Is Cash a Bad Investment During High Inflation?
In real terms, yes — cash loses purchasing power when inflation exceeds deposit rates. During the 2021–2023 surge, U.S. savers lost over 8% in real terms. But cash provides irreplaceable optionality during liquidity crises. Whether cash is an asset or a liability depends on the type of crisis you’re facing.

The short answer
“Cash is trash” became a popular refrain during the inflation surge of 2021–2022. And mathematically, it’s correct: if your savings account pays 0.5% and inflation is running at 9%, you’re losing purchasing power at a rate of 8.5% per year. That’s a real, measurable loss — even though your bank balance hasn’t changed.
But the full picture is more nuanced. Cash has a property that no other asset possesses: it’s always accepted, always liquid, and never falls in nominal terms. During a liquidity crisis — when stocks are crashing, bonds are being sold indiscriminately, and credit markets freeze — cash is the only asset that holds its value when everything else is being repriced downward.
The question isn’t whether cash is “good” or “bad.” It’s what type of crisis you’re preparing for.

What the data shows
Using FRED data (savings account rates, FEDFUNDS, CPIAUCSL, 1990–2024), the real return on cash has been negative for the majority of the past 15 years.
From 2010 to 2021, U.S. savings accounts averaged approximately 0.1–0.5% nominal while CPI inflation ran at 1.5–2%. The real loss was modest but persistent — roughly 1.5% per year, compounding to approximately 15% over the decade.
The 2021–2023 period was far more destructive. Inflation surged to 9.1% while savings rates remained near zero initially. Even after the Fed raised rates and savings yields reached 4–5%, the real return was only marginally positive (nominal yield minus ~3.5% inflation ≈ 1% real). The cumulative real loss over the 2021–2023 window was approximately 12–15% for cash holders.
Conversely, during the March 2020 crash, cash holders were able to buy the S&P 500 at a 34% discount — an opportunity that fully invested portfolios could not exploit. The investor who held 20% cash in February 2020 and deployed it in March significantly outperformed through year-end.

Why it happens — the macro mechanism
Cash operates differently in two fundamentally distinct crisis types.
During inflationary crises (1970s, 2021–2022), cash is the worst-performing asset. Inflation erodes purchasing power, and since cash yields are typically below inflation (central banks keep rates low initially to support the economy), the real loss is guaranteed. Every other asset class — equities, commodities, real estate, TIPS — provides at least partial inflation protection. Cash provides none.
During liquidity crises (2008, March 2020), cash is the best-performing asset on a relative basis. Everything else falls in nominal terms — stocks, bonds, credit, real estate. Cash doesn’t fall. It provides the ability to meet margin calls, cover expenses, and buy assets at distressed prices. In 2008, investors with cash reserves after the Lehman bankruptcy had access to once-in-a-generation buying opportunities.
The challenge is that you rarely know in advance which type of crisis will occur. Holding too much cash exposes you to inflation erosion. Holding too little leaves you unable to act during dislocations. The optimal cash allocation depends on your read of the macro regime — and the humility to acknowledge that crises rarely announce themselves in advance.
The negative real rate environment of 2009–2021 systematically penalized cash holders and rewarded risk-takers. This dynamic trained a generation of investors to view cash as permanently wasteful — a bias that may prove costly if the next crisis is inflationary rather than deflationary.
Cash is not an investment. It’s an option — and options are most valuable when uncertainty is highest.

What it means for different economic actors
Retirees face the sharpest tradeoff. Cash provides stability and liquidity for living expenses — essential qualities. But holding too much cash during inflation erodes the real value of their financial reserves. A common guideline: maintain 12–24 months of expenses in cash/short-term instruments, invest the remainder in a diversified portfolio that includes inflation-sensitive assets.
Active investors should think of cash as a strategic allocation, not a residual. Holding 10–20% cash during periods of elevated valuations (high CAPE, tight credit spreads) provides ammunition to deploy during corrections. The optionality value of cash increases when asset prices are expensive and the probability of dislocation is above average.
Young investors with long time horizons and stable income have the least need for large cash reserves. Their human capital (future earnings) functions as a bond-like asset, and time horizon allows them to ride through volatility. For this group, excess cash is typically a drag on long-term returns rather than a prudent hedge.
The most damaging error is selling risk assets during a crash to raise cash. This crystallizes losses and is the behavioral opposite of the optimal strategy. Cash for crisis deployment must be accumulated before the crisis, not during it.

Frequently asked questions
Are money market funds better than savings accounts during inflation?
Generally yes — money market funds adjust their yields faster than bank savings accounts as the Fed raises rates. During the 2022–2023 tightening cycle, money market yields reached 5%+ while many savings accounts still paid under 1%. The gap represents free money that many savers leave on the table. The tradeoff is slightly less FDIC protection (money market funds are not insured in the same way) and marginally less instant liquidity.
What about I Bonds as a cash alternative?
U.S. Series I Savings Bonds adjust their rate semiannually based on CPI inflation, providing direct inflation protection. During the 2022 inflation surge, I Bond rates reached 9.62% — vastly outperforming any cash instrument. The limitations are purchase caps ($10,000/year per person), a 1-year lockup period, and a 3-month interest penalty for redemption within 5 years. For the amount eligible, I Bonds are among the best inflation-protected cash alternatives available.
Does the “cash is trash” view still hold in 2026?
Less so than in 2021. With the Fed Funds rate elevated and inflation moderating, real returns on cash have turned slightly positive for the first time in over a decade. Cash is no longer being actively penalized by policy. However, if inflation re-accelerates or the Fed cuts rates faster than inflation falls, the negative real rate dynamic could return.
