Global oil supply beat demand by almost 2 million barrels a day in October, the IEA said, the first surplus since the Iran war began. Diesel stays tight.

Global oil supply exceeded demand in October for the first time since the U.S.-Israeli war against Iran began, the International Energy Agency said Friday, Nov. 13, in its monthly oil market report.[1] Supplies outstripped demand by almost 2 million barrels a day as Gulf exports recovered faster than consumption.[1] “The oil market is showing tentative signs of rebalancing,” the Paris-based agency said.[2]

Supply jumped 5.3 million barrels a day since August

World oil supply reached 105.4 million barrels a day in October.[2] That was 2.3 million barrels a day more than in September.[2] The IEA called the 5.3 million-barrel-a-day rise since August “extraordinary,” given continuing attacks on energy sites and tankers.[2]

Observed global inventories rose by 52 million barrels in October, or 1.7 million barrels a day.[2] It was the first increase in stocks since June.[2] The OPEC+ group pumped 41 million barrels a day of crude in October, about 97% of its prewar volume.[1]

Russia’s crude output rose by 210,000 barrels a day to 8.73 million barrels a day.[2] The United States, Canada, Brazil, Argentina and Guyana are set to add a combined 1.6 million barrels a day this year.[2]

A fourth-quarter deficit becomes a surplus

The agency now expects supply to average 105 million barrels a day in the last three months of 2026.[1] That is 1.7 million barrels a day above forecast demand.[1] The IEA had previously expected a fourth-quarter deficit.[1] It raised its fourth-quarter supply estimate by 3.3 million barrels a day.[2]

World oil demand is expected to fall by 2.68 million barrels a day this year, to 103.2 million barrels a day.[1] The IEA expects consumption to rebound in 2027 but stay below 2025 levels.[1] It cited high prices, electrification and fuel efficiency as drags on vehicle fuel demand.[1]

IEA member countries will also speed up the release of emergency oil stocks pledged earlier this year.[1] The move adds another 71 million barrels to the market by the end of February.[1] Follow the conflict’s effect on shipping on the Iran war tracker.

Diesel stays tight

Diesel supply remains tight, with refinery capacity and refined product exports still constrained.[2] “Persistent attacks on Russian energy infrastructure continue to choke off the country’s diesel supplies to international markets, adding to losses from the Middle East,” the IEA said.[2]

In New England, regional governors this week asked Congress for $3 billion more in heating aid as oil costs climbed.

Prices remain well above prewar levels

Brent crude, the international benchmark, traded near $72 a barrel in February, before the war began.[1] It reached $126 by the end of April.[1] About a fifth of the world’s oil and gas normally passes through the Strait of Hormuz, where shipments were blocked for months.[1]

Brent fell to $89.66 this week, its lowest level since late August.[1] President Donald Trump had told reporters the war with Iran was “effectively over.”[1] Brent then settled 3.3% higher at $95.82 on Thursday after Trump posted that “We don’t need a deal with Iran.”[3] West Texas Intermediate settled at $88.74.[3] Brent traded near $95 on Friday.[1]

Jeffrey Currie, founder of Real Macro, told CNBC that high insurance and tanker rates keep longer-dated futures elevated.[3] “While it caps the prompt barrel, it does nothing to cheapen the next one,” Currie said.[3] Track the wider picture on the U.S. economy tracker and the economic warfare dashboard.

Our Take

Opinion. A crude surplus is good news, but it is not yet relief at the pump or the oil tank. Diesel and heating oil depend on refinery output and product exports, which the IEA says remain constrained. Households planning winter budgets should watch distillate prices, not just Brent headlines.
