The Treasury Department has set the new Series I Bond rate at 3.2% for bonds purchased May-October 2026, down from 5.27% at peak but still offering inflation protection with zero risk.

I Bond Details

With the fixed rate component at 1.0%, current I Bonds lock in inflation protection permanently. Even when inflation is low, your return will always be 1.0% + whatever inflation is. Buy before the fixed rate potentially drops further.
