Svmuu reports that Glassnode stated on platform X that Bitcoin recently retested the $75,000 strike price. This area had previously accumulated nearly $8 billion in short Gamma positions, which once pushed BTC's price down to around $72,500 before the recent options expiry. With the large-scale options expiry concluding today, the market's Gamma structure has begun to rebuild.
Data shows that during the BTC decline, the ATM implied volatility (IV) briefly increased, with the 1-week IV breaking above 35%, before quickly falling back to approximately 32%. IV for longer tenors also declined, indicating that the market still views this volatility as a "controlled adjustment." Meanwhile, the 25 Delta Skew remains positive, around 14% across most tenors, suggesting that demand for downside protection is still higher than for call options, though it has cooled down compared to earlier this month.
Glassnode added that the 1-month realized volatility rebounded from 24.5% to 28%, while the 1-month IV remains around 35%. A premium of 7 volatility points implies that the options market is still pricing in greater future volatility.
In terms of capital flows, the buying and selling structure of options over the past 7 days is almost perfectly balanced, with the proportion of buying and selling for both call and put options close to 25%. This reflects the market's lack of clear directional bets following the recent decline.
Furthermore, demand for put option protection around the $70,000 strike price briefly rose to nearly $10 million. However, as the market rebounded, some hedging positions have begun to take profits and close out, alleviating concerns about further declines.
Glassnode concluded that market volatility has now stabilized. While hedging demand remains relatively high, it is cooling down. With the expiry of the $75,000 options, the Gamma structure of the BTC market is being re-accumulated across multiple price ranges.
