WTI closed at $69.60 on July 6. Brent closed four cents below it. Speculative money agrees with the calm: managed-money net length in WTI futures sits at +64,000 contracts, the bottom 5% of every weekly print since 2010. By every upstream measure this is a quiet, well-supplied, faintly bearish oil market.
Downstream, the same barrel is on fire. Our Gulf Coast 3-2-1 crack, the spot margin for turning three barrels of WTI into two of gasoline and one of diesel, printed $60.63 the same day. Across 10,054 trading days since 1986, that is the 99.8th percentile. The long-run median is $7.28. Two days later the futures version settled at $64.58, the highest in the contract's history, and Commodity Context's Rory Johnston watched the diesel leg jump $10 a barrel in a single morning. Issue No. 1 was about diesel. The diesel story has spread to the whole barrel.
Two facts from our series:
- The composite margin is up 55% in thirty days: under $40 in the first week of June, $60.63 on July 6. WTI went nowhere in the same window. Every dollar of that move is refining scarcity, not crude.
- In forty years of data, only nineteen days ever printed higher: sixteen in the spring and autumn of 2022, in the first months of the invasion; two in September 2008, the week Hurricane Ike shut the Gulf Coast; one in April 2020, the week WTI collapsed. Margins in this territory have always required a war, a hurricane, or a broken crude contract. This is the first time they have arrived while crude slept.
Not a diesel story anymore
What separates July from the spring is the gasoline leg. The Gulf Coast gasoline crack printed $58.42 on July 6, the 99.9th percentile of every trading day since 1986. It is up more than 80% in a month. The handful of days above it reads like a disaster almanac: Hurricane Rita in 2005, Ike in 2008, the April 2020 crude collapse, and the early-invasion summer of 2022. Nothing else in the record comes close.
The same signal is printing abroad. European gasoline traded about $41 over crude in early July, the widest since the summer of 2022. And it is printing across every product at once. In our series the Gulf jet crack sits at the 97.7th percentile, and Issue No. 1's diesel benchmark, NY Harbor No. 2 over Brent, at the 99.5th. All four legs of the barrel above the 97th percentile at once is not a product dislocation. It is a complex-wide margin regime.
The refining system's answer has been to run flat out: 95.8% utilization on July 3, the 97th percentile of the last five years, with crude inputs averaging 17.0 million b/d. It did not help. In the July 8 report week, analysts expected a ~900,000-barrel distillate build and got a 5.0-million-barrel draw; gasoline fell 1.9 million barrels alongside. Our weekly series has gasoline stocks at 212.1M barrels, 6.9% under the five-year seasonal average, and distillate at 103.6M, 12.8% under. Running the fleet at the 97th percentile did not build a single barrel of the two products the market is paying for.
The jet paradox
The scarcity has a mirror image, and it is the strangest chart on the desk. Distillate stocks sit in the bottom decile of every week since 1982; the May prints were the lowest since 2003. U.S. jet fuel stocks are at the *99.2nd percentile: 47.6M barrels, 10.4% above the seasonal average*. The June 26 print of 48.0M was the highest weekly reading since September 2010.
The two anomalies are the same anomaly. When the spring's Strait of Hormuz disruption cut Persian Gulf jet exports, the Gulf Coast jet crack tripled from $0.42/gal in January to $1.25 by spring, and U.S. jet output crossed 2.0 million b/d for the first time on record. Kerosene and diesel are adjacent cuts of the same column. In normal times refiners blend kerosene down into the diesel pool. At a $1.25 jet crack they stopped, and certified every available molecule as Jet A-1. The diesel pool starved to feed the jet tank. The export system could not clear the jet fast enough, so it piled up at home.
Why not simply swing back? Because the swing has a hard ceiling. Hydrocracking catalysts can shift the middle-distillate cut by roughly 5–10 percentage points before over-cracking loads the product with polynuclear aromatics, which wreck the freeze-point spec that keeps jet fuel liquid at −40°. Beijing, for its part, ordered its majors to maximize gasoline and diesel yields outright. The system is pinned. It cannot rebuild diesel without surrendering the jet margin. It cannot push jet yields further without ruining the batch.
The margin is Atlantic
Global averages hide where this hurts. Northwest Europe lost its largest diesel supplier: Russian seaborne exports fell from a 2025 average of roughly 817,000 b/d to about 234,000 in the first ten days of July, and on July 8 Moscow banned diesel exports outright. Low-sulphur gasoil futures hit a record $60.77 premium to Brent. Regional middle-distillate inventories sit about 20% below their seasonal range. The ICE gasoil crack is holding near $48 against a pre-war habit of $20–25.
Singapore tells a different story. Gross refining margins there climbed from $5 in late February to about $21: a four-year high anywhere else, a third of Atlantic levels today. The difference is China. Beijing held first-batch export quotas to a restrictive 19 million tons, over 70% of it to Sinopec and CNPC. Then export margins neared 1,000 yuan ($147) a ton, and Beijing lifted the curbs for July: roughly 3 million tons is coming out, including 1.9 million tons of jet, 600,000–700,000 of diesel, and over 400,000 of gasoline. That flow is the buffer keeping Asian cracks civilized. The most bearish lever over this entire regime is whether the August batch keeps it open.
The cavalry is late
The reason a products squeeze becomes a products era is on the capacity chart. U.S. operable distillation capacity stands at 18.02 million b/d, 5.1% below the May 2020 peak and down another 145,000 b/d in the past year. The fleet keeps shrinking. Grangemouth stopped processing crude. Shell ended crude runs at Wesseling in March 2025. Valero shut Benicia at the end of April; with the Phillips 66 Los Angeles closure, that removes 17% of California's refining. One reversal proves the rule: BP put its planned one-third cut at Gelsenkirchen on hold because the diesel market got too tight to walk away from.
The replacements exist on paper. Dangote's crude unit is running at 700,000 b/d, briefly the largest single train on earth, and met nearly 80% of Nigeria's April petrol demand. But the 200,000 b/d cat cracker that makes export-spec gasoline at scale has been the plant's bottleneck since April 2025, its restart dates slipping through the first half of this year. China's Yulong is targeting full integration in Q2. Mexico's Dos Bocas averaged 175,800 b/d in Q1, 52% under design, with four safety incidents in 23 days. Only Kuwait's Al-Zour and Oman's Duqm are delivering baseload. Net it out and Industrial Info projects global capacity growing about 620,000 b/d a year through 2027, against demand growth of 1.0–1.5 million. The additions are real. They are simply later than the closures, and mostly on the wrong ocean.
The coiled spring
Here is the asymmetry worth sitting with. A refined product's price is crude plus crack. The crack is at the 99.8th percentile. The crude beneath it is priced for a glut: speculators' net length sits in the bottom 5% of sixteen years of weekly prints, and Commodity Context's latest positioning read has them still selling crude into the bounce. Sanctioned crude that Russia cannot refine still reaches the water. So products are carrying record margins on top of depressed crude. If crude stays asleep, refiners keep printing. If anything wakes it, the crack does not have to compress for pump prices to jump; the floor rises underneath them. Goldman has already abandoned its glut call on prolonged Gulf disruptions. Equity desks have noticed: Morgan Stanley just revised large-cap refiner EBITDA up 7% and upgraded Phillips 66. The EIA's STEO argues the opposite corner: cracks narrowing after the driving season, retail gasoline near $3.40 by Q4 and under $3.10 next year.
Autumn's deferred bill
The margin regime is eating its own maintenance schedule. U.S. refiners took only about 470,000 b/d offline this spring, versus 700,000 last year and 900,000 in 2024. Motiva pushed the Port Arthur crude-unit turnaround out to fall 2027; Port Arthur is the largest refinery in North America. Unplanned Gulf Coast outages already averaged 170,000 b/d during the spring. Some of the bill is scheduled: PBF has Q4 turnarounds across its Gulf, East Coast, and Mid-continent plants, and Cenovus takes Lima and the Lloyd upgrader down this autumn. The gamble is everything that is not scheduled. A fleet running at 95.8% into a second deferred cycle enters the winter heating season on fatigued metal. At $60 cracks, every shareholder wants the turnaround postponed. The metallurgy doesn't take meetings.
What we are watching
- Beijing's August batch. July's quota release is the only bearish flow of size in the product market. If it extends through August, Asian cracks stay capped and some relief leaks west. If it does not, the last buffer closes.
- Dangote's cat cracker. Every restart date since April 2025 has slipped. The first sustained run is the first real supply-side event for the gasoline crack. More slippage is upside for Fig. 2.
- The September turnaround tape. Watch whether the committed Q4 maintenance starts on schedule. Deferral announcements at $40-plus cracks would be bullish for margins now and bearish for reliability all winter.
- The pump's slow fuse. Retail diesel is $4.578 in our series while wholesale sits at $3.21, a $1.37/gal spread with pass-through still incomplete. Europe shows where that road ends: French fuel consumption fell 14% year-over-year in early May, with diesel deliveries down 9.1%. U.S. freight has not cracked yet, per DAT's easing fuel surcharges and Energy Aspects' high-frequency reads.
- The widest forecaster split in years. For the same 2026, the IEA sees demand falling 1.0 million b/d while OPEC sees it growing 1.4 million and reports record global refinery intake of 83.6 million b/d. Somebody's model is broken. The distance between them is the size of the opportunity.
