What Is a Treasury Bond?

A Treasury bond is a long-term debt security issued by the US government, with a maturity of 20 or 30 years. It pays a fixed interest rate every six months and repays its face value at maturity. Treasuries are backed by the full faith and credit of the US government.

Bills, Notes, and Bonds

Treasury bills mature in a year or less, Treasury notes in 2 to 10 years, and Treasury bonds in 20 or 30 years.

Interest Rate Risk

Long-term bonds’ prices change more when interest rates change, so their market value can fall significantly if rates rise.
