A treasury bond, or T-bond, is a negotiable, coupon-bearing debt obligation issued by the U.S. government and backed by its full faith and credit, having a maturity of more than 7 years. Interest is paid semi-annually. Treasury bonds are exempt from state and local taxes. These securities have the longest maturity of any bond issued by the U.S. Treasury, from 10 to 30 years. The 30-year bond is also called the "long bond." Denominations range from $1000 to $1 million. Treasury bonds pay interest every 6 months at a fixed coupon rate. These bonds are not callable, but some older Treasury bonds available on the secondary market are callable within five years of the maturity date.
