Refining takes about half the price of a $200 barrel of diesel
Diesel is above $200 a barrel in the US and Europe, and cryptobriefing.com reports the crack spread past $100 for the first time on record after six months of Strait of Hormuz disruption. The extra US fuel bill since late February is put at $100.9 billion.

What happened
- Diesel is trading above $200 a barrel in both the US and Europe after sustained disruption in the Strait of Hormuz, which carries about a fifth of world petroleum supply, since late February 2026.
- Diesel crack spreads have passed $100 a barrel for the first time in recorded history, against a peak of about $60 briefly reached in the opening months of the 2022 Russia-Ukraine war.
- Middle Eastern diesel supply losses averaged about 770,000 barrels a day from March through August, alongside roughly 350,000 barrels a day attributed to Russian restrictions.

Why it matters
- constraint A fall in crude no longer relieves a diesel buyer much, because at these levels about half the price paid sits in the refining margin and moves with distillate supply instead.
- cost Roughly $15.5 billion a month of extra fuel spending, about $7.1 billion of it diesel, comes out of US household and business budgets and is not available for anything else.
- exposure Fuel surcharges and hedges indexed to crude leave the margin component uncovered, so the buyer carries the half of the price that is moving fastest.
- precedent A $100 crack becomes the reference distillate margin the next supply disruption gets priced against, 67% above the level that stood as the modern peak.
Take the two prices as printed. Diesel above $200 a barrel against a crack spread above $100 implies crude somewhere near $100, so at these levels roughly half of what a diesel buyer pays is the refining margin [1][5][1]. Both figures are floors, and cryptobriefing.com does not print a crude price or any tanker rate, so the exact share moves with how far above each threshold the market actually sits [1][5].
The comparison the account reaches for is 2022, when diesel cracks briefly touched $60 a barrel in the opening months of the Russia-Ukraine war [6]. One hundred against sixty is 67% more [2]. That earlier move was brief by the account's own description, while this one has run through six months of disruption in a waterway that carries about a fifth of the world's petroleum [6][12][2].
The missing barrels are diesel barrels. Middle Eastern diesel supply losses averaged about 770,000 barrels a day from March through August [9]. Roughly 900,000 barrels a day moved through the corridor before the war, so about 86% of that flow is gone [3][3]. Add the 350,000 barrels a day the account attributes to Russian restrictions and the combined shortfall is about 1.12 million barrels a day [10][4].
US households and businesses have spent an estimated $100.9 billion more on gasoline and diesel than pre-war prices would have cost, roughly $46 billion of it on diesel, which is about 46% of the excess [7][8][5]. Spread across the roughly six and a half months from late February to mid-September, the total runs near $15.5 billion a month, diesel near $7.1 billion [6]. At the pump the increase works out at $2.31 to $2.79 a gallon, depending which ends of the ranges you take [4][7].
I would expect the margin rather than the crude price to set diesel for as long as distillate stocks stay thin, and the account projects global distillate inventories critically low well into 2027 [11]. Two readings cut against that. If diesel is far above $200 and not merely over it, crude can sit well above $100 and the refining share drops below half [1][5]. And if Gulf flows return toward the pre-war 900,000 barrels a day, most of the 1.12 million barrels a day now missing comes back, which would take the pressure off the crack without any change in refining capacity [3][4].
Every number here comes from a single account at cryptobriefing.com, and it gives its retail prices and percentage increases as ranges [4].
What to watch
- Whether global distillate inventories start rebuilding before the 2027 horizon cryptobriefing.com projects.
- Whether Middle Eastern diesel flows through Hormuz recover toward the pre-war 900,000 barrels a day.
- A published crude price alongside the crack spread, which would fix the refining share exactly instead of bounding it.
