TIPS are issued at various times throughout the year and are sold in $100 increments. You can purchase TIPS through the U.S. Treasury website with maturities at auction of 5, 10 or 30 years. You can also purchase bonds with interim maturities through a bank or brokerage firm, or directly online. Certain mutual funds and exchange traded funds (ETFs) may also invest in TIPS, an approach that can provide tax advantages (see “Are TIPS bonds taxed?” below).
Key takeaways
Inflation has dropped recently but is still a factor, so it’s important to make sure your investments keep pace with living costs.
Treasury Inflation-Protected Securities, or TIPS, are fixed-income securities that provide inflation protection. TIPS premiums increase when the Consumer Price Index rises and decrease when the CPI falls.
It’s important to understand the risks and consult with a financial professional before investing in TIPS bonds.
Although it has declined significantly from peak levels, inflation remains much in the news. In the closing months of 2024, the headline Consumer Price Index (CPI) trended modestly higher, to just under 3% over the previous 12 months. In February 2025, President Donald Trump announced plans for expanded tariffs on goods from Mexico, Canada and China, raising concerns about potential inflation implications.
Inflation is a significant factor for investors who rely on a steady stream of income from bonds and other fixed-income instruments. Rising living costs can eat away at a bondholder’s purchasing power if income remains constant. Treasury Inflation Protected Securities (TIPS) were created to help at least partially address fixed income portfolios’ inflation risk.
Inflation’s effect on investment portfolios
Let’s take a minute to look at inflation in recent years. The cost of living, as measured by the Consumer Price Index (CPI), started to rise in 2021 and peaked in mid-2022. During that period, inflation far outpaced typical 10-year U.S. Treasury bond yields.1 Bond investors found their portfolios losing ground to inflation.
“For a long-term investor, TIPS can offer an opportunity for an investment that keeps pace with living costs. If there are inflation surprises down the road, TIPS investors will have a degree of protection.”

However, by mid-2023, inflation tapered off, and bond yields rose, putting fixed income investors in a more favorable position.1
Recent experience highlighted TIPS’ potential benefits. Because earnings from TIPS are essentially adjusted for inflation, TIPS investors saw income streams grow more significantly during the high inflation period. When inflation is more muted, income may rise, but not as significantly.
TIPS are issued by the U.S. government and, like other Treasury securities, are backed by the full faith and credit of the federal government. Unlike regular bonds, however, TIPS provide the potential to earn a total return that reflects inflation.
“For a long-term investor, TIPS can offer an opportunity for an investment that keeps pace with living costs,” says Rob Haworth, senior investment strategy director for U.S. Bank Wealth Management. “If there are inflation surprises down the road, TIPS investors will have a degree of protection.”
How TIPS bonds work
TIPS bonds account for inflation by adjusting the principal value of the security in line with the inflation rate. When CPI rises, the principal value of a TIPS bond also rises. If deflation occurs and CPI drops, the principal value of TIPS drops, too.
As an example, say you own a TIPS bond valued at $10,000 with a coupon of 2%. Based on the initial principal value of $10,000, you would see income of $200 for the year.
Now let’s look at what would happen in the case of inflation or deflation:
- Inflation: If CPI increases by 3%, the principal adjusts by the same percentage (adding $300 to your original principal). As a result, you receive 2% of $10,300 for the year, or $206.
- Deflation: If CPI declines 4%, the $10,000 principal on your TIPS bond readjusts to $9,600, and the 2% coupon pays income of $192. Historically, prices rarely decline on a year-to-year basis.
Note that the coupon rate (2%, in this example) remains constant, and changes in CPI do not affect the coupon rate. The inflation-adjusted principal value is not realized until the issue matures or is sold. At that time, the investor receives the higher of the adjusted principal value or the original principal value. You will never receive less than the original principal value.

How do interest rates affect TIPS bonds?
First, you should be aware that TIPS typically pay a lower yield than comparable Treasury securities. In essence, you trade off current yield for inflation protection.
In terms of the interest rate’s impact, Haworth notes that just as with other Treasury securities, TIPS are at a disadvantage when rates rise, or during periods of modest inflation.
“When interest rates are rising, prices of TIPS are subject to a loss in value just as is the case with other types of bonds,” he says. “The impact of inflation is still reflected in the price of TIPS, but they’re also subject to changes in the broader interest rate environment.”
As of early 2025, Haworth notes TIPS are generally competitive with Treasury securities. However, Haworth says investors may wish to consider other, non-government bond opportunities. “Another option to boost income is to look at more complex credits rather than investing in TIPS to protect against an inflation surprise,” says Haworth. “With vehicles like certain residential mortgage-backed securities, commercial mortgage-backed securities and collateralized loan obligations, you’ll earn more competitive income from the start.” Note that unlike TIPS, these complex credits are not backed by the full faith and credit of the U.S. government.
Opportunities and risks with TIPS
As you think about how TIPS might fit into your portfolio, it can be helpful to weigh the opportunities they provide along with the risks.
Opportunities with TIPS
- TIPS allow bond investors to achieve a degree of inflation protection not available in most other fixed-income investments.
- TIPS are backed by the full faith and credit of the U.S. government, meaning they have low credit risk.
- Both underlying principal and the income it generates can rise in line with the rate of inflation.
- At maturity, the principal value of TIPS will be no lower than your initial investment.
Risks with TIPS
- As with traditional bonds, the underlying value of TIPS can decline in times when interest rates are rising.
- In deflationary times, the value of TIPS and income generated from them will decline.
- Any appreciation in principal value is taxable even before you realize those gains.
These are also good talking points when meeting with a financial professional.
Frequently asked questions about TIPS bonds
“TIPS tend to perform best in periods when the interest rate environment is relatively stable but inflation is suddenly moving higher,” says Haworth. “In periods like these, the inflation adjustments in TIPS can provide some advantages.”
After a period of elevated prices, inflation recently dropped below 3%, closer to its long-term average. “In this environment, TIPS’ potential benefits are less evident,” says Haworth. He notes that given the recent yield environment, TIPS may look competitive with traditional government bonds.
Haworth says in today’s environment, investors seeking yield advantages may also consider non- government agency issued residential mortgage-backed securities, collateralized mortgage obligations (CMOs) or, where appropriate, reinsurance pools.
TIPS pay interest every six months until the bond’s maturity. The rate of interest is fixed and based on the underlying principal value. Since the principal value can change, the interest amount can change as well. This is unlike a conventional Treasury bond, which pay a constant income stream regardless of market or inflationary conditions.
Tax treatment of TIPS is a significant consideration. Interest payments from TIPS are subject to federal tax but are exempt from state and local taxes. In addition, if the principal value increases, the amount of that increase is taxable at the federal level in the year it occurs. “It’s best to own TIPS through a mutual fund or exchange traded fund (ETF),” says Haworth. “If you purchase TIPS directly, you’ll owe taxes on the imputed interest inflation adjustment.” This is an effect referred to as “phantom income.”
The inflation-adjusted principal value isn’t realized until the bond issue matures or you sell it. At that point, you would receive the adjusted principal value or the original principal value, whichever is higher.
You will never receive less from a TIPS bond than the original amount you paid for it.
TIPS Inflation Index Ratios2 are provided by the U.S. Treasury Department to help calculate the impact on bonds.
Since TIPS typically pay an interest rate that is lower than that offered by a comparable Treasury security, investors may not benefit from inflation protection if cost-of-living changes are minimal over the holding period.
Seek professional advice before investing in TIPS bonds
Before buying TIPS bonds, you should assess current inflation expectations or consider the degree of inflation protection you need in your fixed-income portfolio. A financial professional can help you determine if TIPS are a good fit for your investment portfolio.
