The International Energy Agency warned on Wednesday that global diesel supply will remain tight well into next year, saying war-related losses from Russia and the Middle East and heavy inventory drawdowns have left markets without enough stock cover ahead of the winter demand season.
In its October Oil Market Report, the IEA said supply would remain tight into the latter half of 2027. A counter-seasonal tightening in gasoil markets in the third quarter, combined with "much heavier-than-normal inventory declines" in the preceding three months, had "deprived global gasoil markets of crucial stock cover ahead of the peak winter demand season," the agency said.
Global diesel exports dropped by 700,000 barrels a day last month compared with a year earlier, according to IEA data. A 1.3 million barrels per day loss from Russia and the Middle East was "only partly offset by higher supply from other sources."
Prices have reflected the strain. Wholesale diesel exceeded $200 a barrel in Singapore in mid-September and reached all-time highs of around $220 a barrel in Europe and the United States. "Retail diesel prices have risen in tandem to record levels in most major economies," the IEA said, while noting that relatively price-inelastic diesel demand has remained strong, supported by government measures aimed at easing high prices for consumers. Broader oil demand has weakened under higher prices.
"Falling inventories, soaring cracks, and steepening levels of backwardation have signalled the need for additional supplies," the IEA said. "However, even with a rapid recovery expected in refinery throughputs into year-end, gasoil supply falls short of meeting demand in 4Q26, suggesting that the replenishment of lost inventories, outside of typical seasonal fluctuations, is unlikely before [the second half of 2027]."
U.S. diesel prices passed $6 a gallon for the first time last month as the Iran war continued to affect global energy markets, and some market watchers have warned elevated prices could linger for months. At a Shell station in Carson, California on September 22, pump prices were advertised above $6 a gallon for gas and above $8 a gallon for diesel.
Last week, U.S. President Donald Trump said he had made a deal with Russian President Vladimir Putin for Russia to immediately supply 300,000 metric tons of diesel to the global market to offset war-driven price rises. CNBC's related reporting noted the volume equals less than two weeks of U.S. demand.
The IEA also warned that tensions in the crude freight market meant delivered diesel prices in the main importing markets, Europe, Africa and Latin America, could rise again in the coming weeks.
Analysis
Why This Matters
- Diesel powers freight, farming, shipping and winter heating, so a prolonged squeeze feeds into the price of goods and household energy bills across most economies.
- The IEA expects the shortage to extend into the second half of 2027, meaning at least two peak winter demand seasons are affected.
- The political response is already visible: the reported U.S.-Russia supply deal underscores how fuel prices are driving major-power diplomacy.
Background
The International Energy Agency, the Paris-based adviser to major oil-consuming economies, publishes monthly assessments of the global supply and demand balance. Diesel and other middle distillates are refinery products, and output typically rises when wholesale prices make processing profitable. The current crunch follows war-related disruption to exports from Russia and the Middle East, two of the world's largest suppliers of refined fuels, at a time when inventories had already been drawn down. Diesel demand is generally considered less responsive to price than gasoline because businesses and households cannot easily switch fuels in the short term.
Key Perspectives
The IEA: Argues that even a rapid recovery in refinery output will not close the gap in the fourth quarter of 2026, and that rebuilding depleted stocks is unlikely before the second half of 2027. It also warns that crude freight-market tensions could push delivered prices higher again in Europe, Africa and Latin America.
Producers and refiners: Record wholesale prices, around $220 a barrel in Europe and the United States, create a strong commercial incentive to run refineries harder, which underpins the IEA's expectation of a supply recovery by year-end.
Governments: Facing record retail prices, several have taken measures to cushion consumers. The Trump administration announced a deal for Russia to supply 300,000 metric tons of diesel immediately, a volume CNBC notes equals less than two weeks of U.S. demand.
Critics and skeptics: Market watchers cited by CNBC caution that elevated prices could persist for months. Analysts such as Kpler put the global diesel deficit at around 1 million barrels a day, and skeptics may question whether a one-off Russian shipment, agreed with an adversary, can meaningfully shift that balance.
What to Watch
- Whether refinery throughput recovers as quickly as the IEA expects before the end of the year.
- Wholesale diesel price movements in Singapore, Europe and the United States, and how crude freight rates affect delivered costs in importing regions.
- Whether the reported Russian diesel shipments materialize and whether further government intervention follows.
