The final Friday of June 2025 marks a significant event in the cryptocurrency derivatives market: the expiration of a massive volume of Bitcoin and Ethereum options. With approximately $17 billion in combined options reaching their expiry, market participants are closely watching for potential volatility and price movements in the coming hours.
This month's expiry stands out not only for its size but also because it occurs just before the end of both the quarter and the semester—two key financial milestones that often influence investor behavior across traditional and digital asset markets.
Understanding Crypto Options: Calls, Puts, and Market Impact
Options are financial derivatives that grant the holder the right, but not the obligation, to buy or sell an asset at a predetermined price before or on a specific date. In the context of cryptocurrencies like Bitcoin (BTC) and Ethereum (ETH), these instruments are widely used for hedging, speculation, and risk management.
There are two primary types of options:
- Call options: Give the right to buy an asset at a set price.
- Put options: Provide the right to sell an asset at a specified price.
Once expired, unused options become worthless. Traders who hold them must decide whether to exercise their rights based on current market conditions.
The dominant platform for crypto options trading is Deribit, which accounts for the majority of open interest in BTC and ETH derivatives. According to data shared from its official X account, over $17 billion in options are expiring today across both assets.

Bitcoin and Ethereum Expiry Breakdown
Here’s a detailed look at today’s expiry figures from Deribit:
Bitcoin: $15 billion in options expiring
- Put/Call Ratio: 0.74
- Maximum Pain Price: $102,000
Ethereum: $2.3 billion in options expiring
- Put/Call Ratio: 0.52
- Maximum Pain Price: $2,200
The put/call ratio is a key metric indicating market sentiment. A value below 1 suggests more call options (bullish bets) than put options (bearish hedges). For both BTC and ETH, ratios under 1 signal a generally positive outlook among traders.
The "maximum pain" price refers to the strike price at which the greatest number of options expire worthless, theoretically benefiting option sellers. These levels—$102,000 for BTC and $2,200 for ETH—may act as gravitational forces influencing short-term price action.
Despite other exchanges offering crypto options, Deribit remains the benchmark due to its depth of liquidity and transparency. However, total market exposure likely exceeds $17 billion when including smaller platforms.
Why This Expiry Matters: Volatility Ahead?
While options do not mandate execution, large expiries often precede increased market volatility. This phenomenon arises from several factors:
- Dealer Hedging Activity: Market makers who have sold options typically hedge their exposure by buying or selling the underlying asset. As expiry approaches, they adjust or unwind these hedges, potentially amplifying price swings.
- Position Squaring: Traders may close out positions ahead of expiry to lock in profits or limit losses, adding volume and momentum to price movements.
- Sentiment Amplification: High-profile expiries can become self-fulfilling events as traders anticipate moves around key strike prices.
Notably, this is the largest single crypto options expiry of 2025 so far, reinforcing expectations of elevated volatility. On Deribit alone, open contracts for Bitcoin surged from nearly 34,000 last week to almost 140,000 today—an explosive growth reflecting heightened interest.
Even though the put/call ratio indicates bullish bias, actual market outcomes depend on which options are exercised—not just how many exist. It’s theoretically possible that even with more calls outstanding, a sudden downturn could trigger disproportionate put usage, leading to downward pressure.
Thus, while sentiment appears optimistic, uncertainty remains high.
Broader Market Context: S&P 500 Reaches All-Time Highs
Adding another layer of complexity, traditional financial markets are also experiencing pivotal movement. The S&P 500, the benchmark index for U.S. equities, has rebounded strongly after corrections in March and April and is now flirting with new all-time highs.
Futures indicate a positive open today, suggesting strong institutional confidence and capital inflows into traditional assets. This trend has drawn speculative funds away from crypto and into equities earlier in the week—a dynamic known as "risk-on" rotation.
However, U.S. markets will be closed tomorrow for the weekend. That closure could shift capital back into the crypto market during weekend trading hours, historically known for lower liquidity and higher volatility.

Furthermore, Monday’s market reopening may bring additional volatility as traders reassess positioning across both asset classes. The confluence of crypto options expiry and macroeconomic momentum creates a fertile environment for sharp price swings.
Frequently Asked Questions (FAQ)
Q: What happens when crypto options expire?
A: When options expire, holders lose the right to exercise them unless acted upon before the deadline. Out-of-the-money options expire worthless, while in-the-money ones are typically automatically exercised on regulated platforms.
Q: Does a high put/call ratio mean the market is bearish?
A: Generally, yes. A ratio above 1 indicates more put options (bearish sentiment), while below 1 suggests more call options (bullish bias). However, actual market direction depends on broader macro factors and trader behavior.
Q: Can expired options directly move Bitcoin or Ethereum prices?
A: Not directly—but the hedging activities of market makers and large traders around expiry can influence short-term volatility and price trajectories near key strike levels.
Q: Why is this expiry considered significant?
A: At $17 billion, it's the largest crypto options expiry of 2025 so far. Its timing before quarter-end and semester-end increases institutional attention and potential rebalancing activity.
Q: How do S&P 500 movements affect cryptocurrency markets?
A: Strong performance in traditional markets like the S&P 500 can pull capital away from crypto during weekdays. Conversely, when equity markets are closed, crypto often sees increased trading volume and volatility.
Q: Where can I track upcoming crypto option expiries?
A: Platforms like Deribit publish daily reports on open interest and expiry data. Financial analytics sites also aggregate this information for broader market visibility.
Final Outlook: A Pivotal Moment for Crypto Markets
Today’s massive options expiry represents more than just a calendar event—it’s a convergence point for derivatives activity, investor psychology, and macroeconomic forces.
With bullish sentiment reflected in low put/call ratios, combined with record-level notional value expiring, Bitcoin and Ethereum are poised for potential turbulence. The interplay between dealer hedging, position unwinding, and cross-market capital flows will likely determine short-term price direction.
As always in crypto, preparation trumps prediction. Traders should monitor key levels—especially the $102,000 "max pain" for BTC and $2,200 for ETH—and remain alert to sudden shifts in liquidity.
