Inflation doesn’t announce itself politely. It just quietly makes your savings worth less every year, and by the time most people notice, they’ve already lost ground they can’t easily get back. If you’re looking for a genuine inflation hedge backed by the U.S. government, two options come up again and again: I Bonds and Treasury Inflation-Protected Securities, better known as TIPS.
Both are backed by the full faith and credit of the U.S. Treasury. Both are designed as wealth preservation tools built specifically to protect your purchasing power. And both get lumped together constantly, as if they’re interchangeable. They’re not. The differences between I Bonds vs TIPS matter enormously depending on how much you’re investing, how long you can leave it untouched, and what tax situation you’re in.
What Both of These Actually Are
Before comparing them, it helps to understand what each one is doing mechanically, because the two work in genuinely different ways.
I Bonds (Series I Savings Bonds) pay a composite rate made up of two parts: a fixed rate that stays the same for the entire life of the bond, and a variable rate that resets every six months based on inflation. You buy them directly from the U.S. Treasury through TreasuryDirect.gov, there’s no secondary market, and no way to sell them to another investor.
Treasury Inflation-Protected Securities (TIPS) work differently. Instead of adjusting the interest rate, TIPS adjust the principal value of the bond itself to keep pace with inflation, while paying a fixed coupon rate on that adjusted principal. Unlike I Bonds, TIPS trade on the open secondary market, so you can buy and sell them before maturity, and you can also hold them inside a regular brokerage account or an IRA.
US Treasury Inflation-Protected Securities: The Numbers Right Now (2026)
This is where most comparisons go stale fast, since both rates change regularly. Here’s where things actually stand:
I Bonds issued from May through October 2026 carry a composite rate of 4.26%, combining a 0.90% fixed rate with a 3.34% inflation-adjusted variable rate. That fixed portion of 0.90% is locked in for the entire life of the bond, up to 30 years, regardless of what happens to inflation afterward. Only the variable portion resets every six months.
Treasury Inflation-Protected Securities are priced differently across maturities. As of mid-July 2026, the 10-year TIPS real yield sits around 2.29-2.33%, the 5-year around 1.91%, and the 30-year around 2.85%. Because TIPS trade on the open market, these numbers move daily along with broader interest rate conditions, unlike an I Bond’s fixed rate, which is locked at the moment of purchase.
On the surface, TIPS yields look lower than the I Bond composite rate. But that comparison isn’t quite fair, because the I Bond rate already includes an inflation estimate baked into the variable portion, while the TIPS real yield is separate from inflation by design, inflation gets added on top through principal adjustments. The genuinely comparable number is the fixed portion of each: I Bonds currently lock in 0.90% above inflation for the life of the bond, while 10-year TIPS lock in roughly 2.29% above inflation. On that specific measure, TIPS are currently offering a meaningfully higher guaranteed real return than new I Bonds.
Where I Bonds Win
Purchase limits work in your favor if you’re investing small amounts. I Bonds cap purchases at $10,000 per person per calendar year through TreasuryDirect (with an additional $5,000 possible via tax refund). If you’re building an inflation hedge gradually rather than deploying a large lump sum, the same steady, low-friction approach that makes sense when choosing between apps like Wise, Revolut, or N26 for moving money efficiently, this isn’t really a limitation.
No price volatility. Because I Bonds don’t trade on a secondary market, their value only moves in one direction: up, as interest accrues. Treasury Inflation-Protected Securities, by contrast, can lose market value before maturity if real yields rise, you won’t lose your inflation adjustment, but the bond’s price can still dip if you need to sell early.
State and local tax exemption. Interest from both I Bonds and TIPS is exempt from state and local income tax, but I Bonds go a step further: you can defer federal tax on the interest until you cash the bond in, for up to 30 years, useful if you expect to be in a lower tax bracket later, such as in retirement.
A genuine floor against deflation. The composite rate on an I Bond can never drop below 0%, even in a deflationary environment. That’s a real guarantee that protects your principal in a way few other instruments do.
Where Treasury Inflation-Protected Securities (TIPS) Win
No annual purchase limit. This is the single biggest practical difference. If you have a meaningful amount of capital you want to protect from inflation , well beyond the $10,000 I Bond cap, TIPS simply don’t have that ceiling.
Currently higher locked-in real yield. As of 2026, the fixed real return on 10-year Treasury Inflation-Protected Securities is more than double the fixed rate on newly issued I Bonds. If you’re comparing pure guaranteed return above inflation, TIPS are ahead right now.
Liquidity. You can sell TIPS on the secondary market whenever you need to, without waiting a mandatory holding period. I Bonds can’t be redeemed at all for the first 12 months, and redeeming before 5 years costs you the last 3 months of interest.
Accessible through retirement accounts. TIPS can be held inside an IRA or 401(k), letting you shelter the inflation-adjusted interest from current taxation entirely, a flexibility I Bonds don’t offer, since I Bonds must be purchased directly and held individually.

The Tax Detail Most Comparisons Skip
This one catches people off guard. With TIPS held in a regular taxable brokerage account, you owe federal income tax each year on the inflation adjustment to the principal, even though you don’t actually receive that money until the bond matures or you sell it. This is sometimes called “phantom income,” and it’s a real drawback for Treasury Inflation-Protected Securities held outside a tax-advantaged account.
I Bonds don’t have this problem. All the interest, both the fixed and inflation-adjusted portions, accumulates without any tax owed until you actually cash the bond in. For investors holding these in a regular taxable account rather than an IRA, this difference alone can matter more than the headline rate.
Gold, TIPS, or I Bonds? How This Fits Into Broader Wealth Preservation Strategies
I Bonds and TIPS aren’t the only government-backed or inflation-linked options on the table, gold is the other name that comes up constantly in any conversation about wealth preservation strategies. The short version: gold has no yield and no government guarantee, but it isn’t subject to any purchase limit, doesn’t rely on U.S. Treasury policy, and tends to behave differently during currency devaluation scenarios where TIPS and I Bonds, despite being inflation-linked, are still ultimately dollar-denominated. For most people building a genuinely inflation-resistant portfolio, I Bonds and TIPS form the reliable, low-volatility core, while a smaller allocation to gold or other real assets adds a layer of protection against risks that inflation-linked Treasury securities don’t fully cover.
So Which One Should You Actually Use?
Neither one is a universal winner, they solve different problems.
- Choose I Bonds if: you’re investing a modest, steady amount each year (under the $10,000 cap), want to avoid any tax complexity in a taxable account, and value the guarantee that your bond will never lose nominal value.
- Choose Treasury Inflation-Protected Securities if: you have a larger amount to protect from inflation, want the flexibility to buy and sell before maturity, or can hold them inside an IRA or 401(k) where the annual phantom income tax issue disappears entirely.
- Consider both if: you want to maximize your I Bond allocation up to the $10,000 annual limit as your inflation-protected “base,” then use TIPS inside a retirement account for any additional inflation hedging beyond that.
Finanlytic Takeaway
FINANLYTIC | DATA INTELLIGENCE UNIT | Analysis by Hugo | Lead Market Strategist
I Bonds vs TIPS isn’t really a competition, it’s a question of amount, timeline, and account type. For most people just starting to build real wealth preservation strategies, maxing out the I Bond limit each year is the simplest, lowest-friction move: no market volatility, no tax headaches in a taxable account, and a real return that’s currently attractive at 4.26%. Once you’ve done that and still have more you want to protect, Treasury Inflation-Protected Securities, ideally inside an IRA, is where that additional protection should go.
The mistake to avoid is treating either one as a full investment strategy on its own. Both are inflation insurance, not growth engines. They’re the ballast in a portfolio, not the sail.
