Treasury Lowers Rate on Series I Savings Bonds to 4.3%. There’s a Sweetener.

The new rate on the Treasury’s popular inflation-indexed savings bonds has been set at 4.3%, down from 6.89%, according to a notice Friday morning on the Treasury.gov website. The new rate, which applies to bonds issued from May 1 through Oct. 31, reflects a decline in inflation as measured by the consumer price index from September through March. The Treasury sets the rate on I Bonds every six months around May 1 and Nov 1.
