Crypto traders are bracing for potential market volatility as over $4.3 billion in Bitcoin and Ethereum options contracts expire today, September 19, 2025. This expiry event comes just days after the Federal Reserve’s interest rate cut, adding an extra layer of market uncertainty.

The expiring Bitcoin options have a notional value of $3.5 billion with 30,208 contracts set to settle. For Ethereum, the expiry involves 177,398 contracts with a notional value of approximately $806.75 million.

Market data from Deribit shows that Bitcoin’s expiring options have a Put-to-Call ratio of 1.23, suggesting a slightly bearish sentiment among traders. The maximum pain level – the price at which most options expire worthless – sits at $114,000 for Bitcoin.

In contrast, Ethereum’s options show a Put-to-Call ratio of 0.99, indicating a marginally bullish outlook. Ethereum’s maximum pain point is positioned at $4,500.

Market Dynamics and Price Implications

The maximum pain concept often influences market behavior as expiration approaches. According to this theory, asset prices tend to gravitate toward their maximum pain levels. With Bitcoin trading around $117,147 at the time of writing, the price could potentially pull toward its max pain level of $114,000.

Similarly, Ethereum, trading at approximately $4,590, might experience downward pressure toward its $4,500 max pain point. However, these effects are typically short-lived, with markets usually stabilizing after traders adapt to the new price environment.

This week’s options expiry volume is similar to last week’s event when nearly $4.3 billion in options expired. The key difference this time is Ethereum’s Put-to-Call ratio dropping below 1, suggesting a shift toward more bullish sentiment for the second-largest cryptocurrency.

The balanced outlook between Put and Call options indicates traders are either speculating on further upward movement or hedging their portfolios against potential downside risks.
Data from Greeks.live indicates that options had been repricing ahead of Wednesday’s Federal Reserve interest rate decision. Implied volatility for options contracts rose while actual trading volume declined, pointing to market caution before the Fed announcement.

Upcoming Record Expiry Event

While today’s expiry is substantial, an even larger event looms on the horizon. Next Friday, September 26, will see the largest weekly Bitcoin options expiry in history, with over $18 billion in notional value set to expire.

At the current Bitcoin price level of around $118,000, over $2.4 billion worth of options are “in the money,” with a maximum pain level of $110,000. The minimal Put open interest until the $110,000 level suggests next week could bring interesting market dynamics.

The broader crypto market remains near peak levels with a total capitalization of $4.2 trillion, though it has been trading sideways since mid-July. Bitcoin is currently about 5.6% away from its all-time high, while Ethereum remains 7% below its record price.

Altcoins have performed well this week, with Hyperlink (HYPE) and Binance Coin (BNB) reaching all-time highs. Chainlink, Avalanche, and Sui have been today’s top performers, while other major altcoins have remained relatively flat.

Bitcoin futures open interest has climbed back toward all-time highs, currently standing at $86 billion according to CoinGlass data. This high level of open interest, combined with today’s options expiry, could create the conditions for short-term volatility.

For now, traders should prepare for potential price fluctuations during the early European session as the options contracts settle at 8:00 UTC on Deribit. Following this adjustment period, markets typically find a new equilibrium that could influence trading patterns into the weekend.
