Ethereum Options Volatility, Skew, Flows, and Dealer Gamma Positioning

Summary

This market recap compares Bitcoin and Ethereum options through realized and implied volatility, term structure, skew, trading flows, and dealer gamma. It describes falling Bitcoin realized volatility alongside firmer implied volatility, while Ethereum’s implied volatility and call skew rose as traders sought upside exposure. The account links these moves to changing demand for calls, the reduction of call overwriting, and dealer positioning; it also notes that Bitcoin’s curve and flows centered on different maturities than Ethereum’s.

The evidence consists of a qualitative snapshot of market prices and reported options activity for the week covered, including examples of call, put, straddle, and spread trading. The author interprets Ethereum’s flow and negative dealer gamma as factors that could support further volatility, while longer Bitcoin gamma exposure may help explain smaller moves. These are contemporaneous observations and interpretations, not a tested forecast or a general trading strategy. The recap provides no systematic methodology for validating its claims.

Key ideas

• The recap compares Bitcoin and Ethereum options across volatility, term structure, skew, flows, and dealer gamma.
• Ethereum call demand and call skew strengthened during the period described.
• The author connects reduced call overwriting and negative dealer gamma with higher implied volatility in Ethereum.
• Bitcoin’s reported dealer gamma became longer, which the author associates with smaller price moves.
• The observations describe one market period and do not establish a repeatable trading strategy.
