Bitcoin's annualized volatility drops to 46%, but extreme daily moves exceed those of the 2018 bear market.

ChainCatcher report: Bitcoin has recorded 10 "3-standard-deviation" trading days so far in 2026, surpassing the 8 such days observed throughout the entire 2018 bear market. Although Bitcoin’s annualized volatility has declined from 84% in 2018 to approximately 46%, extreme price movements remain frequent relative to recent volatility levels. A "3-standard-deviation" event measures the degree to which price deviates from its recent normal range. Data shows that the average magnitude of such extreme moves in 2026 is around 7%, lower than the approximately 10% seen in 2018. Since 2024, Bitcoin’s volatility has averaged about 47%, comparable to NVIDIA’s, yet Bitcoin has experienced 26 "3-standard-deviation" trading days—far exceeding NVIDIA’s 8, the S&P 500’s 16, and gold’s 12. Market participants point to macroeconomic shocks and leveraged positions concentrated in derivatives markets as key factors driving persistent extreme volatility. When investors heavily sell options betting on market calmness, unexpected news can trigger forced liquidations of these concentrated positions, amplifying price swings. Deribit CEO Luuk Strijers notes that traditional Value-at-Risk (VaR) models fail to adequately capture tail risk during extreme events; investors should place greater emphasis on risk metrics such as Expected Shortfall. Meanwhile, increased institutional participation, deeper liquidity, and improved risk management are enhancing the market’s resilience to shocks—but do not imply that extreme volatility will disappear.
