The U.S. Department of the Treasury has announced that newly purchased Series I bonds will now yield an annual interest rate of 5.51%, up from 4.26% for purchases made before October 31. This new rate consists of a variable portion of 4.08%, which is tied to inflation, and a fixed portion of 1.40%, the latter being the highest fixed rate since 2006, up from 0.90% announced in April.
The increase in I bond rates comes as inflation concerns resurface, with the consumer price index rising 3.7% in September 2026 compared to the previous year. Factors contributing to this inflation include geopolitical tensions, tariffs, and increased demand in various sectors.
Experts suggest that the attractiveness of I bonds may draw investors back, especially as inflation expectations rise, with a one-year inflation outlook reaching 3.9%, the highest in over three years. Current I bond investors will see their variable rates adjusted every six months, while their fixed rates remain unchanged for the duration of their investment.
This structure makes I bonds a potentially appealing option for those looking to hedge against inflation
