Treasury Inflation-Protected Securities (TIPS) are specialized government bonds designed to shield investors from inflation’s eroding effects on purchasing power. Issued by the U.S. Treasury since 1997, TIPS uniquely adjust both their principal and interest payments based on changes in the Consumer Price Index for All Urban Consumers (CPI-U), which measures inflation and deflation in the economy.
How TIPS Work
TIPS principal is adjusted semiannually according to the latest CPI-U data. If inflation rises, your bond’s principal increases. Conversely, during deflationary periods, the principal decreases but never falls below the original par value at maturity, protecting your initial investment.
The interest rate on TIPS is fixed at purchase, but it is applied to the inflation-adjusted principal, resulting in increased interest payments when inflation is positive and decreased payments during deflation. Interest is paid twice a year, and at maturity, investors receive the greater of the adjusted principal or the original par value.
Historical Context
Before TIPS, investors risked losing purchasing power with traditional bonds during periods of inflation when the fixed interest failed to keep pace with rising prices. The introduction of TIPS provided a reliable inflation hedge, especially beneficial for retirees or long-term savers focused on preserving the real value of their capital.
Investment Considerations
TIPS are especially suitable for individuals seeking:
- Inflation protection for income and principal
- Low default risk backed by the U.S. government
- A tool to diversify fixed-income portfolios
However, they tend to offer lower nominal interest rates compared to traditional Treasury bonds during low-inflation periods, reflecting the value of built-in inflation protection.
Tax Implications
Investors should be aware that the inflation adjustment to TIPS principal is taxable in the year it occurs, even though it is not received until maturity or sale. This “phantom income” can increase an investor’s tax liability on a TIPS held in taxable accounts. Many prefer holding TIPS in tax-advantaged accounts like IRAs or 401(k)s to defer taxation.
How to Invest in TIPS
- Direct Purchase: Buy new issues at auction or on the secondary market through TreasuryDirect.gov, which offers a cost-efficient route.
- Mutual Funds & ETFs: For diversification and liquidity, TIPS-focused funds and ETFs are popular options.
- Maturity Matching: Selecting TIPS with maturities aligned to your financial goals can reduce interest rate risk.
Comparing TIPS to Other Investments
TIPS differ from traditional Treasury bonds and corporate bonds by providing direct inflation adjustment, which protects real returns. Although stocks may also provide inflation protection over time, they come with higher volatility and risk. For low-risk inflation hedging, TIPS provide a uniquely government-guaranteed option.
Common Misconceptions
- Not Risk-Free: While default risk is very low, TIPS have interest rate risk and can lose value if sold before maturity.
- Phantom Income Surprise: The taxable inflation adjustments can catch investors off guard without proper planning.
- Performance Varies: TIPS excel mainly during higher inflation; in low or negative inflation environments, their returns may lag other investments.
