What Are Series EE Bonds?
Series EE savings bonds are issued and backed by the U.S. government and are designed to double the purchaser’s investment in 20 years. They came to market in April 1997 and replaced the series E bond. Series EE bonds issued between April 1997 and May 2005 will pay interest, compounded semi-annually, at a rate equal to 90% of the average 5 year treasury bond yield for the previous 6 months. Bonds issued after May 2005 will accrue interest at a fixed rate for the life of the savings bond. The rates are determined each May and November and your savings bond will carry a rate equal to the last officially announced interest rate.
