As consumer prices rise amid the Iran war, some investors are looking for ways to combat inflation.
The only option Series I bonds Some experts say a government-backed, virtually risk-free asset may now be more attractive. But others may prefer more flexible options.
The U.S. Treasury Department announced last week that newly purchased I bonds will pay 4.26% annual interest through October 31, down from the 4.03% yield offered through April 30.
When inflation rises, “I bonds definitely become more attractive,” said Ken Tumin, founder of the blog DepositQuest.com, which tracks I-bond rates as well as other deposit accounts.
Demand for I bonds has increased before amid rising inflation. As yields are tied to the consumer price index, bond yields reached a record high of 9.62% in May 2022 and investors flocked to the assets.
As prices cooled, many redeemed their I bonds. But there has been more interest since the March inflation data, according to David Enna, founder of Tipswatch.com, a website that tracks Treasury inflation-protected securities, or TIPS and I bond yields.
The consumer price index, or CPI, a key indicator of inflation, rose 3.3% year-over-year in March 2026, up from 2.4% in February, the Bureau of Labor Statistics reported in April.

Disadvantages of I bonds
If you’re considering I bonds, experts say it’s important to know the balance between them, especially when compared to other assets.
Bonds are not as flexible as Treasury bills, money market funds, or high-yield savings accounts. For newly purchased I bonds, you won’t be able to access the cash for at least a year, and if sold within five years, there will be a three-month interest penalty.
If your investment timeline is only around a year, Enna recommends treasury bills over I bonds because the three-month interest penalty reduces your return.
