Volatility Smile Skew

Definition

The volatility smile skew represents the observed empirical phenomenon in options markets where implied volatility varies across different strike prices for a fixed expiration date. In cryptocurrency derivatives, this curve typically displays a pronounced bias, reflecting market participant expectations regarding tail risk and sudden directional price movements. This non-linear relationship deviates from the Black-Scholes model assumption of constant volatility, serving as a critical indicator of market sentiment and the cost of hedging against asymmetric outcomes.
