Asset comparison: how each one actually responds to inflation

TIPS and I Bond figures reflect published rates as of mid-2026 (see Sources). 1970s-era real return figures for gold and stocks are drawn from long-run historical return datasets; real estate figures reflect commonly cited comparative studies of that period and vary by property type and market.

TIPS: the closest thing to a formal inflation guarantee

A Treasury Inflation-Protected Security’s principal is adjusted every six months based on the CPI-U, and interest is paid on that adjusted, growing principal – so both the underlying value and the interest payment rise with measured inflation. As of mid-2026, the 10-year TIPS real yield sat around 2.1-2.3%, meaning a buyer holding to maturity is contractually positioned to earn about that much above inflation, before tax. The catch: the IRS taxes the annual inflation adjustment to principal as income in the year it accrues, even though you don’t receive that cash until the bond matures or is sold – a real cash-flow quirk worth knowing before buying TIPS in a taxable account.

I Bonds: capped, but currently attractive

Series I savings bonds combine a fixed rate (locked in for the bond’s life) with an inflation-adjustment rate that resets every six months. For I Bonds issued May through October 2026, the composite rate is 4.26% – a 0.90% fixed rate plus a 1.67% semiannual inflation component. The practical limit is the purchase cap: $10,000 per person per year through TreasuryDirect, which makes I Bonds a meaningful but not portfolio-scale inflation hedge for most households.

Gold: strongest during the 1970s, more mixed since

Gold’s best-documented inflation-hedge period is 1973-1982, when it delivered an estimated real return of roughly 9% a year as its price rose from about $35 an ounce (the fixed official rate before the U.S. left the gold standard in 1971) to around $850 an ounce by 1980. That’s the case most commonly cited for gold as an inflation hedge – but it followed an unusual regime change (gold being freed from a fixed exchange rate), and gold has underperformed U.S. equities over most other multi-decade stretches, including much of the past 40 years.

Stocks: the 1970s counterexample

Long-run U.S. equity data generally shows stocks outpacing inflation over multi-decade horizons – but the 1973-1982 stagflation decade is the specific counterexample: the S&P 500’s total return was close to flat in real terms across the decade (some measures put it at roughly -2% a year after inflation), meaning an equity-only investor lost purchasing power for an extended stretch despite a positive-looking nominal return. That’s the historical basis for treating stocks as a long-run inflation hedge, not necessarily a short-term one.

Real estate: results depend heavily on the specifics

1970s data on real estate is more mixed than the gold-vs-stocks comparison. Commercial real estate returns in that period outperformed both stocks and bonds by some measures. Residential real estate showed the median home price rising roughly in line with cumulative CPI over 1970-1982 – a real return near zero on the home price alone, though homeowners using a fixed-rate mortgage benefited from paying back that debt in progressively cheaper dollars, which isn’t captured in the price-appreciation figure alone.

Frequently Asked Questions

What are TIPS and how do they protect against inflation?

TIPS are U.S. government bonds whose principal adjusts with CPI-U every six months, with interest paid on the growing principal. The 10-year TIPS real yield was around 2.1-2.3% as of mid-2026.

What is an I Bond and how is its rate set?

A Series I savings bond combines a fixed rate with a CPI-based inflation adjustment reset every six months. The composite rate for bonds issued May-October 2026 is 4.26%, capped at $10,000 per person per year.

How did gold perform during the 1970s stagflation period?

Gold delivered an estimated real return of roughly 9% a year from 1973-1982, rising from about $35 to roughly $850 an ounce – the strongest documented period for gold as an inflation hedge.

How did stocks and bonds perform during the same stagflation period?

Both underperformed after inflation. The S&P 500’s real return was close to flat to slightly negative across the decade, and bonds lost an estimated 3% a year after inflation as rates rose.

Is any single asset guaranteed to beat inflation?

No. TIPS and I Bonds have the only formal, government-backed CPI link, and both have real limits. Gold, stocks, and real estate have each beaten inflation in some periods and lagged it in others – diversifying, not picking one asset, is the more defensible approach.
