your financial goals.

Purchasing directly through TreasuryDirect or via brokers provides access to auctions with competitive and non-competitive bids, ensuring flexibility in how you manage your holdings.

Final Words

Treasury Bills offer a secure, short-term investment option with predictable returns backed by the U.S. government. To maximize benefits, compare current auction rates and consider your liquidity needs before investing.
