BTC ETF Inflows and Call-Spread Positioning in Options Markets
Summary
The note links strong spot Bitcoin ETF inflows with bullish options positioning. It describes funds paying premium for call spreads across June and July expiries, while a market maker buys June calls to cover short gamma supplied by repeated call selling. The author also reports that Bitcoin implied volatility looked relatively cheap compared with Ethereum’s, whose volatility premium to realized volatility was elevated amid anticipation of an ETF decision.
The analysis observes positive correlation between spot and implied volatility, but says implied volatility rose less on this rally above $70,000 than in prior rallies, possibly reflecting an expected summer slowdown in ETF flows. It also notes that outright call buying by fast-money traders appeared to be tiring, while funds retained longer-dated call spreads. These are contemporaneous market observations and interpretations, not a tested trading strategy; the note provides no performance analysis and its explanation of positioning and future flows may not predict subsequent prices or volatility.
