- Treasury securities are U.S. government debt, but bills, notes, and bonds differ in maturity and cash-flow structure.
- Buying at auction and trading later in the secondary market are different transactions; price and yield can change after issuance.
- Holding to maturity reduces concern about interim market price for money that truly can stay invested, but it does not eliminate inflation or reinvestment risk.
- Choose maturity from the spending date and portfolio role rather than trying to predict the next rate move.
Rules, tax treatment, product terms, fees, market structure, and provider practices can change. Use this material as general context, then confirm current official documents and provider terms before acting.
Bills, notes, and bonds solve different maturity needs
Treasury bills are short-term securities and are commonly issued at a discount to their face value. Notes and bonds have longer maturities and generally pay periodic interest. The useful distinction is not the label itself, but when principal is repaid and what cash flows are received along the way.
Know what an auction does
TreasuryDirect publishes auction announcements, dates, terms, and results. Investors can participate through eligible channels or buy outstanding securities later through a brokerage. An auction establishes terms for a new issue or reopening; it does not mean the security’s market value will remain fixed after issuance.
Price and yield move in opposite directions
Once a marketable Treasury is trading, its price and yield generally move in opposite directions. Changes in prevailing interest rates can therefore change the security’s market value. Longer-maturity securities generally have greater price sensitivity than very short maturities. If the plan may require a sale before maturity, interim price risk belongs in the decision.
Use maturities to match future needs
A ladder spreads maturity dates instead of placing all cash at one point on the yield curve. That can reduce the risk of having to reinvest everything at one future rate, but it also creates more positions to track. Keep the ladder only as complex as the goal requires.
When should principal become available?
Is periodic interest useful, or is a single maturity payment simpler?
Could the security need to be sold before maturity?
What happens to proceeds when each security matures?
Verify the actual security before buying
Record the CUSIP or security description, maturity date, coupon if any, price or auction result, yield measure, settlement date, and where the security will be held. Those details prevent a generic “Treasury” decision from hiding the term the investor actually purchased.
