IEA says oil market flips to surplus for first time since Iran war
The International Energy Agency said in its November Oil Market Report, published Friday, that global oil supplies have surpassed demand for the first time since the outbreak of the war in Iran. The market is now set for an overhang of roughly 2 million barrels a day this quarter, versus a deficit of similar size projected a month ago, with a more substantial build in 2027.

The News
The International Energy Agency said in its November Oil Market Report, published Friday, November 13, that global oil supplies have surpassed demand for the first time since the outbreak of the war in Iran. The market is now set for an overhang of roughly 2 million barrels a day this quarter — more oil produced than the world uses — versus a deficit of similar size projected just a month ago, with a more substantial build expected in 2027.
The swing comes from a fast recovery in supply. Global oil supply surged 2.3 million barrels a day in October to 105.4 million barrels a day, up 5.3 million barrels a day since August, as Gulf exports recovered to 74% of pre-war levels — crude shipments at 82% of pre-war volumes — despite continued tanker attacks. Observed global inventories rose 52 million barrels in October, or 1.7 million barrels a day, the first increase since June.
The IEA raised its fourth-quarter 2026 supply estimate by 3.3 million barrels a day and now expects the 2026 average deficit to be 685,000 barrels a day, down from the 1.7 million barrels a day it forecast previously. It projects 2027 supply will recover 6.6 million barrels a day to 108.1 million barrels a day, while global demand is now expected to fall 2.68 million barrels a day this year to 102.3 million barrels a day, a slightly steeper decline than last month's forecast, with a 2 million barrel a day rebound in 2027. IEA members will also speed up the release of remaining emergency stockpiles, discharging a further 71 million barrels through the end of February.
A month ago the IEA expected a shortage. Now it expects a glut.
Why It Matters
An overhang is simple to picture: imagine a shop that stocks 2 million more barrels of oil a day than its customers buy. The extra has to go somewhere — into storage tanks — and when storage fills, sellers cut prices to move it. That is why a surplus is bearish for oil prices, even on a day when war fears pushed Brent up 3.3%. The IEA is saying the physical market has flipped: a month ago it expected a shortage this quarter; now it expects a glut.
The speed of the supply recovery is the surprise. Gulf exports are already back to 74% of pre-war levels, and crude shipments to 82%, even though tankers are still being attacked. In other words, the war disrupted flows far less than feared, and production has come back faster than the market assumed. Inventories rising 52 million barrels in October — the first increase since June — is the proof in the tanks: more oil is being stored because more is being produced than consumed.
The price evidence lines up with the IEA's numbers. North Sea Dated crude, a benchmark price for North Sea oil, has fallen more than 30% from $136 a barrel on October 8 to around $93 — though that is still $22 above pre-war levels, so the war premium has shrunk rather than vanished. Brent settled Thursday at $95.82, up 3.3% on the Houthi claims, per Reuters. The two stories can both be true: war fears can lift prices for a day while a growing surplus pulls them down over weeks.
For Exxon and Chevron, a surplus is a headwind, not a disaster. Both earn less per barrel when crude falls, but both are built to keep paying dividends through price swings, and both have refining and chemical businesses that can benefit when crude is cheaper. The risk is duration: if the IEA is right that the build gets more substantial in 2027, the majors face a longer stretch of lower prices, and the 71 million barrels of emergency stock the IEA members are about to release adds more supply on top.
Analyst's Take
Our call is Bearish. The IEA has moved from forecasting a deficit of about 2 million barrels a day to an overhang of roughly the same size in the space of a month, supply is already back to 105.4 million barrels a day, and inventories are building for the first time since June. Thursday's 3.3% jump was a war-fear rally; the surplus is the slow gravity pulling prices the other way.
What to watch: whether Gulf exports keep climbing toward pre-war levels, whether the 71-million-barrel emergency release lands as scheduled through February, and whether OPEC+ — which meets November 29 — answers the surplus by cutting output or lets prices fall. If demand's expected 2 million barrel a day rebound in 2027 arrives early, the surplus shrinks; if it does not, Brent's $95.82 is a high-water mark.

By The Numbers
FAQ
What is an oil overhang?
It means the world is producing more oil than it uses — roughly 2 million barrels a day more this quarter, according to the IEA. The extra oil goes into storage, and when storage fills up, prices tend to fall.
How did the market flip from deficit to surplus so fast?
Supply recovered much faster than expected: global output rose 2.3 million barrels a day in October to 105.4 million, and Gulf exports are already back to 74% of pre-war levels despite continued tanker attacks.
What is the IEA?
The International Energy Agency is a Paris-based body that advises governments on energy. Its monthly Oil Market Report is one of the most closely watched forecasts of global oil supply and demand.
Why did oil rise on Thursday if there is a surplus?
Thursday's 3.3% jump — Brent settled at $95.82, up $3.06 — was driven by war fears: Houthi claims of attacks on Saudi energy sites, per Reuters. It was not driven by supply and demand. A surplus pulls prices down over weeks; a war scare can lift them for a day.
What happens to the emergency stockpiles?
IEA member countries will speed up the release of their remaining emergency oil stockpiles, discharging a further 71 million barrels through the end of February, which adds more supply to the market.
