Volatility Percentile
Rolling 30-day realised volatility expressed as a historical percentile rank. Low readings mark compression regimes, high readings mark panic peaks.
What is it?
Volatility Percentile expresses Bitcoin's 30-day realised volatility as a percentile rank against its full history. Realised volatility is calculated as the annualised standard deviation of daily returns over a 30-day rolling window. This raw figure is then ranked via an expanding percentile (full history, minimum 365 days) to produce a 0-100 value (0 = lowest volatility ever observed, 100 = highest).
How to read
The chart segments volatility into five structural regimes: very low (0-10th percentile), low (10-30th), neutral (30-70th), elevated (70-90th), extreme (90-100th). Extreme low percentiles (< 10th) mark volatility compression: the market is simply moving less than it usually does. Extreme high percentiles (> 90th) mark panic peaks. Volatility itself is strongly mean-reverting, which is why such readings rarely persist for long. The chart says nothing about direction, and nothing about what comes next.
Key zones
Compressions below the 5th percentile are the rarest conditions: 255 sessions out of 5,460 since 2011, roughly one in twenty-one. They arrive in clusters rather than isolated days, notably mid-2023 and late 2025. Conversely, percentiles above the 95th mark maximum volatility points, and have been followed by compression toward the 50th percentile within 30 to 60 days. Bitcoin's volatility spends approximately 70% of its time between the 20th and 80th percentile.
What to observe
Compression duration is what the chart makes visible. A prolonged compression (percentile below the 15th for more than three weeks) is itself an unusual state, and its length is readable directly off the curve. Rapid transitions from the 10th to the 90th percentile in under two weeks mark exogenous shocks rather than an internal market dynamic. The secular decline of median volatility across cycles reflects the maturation of the market and its liquidity.
Historical context
Compressions and panic peaks are both recurring features of Bitcoin's history. Notable peaks: March 2020 (99th percentile, COVID crash, around 180% annualised volatility), May 2021 (97th percentile, China mining ban), November 2022 (96th percentile, FTX). Readings below the 5th percentile have clustered in a handful of episodes, among them July 2020, July and August 2023, then August and September 2025. Bitcoin's median volatility has fallen from around 80% annualised over 2013-2017 to around 55% over 2020-2024, a maturation the chart makes visible over the long run.
Expert notes
The percentile is calculated via an expanding window over the full history since 2010 (>5,000 observations, minimum 365 days required). A maturation bias exists: early years (low liquidity, extreme volatility) inflate the upper tail of the distribution, mechanically making recent volatility 'low in percentile' even if still elevated in absolute terms against traditional assets. Volatility is calculated close-to-close (not high-low) for consistency with Rolling Sharpe and Risk-Adjusted Return.
Common mistakes to avoid
A low percentile does NOT mean 'buy' and a high percentile does NOT mean 'sell'. The percentile measures the volatility regime, not direction. Volatility compressions can resolve downward just as easily as upward. On top of that, comparing Bitcoin's percentile to traditional equities is misleading: Bitcoin's 50th percentile volatility (~55% annualised) exceeds the 99th percentile of most S&P 500 stocks.
