Bitcoin Options Expiry Looms Large on Deribit

Bitcoin is trading around $86,000 ahead of one of the biggest events on this quarter's crypto derivatives calendar. On September 25, nearly $16 billion worth of Bitcoin options are set to expire on Deribit.

The size of the expiry matters because options do not simply represent bets on where Bitcoin will trade. They also influence how market makers hedge their exposure, and those hedging flows can affect short-term price behavior.

Ahead of a large expiry, market makers continuously buy and sell Bitcoin or related instruments to remain hedged as prices move. Depending on their positioning, this activity can absorb some market movements and contribute to lower realised volatility.

The $16 billion options setup heading into September 25 is particularly interesting. Of the roughly $16 billion in Bitcoin options open interest expiring Friday, calls account for about $9.6 billion, compared with around $6.4 billion in puts.
