Short-Dated Volatility Skew

Definition

The short-dated volatility skew, particularly relevant within cryptocurrency options markets, represents the difference in implied volatility across strike prices for options expiring within a brief timeframe, typically one to four weeks. This phenomenon reflects heightened sensitivity to near-term events and anticipations of rapid price movements, often observed during periods of elevated market uncertainty or specific catalytic announcements. Unlike longer-dated skews which can incorporate broader macroeconomic expectations, the short-dated skew is primarily driven by immediate liquidity dynamics and sentiment surrounding imminent events, such as protocol upgrades or regulatory decisions. Consequently, it serves as a valuable, albeit fleeting, indicator of immediate market stress and directional bias, demanding careful interpretation alongside broader market context.
