IEA Sees Oil Surplus Returning as Supply Recovery Outpaces Demand

Recovering supply is changing the oil market’s balance, but the benefits for consumers remain uneven. New forecasts, the latest trading figures and producer decisions show why cheaper crude does not immediately translate into lower fuel bills.

The International Energy Agency expects the global oil market to return to surplus in the final quarter of 2026, as recovering supply overtakes demand. Its 13 November report marks a change in the balance after months of disruption associated with the war in Iran.

The agency estimates that world supply rose by 2.3 million barrels a day in October to 105.4 million. Observed inventories increased by 52 million barrels, although the composition matters: oil held at sea rose sharply while stocks on land continued falling.

The IEA also forecasts a 2.7-million-barrel-a-day decline in demand this year, followed by a two-million-barrel recovery in 2027. These are projections for the wider market, whose path remains vulnerable to disrupted shipping.

Trading prices show relief alongside volatility

According to Reuters’ Friday closing report, Brent futures settled on 13 November at $95.84 a barrel, up two cents on the day, while US West Texas Intermediate finished at $88.56, down 18 cents. The small daily moves followed much larger swings over the preceding sessions.

Reuters described both benchmarks as heading for a weekly fall of about 2.5%, following declines of 16% for Brent and 13% for WTI the previous week. Those figures describe traded futures contracts; they are not pump prices or a direct measure of the cost paid by every importer.

The distinction is useful for assessing the economic effect. A manufacturer buying fuel under a supply agreement, a refinery purchasing crude and a driver filling a tank participate at different stages of the chain. Their costs need not adjust on the same day or by the same percentage.

A lower benchmark therefore provides one piece of evidence about easing pressure. To judge the improvement in a particular business, the relevant comparison is its delivered purchase cost, including transport and contractual terms, against what it receives for its output.

The forecast depends on how oil reaches buyers

The US Energy Information Administration’s November outlook also anticipates inventories beginning to rebuild in the fourth quarter. It expects Brent to average around $100 a barrel during November and December, with shipping constraints and the risk of further disruption limiting near-term relief.

The EIA’s scenario assumes that alternative transport routes and recovering flows gradually reduce production shut-ins. It forecasts inventories building by 3.5 million barrels a day in the first half of 2027 and Brent easing to an average of $77 in the final quarter of that year.

Those estimates require a clear date label. The outlook was released on 10 November, using model inputs finalised on 5 November. It therefore does not incorporate subsequent market events specifically. Nor does a forecast for a monthly or quarterly average predict each daily price.

For planning purposes, this is a conditional recovery scenario. The path depends on physical production and transport assumptions holding sufficiently well for depleted stocks to rebuild. A disruption to either can change the timing, even if the longer-term direction of supply remains favourable.

Producer decisions follow their own timetable

Production policy provides another part of the picture. In their 1 November statement, seven OPEC+ countries said they would maintain their September 2026 required production levels for December. The participants were Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria and Oman.

The group reaffirmed its commitment to conformity with the Declaration of Cooperation and said its next meeting would take place on 29 November. That decision is an existing policy reference point; it is not a response to the IEA report issued nearly two weeks later.

A production target and the amount of oil that reaches buyers answer different questions. The former describes an agreed level, while the latter also depends on what can be produced and transported. Reading a policy statement as proof of delivered supply would miss that distinction.

This matters when comparing successive announcements. A recovery in actual flows can change the market balance even without a newly announced change in required production. Conversely, an agreement alone cannot establish that the associated barrels have reached a refinery or become available as finished fuel.

Why diesel can follow a different path

The EIA’s explanation of diesel pricing identifies four components in US retail prices: crude, refining, distribution and retail costs, and taxes. Their relative shares vary by place and over time, which helps explain why a movement in crude is only part of the final bill.

The agency also explains that supply bottlenecks can keep regional prices elevated when fuel cannot move quickly enough between markets. Heating demand adds a seasonal influence because heating oil and diesel are closely related products. Refinery outages, import availability and local inventories can therefore matter alongside the global crude balance.

For households and businesses, the next useful test is whether relief spreads through those stages. Falling crude costs would be more meaningful if accompanied by dependable deliveries, healthier inventories and lower prices for the particular fuel being purchased. The evidence so far points to a changing balance, with the pace of consumer relief still dependent on the route from production to use.
