Skew as Market Signal

Skew

The term “skew,” within the context of cryptocurrency derivatives and options trading, refers to the shape of an implied volatility surface, specifically the asymmetry in volatility expectations across different strike prices for options expiring at the same date. It quantifies the difference between out-of-the-money (OTM) put options and OTM call options, revealing market sentiment regarding potential downside versus upside risk. A steeper skew, often observed in traditional markets and increasingly in crypto, suggests a greater demand for downside protection, reflecting a perceived higher probability of price declines.
