The I Bond Rate May 2025 announcement brings important updates for anyone interested in this government-backed investment. The U.S. Treasury has unveiled a new composite rate for I Bonds purchased between May 1 and October 31, 2025. With inflation trends shifting, this rate is important for both new and existing I Bond holders.
As of May 1, the I Bond Rate May 2025 is a combination of two components: a fixed rate and an inflation-adjusted rate. While the fixed rate has slightly decreased to 1.10% (down from 1.20%), the inflation component has increased to 2.86% (up from 1.90%). The resulting composite rate stands at 3.98%. This is a notable adjustment compared to the previous rate period, where the inflation component was lower, highlighting the impact of ongoing inflation trends.

I Bond Rate May 2025: What’s New for New Purchases
For those considering purchasing I Bonds in the next few months, the I Bond Rate May 2025 offers a relatively attractive return. The fixed rate, while slightly reduced, is still higher than many other low-risk investment options. Combined with the inflation rate, which adjusts based on the recent inflation data from October 2024 to March 2025, I Bonds remain a popular choice for conservative investors seeking to protect their money against inflation.
I Bond Rate May 2025: How It Impacts Existing Bonds
If you already own I Bonds, the I Bond Rate May 2025 will affect your interest payments in the upcoming periods. The inflation component of 2.86% will be added to the bond’s interest rate for the next six months, even if you purchased your bond earlier. However, keep in mind that the fixed rate assigned when you bought the bond remains the same for its entire lifespan. This means that some bondholders may see a significant improvement in their returns, depending on when they initially invested.
