The cryptocurrency derivatives market has entered a new phase of maturity and institutional adoption, highlighted by Deribit's bitcoin options open interest surpassing $4 billion—a record high. This milestone was reached just ahead of the largest quarterly expiry of 2025, during which 139,000 BTC and 939,000 ETH options contracts were settled on a single Friday. The event marked a pivotal moment for market structure, signaling growing confidence and participation from sophisticated traders and institutions alike.
Deribit continues to dominate the crypto options landscape, accounting for nearly 90% of all bitcoin options open interest across exchanges. Industry data shows total options open interest across all platforms now exceeds $4.5 billion, underscoring the increasing demand for leveraged and hedging instruments in digital asset markets.
Record-Breaking Quarterly Expiry Fuels Market Activity
On the key expiry date of June 27, approximately $750 million in notional BTC volume was settled through options contracts. The final put/call ratio closed at 1.02, reflecting a slight tilt toward bullish sentiment. This ratio is critical for gauging market positioning—values above 1.0 typically suggest more puts (bearish bets) than calls (bullish bets), but in this case, the balance indicated traders were well-hedged with a marginal lean toward upside protection.
The maximum pain price—the strike price at which the greatest number of options expire worthless—was set at $105,000 for bitcoin. This level serves as a psychological and structural anchor, often influencing spot price behavior around expiry as market makers adjust hedges.
For Ethereum, the story was similar but with different dynamics. A total of 939,000 ETH contracts, representing $229 million in notional value**, expired. The put/call ratio settled at **0.52**, indicating significantly more call volume, which aligns with strong bullish positioning. The maximum pain price for ETH was near **$2,200, slightly below the prevailing market price at expiry.
Post-Expiry Price Action: Bitcoin Holds Strong, Altcoins Wobble
Following the massive settlement, price reactions diverged across assets. Bitcoin stabilized around $106,800**, demonstrating resilience and underlying demand. In contrast, Ethereum dipped nearly **2% to $2,440, dragging many altcoins lower in its wake.
Indices like the GMCI 30, which tracks major altcoins, showed increased volatility. Assets including XRP, SOL, and ADA faced downward pressure, though analysts attribute this more to technical rebalancing than broad-based fear or capitulation.
Timothy Misir, Research Head at BRN, noted that the divergence between BTC and ETH performance reflects differing volatility expectations. "Bitcoin’s implied volatility (IV) has dropped below 35% across short to mid-term expiries, while Ethereum’s IV has surged to 65%, with intra-day swings exceeding 30%," he explained in a recent report.
"This suggests the market views Bitcoin as relatively stable—almost a 'digital gold' underpinning the ecosystem—while Ethereum remains priced with higher uncertainty, despite persistent institutional interest."
Institutional Tools Reshape Derivatives Landscape
One of the most significant developments fueling this maturation is the integration of real-world assets (RWA) into crypto trading infrastructure. Earlier this month, Deribit—and spot exchange Crypto.com—began accepting BlackRock’s tokenized U.S. Treasury fund (BUIDL) as collateral for margin accounts.
This move allows traders to use a regulated, yield-generating digital asset backed by U.S. government debt to secure leveraged positions. It reduces reliance on traditional stablecoins and introduces a low-volatility collateral option that appeals to institutions wary of crypto-native assets’ price swings.

The BUIDL fund, built on blockchain infrastructure and secured via cold wallet hardware integration, offers daily yield accrual and full redemption rights. For professional traders, this means they can maintain exposure to volatile crypto assets while minimizing capital costs and counterparty risk.
Coinbase’s Potential Acquisition of Deribit: A Game Changer?
Adding further momentum to the sector, Coinbase announced plans to acquire Deribit for $2 billion, with an expected closing date in 2025. While regulatory approvals are still pending, the deal could dramatically reshape the competitive landscape of crypto derivatives.
If completed, the acquisition would allow Coinbase to integrate one of the most advanced options platforms into its ecosystem, combining robust spot trading with deep derivatives capabilities. It also positions Coinbase to lead in hybrid financial products—blending traditional instruments like tokenized bonds with cutting-edge crypto derivatives.
Such convergence is emblematic of broader trends: digital assets are no longer speculative playgrounds but evolving into serious financial infrastructure.

Frequently Asked Questions (FAQ)
Q: What does 'open interest' mean in crypto options?
A: Open interest refers to the total number of outstanding options contracts that have not been exercised or expired. Rising open interest often indicates growing market participation and liquidity, especially when aligned with price trends.
Q: Why is Deribit so dominant in bitcoin options?
A: Deribit pioneered crypto-native options trading with deep liquidity, advanced trading tools, and frequent settlement cycles (weekly and quarterly). Its focus on professional traders and institutional clients has helped it capture over 85% of the BTC options market.
Q: What is the significance of the put/call ratio?
A: The put/call ratio compares the volume of bearish (put) options to bullish (call) ones. A ratio near 1 suggests balanced sentiment; above 1 indicates more downside hedging; below 1 reflects stronger bullish positioning.
Q: How do tokenized U.S. Treasuries benefit crypto traders?
A: They offer a stable, yield-bearing collateral option backed by real-world assets. Traders can post them as margin instead of volatile cryptocurrencies or centralized stablecoins, reducing risk and improving capital efficiency.
Q: What happens during a 'quarterly expiry'?
A: On set quarterly dates (March, June, September, December), large volumes of options contracts expire simultaneously. This often triggers significant hedging activity and can influence short-term price movements due to dealer rebalancing.
Q: Could Coinbase’s acquisition of Deribit affect market competition?
A: Yes. Combining Coinbase’s global reach and compliance framework with Deribit’s leading derivatives engine could create a dominant player in crypto trading—potentially raising regulatory scrutiny but also accelerating product innovation.
