Pre-FOMC Bitcoin Call Spreads and Upside Positioning

Summary

This brief options flow note describes Bitcoin positioning before and after a Federal Reserve meeting. It reports early risk-off activity followed by purchases of call spreads and outright calls at higher strikes, alongside the sale of existing March calls. The author interprets the upward strike accumulation as a shift in attention toward higher price targets. The note also says traders used call spreads to limit vega exposure while implied volatility was elevated ahead of the event, and that near dated implied volatility fell after the expected rate decision arrived without a major surprise.

The evidence consists of reported trade sizes, expiries, strike ranges, and the timing of volatility changes. It provides a concise example of how traders may use defined call spreads to retain upside exposure while reducing sensitivity to implied volatility around a scheduled event. However, it is a single episode of flow commentary and does not include full trade records, a formal event study, or evidence that the reported positioning predicted subsequent prices. Trader motives and the interpretation of the flow remain the author’s judgments.

Key ideas

• The note reports a move from pre-meeting risk reduction toward Bitcoin call buying and call spreads.
• Call spreads were used to keep vega exposure lower while implied volatility was firm ahead of the event.
• Near dated implied volatility declined after the rate decision matched expectations.
• Reported upside positioning shifted toward higher strikes, though the note does not establish predictive value.
