Are Ben Carlson's Best Inflation Hedges Actually Inflation Hedges?
Ben Carlson says the best inflation hedges are a good job, a fixed-rate mortgage, and stocks. Two of the three aren't technically hedges. Here's what the research says.
Ben Carlson of A Wealth of Common Sense argues that the three best inflation hedges are a good job, a fixed-rate mortgage, and stocks for the long run. As household-planning advice, that list is hard to argue with. A strong career, a locked-in mortgage payment, and ownership of productive businesses all help when prices rise over time.
The trouble is the word hedge. Helping a household cope with inflation over a lifetime is a different property from hedging inflation when it shows up, and only one of Carlson’s three items clears the technical bar. Here is how each holds up.
| Carlson’s “inflation hedge” | Technical verdict | More precise label |
|---|---|---|
| A good job | Not usually a hedge | Human-capital resilience |
| A 30-year fixed mortgage | Yes, on the liability side | Fixed nominal debt hedge |
| Stocks for the long run | Not a reliable hedge | Long-run real-return asset |
What an Inflation Hedge Has to Do
A hedge preserves purchasing power when inflation rises, especially when it surprises to the upside. That is a higher bar than beating inflation eventually. Zvi Bodie set it in his 1976 paper Common Stocks as a Hedge Against Inflation, which measured hedging effectiveness by how much an asset reduces the risk in an investor’s real return. By that test, stocks were a perverse hedge over 1953 to 1972: Bodie concluded that to use them to reduce inflation risk, an investor would have had to sell them short.
Instruments with contractual CPI linkage clear the bar directly. The Summitward pillar post, The Best Inflation Hedges Are Boring, works through why outpacing inflation over decades is a separate property from hedging an inflation shock. This companion applies that distinction to Carlson’s three specifically.
A Good Job Is Human-Capital Resilience
For most working households, human capital is the largest asset on the balance sheet, so a good job may be the single most important inflation defense a person has. If wages rise faster than a household’s own cost of living, inflation does far less damage.
A paycheck is still not a technical inflation hedge, because it is not indexed to CPI. Raises depend on labor-market tightness, employer profitability, occupation, productivity, bargaining power, and job mobility. Fama and Schwert’s 1977 study Asset Returns and Inflation found that labor income had little short-term relationship with either expected or unexpected inflation. Recent wage data show the same ambiguity: the Bureau of Labor Statistics reported that real average hourly earnings rose just 0.3 percent from March 2025 to March 2026, as nominal earnings grew 3.5 percent against 3.3 percent CPI-U inflation. Some years wages win that race; other years they lose it.
The advice is excellent even so: build rare skills, keep career optionality, and avoid a stagnant income path. From a portfolio-construction view, though, a job is risky, personal, and exposed to recessions, which makes it human-capital resilience rather than a CPI-linked contract.
A 30-Year Fixed Mortgage Is a Liability-Side Hedge
This is Carlson’s strongest example, and it is a real hedge, just not an asset-side one. You borrow fixed nominal dollars and lock the monthly principal-and-interest payment. If inflation surprises higher, the real value of those fixed payments falls, and you repay the lender in cheaper dollars. The St. Louis Fed describes the mechanism in The Impact of Inflation’s Wealth Transfer Effect: unexpected inflation lowers the real value of nominal debt and transfers wealth from lenders to borrowers, with middle-income households often the big net borrowers through their mortgages.
The hedge comes with conditions. It only helps after the rate is locked, so a new buyer facing high prices and high rates gets no benefit. It protects against unexpected inflation, not the inflation already priced into the mortgage rate. It works best when income rises alongside prices, and it reverses under deflation, when fixed payments grow more burdensome in real terms. A mortgage is also borrowed money, so it can hedge inflation and still be a poor decision if the house is unaffordable. The full mechanics, with a calculator that quantifies the effect, are in Is a 30-Year Fixed Mortgage an Inflation Hedge?
Stocks Are a Long-Run Real-Return Asset
Stocks are ownership claims on real businesses that can raise prices, so the intuition is that equities should track inflation. Carlson notes that U.S. stocks have beaten inflation by nearly 7 percent per year over the past century, with dividends and earnings growing faster than inflation as well. That is a strong long-run wealth-building case, and it is about expected real return rather than hedging.
Over the horizons when investors most want protection, the evidence on stocks is unfriendly. Fama and Schwert found common stock returns negatively related to expected inflation and probably to unexpected inflation too. A 2023 Federal Reserve study, Inflation Surprises and Equity Returns, finds the U.S. stock response to inflation surprises is on average robustly negative, and largest when inflation expectations and the output gap are both running high. Andrew Ang, Marie Brière, and Ombretta Signori document the same pattern at the stock level in Inflation and Individual Equities: the aggregate market hedges inflation poorly, and individual stocks’ inflation sensitivities move around so much over time that a reliable inflation-hedge stock portfolio is hard to build out of sample.
The mechanism is straightforward. Higher inflation can raise nominal revenue, but it also lifts input costs, compresses margins, raises discount rates, pressures valuation multiples, and can trigger tighter monetary policy. Stock prices are discounted claims on uncertain future real cash flows, so they can fall in exactly the window a hedge is supposed to help. There is a horizon caveat worth crediting: Jacob Boudoukh and Matthew Richardson’s Stock Returns and Inflation: A Long-Horizon Perspective shows stocks look more inflation-sensitive at a five-year horizon than a one-year one. That supports Carlson’s long-run point; it does not make equities a dependable hedge against a near-term inflation shock.
History fits the theory. From 1966 to 1982, a brutal inflationary stretch, U.S. stocks delivered roughly zero real return while one-month Treasury bills narrowly beat inflation with far less volatility (see Damodaran’s historical return dataset for the underlying numbers; the episode is the subject of Rational Reminder’s Episode 150). Stocks remain the core long-run growth engine for most investors. That is a different job from preserving purchasing power during an inflation shock.
What Actually Hedges Inflation
If the goal is explicit inflation protection, the direct instruments win. TreasuryDirect states that TIPS principal rises with inflation and falls with deflation, with a floor at original principal at maturity, and that I Bond rates combine a fixed rate with an inflation component that resets every six months from CPI-U. Add fixed-rate debt on the liability side, where prudent, and you have the short list. The account-placement and after-tax details live in the pillar guide.
Where Carlson Is Right
The practical wisdom holds up. Inflation is personal: a household’s own rate depends on where it lives, whether it rents or owns, how much it drives, and what it spends on childcare and medical care, none of which matches headline CPI. Most people should not try to trade inflation tactically, since by the time it is obvious the market has usually moved. And raising income can matter more than any portfolio tweak.
The gap is in the label. A good job is an inflation defense, a fixed-rate mortgage is a liability-side inflation hedge, and stocks are a long-run real-return asset. Group all three under “inflation hedge” and the word starts to mean any asset with a positive long-run return, which drains it of the precision that makes it useful.
Frequently Asked Questions
Is a good job an inflation hedge?
Not in the technical sense. Wages are not indexed to CPI, and Fama and Schwert found labor income has little short-term relationship with inflation. A good job is the most important inflation defense most households have, but it is human-capital resilience rather than a hedge that adjusts contractually when inflation rises.
Is a fixed-rate mortgage really an inflation hedge?
Yes, on the liability side. Fixed nominal debt loses real value when inflation surprises higher, which benefits the borrower. The hedge only applies after the rate is locked, protects against unexpected rather than priced-in inflation, and reverses under deflation.
Are stocks an inflation hedge?
Not a reliable one over the short and intermediate horizons that matter for inflation protection. Stocks have historically beaten inflation over multi-decade windows, but their measured response to inflation surprises, in both Fama and Schwert and the 2023 Federal Reserve study, is on average negative. They are a long-run real-return asset, not a shock hedge.
What is the best inflation hedge?
For a U.S. household worried about CPI, the cleanest hedges are the CPI-linked instruments: I Bonds and TIPS, plus fixed-rate debt on the liability side. These match the specific risk rather than merely tending to outrun it.
Is Ben Carlson wrong about inflation hedges?
He is directionally right as household-planning advice and loose on the technical label. All three of his items help households handle inflation, but only the fixed-rate mortgage is a hedge in the asset-pricing sense.
