August 15 Sees $6 Billion in Crypto Options Expiry

A considerable round of crypto options expired on August 15, highlighting a surge in institutional activity and notable shifts in market sentiment. 39,000 BTC options contracts and 280,000 ETH contracts expired , with combined notional value nearing $6 billion. These expirations represented approximately 9% of the current open interest.

At the same time, exchange Deribit reported a record-breaking $10.9 billion in daily trading volume on Thursday, its first day of operations under new ownership. The data points to increased market engagement following a week in which Bitcoin hit a new high and Ether approached its all-time peak of $4,800.

BTC Options Expiration and Trading Activity

Bitcoin options ended the week with 39,000 contracts expiring, with a notional value of $4.6 billion. The Put Call Ratio stood at 0.95, denoting near-equal bearish and bullish consideration.

Further, the maximum pain point for BTC options was set at $118,000; however, the implied volatility has been skewed lower, with short- and mid-term IVs coming below the 35% mark. Hence, the short term risk has been priced conservatively according to those participants looking at expiration.

Meanwhile, bullishness in the BTC sentiment stands further reinforced as the asset reached new highs earlier in the week. This price movement brought forth increased trading volumes across major venues. More importantly, Deribit recorded an unprecedented $10.9 billion volume this on Thursday. This record achieved in a single day slightly precedes, and may be indicative of increased institutional interest in digital asset derivatives following the acquisition of the platform.

Ethereum Options Data and Volatility Trends

Ethereum experienced even larger contract expiries, with 280,000 ETH contracts expiring and a total notional value of $1.3 billion. The Put Call Ratio for ETH was slightly higher at 1.04, showing a marginal tilt toward protective positions.

Meanwhile, the Max Pain point remained at $4,000, below the recent price level of the asset. Ethereum almost hit its all-time price high of $4,800 during the week, thereby cementing higher-than-average volumes.

On the diagonal volatility surface, Ethereum held substantially higher implied volatility levels compared to BTC. Main-term implied volatility for Ethereum remained at the 70% mark, with similar expectations for price jumps. This implicit vol contrast between BTC and ETH, thus, suggests contrary market expectations even though the bullish momentum in both spot markets has run parallel.

More Block Trading and Bull Spreads

Both bullish and bearish block trades have gained momentum throughout such weeks, reflecting a growing divergence in trader positioning across the derivatives market. Moreover, the market has shown interest in structured strategies, with bull spread positions in particular, notably the 4800/5000 strike on ETH , becoming cheap choices for some traders.

The concentration of these activities within this narrow range signals that market makers are positioning for large but controlled price movement. At the same time, the increased block trade volume highlights deeper liquidity and tactical deployment of capital around expiration events.
