Ether (ETH) has dipped to $2,111, falling -9.1% in seven days, as per data from CoinGecko at the time of writing. The low of $2,104 touched the dotted horizontal support visible on the daily chart, a level that has now absorbed multiple tests since the February 2026 recovery began.
Fundstrat’s Tom Lee, writing on X on May 18, identified rising oil prices as the primary reason for ETH’s sustained selling pressure and published two Bloomberg charts to support the case.

If one is wondering why Ethereum $ETH has been under selling pressure:– to me, rising oil prices is the biggest headwind
– ETH inverse correlation to oil is the highest ever pic.twitter.com/G5Uw0wbtJP— Thomas (Tom) Lee (not drummer) FundstratDirect.com (@fundstrat) May 18, 2026
Lee’s first chart, built on Bloomberg data covering April 23, 2016, through May 18, 2026, shows the rolling daily correlation between ETH and oil prices.
The correlation has reached approximately -0.40, the most negative reading in the data set, indicating that ETH and oil are moving in opposite directions more sharply than at any prior point in ETH’s trading history. Every previous spike in negative correlation resolved with a return toward zero. The current reading has moved further into negative territory than any of those prior events.
The second chart maps the relationship in real time from April 7 to May 17, 2026, overlaying CME Ether futures on an inverted y-axis against WTI oil futures. WTI rose to $107.73 from about $80 over that six-week window. ETH fell to $2,114.50 from above $2,400 across the same period.
The two lines track with such precision that the relationship is difficult to dismiss as a coincidence. “As oil rose in the past 6 weeks, ETH prices have fallen,” Lee wrote. “Oil reversing = ETH prices recovering.”
Lee’s post also addressed the forward view. “This is short-term tactical noise. The bigger driver for ETH is: tokenization [and] agentic AI. These structural drivers are in place. Thus, we expect ETH prices to be stronger as we move through 2026.”
The oil-as-headwind thesis carries a clear implication for positioning: Ether’s near-term path is more sensitive to macro energy dynamics than to any protocol development or institutional deployment catalyst.
BlackRock’s BSTBL OnChain shares, J.P. Morgan’s JLTXX, Fidelity International’s FILQ, and Bitmine’s 5.18-million-ETH treasury all landed in the past 10 days without interrupting the decline. The correlation regime, not the fundamental backdrop, has been pricing ETH since April.
Data and charts from TradingView show the full cycle from December 2024 through May 2026. The August 2025 peak near $4,800 and the February 2026 trough near $1,750 bracket the current range.
ETH recovered to $2,400 in April before the oil-correlation-driven decline returned the price to the dotted horizontal support zone at $2,100-$2,150. The $2,104 low from May 18 is the most significant test of that zone yet.
Every moving average (MA) on the indicator panel signals a sell. 10-day exponential moving average (EMA10) at $2,220, 10-day simple moving average (SMA10) at $2,250, EMA20 at $2,256, SMA20 at $2,280, EMA30 at $2,262, SMA30 at $2,294, EMA50 at $2,258, SMA50 at $2,260, EMA100 at $2,326, SMA100 at $2,150, EMA200 at $2,559, SMA200 at $2,593: All 11 sit above the current price and register sell signals. Hull, MA, at $2,115, is the only average within $4 of the current price. The Ichimoku baseline at $2,260 remains neutral.
The oscillator stack reflects the depth of the decline. The relative strength index (RSI) is at 33.93 and sits four points above the traditional oversold threshold of 30, the closest it has been since February’s trough.
Stochastic %K at 7.25 has entered deeply oversold territory, where mean reversion has historically followed. Williams’ %R at -95.20 corroborates the reading.
The commodity channel index (CCI) at -220.47 is so extreme that it registers a buy signal on the indicator panel despite the broader sell environment. With the moving average convergence/divergence (MACD) at -29.85 and momentum at -194.34, both signal active selling pressure.
The average directional index (ADX) at 19.83 stays below 25, confirming the current decline lacks the velocity of a trend breakdown.
The oil correlation provides the most actionable forward signal in Lee’s framework. WTI at ~$103 has risen amid Hormuz disruptions linked to Iran’s and the UAE’s departure from OPEC. A ceasefire extension or supply resolution that brings WTI back toward $90 would correspond to an ETH recovery toward $2,300-$2,400, according to the correlation Lee identified.
The correlation is inverse: The path back to $2,400 runs through oil, not through the next Ethereum protocol upgrade.
Stochastic %K at 7.25 and RSI at 33.93 have entered the territory where the May 2026 decline exhausts mechanical selling. Both readings were comparable at the February 2026 trough, which preceded a recovery of more than 30%. The structural drivers Lee cited, tokenization and agentic AI, supported that recovery.
