What to know

Key risks

  • Interest-rate risk. If market yields rise, the price falls — and more so the longer the maturity. See the rate-sensitivity table above.
  • Inflation risk. Fixed coupons lose purchasing power if inflation rises. TIPS are designed to offset this; nominal bills, notes and bonds are not.
  • Reinvestment risk. Coupons, and principal at maturity, may have to be reinvested later at lower rates than today's.
  • Liquidity / price risk. Selling before maturity means taking the market price at that time, which can be above or below the indicative value shown here.

Tax

Interest on U.S. Treasuries is subject to federal income tax but is generally exempt from state and local income tax.

How Treasuries are bought

New issues are sold at auction (including directly via TreasuryDirect.gov); outstanding securities trade on the secondary market through a broker. This site is for research only and does not sell or recommend securities.
