The International Energy Agency (IEA) reported on Wednesday that global diesel markets are expected to face supply constraints into the latter half of 2027, citing significant inventory declines and reduced exports. The assessment was released in the agency’s October Oil Market Report on October 14, 2026.
According to the IEA report, a counter-seasonal tightening in the third quarter, combined with larger-than-normal inventory drawdowns, has reduced stock levels ahead of the winter season. The agency noted that global diesel exports fell by 700,000 barrels per day year-on-year in September. This was attributed to a 1.3 million barrel per day reduction from Russia and the Middle East, which was not fully offset by supply from other producers.
The report detailed that wholesale diesel prices reached record levels in several markets, exceeding $200 per barrel in Singapore and approximately $220 per barrel in Europe and the United States in mid-September. The IEA stated that strong demand for diesel has persisted, supported in part by government measures aimed at mitigating high consumer prices.
“Even with a rapid recovery expected in refinery throughputs into year-end, gasoil supply falls short of meeting demand in 4Q26,” the IEA report stated, adding that inventory replenishment is “unlikely before [the second half of 2027].”
The market conditions coincide with a recent agreement announced by U.S. President Donald Trump for Russia to supply 300,000 metric tons of diesel to the global market. The stated goal of the deal is to counter rising fuel prices linked to supply disruptions.
The arrangement has drawn comment from European officials. Valdis Dombrovskis, European Commissioner for the Economy and Productivity, stated at the IMF meetings in Bangkok on Wednesday that the volume of diesel discussed would not have “any macroeconomic significance.” He also said that “now is not a time to ease sanctions on Russia.”
Separately, Italian Prime Minister Giorgia Meloni on Wednesday said the deal contradicts efforts to bring Russian President Vladimir Putin to negotiations with Ukraine.
In its broader outlook, the IEA forecast that total oil demand would decrease by an average of 2.6 million barrels per day in 2026 before rising by 7.7 million barrels per day in 2027. However, the agency described the oil supply recovery as “fragile,” pointing to recent events in the Middle East.
The report noted that renewed attacks in the Gulf region could affect the supply recovery. This week, Saudi officials reported that an administrative building for oil company Saudi Aramco in Riyadh was targeted during a series of attacks on the Saudi capital by Yemen’s Houthis.
