Treasury Inflation-Protected Securities (TIPS) Explained (2023)

What Are Treasury Inflation-Protected Securities (TIPS)?

Treasury inflation-protected securities (TIPS) are a type of Treasury security issued by the U.S. government. TIPS are indexed to inflation in order to protect investors from a decline in the purchasing power of their money.

As inflation rises, rather than their yield increasing, TIPS instead adjust in price (principal amount) in order to maintain their real value.

Key Takeaways

  • Treasury Inflation-Protected Security (TIPS) is a Treasury bond that is indexed to an inflationary gauge to protect investors from the decline in the purchasing power of their money.
  • The principal value of TIPS rises as inflation rises while the interest payment varies with the adjusted principal value of the bond.
  • The principal amount is protected since investors will never receive less than the originally invested principal.

Understanding Treasury Inflation-Protected Securities (TIPS)

The principal value of TIPS rises as inflation rises. Inflation is the pace at which prices increase throughout the U.S. economy, as measured by the Consumer Price Index (CPI). Inflation becomes an issue when there isn't a commensurate rise in real wage growth to offset the negative effects of rising prices.

TIPS are a popular asset for both protecting portfolios from inflation as well as profiting from it because they pay interest every six months based on a fixed rate determined at the bond's auction. However, the interest payment amounts can vary since the rate is applied to the adjusted principal or value of the bond. If the principal amount is adjusted higher over time due to rising prices, the interest rate will be multiplied by the increased principal amount. As a result, investors receive higher interest or coupon payments as inflation rises. Conversely, investors will receive lower interest payments if deflation occurs.

TIPS are issued with maturities of five, 10, and 30 years and are considered a low-risk investment because the U.S. government backs them. At maturity, TIPs return the adjusted principal or the original principal, whichever is greater.

TIPS can be purchased directly from the government through the Treasury-direct system, in $100 increments with a minimum investment of $100, and are available with 5-, 10-, and 30-year maturities.

Some investors prefer to get TIPS through a TIPS mutual fund or exchange-traded fund (ETF). Purchasing TIPS directly, however, allows investors to avoid the management fees associated with mutual funds.

In late 2021 into 2022, inflation fears have increased in the U.S. As a result, investors have begun to move into TIPS at an increasing pace.

TIPS' Price Relationship to Inflation

TIPS are important since they help combat inflation risk that erodes the yield on fixed-rate bonds. Inflation risk is an issue because the interest rate paid on most bonds is fixed for the life of the bond. As a result, the bond's interest payments might not keep up with inflation. For example, if prices rise by 3% and an investor's bond pays 2%, the investor has a net loss in real terms.

TIPS are designed to protect investors from the adverse effects of rising prices over the life of the bond. Thepar value—principal—increases with inflation and decreases with deflation, as measured by the CPI. When TIPS mature, bondholders are paid the inflation-adjusted principal or original principal, whichever is greater.

Suppose an investor owns $1,000 in TIPS at the end of the year, with a coupon rate of 1%. If there is no inflation as measured by the CPI, the investor will receive $10 in coupon payments for that year. If inflation rises by 2%, however, the $1,000 principal will be adjusted upward by 2% to $1,020. The coupon rate will remain the same at 1%, but it will be multiplied by the adjusted principal amount of $1,020 to arrive at an interest payment of $10.20 for the year.

Conversely, if inflation were negative, known as deflation, with prices falling 5%, the principal would be adjusted downward to $950. The resulting interest payment would be $9.50 over the year. However, at maturity, the investor would receive no less than the principal amount invested of $1,000 or an adjusted higher principal, if applicable.

The interest payments during the life of the bond are subject to being calculated based on a lower principal amount in the event of deflation, but the investor is never at risk of losing the original principal if held to maturity. If investors sell TIPS before maturity in the secondary market, they might receive less than the initial principal.

How to Buy TIPS

As with other Treasury securities, investors can buy TIPS directly from the U.S. government at the Treasury website This entails a somewhat complicated login process with several security layers.

You can also buy TIPS directly from your bank or broker. This may be more convenient for those investors who already have a substantial portfolio of securities at a certain financial institution.

Advantages and Disadvantages of TIPS

While TIPS are an attractive prospect for investors who expect high levels of inflation, they are at a disadvantage to other types of debt during periods of ordinary inflation. Below are some other considerations to keep in mind:

  • Lower Yield: TIPS usually pay lower interest rates than other government or corporate securities, so they are not necessarily optimal for income investors. Their advantage is mainly inflation protection, but if inflation is minimal or nonexistent, their utility decreases.
  • Tax Considerations: Like other Treasury bonds, the interest and inflation adjustments on TIPS are exempt from state and local income taxes. However, the inflation adjustment is considered taxable income by the IRS, even though investors don't see that money until they sell the bond or it reaches maturity. Some investors hold TIPS in tax-deferred retirement accounts to avoid tax complications. However, it may be worth contacting a tax professional to discuss any potential tax ramifications of investing in TIPS.


  • The principal increases with inflation meaning that at maturity, bondholders are paid the inflation-adjusted principal

  • Investors will never be paid less than their original principal when TIPS mature

  • Interest payments increase as inflation increases since the rate is calculated based on the adjusted principal balance


  • Interest rate offered is usually lower than most fixed-income bonds that do not have an inflation adjustment

  • Investors might be subject to higher taxes on increased coupon payments

  • If inflation does not materialize while TIPS are held, the utility of holding TIPS decreases

Example of TIPS

Below is a comparison of the 10-year TIPS as compared to the 10-year Treasury note, both issued and auctioned by the U.S. Treasury Department. Treasury notes (T-Notes) are intermediate-term bonds maturing in two, three, five, seven, or 10 years. They provide semiannual interest payments at fixed coupon rates.

As a historical example, on March 29, 2019, the 10-year TIPS was auctioned with an interest rate of0.875%. On the other hand, the 10-year Treasury note was auctioned March 15, 2019, with an interest rate of2.625% per year.

We can see that the 10-year note pays more interest (meaning that investors will receive higher coupon payments from the 10-year note as compared to the TIPS investment). However, if inflation rises, the principal on the TIPS will increase, allowing for the coupon payments to rise while the 10-year note is fixed for the life of the bond. Although TIPS protect against inflation, the offset is typically a lower yield than bonds with similar maturities.

How Can I Buy Treasury TIPS?

You can buy TIPS directly from the U.S. Treasury's TreasuryDirect website, with a minimum purchase of $100. You can also typically buy them through your broker. There are also several mutual funds and ETFs that invest in TIPS and other inflation-linked securities that you can buy and sell like ordinary shares of stock.

Can I Buy TIPS for My IRA?

Yes. You can include TIPS and funds that hold TIPS in an individual retirement account; however, you cannot use the TreasuryDirect service to buy them directly in an IRA. Instead, you would need to rely on the broker holding your retirement account.

What Yields Do TIPS Have?

Often the yields on TIPS are negative. This is because after taking into account the effects of inflation, the real yield is negative. For instance, if standard 2-year Treasuries yield 1% but inflation is 2%, then the real yield is -1%. TIPS are meant to keep up with inflation, not beat inflation, thus you can have a nominal yield on TIPS that is positive but a real yield that is effectively zero. Note that while the yield on TIPS may be negative, their principal value will increase with inflation, which can generate capital gains.

Why Does the Treasury Issue TIPS?

TIPS first appeared in 1997, and the official reason for their appearance is that there was strong demand from the investing public for inflation-linked government securities. Some economists, however, have been puzzled by the government's continued issuance of TIPS since they amount to a more expensive way to borrow than traditional Treasuries.

What Maturities Do Treasury TIPS Come in?

The original TIPS were set at 20 years maturity. In 2009, 20-year TIPS were discontinued in favor of 30-year TIPS. The U.S. Treasury presently issues 5-year, 10-year, and 30-year TIPS.

The Bottom Line

Treasury Inflation-Protected Securities (TIPS) are among the many types of debt securities offered by the U.S. Treasury Department. But unlike ordinary Treasury bonds, TIPS are designed to protect investors from inflation by adjusting the value of the principal as consumer prices rise.
