Bitcoin wobbles below $90K as $28B Boxing Day options expiry takes center stage

Bitcoin’s latest downtick under $90,000 is less about macro headlines and more about positioning. A record $28 billion notional options expiry on Boxing Day has moved to the front of the volatility queue, while gold’s strength underscores a bid for perceived safety as crypto traders manage year-end risk.

The single variable that matters this week is how dealers are hedging into that expiry. When open interest clusters around nearby strikes, hedgers often end up chasing spot moves to stay delta neutral. That feedback loop can amplify intraday swings into and out of the cut. With $28 billion rolling off, the market’s sensitivity to gamma flows likely outpaces typical holiday liquidity, which tends to be patchy and unforgiving of large orders.

What I’m watching most closely is whether the tape is pinned toward high open-interest strikes into the event, then releases once those contracts vanish. That “post-expiry air pocket” can go either way: if dealer hedges unwind in the same direction, the move can extend; if positioning flips, a snapback is common. Implied volatility tends to overprice these windows, but when the notional is this large, realized vol can catch up quickly.

Gold’s bid matters for psychology as much as allocation. When precious metals firm while BTC softens, it often signals defensiveness rather than a regime shift. In practice, some multi-asset funds trim crypto beta into optionality-heavy dates and rotate to cleaner havens where there’s less path dependency. That doesn’t speak to a structural view on Bitcoin as much as it reflects near-term risk budgeting around the expiry.

From a business standpoint, market makers and structured-product desks are managing two frictions: thin holiday books and unusually large end-of-year optionality. Spreads can widen and depth can evaporate precisely when hedging needs are highest. That’s how benign drift turns into jagged price action. For venues and brokers, the ethical tension is price transparency—retail participants can be whipsawed by flows they can’t see. Clearer education around expiries, dealer hedging, and basis dynamics would help close that gap without dumbing down the market.

For traders, a simple framework helps: - Map the major strikes near spot and note where a gamma flip is plausible. - Track 1-week/2-week implied vol and put-call skew for stress signals. - Watch funding and basis; sharp swings often confirm hedging pressure. - Prepare for a different market after expiry—flows and correlations can reset quickly.

None of this changes the longer-term Bitcoin narrative. It does suggest near-term price is being steered by mechanics rather than new information. With a record Boxing Day expiry, the path of least resistance will be set by how hedging supply meets thin holiday demand. Once that $28 billion rolls off, the market will tell us whether this dip was just positioning or something stickier.
