Diesel Cracks Blow Past $1 a Gallon for the First Time in Over a Year as Russian and Mideast Outages Bite

The margin a refiner earns for turning a barrel of crude into diesel just crossed a line it had not touched in more than a year. Between mid-October and mid-November, diesel crack spreads at New York Harbor, on the U.S. Gulf Coast and at the Amsterdam-Rotterdam-Antwerp hub all pushed above a dollar per gallon at the same time. The Energy Information Administration flagged the move in its late-November note on elevated diesel prices, calling it the highest level all year. Two forces did it: refineries knocked offline in Russia and the Middle East, and a fresh round of U.S. and EU sanctions on Russian crude that landed in the same three weeks.

A crack spread is the plain-language version of a refiner's paycheck. Take the price of the finished fuel, subtract the price of the crude that went into it, and what's left is the margin. When diesel cracks run above $1 a gallon across three separate pricing points on both sides of the Atlantic, the market is telling you the same thing in three languages: there is not enough diesel to go around, and whoever can make it is getting paid.

What actually broke

Start with Russia. Ukraine spent the back half of 2025 hitting Russian refineries and export terminals with long-range drones, and the damage stopped being a rounding error. BBC Verify's reporting put the tally at 21 of Russia's 38 large refineries struck at least once since January. At the peak of the campaign in the August-to-October stretch, roughly 20% of Russian refining capacity was offline at various points. Reuters later found the full-year hit to actual throughput was smaller than the headline outages suggested, a few percentage points, because Russia leaned on spare capacity. But the timing is what mattered. The strikes bit hardest exactly when the rest of the world was already short.

Then the Middle East pitched in. Kuwait's Al-Zour refinery, a 615,000 barrel-a-day plant that is one of the region's largest, shut units after a fire in late October. The outage was first expected to clear by early November. It didn't. Energy Intelligence reported it could stretch into December, and Kuwait Petroleum ended up selling crude cargoes to Asia that it could no longer process at home. Al-Zour is a serious diesel and fuel-oil exporter, so losing it for weeks pulled real barrels out of the seaborne market at the worst possible moment.

Layer on the refinery maintenance season, which runs heavy in autumn as plants swap over to winter fuel, and add mixed signals out of Nigeria's giant Dangote refinery, and the supply side of the diesel balance was leaking from several holes at once.

The sanctions that tightened the screw

The outages set the stage. Sanctions kicked the door in. On October 22, after U.S. markets closed, the Treasury's Office of Foreign Assets Control put Rosneft and Lukoil, Russia's two largest oil companies, on its Specially Designated Nationals list under Executive Order 14024. The UK moved against the same targets, and the EU tightened its own restrictions on Rosneft, Lukoil and Gazprom Neft in October. Brent traded up about 5% the next morning.

Here is why sanctions on crude showed up in diesel margins. The October measures were aimed at the refiners in India and Turkey that had been buying discounted Russian crude and selling the finished products, including diesel, back into the world market. Choke off the crude those plants run, and you choke off the diesel they export. Indian refiners paused Russian buying as they worked out what the sanctions meant for them. That is barrels of product supply going dark, not because a refinery burned down, but because the crude feeding it became too hot to touch.

Why the same number showed up in three places

The striking part is not that one market got tight. It's that New York Harbor, the Gulf Coast and ARA all crossed a dollar together. Diesel is the most globally traded of the major fuels. Cargoes move freely across the Atlantic, so a shortage in Europe pulls barrels off U.S. docks, which tightens U.S. supply, which lifts U.S. prices until the arbitrage closes. When Russian and Middle Eastern product both vanish from the Atlantic Basin at once, there is no slack anywhere to paper over the gap. The three hubs move as one because, for diesel, they basically are one.

The Gulf Coast 3-2-1 crack spread, a rough proxy for overall refining margin that assumes three barrels of crude yield two of gasoline and one of distillate, ran north of $31 a barrel by mid-November. And that was the muted version. With gasoline demand seasonally soft, the diesel component was doing almost all the lifting. Refiners were, in effect, running crude to chase the diesel and tolerating the gasoline as a byproduct.

What it means for the people paying for it

Diesel is the fuel of the physical economy. It moves the trucks, the trains, the tractors and the construction equipment, and in much of Europe it heats homes as heating oil, which is chemically the same product. A dollar-plus crack does not stay bottled up at the refinery gate. It flows into freight rates, into farm costs and, in the Northeast and across Europe, into winter heating bills, right as the cold sets in.

For refiners, this is the kind of quarter that pays for a lot of lean ones. Anyone with a complex plant running full tilt through the autumn caught a margin they hadn't seen since 2024. The catch is that these spreads are built on disruption, not on healthy demand, and disruption is fickle. When Al-Zour comes back, when the Russian outages get patched, when Indian and Turkish refiners find a workaround to keep the product flowing, the extra supply lands on a market that has been running on fumes, and margins can give it all back in a hurry.

Where it goes from here

Two things will decide whether diesel cracks hold above a dollar into winter. The first is Russian repair speed against continued Ukrainian strikes. So far the drones have kept pace with the wrenches. The second is how hard the October sanctions actually bite once OFAC's general licenses and the wind-down periods play out, and whether Indian and Turkish buyers stay on the sidelines or quietly find their way back. If the outages linger and the sanctioned crude stays stranded, low diesel inventories heading into the coldest months are a recipe for spikes that make mid-November look calm.

The honest read is that the market has almost no cushion. When margins are this fat across three continents at once, it is not a sign of strength. It's a sign the system is running with nothing in reserve, and everyone in the diesel chain, from the refiner booking record cracks to the trucker filling up at dawn, is one more outage away from finding out how thin the margin for error has gotten.
