  • • Grayscale attributes the decline to market maturation, citing deeper liquidity, institutional participation, and regulated access through spot ETFs.

Summary
Bitcoin's one-year realized volatility has fallen to 43%, according to a new Grayscale report, placing the asset within the range of S&P 500 stocks. The figure is down from 81% five years ago and below the 64% ten-year average for the asset. Realized volatility, the measure Grayscale uses, tracks actual price swings over the past year.

The report places Bitcoin's volatility alongside equities directly. Over the past year, Bitcoin's volatility fell within the range of S&P 500 components and was lower than the volatility of 19% of the index's stocks. It remains above most individual names, but Grayscale says it no longer sits in a separate risk category. The firm links the decline to market maturation, including deeper liquidity, institutional participation, and regulated access through spot ETFs, which have smoothed out extreme swings. Grayscale's central message is that Bitcoin's reputation for high volatility may deter traditional investors, and that equity-style tools such as position sizing can apply to the asset.

The comparison arrives as inflation data keeps markets on edge. Bitcoin briefly fell near $80,000 after September CPI came in at 3.7% year over year, above the 3.6% expected. Traders feared the Federal Reserve could keep rates high or raise them further. BeInCrypto data shows Bitcoin recovering to about $82,285, up 0.81% over 24 hours and 1% over the week.

Grayscale also adds a caveat: one year of data cannot reveal how Bitcoin behaves across full market cycles, so the report invites a measured view rather than a definitive reclassification of the asset's risk profile.
