ChainThink reports that on Friday at 16:00 Beijing time, approximately 81,700 Bitcoin options will expire on Deribit, with a notional value of about $6.44 billion.
Approximately 44,600 call options and 37,100 put options were traded, resulting in a put/call ratio of 0.83, indicating an overall bullish sentiment.
The most concentrated call option strike prices are $75,000 and $80,000, with open interest notional values of approximately $2.36 billion and $1.57 billion, respectively.
Deribit’s Chief Risk Officer stated that over the past week, Bitcoin rapidly rose from around $62,000 to $80,000, causing a large number of call options to move in-the-money and placing increased gamma hedging pressure on market makers.
The notional value of options within a 5% range of the current price exceeds $500 million, and as expiration approaches, increased gamma hedging may cause price "pinning" near key strike prices or accelerated volatility following a breakout.
