May 2, 2022 update: Treasury holds I Bond’s fixed rate at 0.0%; composite rate soars to 9.62%.
By David Enna, Tipswatch.com
Back in December 2021, I wrote an article contending there was a “slim chance” that the fixed rate for the U.S. Series I Bond could rise at the Treasury’s next reset on May 1, 2022. The point of that article was to demonstrate that even if the fixed rate did rise, an investment before May 1 would make more financial sense than one after May 1.
Pre-publication, I ran that article idea by a few inflation-watching experts and got responses like you see on Twitter with the meme of the laughing woman spitting out water. Basically: “Are you crazy? There is no way the Treasury is going to raise the I Bond’s fixed rate in May. Not going to happen!”
At the time, understand, the Federal Reserve was only hinting it might begin raising interest rates in 2022. And the 10-year TIPS had a real yield of -1.08%, giving the I Bond a huge 108-basis-point advantage.
But things have changed, as I speculated could happen in that December article:
Eventually, both real and nominal interest rates should begin rising, ending nearly two years of absurdly low rates, at a time when inflation has surged to a 30-year high. Finally, will investors see a reasonable return on safe investments? That’s my hope.
As of Friday’s market close, the real yield of a 10-year TIPS had increased to -0.08%, jumping 100 basis points higher in just five months. The I Bond now has only an 8-basis-point advantage over a 10-year TIPS. Yet, I’d say the possibility of a higher fixed rate remains very slim — for the May reset. In November, much more likely.
How is the fixed rate set?
The Treasury has no announced formula for setting the I Bond’s fixed rate, and everything you read here is informed speculation. The Treasury sometimes does weird things. I’ve been handicapping the fixed-rate adjustments for 11 years, and my best speculation is that the yield of a 10-year TIPS needs to be above zero for the Treasury to even consider raising the fixed rate. Once the 10-year TIPS real yield rises to about 0.50%, a fixed rate above zero becomes likely. We are still a bit away from that.
I don’t think the fixed rate is going to rise at the May 1 reset. (The announcement will come at 10 a.m. EDT on May 2, because May 1 falls on a Sunday.)
Here is a chart showing every instance where the I Bond’s fixed rate was set higher than zero, going back to 2008, and comparing that fixed rate with the then-current real yields of 5- and 10-year TIPS:
Notice that over the last 13 years, there is no case when the I Bond’s fixed rate was above zero and the 10-year TIPS yield was negative to inflation. The closest was the May 2016 reset, when the 10-year TIPS was yielding only 0.12%. At that time, annual inflation was running at only 1.1%, so the Treasury may have been using the 0.1% fixed rate to spur interest in I Bonds.
Today, U.S. inflation is running at 8.5% and investors are flooding into I Bonds. Over the past six months, nearly $11 billion in I Bonds have been issued, compared with around $1.2 billion during the same period in 2020 and 2021, the Wall Street Journal reported last week.
The I Bond’s next composite rate is going to be 9.62%, even with the fixed rate at 0.0%. The Treasury doesn’t need to spur sales. By all logic, it will be holding the I Bond’s fixed rate at 0.0%. Am I totally certain of that? Nope, more like 98.5% certain. The Treasury sometimes does weird things.
Why buying before May 1 makes the most sense
Let’s say the Treasury surprises us and raises the fixed rate to 0.2% for May to October purchases of I Bonds. That would be a shocker! (It won’t happen, but let’s pretend … ) On a $10,000 investment, that 0.2% bonus is worth $20 in the first year, and will compound slightly higher in future years.
If you invest before May 1, you lock in earnings of $356 in the first six months, and then you will earn $498 in the second six months, for a total of $854 in the first 12 months. If you buy after May 1 and get a fixed rate of 0.2%, you will earn $491 in the first six months and then an unknown amount in the second six months.
If you buy after May 1, you miss out on the initial boost of $356, which is equal to about 13 years of the 0.2% fixed-rate bonus, even if you calculate in compounding. So if you buy in May and luck out with a higher fixed rate, it will still take you 13 years to catch up with the person who bought in April.
Here are the numbers, based on my projection of a gradually declining inflation rate over the next 15 years:
And if the fixed rate doesn’t rise?
A lot of readers have been asking me why it doesn’t make more sense to wait until May and jump directly into the 9.62% rate instead of the current rate of 7.12%. The rationale for buying in April is simple: You get a full six months of 7.12% (annualized) and then a full six months of 9.62% (annualized). With compounding that works out to an annual return of 8.54%.
If you buy after May 1, you get 9.62% annualized for the first six months and then an unknown rate for the next six months. When the variable rate resets in November people who bought in April and those who bought in May will get that new rate for six months. There is no advantage to buying in May, for people who intend to buy I Bonds for the mid- to long-term.
The one exception is for an investor who wants to hold the I Bond exactly 12 months and then redeem it. For that person, buying in May does make some sense because it puts the 9.62% return in the first six months. If the I Bond is redeemed after 12 months, the three-month interest penalty will be applied to the next variable rate, which will probably be lower.
People who buy in April should hold the I Bond for 15 months before redeeming, to make sure the three-month penalty is not applied to the 9.62% rate.
Our fixed rate future
There is no way to predict if the Federal Reserve will have the courage to continue its very aggressive course of planned rate increases and balance-sheet reductions. If it follows through, interest rates should rise across the board. In the last tightening cycle beginning in 2015, the 10-year TIPS real yield rose as high as 1.17% in November 2018. In response, the Treasury set a fixed rate of 0.5% for the I Bond at both the May and November 2018 resets.
The first tick higher in the last tightening cycle came in November 2015, when the I Bond’s fixed rate increased to 0.1%. At that time the 10-year TIPS was yielding 0.63%.
We’ve got a ways to go, but if 10-year real yields rise anywhere close to 0.50% later this year, a higher fixed rate will be possible at the November 2022 reset. This would be positive for I Bond investors, because that fixed rate will continue into January 2023, when the purchase-limit clock resets.
But one more thing to consider: If you see 5- and 10-year TIPS real yields rise well above zero, you need to start considering TIPS as an investment. They will likely have a yield advantage over I Bonds for the first time in nearly three years.
