U.S. Refineries Post Longest 95%-Plus Run Since 2000 as Global Cushion Shrinks
Three months of near-maximum American refining throughput, alongside Russia's collapse in processing capacity, leaves product markets with little buffer ahead of the winter demand build.
ICE Brent crude front-month settled at $95.82 per barrel on Thursday (2026-09-03), nearly $11 above the EIA's August Short-Term Energy Outlook forecast of $85/bbl for the third quarter — a spread that reflects how consistently oil market conditions have exceeded official projections since Strait of Hormuz disruptions began reshaping global crude flows.6
American refinery utilization has held at approximately 95% for three consecutive months, the longest such sustained run since 2000, according to Kpler. European runs are simultaneously at multi-year seasonal highs. With northern hemisphere economies moving into winter fuels demand and product inventories already stretched, there is limited spare processing capacity in the system to absorb another disruption.7
Russia accounts for much of why there is no spare room elsewhere. Ukrainian drone strikes have driven Russian crude-processing rates to an average of 3.91 million barrels per day in July 2026, the lowest since March 2005, according to EA Analytics data. That is more than 1.4 million barrels per day below the year-ago average. Russia has shifted from a chronic product exporter to a net importer, now drawing on markets that previously relied on its supply.2,7
The refinery attacks continued into August. Diesel prices surged in the week of August 10 (2026-08-10), following a Ukrainian strike on a Russian refinery and a Houthi attack on a Saudi refining facility, OilPrice.com reported. Global fuel supply was already out of balance before either event.5
Kpler data show global offline refinery capacity stood at roughly 11 million barrels per day near end of July. The firm projected that would ease to around 10 million b/d in August, before rising to approximately 12 million b/d in October and then falling to about 7 million b/d by December. The October increase arrives just as northern hemisphere heating demand typically accelerates, compressing the seasonal buffer precisely when it is most needed.7
The Strait of Hormuz has been the underlying driver since early in the second quarter. EIA's second-quarter petroleum markets review, published July 15 (2026-07-15), noted that continued constraints on crude and product flows through the strait contributed to higher and more volatile prices through most of Q2 2026. The agency's August STEO, released August 11 (2026-08-11), raised its Q3 Brent forecast to $85/bbl on the back of those disruptions, but front-month prices have pushed well past that level since.3,6
U.S. producers and exporters have benefited most clearly. OGJ reporting from June (2026-06-08) noted that rising global demand for alternative supply lifted U.S. crude, diesel, jet fuel, and LPG exports while reinforcing WTI's growing role in international pricing. The current position differs structurally from the early 2000s, when American refiners last ran at comparable utilization rates without the U.S. being a significant crude exporter.1
Refining margins have moved accordingly. TotalEnergies reported its European Refining Margin Marker rose 19% quarter-to-quarter in Q2 2026 and was up nearly threefold year-to-date, helping push adjusted net income to $6 billion for the quarter, a 68% increase year-over-year. Shell ran refineries at 102% utilization in the April-to-June period, up from 99% in Q1 2026, partly due to lower-than-planned maintenance. Shell more than doubled Q2 earnings from a year earlier.4
IEA Executive Director Fatih Birol issued a rare direct warning, saying there is "no room for complacency on oil security amid the escalation in hostilities and a continued drawdown of available commercial" inventories, according to OilPrice.com. The caution reflects three concurrent pressures: Strait of Hormuz constraints limiting crude availability, Russian refinery capacity offline after repeated strikes, and U.S. utilization at a 26-year high with no domestic slack to offer.4
As of (2026-09-03), heating oil futures stood at $4.59 per gallon and U.S. diesel at $4.60. Both are priced as though the market expects further supply shocks rather than discounts them. Kpler projects offline capacity rising toward 12 million b/d in October, the seasonal peak for capacity returns, before easing in December. Any major strike on Russian or Gulf refining infrastructure in that window would hit a system running at maximum stretch, without the product inventory cushion that has historically softened similar events.7,5
