The guaranteed minimum rates were discontinued on May 1, 1995. Each market day, the Treasury uses market bid yields for Treasury bills, notes, and bonds to create a yield curve based on the most actively traded Treasury securities. This yield curve relates the yield on a security to its time to maturity.
Bonds earn interest at the short-term rates during the first five years from date of issue.
Thereafter, interest is earned at the long-term rates. Otherwise, the rate is rounded to the nearest one-quarter of one percent. The table below displays the minimum rates and the time periods during which they were effective. The guaranteed minimum rate was discontinued for savings bonds and savings notes issued or entering an extended maturity period on or after May 1, 1995. These time periods are for bonds issued on the dates in column 1.
