Crude oil and refined fuels are no longer moving as one market. A barrel of crude may be available, but it still has to be processed into diesel, gasoline, jet fuel and petrochemical feedstocks. When refineries are damaged, offline or operating below capacity—and when major suppliers restrict product exports—the shortage shifts downstream. The result is wider crack spreads, the price gap between crude and the fuels made from it.
The bottleneck is turning crude into usable fuel
Refining capacity is not fully interchangeable. A disruption at a complex refinery can reduce supplies of specific products, particularly middle distillates such as diesel and jet fuel, even if other countries still have crude inventories or unused simpler processing capacity.
The supply shock is compounded by lower global refinery runs. S&P Global Energy estimated that global runs were 7.5 million barrels per day below July 2025 levels and expected second-half 2026 runs to average 80.1 million b/d, 2.4 million b/d below its earlier outlook.12 Goldman Sachs similarly described July refinery activity as the weakest seasonal level since the pandemic, with diesel at the center of the squeeze.

Russia’s refinery system has been especially exposed to drone damage. Reuters reported in May that facilities fully or partly halted after attacks represented more than 83 million tonnes per year of capacity—around one-quarter of Russia’s refining capacity—and that Moscow had imposed a gasoline-export ban from April through July. Such disruptions reduce the volume of fuel available for domestic consumption and export even when Russia can still produce crude.
China’s export controls removed a key swing supplier
China matters because it has the world’s largest refining sector and can be an important marginal supplier of transport fuels to Asia. In March, Beijing suspended exports of diesel, gasoline and jet fuel to protect domestic supply, a step expected to worsen shortages for Asian industrial and transport buyers.8
Exports were later sharply constrained: shipments to destinations outside Hong Kong and Macau were capped at 400,000 to 500,000 tonnes in April and May, before authorities raised the July allowance to 800,000 tonnes.6 China then eased restrictions further in July and August, and Reuters reported that refiners were expected to export slightly more than 4 million tonnes of gasoline, diesel and jet fuel in September.

That easing is meaningful, but it does not automatically restore the broader refining system. China’s runs fell to 58% of capacity in June, compared with refinery operation in Asia outside China at roughly 93% to 95% of pre-war levels.5 Lower Chinese processing and earlier export restraints therefore reduced one of the few potential buffers for regional fuel markets.
Why diesel is the most exposed fuel
Diesel is central to trucking, shipping, agriculture, mining, construction, backup generation and industrial activity. Supply losses at refineries that yield large volumes of middle distillates can therefore have an outsized effect on diesel availability and margins.
Goldman Sachs has warned that refinery strikes in the Middle East and Russia have further constrained an already stretched refining system, and said diesel remains “at the epicenter” of the rally.11 The bank more than doubled its 2027 diesel-margin forecasts, reflecting its view that outages, tight inventories and limited spare processing capacity will take time to resolve.

The key point is not that crude is irrelevant. Higher crude prices can still raise fuel prices. But when the processing system is constrained, refined products can become much more expensive than the crude feedstock itself—and can stay that way until damaged plants are repaired, throughput rises or product trade flows normalize.
Japan’s naphtha problem shows how the squeeze spreads
The impact is not limited to transport fuels. Naphtha is a major petrochemical feedstock, so higher prices or uncertain availability can squeeze producers of ethylene, plastics and other chemicals.
Japanese media have used the phrase “naphtha bankruptcies” to describe anxiety over the cost and availability of oil-derived inputs. It should not be read as evidence of a formally defined wave of insolvencies. But the underlying strain is real: a June Tokyo Shoko Research survey cited by the South China Morning Post found that about 80% of more than 7,000 responding Japanese companies reported difficulty procuring oil-derived products.11
For downstream manufacturers, the risk is a double hit: higher input costs and reduced ability to pass those costs through to customers. That can pressure margins well beyond the energy sector.
Russia illustrates the crude-versus-fuels split
Refinery outages can reduce domestic crude processing before they reduce crude production. In the short term, unprocessed barrels may be redirected into storage or exports; eventually, storage, port capacity, logistics and export constraints can force production adjustments.
Reuters reported that Russia’s crude and condensate output rose by around 100,000 b/d month on month to above 9 million b/d in July, supported by firm exports and a recovery in refinery throughput. That does not negate the fuel shortage. It illustrates the distinction: substantial crude production can coexist with a weakened ability to turn that crude into refined products or sell those products abroad.
What would ease the fuel premium?
A sustained narrowing of the gap between crude and refined-fuel prices would likely require several improvements at once:
- repairs and reliable operation at damaged refineries in Russia and the Middle East;
- higher refinery throughput, including in China;
- normalization of gasoline, diesel and jet-fuel export flows; and
- rebuilding of product inventories, especially for diesel.
Until then, the market remains vulnerable to another outage or policy restriction. Ample crude alone cannot solve a shortage of diesel, jet fuel or naphtha when the global system lacks enough reliable capacity to process and deliver them.
