Composite rate will fall from 6.89% to 4.30%, but the fixed rate of 0.9% is highly attractive for long-term holders.

Surprise! I Bonds purchased from May to October 2023 will get a fixed rate of 0.9% and a composite rate of 4.3%, TreasuryDirect announced this morning, jumping the gun on its expected May 1 press release. It’s all right there on its homepage:
At first, I thought this was posted by mistake, jumping ahead of Monday’s announcement. In the 12 years I have been writing about I Bonds, the new rates have never been announced early.
A few minutes later, the TreasuryDirect site went down, possibly because of the “what the hell?” factor driving traffic. But I was able to return to the site a bit later and it loaded, with the same information.
I had been speculating that the I Bond’s new fixed rate would be about 0.6%, so 0.9% is great news. It is the highest fixed rate since the reset in November 2007. The fixed rate tells you how much the I Bond will earn above official U.S. inflation. It is equivalent to the “real yield to maturity” of a Treasury Inflation-Protected Security.
The site has the full information on the new rate and how it was determined, combining the new inflation-adjusted variable rate of 3.38% with the new fixed rate of 0.9%.
| Fixed rate | 0.90% |
|---|---|
| Semiannual (1/2 year) inflation rate | 1.69% |
| Composite rate formula: [Fixed rate + (2 x semiannual inflation rate) + (fixed rate x semiannual inflation rate)] | [0.0090 + (2 x 0.0169) + (0.0090 x 0.0169)] |
| Gives a composite rate of | [0.0090 + 0.0338 + 0.0001521] |
| Adding the parts gives | 0.0429521 |
| Rounding gives | 0.043 |
| Turning the decimal number to a percentage gives a composite rate of | 4.30% |
TreasuryDirect’s page listing the history of fixed rates now includes the 0.9% rate, more than doubling the 0.4% fixed rate in effect for purchases through April 30.
The current composite rate for I Bonds purchased through April 30 is 6.89% and that will fall to 4.3% for purchases from May to October 2023. But the fixed rate of 0.9% makes the May-to-October purchases very attractive.
Just as an aside, the new composite rate for I Bonds purchased from November 2022 to April 2023 will be 3.79%, which reflects the fixed rate of 0.4% and inflation-adjusted rate of 3.38%.
TreasuryDirect said this week that the last day to place orders for the 6.89% rate was yesterday, April 27. (I placed my order on April 26.) So I am assuming that any I Bond purchased today will get the new May 1 rate. And that could be why the Treasury decided to post the new rate information, since we can assume it will take effect for purchases today.
EE Bonds
The Treasury also announced that the new fixed rate for EE Bonds will be 2.5% for savings bonds issued from May 1 to Oct. 31, 2023. This is up from the current fixed rate of 2.1%. The Treasury is retaining the policy that EE Bonds are guaranteed to double in value if held for 20 years, creating an effective interest rate of 3.53%.
Gift box strategy?
The Treasury limits purchases of I Bonds to $10,000 per person per year, so investors need to think through a strategy for the best time to invest. If you were planning on holding the I Bonds for less than 2 years, the smart move was to buy in April, locking in an annual return of about 5.4%. For long-term holders, buying in May is preferable, locking in the 0.9% fixed rate for the full 30-year term of the I Bond.
Earnings from the new 0.9% fixed rate create a breakeven period of about 3 years, 8 months. If you plan to hold less than 3 years, 8 months, buying in April works out better. Anything longer will make the May rate more attractive.
The dilemma: Now the fixed rate rises to 0.9%, but you already bought your full allocation this year. (True for me.) What do you do?
If you bought in April, like I did, you can still use the gift box strategy if you have a spouse or a trusted friend or family member with a separate TreasuryDirect account. Using this strategy, anytime before the end of October you can place $10,000 into the TreasuryDirect gift box, assigned to your partner, and your partner would do the same for you.
Some basics of the gift box strategy:
- When you place an I Bond into the gift box, it begins earning interest in the month of purchase, just like any other I Bond, and continues earning interest just like any I Bond. However, this money is no longer yours. It belongs to the recipient of the gift.
- The purchase does not count against your purchase limit for that year. It will count against the purchase limit for the recipient, in the year it is granted.
- Gift purchases are limited to $10,000 for each gift, but you can make multiple gift purchases of $10,000 for the same person. But the recipient can only receive one $10,000 gift a year, and that gift counts against their purchase limit for that year.
- You must provide the recipient’s name and Social Security Number when you buy a gift. The recipient doesn’t need to have a TreasuryDirect account … yet. Only a personal account can buy or receive gifts. A trust or a business can’t buy a gift or receive a gift.
- “I Bonds stored in your gift box are in limbo,” Harry Sit notes in his article. “You can’t cash them out because they’re not yours. The recipient can’t cash them out either because the bonds aren’t in their account yet.”
- The recipient will need to open a TreasuryDirect account to receive the I Bond. Once it is delivered, the money is the recipient’s, who can then cash out or continue to hold the I Bond.
Rolling over 0.0% fixed rates?
If you are holding I Bonds with 0.0% fixed rate — especially those held for five years or more — you can consider redeeming those older I Bonds for new ones with the 0.9% fixed rate. When you redeem, you will owe federal taxes on the interest earned.
I think this is a sound strategy, especially if you don’t want to raise another $20,000 to buy I Bonds this year in two separate accounts.
One key thing to consider is to wait until the current variable rate of 6.48% has completed and the new rate of 3.38% has begun. You have until October to make a purchase of I Bonds with the 0.9% fixed rate. No rush.
If you have held the I Bond less than five years, consider waiting an extra three months to have the three-month interest penalty apply to the lower composite rate.
Projecting the fixed rate
We still don’t know how the Treasury decides on setting the fixed rate of the I Bond, but it’s becoming clear that the rate tracks higher and lower with real yields of Treasury Inflation-Protected Securities. We just don’t know how much. TreasuryDirect recently added this “less vague” statement to its FAQ page on I Bonds, clearly indicating that market real yields are a factor in setting the fixed rate:
The Secretary of the Treasury, or the Secretary’s designee, determines the fixed rate. The rate is based on market rates that have been adjusted to account for the value of components unique to savings bonds. These include the early redemption put option, tax deferral feature, deferred purchase feature, and Treasury’s administrative costs.
Here is the final version of my two prediction models for the I Bond’s fixed rate. The columns on the left show how the fixed rate compares with the average of the 10-year real yield over the last six-month rate-setting period. The columns on the right show how the fixed rate compares with the latest real yield of the 10-year TIPS.

I have limited these numbers to the times when the Treasury raised the fixed rate above 0.0% going back to November 2013, solidly in the era of Federal Reserve intervention in the U.S. bond market.
If you look at the calculation on the right, the average yield spread between the latest 10-year TIPS and the I Bond fixed rate is 38 basis points. The new fixed rate of 0.9% is 36 basis points below the current 10-year real yield of 1.26%. So that looks good as a predictor, but this calculation isn’t very reliable except to predict if the fixed rate is likely to rise or fall.
The half-year average calculation is more reliable, I think, and in more recent rate changes the ratio has been in the range of 0.59 to 0.77. Today’s fixed rate announcement of 0.9% puts the ratio at 0.66, right in the middle. I think this half-year-average formula is more reliable, but still nowhere near perfect.
