Crude is in surplus. Diesel is still the problem. The Trump deal changed neither.

Global oil supply rose to 105.4 million barrels a day in October, lifting supply above demand for the first time since the Middle East conflict began. That is the headline from the International Energy Agency's November Oil Market Report, released on Friday. Within it sits a second number that has travelled further than the first: Russia's crude oil production rose by 210,000 barrels a day to 8.73 million barrels a day. The diesel supply agreement between President Trump and President Putin was announced on 9 October. The crude figure is for October. The inference writes itself, which is precisely the problem.

The IEA did not directly link the increase in Russian crude production to the diesel agreement. That is not a quibble about wording. It is the distinction between a coincidence of timing and a causal claim, and the public framing of the deal has collapsed the two. A crude rebound is being banked as evidence that the agreement is working, when the agency producing the data has not made that connection and the product at the centre of the agreement is not crude at all.

Diesel is where the constraint sits. The IEA reports that 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 agreement announced on 9 October was a diesel supply agreement. The October data show crude flowing more freely and refined product exports still under pressure. If the deal was designed to relieve the tight product, the tight product has not been relieved in the figures available so far. If it was designed to move crude, nobody framed it that way at the time.

The wider balance is loosening regardless. Global supply reached 105.4 million barrels a day in October, and the IEA expects demand to decline by 2.7 million barrels a day in 2026 to 102.3 million barrels a day before rebounding by about 2 million barrels a day in 2027 to 104.3 million barrels a day. A crude surplus of that shape eases headline oil prices. It does not ease diesel, and diesel is what moves freight, farming and the cost of getting goods to a shelf. The market has split: crude loosening, refined products still tight. A deal sold as a supply fix has to be judged against the half of the market that is still constrained, not the half that is recovering for reasons the IEA has not attributed to it.

The strongest case for the agreement is timing, and it deserves a fair hearing. The deal was announced on 9 October. The IEA's production figure covers October as a whole, and a month is a short window in which to detect the effects of a supply arrangement, particularly one involving shipping, refining and port logistics rather than a single tap. Crude that was already loading when the agreement was announced would appear in October's numbers without the deal having caused it; diesel that the agreement might eventually release could take longer still to show up in export data. On this reading, the absence of a visible diesel effect is not evidence of failure. It is evidence that the calendar has not yet allowed the question to be answered.

That argument is reasonable, and it cuts both ways. If a month is too short to detect the deal's effects, then a month is also too short to claim them. The crude rebound cannot be too early to attribute to the agreement when it suits the framing and too early to assess when it does not. The honest position is that the October figures do not yet tell us whether the agreement is working, in either direction. What they do tell us is that the constraint the agreement was meant to address remains in place, and that the crude recovery being credited to it has no established link to it in the agency's own reporting.

There is a further question the data cannot settle: how much of Russia's crude rebound reflects the broader recovery in Gulf exports rather than anything agreed in October. The IEA's report describes a market returning to surplus as Gulf exports recover. Russia's 210,000 barrel a day increase sits inside a 2.3 million barrel a day month-on-month rise in global supply. Isolating one producer's contribution from that tide requires attribution the IEA has not offered. Officials have not said how they apportion the increase, and until they do, the crude number is a data point in search of a cause.

None of this requires impugning anyone's honesty. It requires reading the report that is being cited. The diesel agreement may yet prove its worth; the IEA's next monthly report, covering November, will be the first that can begin to show whether product exports respond. Until then, the claim that the deal has fixed supply runs ahead of the evidence, and the evidence that matters most — diesel — has not moved.
