Is bitcoin a good hedge against inflation?

Bitcoin’s pitch as “digital gold” rests on a fixed supply of 21 million coins and a verifiable issuance schedule. In theory, scarcity should protect purchasing power as central banks print more currency. The reality is messier.

Short-run evidence is genuinely positive. Choi and Shin’s 2021 study in Pacific-Basin Finance Journal found that bitcoin does appreciate after positive inflation shocks — measured against breakeven-inflation surprises, not headline CPI. Smales (2024) reached a similar conclusion in the Australian Accounting Review: both gold and crypto returns rise when inflation expectations climb. Rodriguez (2025) confirmed the pattern in newer data. On a 3-to-12-month horizon, the inflation-hedge story holds up.

Long-run evidence is weaker. Bitcoin’s correlation with inflation expectations drifts. From 2014 to 2018, it tracked gold; from 2019 to 2021, it tracked tech stocks; in 2022 it crashed alongside risk assets when rates rose. The same asset cannot be a risk-off hedge and a high-beta tech proxy at the same time. Most academic literature now classifies bitcoin as a “risk-on” asset that occasionally behaves like an inflation hedge — not as a reliable store of value across cycles.

There’s also a definitional problem. “Hedge” in finance means a low or negative correlation with the thing you’re hedging. Gold’s 10-year correlation with realized US inflation sits around 0.2-0.3. Bitcoin’s sits closer to zero, and varies wildly by sample period. A hedge that works in some quarters and fails in others isn’t really a hedge — it’s a tactical bet that depends on the macro regime.

If you want inflation protection in a diversified portfolio, the practical answer is still boring: TIPS (Treasury Inflation-Protected Securities), short-duration Treasuries, and a small gold allocation. Bitcoin is fine as a speculative allocation if you have the risk tolerance, but treating it as the inflation wing of your portfolio is overstating what the data shows. Most of the inflation-hedge case for bitcoin lives in narrative, not in realized correlation.
