Bitcoin Year-End Options Rolls and January Upside Positioning

Summary

This weekly options-flow commentary describes positioning as Bitcoin’s late-year rally faded in 2021. It reports purchases of December 31 puts, alongside January call spreads and calls, including positions expiring in early and late January. The author interprets the contrast as waning interest in the expiring December calls and stronger demand for January upside exposure.

The note says January implied volatility was above realized volatility and expects substantial December 31 open interest to roll into January, reinforcing a January term-structure bump. It also mentions possible year-end balance-sheet constraints and window dressing as contextual factors, while anticipating that the market may be pricing an early-January move. These are contemporaneous interpretations of reported trades and volatility levels, not a systematic study. The document does not provide a full transaction record or establish whether the expected roll or early-year move occurred.
