Volatility Model Assumptions

Assumption

Volatility models in cryptocurrency derivatives rely on assumptions regarding distributional characteristics of asset returns, frequently employing the log-normal distribution despite evidence of skewness and kurtosis common in crypto markets. These models often assume constant volatility, a simplification that disregards the observed volatility clustering present in both traditional finance and digital asset spaces. Accurate parameterization of these assumptions, particularly regarding the shape and scale of the distribution, is critical for pricing and risk management, yet subject to model risk and estimation error.
