Bitcoin ETF Launch: Option Flows, Skew, and Volatility After the News
Summary
This market commentary tracks Bitcoin options activity after the spot ETF approval and launch. Initial buying targeted January calls and February–March call spreads, but flows later shifted toward January puts and call unwinds across several expiries. The author connects that change in positioning with firmer puts and a short-term skew that turned negative from the call side.
The note also contrasts a sharp increase in realized volatility with a muted implied volatility response, describing the resulting volatility risk premium as unusually negative. It reports Deribit volatility readings for BTC and ETH and mentions choppy two-way ETH spot flows amid discussion of a possible spot ETF. These are observations from a specific event window, not a tested trading strategy. The article offers no systematic performance evidence, and its brief flow summary cannot establish whether the positioning changes caused subsequent price moves.
Key ideas
- Initial call buying gave way to put buying and call unwinds after the ETF launch.
- The shift in option flows coincided with short-term skew turning negative from the call side.
- Realized volatility rose sharply while implied volatility reacted less, producing a reported negative volatility risk premium.
- The commentary describes event-specific flows and does not test a repeatable trading rule.
