Treasury securities are debt instruments issued by the U.S. Department of the Treasury to fund government operations and pay down debt. These securities are widely regarded as some of the safest investments globally because they are backed by the “full faith and credit” of the U.S. government, meaning the government guarantees repayment of principal and interest. There are four main types: Treasury bills (T-Bills), Treasury notes (T-Notes), Treasury bonds (T-Bonds), and Treasury Inflation-Protected Securities (TIPS). Each varies by maturity and payment structure, catering to different investment needs and risk profiles.
Types of Treasury Securities
- Treasury Bills (T-Bills): Short-term securities maturing in one year or less. They are sold at a discount to face value and do not pay periodic interest, only the difference between the purchase price and face value at maturity.
- Treasury Notes (T-Notes): Medium-term securities with maturities ranging from 2 to 10 years. They pay interest every six months and return the principal at maturity.
- Treasury Bonds (T-Bonds): Long-term securities with maturities of 20 to 30 years, paying semiannual interest.
- Treasury Inflation-Protected Securities (TIPS): Offer protection against inflation by adjusting principal value based on changes in the Consumer Price Index (CPI), with interest payments calculated on adjusted principal.
How to Buy Treasury Securities
- Directly from the Government via TreasuryDirect: Investors can purchase new issues at auction through the official TreasuryDirect website (https://www.treasurydirect.gov/). Buying direct eliminates broker commissions and allows non-competitive bids in auctions.
- Through Brokerage Accounts: Treasury securities can also be purchased on the secondary market or at auction via brokerage firms like Fidelity, Vanguard, or Charles Schwab. This provides easier portfolio consolidation but may involve commissions or spreads.
Risks and Considerations
Though Treasury securities are considered extremely low risk, investors should be aware of certain factors:
- Interest Rate Risk: Rising interest rates cause market prices of existing fixed-rate Treasuries to fall. Selling before maturity in such environments can result in losses.
- Inflation Risk: Except for TIPS, fixed-rate Treasuries do not protect against inflation, which can erode purchasing power over time.
- Opportunity Cost: Compared to stocks and other higher-yielding assets, Treasury returns are modest, potentially limiting growth.
- Liquidity: While Treasuries are highly liquid in the secondary market, prices fluctuate based on market conditions.

Tax Treatment
Interest income from Treasury securities is fully taxable at the federal level but exempt from state and local income taxes. This tax advantage can be valuable for investors in states with high income tax rates. Gains from selling Treasuries before maturity may also have tax consequences depending on holding period and the nature of the gain.
Common Questions
- Can I lose money investing in Treasury securities? Holding Treasuries to maturity guarantees the return of your principal (assuming no default by the U.S. government, which is extremely unlikely). However, selling before maturity may result in losses due to price fluctuations.
- What is bond yield? It is the effective return on a bond based on its purchase price, coupon payments, and time to maturity. Yields move inversely with bond prices.
- Are Treasury securities suitable for retirement? Yes, they provide stability and predictable income, especially as part of a diversified portfolio, with TIPS offering inflation protection for retirees.
