Volatility Stationarity

Analysis

Volatility stationarity, within cryptocurrency and derivatives markets, describes a statistical property where the statistical characteristics of volatility—specifically its mean and variance—remain constant over time. This differs from volatility clustering, common in financial time series, where periods of high volatility tend to be followed by more high volatility, and vice versa. Establishing stationarity is crucial for accurate option pricing models, as many rely on the assumption of constant volatility inputs, and its absence necessitates more complex stochastic volatility models. Accurate assessment of this property informs risk management strategies and the calibration of trading algorithms.
