Retail diesel falls 9 cents to $4.578 as UAE floods crude and Russia's biggest refinery goes offline

The EIA weekly retail diesel average dropped 9 cents to $4.578 a gallon, effective Monday, its 12th decline in 13 weeks. It matters to anyone hauling freight because this is the number most fuel surcharges ride on. Your customers just got a small break, again.

The oil market underneath that price is split about as wide as it gets. FreightWaves flagged the same bifurcation the trade has been staring at for weeks. AAA had street diesel at $4.765 on Tuesday, up a shade under a penny from the day before, while the DOE benchmark fell. When three separate reads on the same product disagree by nearly 20 cents, buyers should treat any single quote with some caution and watch the trend instead of the tick.

UAE barrels

The UAE pumped above 3.8 million barrels a day in June, near a record, after quitting OPEC to get out from under production caps. Bloomberg data put exports even higher, at 3.94 million bpd. More crude on the water tends to pull benchmarks lower, and that is part of why the diesel slide has legs. For a jobber, extra Gulf supply reads as continued downward pressure on your cost of goods, at least while it lasts.

Omsk offline

A Ukrainian drone strike halted Russia's largest refinery, at Omsk, according to Reuters and several outlets. Russian crude and products are not landing in US racks, so the direct effect is small. The indirect one is not: a big refinery offline pulls diesel and gasoline off the global board, which can firm product cracks even as crude eases. That leaves more crude but less refining running at the same time.

Hormuz easing

Saudi Arabia is weighing an expansion of its East-West pipeline by as much as 2 million bpd to route more Gulf crude around the Strait of Hormuz, per Reuters. Traffic through the strait is also recovering. Two VLCCs carrying 4 million barrels of Saudi crude are moving again, and Indian state refiners are back chartering Iraqi cargoes that transit Hormuz, with Iranian barrels back in play if Washington extends its waiver past August 21. A calmer chokepoint takes a fear premium out of crude.

What to watch

Whether the DOE benchmark logs a 13th drop next Tuesday, and whether the AAA and DOE reads converge or keep diverging. Watch how long the Omsk outage runs, because a prolonged repair could firm diesel cracks even with crude soft. And watch the August 21 waiver deadline, which could add or subtract Iranian barrels from an already well-supplied market.
