I-Bond Rates: November 2, 2009 through April 30, 2010

The Bureau of the Public Debt today announced an earnings rate of 3.36% for Series I Savings Bonds issued from October 2, 2009 through April 30, 2010. Press Release

The 3.36% earnings rate for I bonds bought from November 2, 2009 through April 30, 2010 will apply for their first six months after issue. The earnings rate combines a 0.30% fixed rate of return with the 3.06% annualized rate of inflation as measured by the Consumer Price Index for all Urban Consumers (CPI-U). When the inflation rate is less than zero, a bond's earnings rate is less than its fixed rate (but the earnings rate is never less than zero).

The fixed rate applies for the 30-year life of I bonds purchased during this six-month period.
Earnings rates for I bonds are set each May 1 and November 1. Interest accrues monthly and compounds semiannually. Bonds held less than five years are subject to a three-month interest penalty. I Bonds have an interest-bearing life of 30 years.
