Definition: A Treasury Bond (T-Bond) is a long-term debt security issued by a national government—most commonly the U.S. Department of the Treasury—to raise capital and fund public spending. Treasury bonds have maturities of 20 to 30 years, pay a fixed interest (coupon) every six months, and are considered virtually risk-free because they are backed by the full faith and credit of the government.
