Russian Crude Processing Falls to 24-Year Low After Ukraine Hits Tankers and Pipelines
Russian refinery throughput crashed to 3.6 million barrels per day in July, threatening the fuel oil supplies Saudi Arabia has imported to offset Hormuz production losses.
Russian crude processing fell to an estimated 3.6 million barrels per day in July, the lowest monthly level since May 2002, after Ukraine expanded its drone campaign from refineries to tankers, pipelines and export infrastructure, The Moscow Times reported on Monday (2026-08-03), citing Bloomberg. Russian refineries typically processed 5.3 million to 5.6 million barrels per day during the equivalent period between 2020 and 2025 — a gap that left July throughput roughly one-third below the seasonal norm.4
Oil product consumption fell by 8% in the period, with diesel especially affected, down by close to 6%. Drone strikes have spread from fixed refinery sites to tankers and export pipelines, broadening the scope of damage to Russia's downstream sector.4
Saudi Arabia's exposure to this disruption is direct. Since the Iran war triggered Hormuz disruptions in early 2026, Riyadh has relied on Russian fuel oil to compensate for reduced domestic production caused by shut-ins across the Middle East. Saudi imports of Russian fuel oil jumped 18% in March 2026 from February after the Hormuz crisis forced those shut-ins, Reuters reported, citing LSEG data.1
The kingdom also rerouted its export logistics. Within weeks of the Hormuz closure, Saudi Arabia raised East-West pipeline flows from around 2 million barrels per day to 7 million barrels per day, preserving export volumes via the Red Sea. Russian fuel oil served as a domestic fix, keeping power generation running as temperatures climbed and Gulf gas production fell.1
But that supply has become less reliable. Russia's vessel shipments of fuel oil and vacuum gasoil fell some 6% in May from April, Reuters reported on Monday (2026-06-22), citing LSEG shipment data and traders, pulling total exports to around 3.2 million metric tons. Saudi Arabia remained the single largest buyer, accounting for more than a third of all Russian fuel oil shipments, yet Saudi imports dropped 17% month-on-month to 1.23 million metric tons in May.1
Crude prices have not reflected the severity of Russia's downstream losses. ICE Brent crude front-month traded at $84.43 per barrel on Tuesday (2026-08-04), off 2.06%, while NYMEX WTI front-month fell nearly 3% to $79.50. Hormuz shipping has partially recovered since the worst of the crisis, and the UAE raised crude output to near-record highs above 3.8 million barrels per day in June after leaving OPEC's production-cap framework, two people familiar with production data told Reuters.4,2
Refined product markets have tracked crude lower rather than signalling independent tightness. NYMEX RBOB Gasoline front-month fell 2.69% to $2.89 per gallon on Tuesday (2026-08-04), and NYMEX Heating Oil front-month slipped 1.29% to $3.83 per gallon. Analysts have cautioned that lower crude prices do not automatically produce cheaper refined products when refinery capacity has been reduced on the supply side, as is now the case in Russia.3
The immediate risk for Riyadh is whether Russian fuel oil volumes can recover even as Ukraine presses deeper into transport and pipeline infrastructure. Abu Dhabi National Oil Company has been selling crude through tenders at discounted prices, traders told Reuters, offering one alternative supply avenue. Crude is not a direct substitute for fuel oil in power generation, leaving Saudi Arabia's options limited. If Ukrainian drones continue tightening their grip on Russian tanker routes through the autumn, the 17% monthly decline Saudi Arabia absorbed in May may prove to be the easy part.2
