26th September 2025 – (New York) Digital asset markets experienced a pronounced downturn, with Bitcoin and Ether leading declines ahead of a substantial options expiry event. The broader sell-off has erased over $140 billion in market capitalisation this week, reflecting a shift away from riskier investments.
Ether fell sharply, dropping as much as 8.2% to breach the $4,000 threshold for the first time in nearly seven weeks. Bitcoin concurrently declined approximately 3.3%, falling below $110,000. More speculative tokens, including Dogecoin and Cronos, registered steeper losses, declining by up to 9.4% and 10% respectively.
Market analysts attribute the weakness to a broad-based de-risking trend. “Assets without strong fundamentals, such as memecoins, are typically the first to be impacted and exhibit greater volatility,” noted Lex Sokolin of Generative Ventures. He suggested that previous positive catalysts, including regulatory developments and interest rate cuts, have already been factored into market prices.
The market faces a significant test with the impending expiry of derivatives contracts representing approximately $17 billion in Bitcoin and $5.3 billion in Ether open interest. This volatility was initially triggered by the liquidation of $1.7 billion in bullish positions, followed by an additional $1 billion in forced closures on Thursday, highlighting the susceptibility of cryptocurrency markets to cascading sell-offs.
According to Rachael Lucas, an analyst at BTC Markets, Ether’s decline coincides with cooling institutional inflows and technical indicators suggesting further short-term pressure. A sustained drop below $3,800 could precipitate additional liquidations. This trend is reflected in outflows from US-listed Ether exchange-traded funds, which have seen nearly $300 million withdrawn since Monday.
The downturn also affects publicly-listed companies that maintain significant cryptocurrency treasuries, whose shares often trade as leveraged proxies for underlying digital assets. Shares of Bitmine Immersion Technologies Inc. and SharpLink Gaming Inc. each fell more than 8%.
Despite the current volatility, Bitcoin and Ether remain among the top-performing major assets this year. However, as Tony Sycamore, analyst at IG Australia, observed, a daily close below $4,000 for Ether could signal a further decline toward the $3,700-$3,500 range.
