The crypto market is bracing for a significant derivatives event as Bitcoin (BTC) and Ethereum (ETH) approach their monthly options expiry. A total of $11.7 billion in notional value is set to expire this week, potentially triggering increased price volatility across major digital assets.
This monthly expiry—occurring on the last Friday of May 2025—falls short of the typical quarterly "max pain" events but still represents a key moment for traders and institutions monitoring market sentiment. According to Deribit, one of the leading crypto derivatives platforms, open interest has surged to its highest level since the beginning of 2025, signaling growing institutional participation and hedging activity.
Understanding the Impact of Options Expiry on Crypto Markets
Options contracts give traders the right—but not the obligation—to buy or sell an asset at a predetermined price by a specific date. When these contracts expire, especially in large volumes, they can influence short-term price action due to dealer hedging unwinds and strategic positioning around key strike prices.
For May 2025, the BTC and ETH options expiry includes:
- Bitcoin (BTC): Approximately $7.9 billion in notional value
- Ethereum (ETH): Around $3.8 billion in notional value
- Total: $11.7 billion combined
While this is smaller than the typical June quarterly expiry—which often exceeds $20 billion—the current buildup in open interest suggests that market participants are positioning aggressively ahead of potential macroeconomic shifts and regulatory developments.

Market Sentiment Ahead of Expiry
At the time of writing, Bitcoin is consolidating between $60,000 and $64,000, while Ethereum trades in the $3,200–$3,500 range. The lack of a clear directional breakout indicates investor caution, likely influenced by upcoming macro data releases and Fed policy expectations.
Deribit data shows that the largest concentration of BTC call options sits at the $65,000 strike price, followed by $70,000—suggesting bullish sentiment remains intact among long-term holders. On the put side, the $60,000 level has significant open interest, acting as a psychological support zone.
For Ethereum, the highest open interest is observed at $3,600 (calls) and $3,000 (puts), reflecting a balanced but slightly optimistic outlook despite ongoing network upgrades and competition from layer-1 alternatives.
Why Open Interest Matters
Open interest—the total number of outstanding derivative contracts—has reached multi-month highs on Deribit. Elevated levels indicate:
- Increased hedging by institutional players
- Greater market depth and liquidity
- Higher potential for volatility when positions are squared off
When large volumes of options expire out-of-the-money (OTM), dealers unwind hedges, which can lead to sharp price swings. Conversely, if prices settle near heavily concentrated strike prices ("max pain"), volatility may be temporarily suppressed.
Historical Precedents: What Past Expiries Tell Us
Looking back at previous monthly expiries in early 2025, BTC experienced average intraday volatility spikes of 6–9% in the 48 hours surrounding expiry. In some cases, such as the February expiry, price movements exceeded 12% due to cascading liquidations in leveraged futures markets.
However, markets have matured significantly since then. Improved liquidity, tighter bid-ask spreads, and more sophisticated risk management tools have helped dampen extreme moves—though sudden shifts remain possible, especially during low-volume trading windows.
One notable trend in 2025 has been the rise of structured products and zero-cost collars used by miners and funds to hedge downside risk without sacrificing upside potential. This shift could reduce panic selling during downturns but may also amplify rallies if hedges are rapidly rebalanced.
Key Factors Influencing This Month’s Outcome
Several external variables could shape how this options expiry unfolds:
- Macroeconomic Environment
Upcoming U.S. CPI and employment data may influence Fed rate cut expectations, directly impacting risk assets like BTC and ETH. - Regulatory Developments
Recent signals from U.S. regulators regarding spot Ethereum ETF approvals have boosted investor confidence. Any delays or rejections could trigger risk-off behavior. - On-chain Activity
Growing usage of Layer-2 networks and rising stablecoin transfer volumes suggest underlying demand remains strong. - Geopolitical Risk
Global tensions and central bank gold purchases continue to drive interest in decentralized stores of value.

FAQ: BTC and ETH Options Expiry – What You Need to Know
Q: What is options expiry in crypto?
A: Options expiry refers to the date when derivative contracts lose their validity. Traders must decide whether to exercise them or let them expire worthless, often leading to increased market activity.
Q: Why does $11.7 billion matter if it's not a quarterly event?
A: While smaller than quarterly expiries, monthly events still involve substantial capital reallocation. High open interest increases the likelihood of short-term volatility as market makers adjust hedges.
Q: What is "max pain" and does it apply here?
A: Max pain is the price point where the greatest number of options expire worthless, minimizing gains for option buyers. It’s often seen as a magnet for price action near expiry. Current max pain for BTC is near $65,000.
Q: How do options affect Bitcoin’s price?
A: Market makers hedge their exposure by buying or selling futures. As expiry approaches, unwinding these hedges can create buying or selling pressure, influencing price direction.
Q: Should retail investors be concerned?
A: Not necessarily. While short-term swings may occur, long-term fundamentals remain driven by adoption, regulation, and macro conditions. Staying informed helps avoid emotional decisions.
Q: Can we expect a price breakout after expiry?
A: Historically, periods following expiry see reduced volatility initially, but pent-up momentum often leads to breakouts within 3–5 days—especially if new catalysts emerge.
Strategic Takeaways for Traders and Investors
As the May 2025 options expiry approaches, market participants should:
- Monitor key strike prices ($60K/$65K for BTC; $3K/$3.6K for ETH)
- Watch for changes in open interest and implied volatility
- Avoid excessive leverage during the expiry window
- Use the event as an opportunity to reassess portfolio hedges
Institutional-grade traders are increasingly using options to express nuanced views on market direction—ranging from straddles anticipating volatility to iron condors profiting from range-bound action. For retail users, understanding these dynamics offers valuable insight into probable price behavior.

Final Thoughts: A Signal, Not a Catalyst
While the $11.7 billion BTC and ETH options expiry is unlikely to single-handedly reverse market trends, it serves as a critical inflection point. The confluence of high open interest, uncertain macro signals, and evolving regulatory landscapes creates fertile ground for surprise moves.
Rather than viewing this event in isolation, investors should consider it part of a broader narrative—one shaped by adoption curves, technological progress, and shifting institutional appetite.
By staying informed and avoiding reactionary trades, both novice and experienced market participants can navigate this expiry with greater confidence.
