TIPS, Stocks, and Social Security as Inflation Shields

Full analysis

Adam Grossman of Mayport examines the real-world limits of Treasury Inflation-Protected Securities (TIPS — U.S. government bonds whose value rises with inflation) as a retirement inflation hedge. He notes that the attractive ~3% real yield on TIPS applies only to 30-year bonds; shorter maturities pay less, and individual TIPS are cumbersome to manage because aligning bond maturity dates to unpredictable future cash needs is difficult. TIPS funds are simpler but proved disappointing in 2022 — when inflation hit 9%, the Vanguard Inflation-Protected Securities Fund (VAIPX) lost nearly 12% because the Federal Reserve's aggressive rate hikes more than offset the inflation boost.

Grossman's practical recommendation for people already in or near retirement: favor a short-term TIPS fund such as Vanguard's VTIP over a broadly diversified TIPS fund, and pair it with two often-overlooked inflation defenses. First, delaying Social Security claiming — benefits rise with inflation and increase each year you wait, making it one of the most effective built-in inflation hedges available. Second, stocks, which have historically allowed companies to raise prices and protect profit margins during inflationary periods. He explicitly advises against gold, citing research that finds it an unreliable inflation hedge over practical investment horizons.
