Crypto Selloff: Volatility, Skew, and Calendar Spread Positioning

Summary

This market review links a sharp crypto selloff to changes in realized volatility, implied volatility, options skew, and trading flow. It reports elevated realized volatility in BTC and ETH alongside a deeply negative volatility risk premium, meaning the underlying moves exceeded what options had implied. In that setting, the author warns that short gamma positions face greater risk and favors upside calendar spreads, which can earn theta while limiting some downside exposure. The article also notes heavier demand for short-dated puts, with near-term skew more bearish than longer-dated skew, and reports BTC flow skewed toward put buying and call selling.

The review adds that ETH’s realized volatility caught up with BTC’s, leaving the stated implied volatility spread between them elevated. Its evidence consists of contemporaneous market levels and options-flow observations, not a tested strategy or causal analysis. Calendar spreads still carry market and volatility risks, and the proposed positioning is a view for the described conditions rather than a general rule. The note also includes promotional material that does not add to the analysis.

Key ideas

• A volatility risk premium below zero indicates that realized movement exceeded implied movement over the described period.
• The author cautions that short gamma positions are hazardous when support breaks and realized volatility surges.
• Upside calendar spreads are proposed as a way to collect theta while limiting some downside exposure.
• Demand for short-dated puts steepened near-term skew, while longer-dated skew stayed less bearish.
• The reported market observations motivate a tactical view but do not establish a tested trading edge.
