No single asset class reliably hedges inflation in every cycle, and the most recent one proved it. Between 2021 and 2025, when U.S. CPI surged from 4.7% to a peak of 8.0% before settling back to 2.6%, gold, real estate, fine art, and Bitcoin all responded differently, and none of them followed the script their proponents had written. Gold delivered strong nominal gains late in the cycle but lost ground early. Real estate boomed and then stalled under rising rates. Art held value quietly while the broader market recalibrated. And Bitcoin, sold for years as "digital gold," crashed 64% in the worst inflation year before rebounding on entirely different catalysts. We spend a lot of time thinking about real assets and purchasing power, so this question is close to home. What follows is what each asset actually did during the recent inflation episode, what the correlation data says, and what we think it means when you are building a portfolio meant to preserve purchasing power.

A note worth getting out of the way up front. Common wisdom still treats the dollar as a good store of value. Google how much purchasing power the dollar has lost over the past century and the number is roughly 97%. On an annualized basis inflation barely registers. Compounded over decades, it gets concerning. That is the real reason any of these four assets matters.

What did inflation actually do between 2021 and 2025?

U.S. consumer prices rose 4.7% in 2021, then 8.0% in 2022 (the highest annual average since the early 1980s), before falling to 4.1% in 2023, 2.9% in 2024, and roughly 2.6% in 2025. Cumulative inflation over those five years topped 20%, meaning a dollar at the start of 2021 bought about 80 cents' worth of goods by the end of 2025.

That kind of sustained price increase is the exact environment where "inflation hedge" claims get tested, and the results were mixed across the board. A February 2025 study from the CFA Institute found that broad real-asset benchmarks did not move in the same direction as inflation from 2021 to 2023. Among the asset classes they examined, only commodities (mostly energy) managed to outpace CPI during that window. Gold, real estate, and infrastructure all fell short.

The takeaway from that study sets up everything that follows. Hedging inflation is harder than buying an asset with "real" in its name.

Is gold a good inflation hedge?

Gold works as a long-run hedge, but the timing rarely matches the inflation you are trying to hedge. It returned -3.6% in 2021, -0.4% in 2022, +13.2% in 2023, and +27.2% in 2024, according to World Gold Council data. For the first two years of the inflation spike, gold did almost nothing. It actually lost purchasing power in both 2021 and 2022 when measured against CPI.

The rally came later, driven less by inflation and more by central bank buying, geopolitical risk, and eventual rate-cut expectations. The World Gold Council reports that since 1971, only 16% of gold price variation can be explained by CPI changes. Over the 2021-2025 stretch specifically, the correlation between gold and inflation ran at about 0.76, but that number is inflated (no pun intended) by the lag. Gold rose after inflation peaked, not during the worst of it.

Academic research from a 2025 paper published in the International Review of Financial Analysis confirms the pattern. Gold functions as a long-term inflation hedge after adjusting for structural breaks, but at medium horizons of 32 to 128 months, the relationship is volatile and heavily shaped by real interest rates. When real rates are high, gold's holding cost rises, and the hedge breaks down.

For the 2021-2025 period, gold's cumulative nominal return was roughly 40%. Adjusted for cumulative inflation of about 20%, the real return was around 17%. That is a win, but only if you held through two flat years at the start.

Does real estate protect against inflation?

Real estate hedges inflation right up until rates rise to fight that inflation, and then the mechanism turns on itself. Residential property looked like the ideal hedge in 2021, with the S&P Case-Shiller National Home Price Index up 18.9% year-over-year. Then the Federal Reserve began raising rates in March 2022, and the picture changed fast.

Home prices peaked mid-2022 and then declined for about seven months. By 2023, annual gains had slowed to around 3.8%. In 2024, the national index posted a 3.9% annual increase, and 2025 saw the weakest gains since 2011, with prices rising just 1.3%, according to Housing Wire's analysis of Case-Shiller data.

The problem is straightforward. Real estate hedges inflation through two channels: rising replacement costs and the ability to raise rents. Both channels get choked when interest rates rise, because higher mortgage rates reduce buyer demand and compress prices. During the 2021-2023 inflation episode, the CFA Institute found that liquid real estate (REITs) showed only a 0.1 correlation with CPI inflation, and the broader real asset category posted a slightly negative correlation of -0.04 with headline CPI.

Commercial real estate fared worse. Office valuations dropped sharply through 2022 and 2023 as remote work reduced demand and higher cap rates repriced assets downward. The FTSE Nareit All Equity REITs Index fell roughly 25% in 2022 before recovering partially in 2023 and 2024.

In real terms, someone who bought a home at the start of 2021 would have seen significant nominal gains but, after accounting for higher mortgage costs and slowing appreciation, a shrinking real return by 2025. A 2025 paper in Real Estate Economics found that real estate hedges expected inflation over time but fails against unexpected inflation, which is precisely the kind that hurts most.

How does fine art perform as an inflation hedge?

Art's case rests on different logic than gold or real estate, and the logic is the same one that makes it a diversifier. Art prices are driven primarily by collector demand, scarcity, and cultural value, with limited ties to interest rates or consumer spending. That disconnect is the source of both its appeal and its limitations.

The global art market reached $65 billion in 2022, dropped to $57.5 billion in 2023, and then grew 4% to $59.6 billion in 2025, according to the Art Basel and UBS Global Art Market Report 2026. The decline in 2023 was driven more by a pullback in ultra-high-end consignments than by any response to inflation or rates. Auction sales rose 9% in 2025, with the U.S. market accounting for $26 billion of the total.

The Artprice100, an index tracking the 100 most liquid blue-chip artists at auction, posted a 3% gain in 2022 and a 1.55% gain in 2023. Neither year beat inflation. But the index has returned roughly 589% since 2000, compared to 224% for the S&P 500 over the same period. The long-run performance is strong. The year-to-year hedge is inconsistent. Both things are true at once.

A 2024 study published in Applied Economics examined art's inflation-hedging properties across the U.S., U.K., and France. The findings were geographic. In France, art acts as a reliable long-term inflation hedge, likely because of the depth and cultural entrenchment of the French art market. In the U.S. and U.K., the relationship was weaker and statistically insignificant.

Here is the part we think most investors get backwards. Since 1997, art's correlation with inflation has been measured at 0.26, slightly higher than gold's 0.24 over the same stretch. That is a mild positive. But the real value of art in a portfolio during inflationary periods is its low correlation with stocks and bonds, not any direct link to CPI. Art prices move on their own schedule, and that independence can reduce overall portfolio volatility when other assets are selling off together. We would frame art as a diversifier that happens to hold value through inflation, rather than a thermostat tracking it.

There is also a scarcity argument underneath all of this. Art offers something neither gold nor a printed currency can claim, which is supply that often shrinks over longer hold periods. No new Basquiats will ever be painted. With each passing decade the pool of available blue-chip works tends to get smaller as museums permanently acquire pieces and they leave the market for good. That is a slow tailwind, and it has nothing to do with what CPI prints in any given month.

Is Bitcoin an inflation hedge?

Bitcoin was marketed heavily as an inflation hedge starting in 2020, when institutional adoption accelerated and comparisons to "digital gold" became common. The 2021-2022 period tested that thesis and found it lacking.

Bitcoin rose roughly 59% in 2021, then fell approximately 64% in 2022, the year when inflation was highest. It recovered with a gain of about 155% in 2023 and roughly 120% in 2024, driven by the approval of spot Bitcoin ETFs and post-election enthusiasm rather than any connection to consumer prices.

A 2024 study published in Finance Research Letters found that Bitcoin's inflation-hedging property is sensitive to the price index used and the period analyzed. The hedge only holds for CPI shocks, not broader price measures, and the relationship weakens significantly when you exclude Bitcoin's early years (pre-2017). Another 2024 paper in Accounting & Finance concluded that cryptocurrencies do not offer investors a viable alternative to gold for hedging inflation, noting that crypto returns tend to fall on days when CPI data is released.

Bitcoin's R-squared with CPI changes sits at just 0.27 over the past five years, meaning only 27% of its price movement can be traced to inflation metrics. The other 73% is driven by liquidity conditions, risk appetite, regulatory news, and speculative flows.

During the 2022 inflation peak, Bitcoin behaved like a high-beta tech stock. It fell alongside the Nasdaq while gold held flat. The structural break, identified by multiple academic papers, occurred around March 2020. After that point, Bitcoin's returns became more closely tied to equity markets and less to inflation expectations. One note on scarcity, since the "digital gold" pitch leans on it. Bitcoin's supply is capped, which is real. Art's supply does something stronger over long horizons, which is decrease. We make the comparison because the marketing invites it, and the data does not flatter the comparison.

How did the four assets score against inflation?

Putting all four assets side by side for the 2021-2025 period:

  • Gold cumulative nominal return: roughly +40%. Real return after inflation: roughly +17%. Correlation with CPI: 0.76 (lagged), but only 0.16 of price variation explained by CPI historically.
  • Residential real estate (Case-Shiller) cumulative nominal gain: roughly +30%. Real return after inflation: roughly +8%. REIT correlation with CPI: 0.1.
  • Fine art (Artprice100) cumulative nominal gain: roughly +5-7% (2022-2023 only; full five-year data incomplete). Correlation with inflation: 0.26 since 1997. Global market recovered to $59.6 billion in 2025.
  • Bitcoin cumulative nominal return: roughly +300% (extremely volatile path). R-squared with CPI: 0.27. Correlation driven mostly by non-inflation factors.

The numbers tell a fairly clear story. Gold was the strongest inflation hedge over the full five-year period, but only because of a late surge. Real estate hedged partially and was compromised by the same rate hikes meant to fight inflation. Art held value with low volatility, offering diversification more than direct inflation protection. Bitcoin generated the highest raw returns, but its path, a 64% crash followed by a 155% recovery, bears no resemblance to inflation hedging. It is a high-beta growth asset that occasionally shares a sentence with gold.

What does the data say about building an inflation-aware portfolio?

The honest conclusion from 2021-2025 is that no single asset cleanly hedged inflation when it mattered most. The CFA Institute's research found that among all the real asset categories examined, only energy commodities consistently outpaced CPI during the inflation surge.

That does not mean these assets are useless in an inflation-aware portfolio. It means the framing is off. The better question is which combination of assets preserves purchasing power across different environments. We would answer it by what each piece contributes.

Art contributes low correlation. Its 0.26 correlation with CPI is modest, but its near-zero correlation with equities and bonds is the part that earns its place. When stocks and bonds fell together in 2022 (one of the worst years for 60/40 portfolios in decades), art prices barely moved. We tend to think of a small art allocation as something largely indifferent to the forces driving everything else, which is what diversification is actually supposed to buy you.

Gold contributes crisis optionality. It may not respond to inflation in real time, but it tends to reprice sharply when monetary policy shifts or geopolitical risk spikes.

Real estate contributes income. Rental cash flows can rise with inflation over time, even if property values are sensitive to rate cycles in the short term.

Bitcoin contributes something else entirely. It is a bet on adoption, regulation, and liquidity, and on price stability least of all. Including it in a portfolio for inflation protection misreads what the asset does. We would rather be honest about that than dress it up.

None of this is investment advice, and none of it is a forecast. There is never a crystal ball. It is one cycle of evidence, read as carefully as we can read it.

The Bottom Line

  • Gold was the best-performing inflation hedge over the full 2021-2025 cycle, with a real return of roughly 17%, but it lost ground in the two worst inflation years and only rallied after CPI had already peaked.
  • Real estate hedged inflation well in 2021, then stumbled badly as rising interest rates undermined the very mechanism (price appreciation) that was supposed to provide protection.
  • Fine art offered low volatility and genuine diversification during the inflation episode, though its direct correlation with CPI is mild. Its value in a portfolio is more about what it does not correlate with than what it does.
  • Bitcoin generated massive nominal returns over five years but crashed 64% during peak inflation, making it a poor inflation hedge and a strong speculative asset.
  • No single asset reliably hedged inflation in real time during the 2021-2023 surge. The CFA Institute's research confirms that only energy commodities consistently beat CPI during that window.
  • The most effective inflation strategy is diversification across uncorrelated assets, including art, rather than concentration in any one "hedge."
