30-Year Treasury A U.S. Treasury debt obligation that has a maturity of 30 years. The 30-year Treasury used to be the bellwether U.S. bond but now most consider the 10-year Treasury to be the benchmark. Investopedia Says: The 30-year Treasury will generally pay a higher interest rate than shorter Treasuries to compensate for the additional risks inherent in the longer maturity. However, when compared to other bonds, Treasuries are relatively safe because they are backed by the U.S. government.
