Volatility Smirk

Definition

A volatility smirk denotes the empirical observation in options markets where implied volatility varies across different strike prices for a singular expiration date. In cryptocurrency derivatives, this phenomenon manifests as a pronounced elevation in implied volatility for out-of-the-money put options compared to at-the-money or call options. Such a pattern suggests that market participants assign a higher probability to significant downward price movements, reflecting a collective hedge against localized market crashes.
