Crypto Derivatives Repricing After Bitcoin ETF Announcement Risk

Summary

This weekly report summarizes Bitcoin and Ether derivatives after the ETF announcement event. It describes front-end implied volatility falling as event risk passed, while both term structures remained moderately inverted. Demand for short-dated out-of-the-money puts and negative short-dated skew eased, and futures and perpetual markets continued to show interest in leveraged long exposure, though less than earlier in the month.

The report compares annualized futures yields, perpetual funding, at-the-money implied volatility, risk reversals, and volatility surfaces. Bitcoin volatility had fallen from its pre-announcement peak, while Ether’s surface remained elevated relative to its recent historical distribution. Surface changes also differed by tenor and option delta. These observations provide a cross-market snapshot, with stated data timestamps and a 30-day hourly reference distribution for surface z-scores. The report does not include the underlying tables in the supplied text or test whether these post-event patterns predict future returns.

Key ideas

• Front-end implied volatility declined after ETF announcement uncertainty passed.
• Demand for short-dated downside puts and negative skew eased after the event.
• Bitcoin and Ether futures and perpetual markets still showed demand for leveraged long exposure.
• Bitcoin and Ether differed in implied volatility levels and surface behavior after the announcement.
• The report is a time-stamped market snapshot rather than a test of predictive strategies.
