Bitcoin Rally Faces Triple Threat: Options Expiry, US Economic Data, and CME Futures Settlement

The Bitcoin market faces three tests in one day on Friday, September 25. The most immediate challenge is the expiration of $16 billion worth of options contracts on Deribit at 08:00 UTC, which could have a significant impact on liquidity and hedging conditions. About 60% of this open interest consists of calls, while puts account for around 40%. Mauricio Di Bartolomeo, co-founder of Ledn, notes that quarterly expirations like September's are often a two-act event, with the first part occurring when options on BlackRock's iShares Bitcoin Trust expired last week. He expects the same setup to unfold on Deribit.

According to ByKaranteli's open-source gamma model, the largest call wall is at $95,000 and the largest put wall is at $60,000. The zero-gamma level sits near $71,000, where dealer hedging flips character. If Bitcoin trades above this point, dealers who are net long gamma will sell into rallies and buy dips, while below it they will buy as price climbs and sell as it falls, amplifying the move.

With the market trading near $86,300, ByKaranteli's model places it comfortably inside a stabilizing zone. However, Deribit's DVOL index stands at 38.1, which is low by five-year history, indicating that options markets are pricing a moderate move. A one-standard-deviation move through Friday works out to about $2,720, or 3.15%, placing a rough band between $83,600 and $89,100.

The afternoon will bring two more tests for the Bitcoin market: US durable goods orders at 12:30 UTC and the University of Michigan's final September consumer sentiment reading, which includes inflation expectations, at 14:00 UTC. CME's September Bitcoin futures will settle against the CME CF Bitcoin Reference Rate at 15:00 UTC.
