Ethereum options expiry and ETF inflow divergence

Volatility and Gamma

The massive influx of options expiration dominates the current market structure. Nearly $14 billion in options expire this week, which accounts for more than 20% of the total open interest. I see significant tension between different price targets. One researcher, Adam, reports that 100,000 BTC options expire today with a notional value of $10.9 billion and a maximum pain point of $115,000, while 690,000 ETH options expire with a notional value of $3.03 billion and a maximum pain point of $3,800. This contradicts Deribit data showing $1.27 billion in ETH contracts expiring with a maximum pain point of $3,100 and a put/call ratio of 0.74. I notice that bearish options block trading accounted for 35% of total trading volume recently, reaching a new high. Market makers face specific hedging requirements for COIN options expiring November 6, 2026, with a net gamma exposure of $15.35 per 1% move. This includes a call gamma exposure of $24.52 and a put gamma exposure of -$9.16. For the BTF expiration on November 20, 2026, the net, call, and put gamma exposures all sit at $0.

ETF Inflow Trends

ETF inflows provide a temporary cushion against this volatility. U.S. spot Ethereum ETFs recorded a net inflow of $225.8 million on Thursday, marking the largest single-day inflow since October 28, 2025. This extends a streak of nine consecutive trading days of net inflows totaling $1.42 billion since August 17. BlackRock’s ETHA accumulated $1.02 billion over this nine-day period, which accounts for approximately 72% of total inflows. Fidelity’s FETH also saw a $56.2 million inflow on Thursday, which provided the best single-day performance during this period of capital return. However, you should note that Ethereum ETFs saw $320.1 million in net withdrawals between October 12 and 16, with BlackRock’s ETHA accounting for 93% of those redemptions. The gap between Bitcoin and Ethereum inflows narrowed on Thursday, as Bitcoin ETFs saw $242.3 million in inflows compared to the $225.8 million for Ethereum. On the first day of this synchronized inflow cycle on August 17, Ethereum ETFs attracted only about one-tenth the amount of Bitcoin ETFs. Max Shannon from Bitwise Europe suggests the buying pressure comes from outside the crypto market due to increased risk appetite in traditional markets.

Price Divergence

Market sentiment remains fragmented despite these inflows. Ethereum closed at $2,477 on Friday, which shows a 5% increase over the past week. This price sits near the 200-week moving average, a level it has not returned to since breaking below it in January. I find the recent surge in South Korean demand noteworthy, as the Kimchi premium on Upbit reached 1% over the Binance price on September 1. This premium indicates a strengthening appetite for risky assets among South Korean retail investors. I also observe that Ethereum’s performance lags behind Bitcoin and more volatile tokens like SOL or XRP. Bitcoin climbed from $62,000 to over $81,000 in the past week, while Ethereum remains pressured by a lack of sustained rally after its recent surge. I also note the $11 billion of Bitcoin options expiring, which follows Bitcoin falling below $80,000 on Monday. Bitcoin prices in South Korea traded at a premium compared to global markets for about a week, which marks the longest period of appreciation seen since early May. Bitcoin fell as much as 2% Thursday and traded around $79,900 as of 8:30 a.m. in London. If spot trading volume fails to expand, the sustainability of the rally driven by ETF inflows remains questionable. Does the recent concentration of capital in BlackRock’s ETHA prevent a more diversified recovery across the Ethereum ecosystem?
