Reading Bitcoin and Ether Option Flows During a Breakout and Volatility Reversal
Summary
This weekly commentary follows Bitcoin and Ether derivatives through a sharp upside move and the subsequent volatility selloff. Around the monthly expiry, the breakout lifted near-term implied volatility and strengthened call skew, while reported option activity included two-way trading in short-dated Bitcoin strikes. Ether’s realized volatility rose more sharply, helping explain its larger increase in short-dated implied volatility; the author attributes longer-dated changes mainly to realized volatility rather than fresh option demand.
The later discussion describes volatility sellers in puts, strangles, and straddles, followed by renewed buying of Bitcoin and Ether calls as prices rallied and sentiment improved. Examples include call spreads funded by selling higher-strike or later-dated calls, alongside short-dated call purchases. The commentary notes alternative interpretations for some complex trades, including rolling existing exposure or positioning for changes in skew or forward volatility. It is a qualitative reading of reported flows and market conditions, not a backtest; the causes and intent behind individual trades remain uncertain, and macroeconomic events could alter the outlook.
Key ideas
- A sharp spot move raised near-term implied volatility and firmed call skew, while medium-term measures changed less.
- Ether’s stronger realized volatility helped account for its larger short-dated volatility increase.
- Traders sold volatility after the move, then some bought calls as Bitcoin and Ether sentiment improved.
- Call spreads funded by selling higher-strike calls can express upside while limiting the cost of the purchased calls.
- Observed flow does not establish trader intent, and the commentary offers several possible readings of complex trades.
