Why TIPS Beat Regular Bonds for Long-Term Safe Money

Full analysis

Treasury Inflation-Protected Securities (TIPS) — U.S. government bonds whose principal automatically adjusts with actual inflation — offer a protection that ordinary Treasury bonds and CDs cannot: a guaranteed real return regardless of how high inflation runs. Sanjib Saha, writing for HumbleDollar, argues that anyone holding "safe" fixed-income money for more than three years is quietly exposed to the risk that a prolonged inflation surge could destroy purchasing power before their bond matures, as happened in the late 1960s through early 1980s. TIPS sidestep that risk because the principal rises with actual inflation, and the "real interest rate" — how much purchasing power the investment will gain — is locked in at purchase. There is one cost: if inflation stays below the "breakeven rate" (the yield gap between a nominal Treasury and an equivalent TIPS, roughly the market's inflation forecast), the nominal bond investor ends up with more purchasing power. But TIPS caps that downside — even in severe deflation, the principal returned at maturity cannot fall below the original face value, so the opportunity cost is limited while the inflation upside is not. For buyers shopping the secondary market, Saha recommends favoring newer TIPS issues with a low inflation-adjustment factor, because older issues with decades of accumulated inflation adjustments have more room to lose value during a deflationary period before hitting the $1,000 floor — adding a risk that newer issues largely avoid.
