Comparing I Bonds and Tips: Which Is the Better Inflation Hedge?

by

Investors seeking protection against inflation often compare I Bonds and Treasury Inflation-Protected Securities (TIPS). Both are designed to preserve purchasing power, but they have different features and benefits. Understanding these differences can help investors choose the best option for their financial goals.

I Bonds

I Bonds are savings bonds issued by the U.S. Treasury. They offer a fixed interest rate combined with an inflation-adjusted rate that changes twice a year. The inflation component is tied to the Consumer Price Index for All Urban Consumers (CPI-U). I Bonds are exempt from state and local taxes and can be purchased in denominations as low as $25.

One key feature of I Bonds is their tax deferral; taxes on the interest are not due until redemption or maturity. They also have a maximum purchase limit per year, which makes them suitable for small to moderate investments. I Bonds must be held for at least one year, and redeeming before five years results in a penalty of the last three months’ interest.

TIPS

TIPS are marketable securities issued by the U.S. Treasury. Their principal value adjusts with inflation based on the CPI-U, and interest is paid semiannually on the adjusted principal. TIPS can be purchased in the open market or directly through TreasuryDirect.

Unlike I Bonds, TIPS are subject to federal income tax on both the interest payments and the inflation adjustment each year, even if the investor does not sell the bond. They are more suitable for investors seeking a liquid, marketable security that can be bought and sold easily. TIPS do not have a purchase limit and can be part of a diversified investment portfolio.

Comparison and Suitability

Both I Bonds and TIPS provide inflation protection, but their differences influence their suitability for various investors. I Bonds are ideal for small investors seeking tax advantages and a safe, long-term savings option. TIPS are better suited for investors looking for liquidity and the ability to trade securities in the open market.

  • I Bonds have purchase limits; TIPS do not.
  • I Bonds are exempt from state and local taxes; TIPS are subject to federal taxes.
