IEA Flips Q4 Oil Outlook to 1.7 Million Bpd Surplus as Gulf Flows Recover

The world oil market will flip into surplus in the fourth quarter, the International Energy Agency said on Friday, with supply averaging 105 million barrels per day — 1.7 million bpd above forecast demand. That reverses the agency's earlier call for a Q4 deficit, and it landed straight on prices: Brent crude gave up earlier gains after the 0900 GMT release, last trading down 0.1% at $95.71 a barrel.

The mechanism is simple. Gulf producers have rebuilt exports faster than demand has grown, even though the war in Iran has no resolution and tanker attacks in the Gulf continue. Producers are using workarounds the market now knows well — so-called dark crossings through the Strait of Hormuz, where tankers switch off tracking signals to evade attack.

"The oil market is showing tentative signs of rebalancing, with global oil supplies surpassing demand for the first time since the outbreak of the war in Iran," the Paris-based agency said in its monthly report.

How fast has supply come back?

Fast. OPEC+ — the exporter group plus allies such as Russia — pumped 41.23 million bpd of crude in October, OPEC said on Wednesday. That is up roughly 2.04 million bpd from September and equals 97% of the pre-war February volume.

Supply is also rising outside the cartel. Production from the United States, Canada, Brazil, Argentina and Guyana will climb by 1.6 million bpd this year, the IEA said. In 2027, global supply is projected to rise by 6.6 million bpd to 108.1 million bpd, led by a further recovery in Gulf output.

What does this change for shippers and refiners?

Plenty. The IEA sketched out the remaining volumes from the record release of emergency reserves its members pledged in March: 71 million barrels will be made available by the end of February, including 15 million barrels of diesel to ease market tightness. That diesel tranche matters most for freight — distillate cracks have been a cost driver across trucking and shipping all year.

Demand is doing part of the rebalancing work too. High prices have curbed consumption. The IEA now forecasts world oil demand falling by 2.7 million bpd in 2026, to 102.3 million bpd, before rebounding by 2 million bpd in 2027 — little changed from its previous forecasts.

Where the surplus goes from here

The agency sees the 2027 surplus at about 3.8 million bpd, slightly below the 3.94 million bpd it forecast last month. The 2027 supply growth estimate itself came down by 1.1 million bpd from the October report, a cut the IEA tied partly to a downward revision from Iran, whose exports remain squeezed by a US blockade.

Other forecasters read the market the same way. JPMorgan last week projected a global surplus of 1.4 million bpd for October, despite the unresolved war and ongoing tanker attacks.

The direction of travel is clear: barring a fresh escalation in the Gulf, the balance of power in oil pricing tilts back toward buyers through 2027, with freight markets watching whether the diesel tranche of the strategic release keeps distillate premiums in check.
