Ethereum's native token, Ether (ETH), slid to around $2,100 on Monday, extending its recent underperformance as a sharp rally in crude oil prices rekindled inflation concerns across global markets. The decline came amid heightened geopolitical tensions in the Middle East, including drone attacks in the Gulf and a partial closure of the strategic Strait of Hormuz, which together pushed Brent crude above $110 per barrel and U.S. crude to $106.72.
Fundstrat Global Advisors co-founder Tom Lee highlighted the growing inverse relationship between Ether and oil, calling the surge in crude prices the single biggest near-term headwind for Ethereum. In a post on X (formerly Twitter), Lee noted that ETH is currently exhibiting its most pronounced negative correlation with oil on record. When two assets are negatively correlated, they tend to move in opposite directions; in this case, rising oil prices are dragging down Ether.
Ether was last trading at $2,115, down 3.5% on the day, while Bitcoin (BTC) slipped 2.1% to $76,784. The broader crypto market also felt the sting of risk-off sentiment, with major altcoins posting losses. The sell-off was compounded by continued outflows from spot Ethereum exchange-traded funds (ETFs), whale selling, and a general shift away from speculative assets.
Lee, however, characterized the current move as “short-term tactical noise,” suggesting that a retreat in oil prices could pave the way for a rebound in Ether. He pointed to long-term catalysts such as tokenization—the process of putting claims on funds, property, or securities onto a blockchain—and the rise of agentic artificial intelligence (AI), software capable of acting or making payments on behalf of users, as key drivers for Ethereum in 2026.
Beyond oil, Ethereum faces multiple macro and technical pressures. Andri Fauzan Adziima, research lead at Bitrue Research Institute, told Cointelegraph that while crude is a key macro headwind, other factors include ETF outflows, an increase in the supply of coins on exchanges, whale selling, diminished risk appetite, and Ether’s persistent underperformance relative to Bitcoin. The gap between the two largest cryptocurrencies is significant: Bitcoin remains the primary liquidity anchor for crypto investors during times of stress, while Ether behaves more like a high-beta risk trade, making it more sensitive to macro selling and doubts about institutional demand.
The energy shock is not limited to crypto. U.S. President Donald Trump posted on Truth Social Sunday that “the Clock is Ticking” on Iran, escalating fears of a prolonged diplomatic standoff and a sustained energy crisis. Stock markets also wobbled, with the S&P 500 and Nasdaq both in negative territory as bond yields rose on inflation expectations.
ING commodities strategists Warren Patterson and Ewa Manthey warned in a note that “re-escalation risks are increasing,” adding that while shipping activity near the Strait of Hormuz has picked up, conditions could shift rapidly. A prolonged closure of the strait, which typically handles about 20% of the world’s oil and gas trade, could keep energy prices elevated and bond yields high, making it even harder for speculative assets like Ether to attract fresh capital.
For now, traders are watching whether crude can retreat from current highs. If oil remains above $100, Ether could test the $2,000-$2,100 support zone. Conversely, a drop in energy prices could provide the relief needed for a recovery. Lee remains optimistic on Ethereum’s longer-term prospects, but the immediate path depends heavily on the direction of oil and the resolution of geopolitical risks in the Gulf.
