GreeksLive: Today, 21,000 BTC options and 129,000 ETH options expire.

According to GreeksLive, today 21,000 BTC options expire, with a Put/Call Ratio of 0.66, maximum pain at $78,500, and notional value of $1.6 billion; 129,000 ETH options expire, with a Put/Call Ratio of 0.92, maximum pain at $2,200, and notional value of $280 million. This week, BTC concluded a one-and-a-half-month rally amid muted market conditions; expiring BTC and ETH options each account for only ~5% of total open interest. BTC’s maximum pain level lies close to the current spot price, implying relatively strong gamma/pin risk; ETH’s expiry volume is half that of last week, and its current spot price sits below maximum pain—short-term implied volatility (IV) is highly likely to decline post-expiry. IV across all major maturities declined broadly: BTC IV fell below 35%, ETH IV fell below 50%, and the Volatility Risk Premium (VRP) rose slightly. On the large-trade front, whales concentrated positions in bearish put spreads (5,000-lot 75K/71K puts expiring end-May), totaling nearly $200 million in notional value. Overall, volatility expectations remain low, and market activity falls short of expectations.
