Exxon shuts major Midwest refinery amid 90% diesel price surge

Summary

Exxon Mobil has shut one of the largest Midwest refineries, producing ~11 million gallons of gasoline and diesel per day, due to an outage. With U.S. diesel prices already up ~90% YTD and entering peak demand season, this is a material regional supply shock likely to lift distillate cracks, RBOB/ULSD futures, and Midcontinent basis levels.

Details

  1. What happened: Exxon Mobil has taken offline one of the largest diesel refineries in the U.S. Midwest because of an outage. The facility reportedly produces around 11 million gallons per day of combined gasoline and diesel – roughly 260,000 bpd equivalent. The shutdown comes as U.S. diesel prices have already surged nearly 90% this year and the market is entering peak seasonal demand for heating oil and agricultural use.

  2. Supply/demand impact: Assuming 260 kb/d throughput with ~40–45% middle distillate yield, the outage likely removes on the order of 100–120 kb/d of diesel and 90–110 kb/d of gasoline from supply, heavily concentrated in PADD 2 (Midwest). In a tight distillate market, this is a meaningful marginal loss and will further pressure inventories and crack spreads. On the demand side, no destruction is implied; the effect is primarily supply-side tightness and logistical dislocation as barrels are rerouted from Gulf Coast and Canada.

  3. Affected assets and direction: The most direct impacts are bullish for NY Harbor ULSD futures, Chicago diesel and gasoline cash differentials, and Gulf Coast–Midwest pipeline spreads (e.g., Line 61, Explorer). RBOB futures may also firm on knock-on gasoline tightness. Refining margins for unaffected Midcon and Gulf Coast refineries should expand. Broader crude benchmarks (WTI, Brent) could see modest support if the outage is prolonged, but the effect there is secondary and may be tempered if reduced runs translate into lower crude intake in the short term.

  4. Historical precedent: Similar unplanned outages at large U.S. refineries (e.g., BP Whiting 2015, Bayway or Baton Rouge incidents) have triggered multi-percent intraday moves in regional cracks and distillate futures, especially when coinciding with low inventories and strong demand.

  5. Duration of impact: Key unknowns are cause and expected downtime. A multi-day outage mainly drives regional price spikes; a multi-week or longer disruption would have broader national implications for diesel balances and could sustain elevated ULSD cracks through harvest and early heating seasons. Until guidance from Exxon emerges, markets will likely price in at least a near-term tightening bias.

AFFECTED ASSETS: NY Harbor ULSD futures, RBOB gasoline futures, WTI futures, Midwest diesel basis (Group 3, Chicago), Midwest gasoline basis, Refining margin crack spreads (HO/WTI, RBOB/WTI), US diesel crack spreads ETFs/refiner equities
