$18.1B Bitcoin and Ethereum Options Expiry Set to Trigger Volatility

Key Facts

Digital asset markets are bracing for potential volatility as a massive expiry of Bitcoin and Ethereum options approaches. According to reports, Bitcoin options with a notional value of approximately $16 billion are set to expire on the Deribit exchange this Friday, Sept. 25. The total value of expiring contracts, including Ethereum, exceeds $18 billion, placing traders on high alert for price fluctuations as the settlement deadline nears.

Open interest data reveals a significant distribution in market positioning, with call options accounting for about $9.6 billion and put options representing approximately $6.4 billion. This concentration of liquidity often leads to price pinning or hedging-related volatility as market makers adjust their portfolios. Such dynamics are characteristic of quarterly derivative expiries, which can trigger rapid shifts in market sentiment based on hedging flows.

In the absence of real-time price data, market participants are focusing on liquidity flows ahead of the 08:00 UTC settlement deadline. Following recent major economic catalysts, including the Fed interest rate decision on September 16, the focus shifts to how the crypto market will absorb these technical pressures. Investors should watch for sharp short-term swings as traders rebalance positions during this high-stakes quarterly event.
