How Do TIPS Protect My Money From Inflation?
Last reviewed: July 2026
Treasury Inflation-Protected Securities, or TIPS, protect your money from inflation by adjusting their principal value up and down with the Consumer Price Index. When inflation rises, the bond's principal grows, and because your interest payment is calculated on that adjusted principal, your interest income grows too. TIPS inflation protection works because the government effectively rewrites the value of your bond to match the cost of living, so a dollar invested keeps its buying power even when prices climb.
Key Takeaways
- TIPS adjust their principal twice a year based on the Consumer Price Index, so your purchasing power stays intact when prices rise.
- According to TreasuryDirect, TIPS are sold in 5-, 10-, and 30-year terms and pay interest every six months.
- The current 10-year TIPS real yield is roughly 2.0% as of June 2026, meaning a guaranteed return above inflation.
- TIPS held in taxable accounts trigger "phantom income" tax on principal growth you have not yet received in cash.
- TIPS work best inside tax-deferred accounts like IRAs, where the annual tax drag disappears.

Jeff often reminds clients that TIPS are not a "set it and forget it" investment. Where you hold them matters almost as much as whether you hold them at all.
Inflation is the quiet thief in a financial plan. You don't see it on a statement, but it eats away at every dollar you've saved. TIPS are one of the few investments designed specifically to fight back. Let's walk through how they work, when they make sense, and the traps that catch most do-it-yourself investors.
What Are Treasury Inflation-Protected Securities and How Do They Work?
Treasury inflation-protected securities are U.S. government bonds whose principal rises and falls with inflation. The mechanism is simpler than the name suggests. You buy a TIPS at a face value, say $1,000. Twice a year, the Treasury adjusts that principal based on the Consumer Price Index for All Urban Consumers (CPI-U), which the Bureau of Labor Statistics publishes monthly. If inflation runs 3% over a year, your principal grows to roughly $1,030.
Here's the part that does the real work. Your interest rate is fixed, but it's applied to the adjusted principal. So as inflation pushes the principal higher, your dollar interest payments climb with it. You're earning a fixed rate on a growing balance. At maturity, you receive the inflation-adjusted principal or your original principal, whichever is greater. That floor matters during deflation: you can never get back less than what you put in.
TIPS come in 5-, 10-, and 30-year maturities and pay interest every six months, according to TreasuryDirect. You can buy them directly from the government at auction with no fee, or through a brokerage, mutual fund, or ETF. This is straightforward treasury inflation protected securities territory, backed by the full faith and credit of the U.S. government, which makes them one of the lowest-default-risk assets available.
How Do TIPS Compare to Regular Treasury Bonds?
The cleanest way to see the difference is to put a regular Treasury next to a TIPS side by side. A nominal Treasury pays a stated rate and returns a fixed dollar amount. A TIPS pays a lower stated rate but adjusts the principal for inflation. The gap between the two yields is called the "breakeven inflation rate," and it tells you what the market expects inflation to average over the bond's life.
| Feature | Nominal Treasury | TIPS |
|---|---|---|
| Principal at maturity | Fixed dollar amount | Adjusted for inflation |
| Interest rate | Higher stated rate | Lower stated (real) rate |
| Inflation protection | None | Built in |
| Deflation protection | None needed | Original principal floor |
| Best when | Inflation falls below expectations | Inflation runs higher than expected |
The decision comes down to a bet on inflation. If actual inflation exceeds the breakeven rate, TIPS win. If it comes in lower, the nominal bond wins. As of June 2026, the 10-year breakeven inflation rate sits near 2.3%, meaning the market expects inflation to average about that much over the next decade. Jeff Judge tells clients not to treat this as a forecasting contest. The point of a TIPS isn't to outguess the market. It's to remove inflation as a variable you have to worry about at all.

Are TIPS a Good Inflation Hedge for My Portfolio?
TIPS are a strong inflation hedge for the portion of your portfolio you cannot afford to lose to rising prices, but they are not a magic shield for everything. Their value lies in protecting purchasing power on safer money: an emergency reserve beyond cash, a near-term retirement income bucket, or money earmarked for a goal five to ten years out.
What TIPS do not do is grow wealth aggressively. The real yield is modest by design. Right now the 10-year TIPS real yield is around 2.0% as of June 2026, which is a guaranteed return above inflation but well below what stocks have historically delivered. So a 30-year-old saving for retirement gains little from loading up on TIPS. A 64-year-old building a five-year spending bridge into retirement gains a lot.
This fits the broader logic of matching investments to your time horizon. As your goals get closer, the right mix shifts away from growth and toward protection. See How should my investment mix change as I get closer to retirement? for how that progression works decade by decade. TIPS are most useful as one tool in a diversified plan, not the whole plan.

What Are the Tax Traps With TIPS?
The biggest TIPS trap has nothing to do with markets. It's taxes, and it catches almost every first-time buyer. When the Treasury adjusts your principal upward for inflation, the IRS treats that increase as taxable income in the year it happens, even though you don't receive the cash until the bond matures. This is called "phantom income." You owe tax on money you haven't actually been paid yet.
In a high-inflation year, this can sting. Imagine inflation pushes your TIPS principal up by $900. You'll owe federal income tax on that $900 now, with no cash in hand to cover the bill. Jeff has watched clients buy TIPS in a regular brokerage account, feel good about the inflation protection, and then get blindsided at tax time. The fix is simple: hold TIPS inside a tax-deferred account like a traditional IRA or 401(k), where the phantom income problem disappears entirely. There you let the principal grow without an annual tax drag, and you only pay tax when you withdraw.
One bright spot. TIPS interest and inflation adjustments are exempt from state and local income tax, which helps residents of higher-tax states. But for most investors, the account-placement rule is the one that matters. Where you hold a TIPS can change its after-tax return more than the bond itself.
Frequently Asked Questions
How exactly do TIPS protect against inflation?
TIPS protect against inflation by adjusting their principal value with the Consumer Price Index twice a year. When prices rise, the principal grows, and because your fixed interest rate applies to that larger principal, your interest payments grow too. At maturity you receive the higher of the adjusted or original principal.
Are TIPS a better inflation hedge than I Bonds?
TIPS and I Bonds both hedge inflation, but they serve different needs. I Bonds limit you to $10,000 per person per year and must be held at least one year, while TIPS have no purchase limit and trade freely on the secondary market. TIPS suit larger sums and tax-deferred accounts; I Bonds suit smaller annual savings.
Can I lose money with TIPS?
Yes, you can lose money with TIPS in the short term if you sell before maturity and interest rates have risen, since the bond's market price drops. If deflation occurs, your principal can fall during the term, but at maturity you are guaranteed to receive at least your original principal. Held to maturity, your purchasing power is protected.
Where should I hold TIPS to avoid the tax problem?
You should hold TIPS inside a tax-deferred account like a traditional IRA or 401(k) to avoid the phantom income tax. In those accounts, the annual tax on inflation-driven principal growth disappears, and you only pay tax when you withdraw funds. Holding TIPS in a taxable brokerage account triggers tax on gains you have not yet received in cash.
How do I buy TIPS?
You can buy TIPS three ways: directly from the government at auction through TreasuryDirect.gov with no fees, through a brokerage account on the secondary market, or through a TIPS mutual fund or ETF. Funds offer instant diversification across maturities but charge an expense ratio. Buying individual TIPS lets you control the exact maturity date.
Do TIPS make sense for a long-term retirement portfolio?
TIPS make sense for the protective portion of a retirement portfolio, especially within five to ten years of needing the money. For younger investors decades from retirement, the modest real yield offers little compared to stocks. TIPS work best as one piece of a diversified plan matched to your time horizon, not as a growth engine.
Inflation will keep nibbling at your savings whether you plan for it or not. TIPS inflation protection gives you one reliable way to draw a line under part of your money and say prices can't touch this.
