Cryptocurrency derivatives markets are facing a pivotal session on August 21, 2026, as $2.09 billion in Bitcoin and Ethereum options expire on Deribit while futures exchanges report $133 million in liquidations within one hour and roughly $940 million over 24 hours.
On Deribit, Bitcoin options with a notional value of $1.75 billion are set to expire at 8:00 a.m. UTC, alongside Ethereum options worth $340 million. Bitcoin’s put/call ratio stands at 0.81, signaling more call than put open interest, and its max pain price is $67,000. Ethereum’s put/call ratio is 0.82, with a max pain price of $2,000. Max pain theory suggests market makers may try to pull prices toward these levels to maximize losses for option buyers, potentially increasing volatility before settlement.
At the same time, leveraged futures positions have been unwinding rapidly across major exchanges including Binance, OKX, and Bybit. The $133 million one-hour liquidation spike and $940 million 24-hour total indicate that the market was over-leveraged and that both long and short positions were caught by sudden price swings. This cascade of forced closures can amplify short-term price moves and add to the uncertainty around the options expiry.
Despite the intense derivatives activity, analysts note that monthly expiries are routine and their broader market effect is typically short-lived. The put/call ratios below 1 reflect a generally bullish or neutral sentiment among options traders, while the liquidation event serves as a warning about high leverage. Traders should watch for volatility around the 8:00 a.m. UTC expiry, but long-term investors are unlikely to see a fundamental shift.
For market participants, the combination of a large options expiry and a leverage flush makes August 21 a critical session for short-term price discovery in Bitcoin and Ethereum.
