TIPS Can Help Investors When Inflation Spikes

Rising inflation may leave investors wondering whether they should keep fixed income out of their portfolios, but history shows Treasury Inflation-Protected Securities (TIPS) can be a useful tool to hedge against inflation.1

TIPS vs. Inflation

TIPS outperformed inflation2 in 72% of the rolling, overlapping 12-month periods from 2001 to 20213 (see Exhibit 1).4 Put another way, TIPS helped investors preserve their purchasing power in nearly three out of four of the 252 rolling one-year periods over this 20-year span, according to Dimensional research.

Here’s a TIP

Past performance is not a guarantee of future results. Indices are not available for direct investment; therefore, their performance does not reflect the expenses associated with the management of an actual portfolio.

However, like all bonds, TIPS can be affected by changes in interest rates. When rates rise, the prices of existing bonds fall as new bonds issued with higher rates become more attractive. That means the total return of an inflation-protected security can be higher or lower than the annual inflation adjustment.

Still, for investors determined to protect their purchasing power as inflation rises, TIPS can be an effective option.


  1. 1The principal of a TIPS increases with inflation and decreases with deflation, as measured by the Consumer Price Index. When a TIPS matures, investors are paid the adjusted principal or original principal, whichever is greater. TIPS pay interest twice a year, at a fixed rate. The rate is applied to the adjusted principal; that means interest payments, like the principal, rise with inflation and fall with deflation.

Risks include loss of principal and fluctuating value. Fixed income securities are subject to increased loss of principal during periods of rising interest rates, and they are subject to various other risks, including changes in credit quality, liquidity, prepayments, and other factors. Inflation-protected securities may react differently from other debt securities to changes in interest rates.
