March CPI-U numbers released: April 2025 issue I Bonds compelling
As always, now (along with the release of the September CPI-U) is one of the best times to consider purchasing I Bonds. The reason for this is that we now know what the rate of return for April 2025 I Bonds will be for both the first and second six month periods, which is important since I Bonds must be held for 12 months before they can be redeemed.
Using the CPI-U data from September 2024 (315.301) and March 2025 (319.799) (courtesy of inflationdata.com), we can calculate the variable rate for the second 6 month period for April 2025 issue I Bonds.
That means these bonds would earn a composite rate of 3.11% (using 1.2% fixed & 0.95% variable) for the first 6 months and 4.08% (using 1.2% fixed & 1.43% variable) for the second 6 months. In the current interest rate environment, an April I Bond purchase isn't a bad choice when compared to something like the 52 Week T-Bills @ 3.989% APY that will be issued on 4/17/25
In my opinion, April 2025 I Bonds are a reasonable choice, particularly for the 1.2% fixed rate if you plan to hold them long term. Based on the spread between I Bonds and TIPS, David Enna of tipswatch.com projects that the new fixed rate will fall slightly to 1.10%, which would make a purchase before the end of the month a bit more attractive. FWIW, Mrs. Frugalson and I will be maxing out our 2025 limit before the end of April.
