Deribit's $16B Options Expiry Set to Unleash Market Volatility
On September 25, the crypto derivatives market will undergo a significant stress test as $15.9 billion in Bitcoin options and $2.1 billion in Ethereum options expire on Deribit. This event represents one of the largest quarterly settlements of the year, with approximately 37% of Deribit's total Bitcoin open interest at stake.
The put/call open interest ratio on expiring contracts ranges from 0.69 to 0.76, indicating that traders have built up considerably more upside bets than downside protection. Of the $9.4 billion in call options scheduled to expire, roughly 55% are currently in the money, given Bitcoin's trading range between approximately $85,000 and $86,300.
Deribit CEO Luuk Strijers has flagged the likelihood of increased volatility and a potential reset in trading ranges after the settlement clears. The concentration of open interest at higher strike prices, particularly in the $85,000 to $100,000 band, adds texture to this concern.
