IEA Warns Global Diesel Shortage Will Extend Well Into 2027 as War Disruptions Strip 1.3 Million Barrels Per Day From Exports

The International Energy Agency warned on October 14 that global diesel supplies will remain severely constrained well into 2027, with conflicts in the Middle East and Ukraine having wiped out a combined 1.3 million barrels per day of Middle Eastern and Russian diesel exports in September alone. Diesel refining margins have hit a record $95 per barrel, and OECD government oil stockpiles have fallen to their lowest level since at least December 1989. The IEA cautioned that recovering refinery runs will not replenish depleted inventories quickly enough to ease the crunch, and warned European diesel prices in particular face further increases.

An IEA emergency reserve release agreement reached in March has so far seen members release 331 million barrels of oil through the end of September, but roughly 96 million barrels remain to be released, with 46 million barrels still owed from Europe, 40 million from the Americas, and 10 million from Asia-Pacific. Despite that planned release, the agency said shrinking inventories are likely to fuel continued price volatility.

Russia has partially offset the supply crunch by restarting diesel exports following temporary US sanctions relief, with Deputy Prime Minister Alexander Novak saying shipments can return to 3 to 3.5 million tons per month by year-end, destined for both global markets and directly to the United States. Analysts flagged that additional Russian barrels would help cap diesel prices without crushing them, keeping refining margins elevated and benefiting US refiners Valero and Marathon Petroleum.

The broader energy crisis is registering sharply in US inflation data. Fuel oil surged 15.3% in September and gasoline jumped 9.1%, together accounting for more than half of the monthly CPI increase and pushing annual inflation to 3.7%. Fuel oil is up 74.2% over the past year. US crude oil, which began 2026 below $60 a barrel, is now trading near $95. American drivers have now seen average gas prices above $4 per gallon for a record 158 days in 2026.

Geopolitical risks continue to intensify. Iran has deployed new tactics to target ships transiting the Strait of Hormuz, according to senior Iranian officials cited by Reuters, and Yemeni forces have warned they will continue strikes on Saudi airports and oil facilities, with an explosion reported in Riyadh following a missile attack. Soaring oil freight costs have separately emerged as an additional risk to fuel supply chains. India's natural gas demand has fallen by 1.5 million tons this year as the Iran war choked LNG flows from Qatar and the UAE, while Indonesian motorists are facing fuel shortages and long lines at gas stations.
