Black-Scholes-Merton Limitations

Assumption

The Black-Scholes-Merton framework fundamentally relies on assumptions such as constant volatility and log-normal asset price distribution, which are demonstrably violated by the empirical characteristics of cryptocurrency markets. This model fails to account for the fat tails and extreme skewness inherent in digital asset returns, leading to systematic underestimation of potential drawdowns. Consequently, relying solely on this derivation for premium calculation introduces significant model risk into any trading operation.
