Refiners Run the Table

Crude is the headline. Diesel is the money.

Goldman Sachs this week told clients that refining margins will stay two to three times higher than the 2013-2019 average through the rest of 2026, with diesel cracks especially elevated. Diesel margins are running $19 to $26 per barrel above March levels, and the bank sees U.S. refiners capturing $50 per barrel by the fourth quarter. That margin is triple what refiners earned in a normal pre-war year, and it's structural, not a spike.

The products market is where the Hormuz crisis actually lives.

Global refined product exports are down 4 million barrels per day from pre-war levels. War-related outages shut in 2.5 million barrels per day of Middle East refining capacity. Russian diesel output fell 10% in May after a 10% drop in April, the result of relentless Ukrainian drone strikes on refineries. Moscow this week banned jet fuel exports through November.

The market is tighter than the crude balance suggests. Refiners can't make product as fast as demand recovers, and Goldman expects diesel and gasoline stocks to keep falling even as Hormuz gradually reopens. Crude might be available. The conversion capacity isn't.

This is the real supply shock — not the barrel coming out of the ground, but the barrel that can't be turned into fuel. Goldman projects European diesel margins at $37 per barrel in Q4, with gasoline at $14 in Europe and $22 in the U.S. The refining system is broken in two places at once: Gulf capacity offline from the war, Russian capacity under attack. Those are the world's two largest product exporters, and both are bleeding.

The diesel crack hasn't just widened — it's inverted the usual logic of an oil rally. Refiners with access to crude and intact facilities are capturing margins that would normally accrue to producers. Crude rallied 7% this week, but the crack spread rallied harder.

• Diesel export loss: 4 million barrels per day of global refined products offline, with Middle East and Russia accounting for most of the damage.
• U.S. refiner margins: $50 per barrel for diesel by Q4, more than triple the pre-war norm and 60% above current European levels.
• Russian capacity under fire: back-to-back 10% monthly declines in diesel output as Ukraine hits refineries; jet fuel exports now banned through year-end.

The products market is pricing scarcity that the crude market is still figuring out. Every cargo of Brent that reaches a healthy refinery is worth more than the same barrel sitting in storage. Crack spreads are the new call option on the Hormuz reopening timeline. If the strait stays closed longer, margins stay wide. If it opens but refinery damage lingers, margins stay wide. The only scenario that collapses the spread is a full and fast normalization — and Goldman's forecast suggests the bank isn't pricing that.

Refiners with run capacity and feedstock access just became the highest-margin players in the oil complex.
