New I Bond rates won't be tantalizing but they could be decent
Two years ago, savers rushed to buy I Bonds online at TreasuryDirect.gov from May through October 2022 to lock in a 9.62% annualized rate that applies only to the first six months after the bond is issued.

Inflation isn't as scorching hot as it was back in 2021 and 2022, thankfully, but it hasn't cooled down enough to take the spark out of I Bonds.

On May 1, a new rate for Series I Savings Bonds will be announced by the U.S. Treasury's Bureau of Fiscal Service. We could, based on some estimates, end up looking at an annualized rate of around 4.28% that would apply for a six-month stretch, based on when the bond was issued, for I Bonds bought from May through October.

We are talking about a lower rate than what I Bonds had in late 2023 and early this year. The combined rate for I Bonds issued any time from last November through April was 5.27%. That rate applies only to the first six months after the bond was issued.

Last-minute savers who are able to buy I Bonds before late April — and have them issued in April — would see a 5.27% annualized rate for six months but then expect to see a lower inflation adjusted rate. See TreasuryDirect.gov to buy I Bonds online. Typically, you cannot wait until the very last minute, such as April 30, and receive an April issue date.

New rates for savings bonds are set each May 1 and Nov. 1.

The upswing in inflation in since the COVID-19 pandemic has put a spotlight on I Bonds and upcoming shifts in interest rates.

Based on the most recent inflation figures and how rates are calculated, the new rate for I Bonds could be 4.28%, according to Ken Tumin, a senior industry analyst at LendingTree. Tumin said inflation-adjusted rate that is announced May 1 can be expected to be 2.96% on an annualized basis. That rate is used as part of the math to calculate the annualized rate.

The inflation rate is on top of the fixed rate for all I Bonds, so it's an important number for current and future savers. The interest rate on I Bonds can change every six months after your initial purchase of the bond, based on inflation. If inflation runs hotter, the rate can go up. If inflation cools off, the rate can go down.

The fixed rate portion of an I Bond remains with the life of the bond. The fixed rate is 1.3% for I Bonds issued from November 2023 through April.

We won't know what the fixed rate will be for I Bonds issued from May through October until Treasury announces that rate on May 1. If it remained at 1.3%, though, I Bonds sold during that timeframe would have a combined rate of 4.28% — not as headline enticing as earlier bonds but still far better than keeping money in an everyday savings account or many lower-rate certificates of deposit.

Tumin said he'd expect the fixed rate to remain about the same or increase slightly for I Bonds issued from May through October.
