Treasury bonds are U.S. government debt instruments with maturities typically ranging from 10 to 30 years. They pay a fixed interest rate semiannually and return the principal at maturity. Considered among the safest investments due to the backing of the U.S. government, they are widely used by investors seeking stable income and capital preservation. Treasury bonds play a key role in financial markets, influencing interest rates and serving as benchmarks for other debt securities.
