Russian refinery strikes tighten diesel supply as US crude stocks rise 4.4 million barrels
Diesel is the bigger cost risk for fuel buyers this week. Ukrainian drones keep hitting Russian refineries, and that is tightening refined-product supply worldwide. One market note this week called the $91 Brent price superficial and put the real risk in diesel, closer to $170.
The Russian product hole
Ukraine hit refineries in Ufa overnight, in Russia's Bashkortostan region. Governor Radiy Khabirov called it a small fire at one of the plants. All three Ufa refineries belong to Bashneft, a unit of Rosneft, and reports point to a strike on the AVT-6 crude distillation unit, which is the kind of hit that takes real throughput offline rather than singeing a tank.
This is not a one-off. RBN Energy laid out how declining Russian refinery runs have kept global product prices high and pushed trade flows around. Inside Russia the strain is showing: fuel stations in the Moscow area are limiting sales. When a major exporter loses refining capacity, the barrels the world was counting on show up as diesel and gasoline that never gets made, and that shortfall gets priced everywhere, including here.
Crude climbs, stocks build
US commercial crude inventories rose by 4.4 million barrels for the week ending August 14, to 428.8 million barrels, per EIA. That puts stocks right about at the five-year average for this time of year. A build that size usually leans on price.
Prices went the other way. Brent gained 1% to $91.91 and WTI rose 1.1% to $84.99, with the Strait of Hormuz standoff still unresolved. Brent was near $70 before the war started. The read here is that traders are pricing supply risk at the wellhead and the chokepoint, not domestic barrels in a tank, so a comfortable US inventory number is not capping the board.
Permian keeps pumping
One thing working the other way on crude: Permian operators keep getting more oil and gas per well by drilling longer horizontals, with super-laterals past 15,000 feet now in the mix. That is more supply from the same rig count, and it is a slow, steady offset to the noise overseas.
What to watch
The diesel crack matters more than flat crude right now. If Russian refinery outages keep stacking up, product prices could stay firm even if crude eases. Hormuz is the other one to track; a clean strait could soften Brent while diesel holds. Next week's EIA report will show whether the crude build keeps running against a rising price.
