I Bonds offer trade-up opportunity with new 4.3% fixed rate.

The rate for Series I savings bonds, also known as I-bonds, will reset to 4.3% from May 1 to the end of October, including a 0.9% fixed rate and a 1.69% six-month rate, according to the Treasury Department. While the new rate is lower than the previous six-month rate of 6.89%, it is higher than estimates based on known inflation data, making it a potentially attractive option for investors seeking a fixed rate of return.
