IEA confirms 330 million barrels released, accelerates diesel supply to ease shortages
Key Facts
The International Energy Agency confirmed in its governing board statement issued on 15 October 2026 that releases under the collective emergency action had reached about 330 million barrels. The agency said this volume had already been made available as part of its response to energy market disruptions caused by the conflict in the Middle East. Completing the action involves accelerating the release of about 100 million barrels remaining under the earlier collective operation being carried out by member countries. The acceleration plans prioritise diesel, aiming to make more than 20 million barrels available as quickly as possible, according to the agency's statement. The move addresses tightening diesel markets, which the agency's assessment linked to renewed attacks on civilian infrastructure and energy facilities in Saudi Arabia.
The agency had said in its update issued on 7 October that cumulative releases had reached about 325 million barrels of oil. That was the previous level of completed releases, before the total announced in the mid-month statement rose as the emergency response continued. The early October update said member governments still held about 1.1 billion barrels in public emergency stocks after the releases carried out. Those public stocks included more than 200 million barrels of diesel, according to the statement issued after a meeting of member governments. The collective action dates back to the decision approved on 11 March 2026, when member countries agreed to release 400 million barrels to address market disruptions linked to the conflict in the Middle East.
In his assessment of the global diesel market, Fatih Birol cited "renewed attacks on civilian and energy infrastructure in Saudi Arabia", including Riyadh International Airport. This came as global oil supply recovered during September to reach 102.3 million barrels per day, according to the October Oil Market Report. Supply rose by 2.5 million barrels per day from the previous month, an increase the agency said was led by Gulf producers during that period. Crude exports from those producers reached 13.9 million barrels per day in September, with Saudi Arabia at the forefront of countries driving export flows. Underscoring the importance of the region's sea routes, an average of 20 million barrels per day of crude oil and petroleum products passed through the Strait of Hormuz during 2025.
Observed global oil inventories at the end of September remained 509 million barrels below pre-war levels, according to the agency's monthly market report. This inventory shortfall persisted alongside the recovery in Gulf supply and exports during the month and the collective releases from emergency reserves. On consumption, the agency expects average global oil demand in 2026 to fall to 102.4 million barrels per day, according to the October report's estimates. The agency attributed pressure on demand to higher oil prices and a deteriorating economic outlook, in an assessment combining the impact of energy costs with weaker economic prospects. Despite this expected decline in oil consumption, the agency expects middle distillate supplies to remain tight into 2027, keeping pressure on refined products in its outlook.
In trading, Reuters reported in its morning coverage that oil fell on the prospect of increased Russian shipments following U.S. waivers of some sanctions imposed on Moscow. Reuters linked that prospect to U.S. President Donald Trump's decision to waive some sanctions and the resulting potential for increased Russian shipments to the market. The decline follows a documented rally in early October, when Brent crude futures closed the 1 October 2026 session at $102.31 per barrel. The contracts gained 4.37% that day, according to the historical price record published by Investing, which displays Brent closing data. Price movements during the month coincided with the IEA's continuing emergency response, combining completed releases with plans to accelerate the availability of remaining volumes and diesel.
The IEA expects global refinery throughput to fall to a seasonal low during October, according to the trajectory outlined in its monthly report. The agency put that low at 81.3 million barrels per day, at a time when middle distillate supplies remain under pressure, according to its market assessment. It then expects refinery throughput to recover to 84.6 million barrels per day by year-end, following the seasonal decline expected this month. Alongside this projected refining trajectory, member countries are proceeding with plans to accelerate diesel availability as part of the remaining volumes under the collective emergency response. The International Energy Agency is scheduled to issue its next Oil Market Report on 13 November 2026, according to its published release calendar.
