30-Year Treasury(redirected from 30 Year Treasury Security)
A debt security owed by the United States government for a period of 30 years. Each 30-year Treasury has a stated interest rate, which is paid semi-annually. Because the United States is seen as a very low-risk borrower, many investors see 30-year Treasury interest rates as indicative of the state of the wider bond market. Normally, the interest rate decreases with greater demand for 30-year Treasury securities and rises with lower demand. As with other U.S. Treasury securities, 30-year Treasuries are negotiable and may be traded on an exchange or over-the-counter. See also: yield, bond, treasury note, treasury bond, treasury bill.
