I Bond Earnings Rate 0.00%, Fixed Rate 0.10%
For more information, see:
The 0.00% earnings rate for I bonds bought from May through October 2009 will apply for their first six months after issue. The earnings rate combines a 0.10% fixed rate of return with the -5.56% 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.
The CPI-U decreased from 218.783 to 212.709 from September 2008 through March 2009, a six-month change of -2.78%.
