Bitcoin and Ether Options Volatility Around ETF Approval Events

Summary

This derivatives newsletter reviews Bitcoin and Ether price and options behavior around a sequence of SEC-related events, ETF approval, and the start of ETF trading in January 2024. It describes a muted immediate spot response to a false approval report, a delay before short-dated at-the-money implied volatility fell after the actual approval, and a brief rise in implied volatility before trading began. The report also notes that falling Bitcoin spot coincided with term structure backwardation and low put risk-reversal skew, while Ether implied volatility exceeded Bitcoin's across maturities.

The commentary discusses possible explanations for spot weakness, including sell-the-news activity or flows linked to GBTC conversion, while acknowledging that Bitcoin could simply be testing its range. It suggests volatility positioning around front-end maturities and skew, and discusses covered calls and market-maker capacity as possible structural themes. These are interpretations and trade ideas, not a documented test: the newsletter provides no strategy returns, causal evidence, or risk-adjusted results, and the event context limits how broadly the observations can be generalized.

Key ideas

• The newsletter observes that implied volatility responses to ETF news were delayed or short-lived.
• Bitcoin's spot decline coincided with term structure backwardation and low put risk-reversal skew.
• Ether implied volatility was reported above Bitcoin's across the term structure.
• The suggested volatility trades are interpretations without reported strategy performance evidence.
• The report discusses covered calls and market-maker capacity as possible developments in crypto options markets.
