I Bonds were unquestionably a better deal in 2022 than they are today, and the numbers tell a stark story. In May 2022, newly issued I Bonds carried a 9.62% composite interest rate—the highest rate since the Treasury introduced I Bonds in 1998. An investor who bought a $10,000 I Bond in May 2022 would earn $481 in interest over the first six months alone, compared to just $213 today. The difference isn’t marginal; it’s the gap between a historically exceptional investment and a merely acceptable one.
The reason for this dramatic drop is straightforward: inflation has moderated substantially since 2022’s crisis peak. In June 2022, consumer prices had climbed 9.1% year-over-year—the highest level in over forty years. I Bonds, by design, move with inflation. When inflation was at its worst, I Bonds delivered historically unprecedented yields. Now, with inflation closer to the Fed’s 2% target, I Bond rates have retreated accordingly to 4.26% as of May 2026, representing a 56% decline from the 2022 high.

What Made 2022’s I Bond Rates So Extraordinary?
To understand why 2022 was special, you need to recognize that I Bonds have rarely offered rates anywhere near 9.62%. This wasn’t a marketing gimmick or a limited-time offer—it was a direct consequence of the inflationary environment. The I Bond rate resets every six months based on actual CPI data. In 2022, when the Consumer Price Index spiked to its highest level since 1981, the Treasury simply had to offer higher rates to make I Bonds competitive with other savings options. The 9.62% rate that applies to bonds issued between May and October 2022 consisted entirely of an inflation adjustment. There was no fixed rate component—zero percent.
This meant that while the initial yield was spectacular, it would adjust downward as inflation moderated. An I Bond purchased in May 2022 would see its rate reset to a lower figure six months later, then reset again six months after that. Despite these future reductions, the opportunity to lock in that initial 9.62% for six months was genuinely rare and valuable. Compare this to the current environment. Today’s 4.26% rate still includes an inflation component that adjusts twice yearly, but it also includes a 0.90% fixed-rate component that stays with the bond for its entire 30-year life. This fixed portion is nearly three times higher than it was in 2022 (when it was 0%), but it still doesn’t come close to making up for the loss of nearly 5.4 percentage points in inflation adjustment.
How I Bond Rates Actually Work—and Why Timing Mattered
I Bonds have a structure that many investors misunderstand, and that structure explains why 2022 was so valuable. Each I Bond has two components: a fixed rate set at purchase and an inflation rate that adjusts every six months. The composite rate is simply the sum of these two. The fixed rate never changes; it’s locked in for the life of the bond. The inflation rate, however, fluctuates based on the latest Consumer Price Index data. In 2022, the Treasury set the fixed rate at 0% for new purchases. This was an aggressive move—it essentially meant the Treasury was confident that inflation would eventually moderate, so they weren’t willing to offer any permanent return.
All the return would come from the inflation adjustment. That worked out brilliantly if you were buying during the peak inflation months, because that inflation adjustment was enormous. But it also meant that as inflation fell, your bond’s yield would fall with it. Today’s bonds have a 0.90% fixed rate, which provides a safety net of sorts. If inflation falls below 0.90%, your I Bond will still yield 0.90% (because the inflation component of the rate can’t go below zero). However, this comes with a warning: you’re essentially betting that inflation will stay relatively stable or potentially rise. In a low-inflation environment, that 0.90% fixed rate might be the best return you see on your I Bond for years.
The Historical Context—Why 2022 Was a Rare Perfect Storm
To truly grasp why 2022 was a better deal, you need to understand what made that year so unusual. The inflation of 2022 wasn’t a gradual creep upward; it was a sharp shock. Pandemic-era supply chain disruptions, aggressive fiscal stimulus, and historically low interest rates created a perfect storm of rising prices. The CPI jumped 9.1% year-over-year in June 2022—the worst reading in over forty years. This inflationary spike forced the Federal Reserve to act aggressively, raising interest rates rapidly to cool the economy. As the Fed tightened policy through late 2022 and into 2023, inflation began to come down. By early 2024, inflation had fallen back below 3%.
By 2025, it was moving closer to the Fed’s 2% target. This moderation was exactly what the Treasury had implicitly predicted when they set the fixed rate at 0% in 2022—they were betting that high inflation wouldn’t last, and they were right. An investor who recognized this timing opportunity in 2022 made a brilliant decision. They bought I Bonds with the knowledge that they were capturing an exceptional rate during an exceptional moment. They didn’t know exactly when inflation would fall, but they knew it would eventually. And when it did, they’d be holding a six-month position that had locked in the peak rate. It was a rare convergence of circumstances: maximum inflation, maximum I Bond yield, and a temporary opportunity window.
I Bonds in 2022 vs. 2026—The Numbers Don’t Lie
Let’s put this in concrete terms. Suppose you bought a $10,000 I Bond in May 2022. For the first six months, you’d earn 9.62% annualized, which translates to about $481 in interest. Six months later, when the rate reset, your return would be lower—perhaps 7% or 8% depending on inflation. Over the full first year, you might earn roughly $800 to $900 in interest, depending on exactly when you purchased and how the rate reset. Fast forward to today. A $10,000 I Bond purchased now earns 4.26% annualized, or about $213 over the first six months.
Over the full first year, assuming the rate stays the same (it won’t, but let’s keep it simple), you’d earn roughly $426. The 2022 bond yields roughly double what a 2026 bond yields, at least in the early period. Over a full 30-year life, the compounding effect would make this difference even more pronounced. A 2022 bond that averaged perhaps 6% over its lifetime would significantly outperform a 2026 bond that might average 3.5% to 4%. This comparison isn’t meant to suggest that today’s I Bonds are a bad investment. A 4.26% rate is still reasonable in a low-inflation environment, and the 0.90% fixed component provides some downside protection. But it clearly illustrates why anyone with the foresight to purchase in 2022 made a superior financial decision.
The Fixed-Rate Trap and What It Means Going Forward
One important limitation that many I Bond investors overlook is the impact of that zero fixed rate in 2022. You got a spectacular initial return, but you also locked in zero growth during any low-inflation periods. An I Bond purchased in May 2022 will eventually reach a period where inflation is very low—perhaps 1% or 1.5%. At that point, your bond’s rate will be just 1% to 1.5% because the fixed rate was 0%. Compare this to a bond purchased today. The 0.90% fixed rate means your bond will never yield less than 0.90%, even if inflation falls to near zero. This is actually a valuable feature that 2022 buyers didn’t get.
It’s a reminder that exceptional rates in one period often come with tradeoffs in other periods. The 2022 investor got higher initial returns but gave up a floor. The 2026 investor is trading higher current returns for downside protection. There’s also a warning for anyone looking at older I Bonds. If you have bonds from the late 2010s, before the inflation spike, they likely have a low fixed rate (or even negative rates in some cases). Those bonds never recovered to anywhere near 9.62% even at the peak of inflation. This reinforces why 2022 was truly special—the combination of high inflation and a low fixed rate was a one-time event.
The Real-World Impact—What 2022 Investors Actually Captured
Let’s make this tangible. Sarah, a conservative investor, recognized the opportunity in May 2022 and invested $50,000 in I Bonds. Her first-year interest earnings, based on the rate structure, would be approximately $4,500 to $4,750.
If she had invested the same $50,000 in newly issued I Bonds in May 2026 instead, her first-year earnings would be roughly $2,150 at today’s 4.26% rate. That’s a difference of more than $2,000 in the first year alone. Over the 30-year life of the bonds, if 2022 inflation rates gradually settle to around 2% on average (implying an overall bond yield of around 2% for most of the bond’s life after the initial period), and 2026 bonds average around 2.9% (the fixed 0.90% plus long-term average inflation of around 2%), the 2022 bond might generate roughly $50,000 more in total interest over its lifetime. That’s not a small difference, and it all stems from the circumstance of buying during the peak inflation moment.
Looking Ahead—Are I Bonds Worth Buying Now?
The fact that 2022 was a better deal doesn’t mean I Bonds are worthless today. A 4.26% rate in May 2026 is still superior to what you’d get from a high-yield savings account earning 4.0%, and it comes with the advantage of a 0.90% fixed floor that protects against deflation. If inflation were to spike again—due to geopolitical disruption, energy shocks, or other unforeseen circumstances—your I Bond purchased today could see its rate climb significantly in the next adjustment period.
The key takeaway is that I Bonds are most attractive when inflation is high and rising, and least attractive when inflation is low and stable. 2022 was arguably the most attractive moment for I Bonds in a generation. Today, they’re a reasonable holding for conservative investors and those concerned about inflation risk, but they’re not the exceptional opportunity they were four years ago. As you consider whether to purchase I Bonds now, recognize that you’re likely not capturing a one-time deal—you’re making a prudent but conventional investment choice.
Conclusion
I Bonds in 2022 were a better deal than they are today, plain and simple. The 9.62% composite rate of May 2022 was historically unprecedented, reflecting an inflationary environment that was itself unprecedented in over forty years. Today’s 4.26% rate represents a 56% decline, driven by the moderation in inflation that everyone expected to happen eventually. Investors who recognized the opportunity in 2022 and acted on it made a genuinely excellent financial decision.
This doesn’t mean you’ve missed your chance to benefit from I Bonds or that current rates are unattractive. It simply means that you were competing against one of the most favorable rate environments in the modern history of Treasury securities. If you’re considering I Bonds today, evaluate them on their merits as a current investment—competitive with other safe assets, carrying inflation protection, and offering a reasonable return in a stable economic environment. But understand that the 2022 experience was rare, and comparing today’s reality to that exceptional moment will only lead to disappointment.
