The International Energy Agency published, on 14 October, the October 2026 Oil Market Report. The global gasoil/diesel market remains under pressure, and the replenishment of lost inventories, outside ordinary seasonal swings, is unlikely before the second half of 2027. This is a monthly report, not today’s pump price.

In the third quarter of 2026, the IEA writes, the market tightened counter-seasonally: prolonged disruptions to Middle East and Russian exports forced stock draws. Winter cover stayed thin. Diesel demand, less price-elastic, held up, also helped by government measures; more price-sensitive heating-oil purchases were deferred. An IEA assessment, not one country’s customs balance.

Even with a rapid rebound in refinery throughputs into year-end, gasoil supply falls short of demand in the fourth quarter, the report says. Hence the key sentence: replenishment of lost inventories, outside typical seasonal fluctuations, is unlikely before 2H27. The surplus expected in the first quarter of 2027 would lift stocks along seasonal lines, but would not offset the deficit accumulated in 2026.

Figures from the same text: global diesel exports in September, 700 thousand barrels a day below a year earlier; the combined Middle East plus Russia loss, 1.3 million barrels a day. OECD gasoil stocks, 565 million barrels in July, 5% below pre-conflict levels. North Sea Dated, a September average of $116.89 a barrel; “at the time of writing,” about $134. Prices from the 14 October report, not from 21 October.

The IEA ties continued tightness in 2027 to a recovery of product supply from the Middle East. Without that, markets may balance through further demand cuts, at an economic cost. The G7, on 2 October, called for faster releases under the IEA Collective Action, with priority on diesel. A political commitment, not a volume already pumped in October.

Until the November report, the closed fact is the 14 October OMR: gasoil/diesel tightness stretching into 2027, and off-season stock rebuild unlikely before the second half. This is not today’s price and not a law.
