In short

What the reporting says
Global oil demand is expected to fall by 2.6 million barrels per day in 2026, with diesel accounting for 25% of the decline, according to the publisher-supplied summary. The report links the weaker demand outlook to the Iran war and says oil supply may rise temporarily before dropping later in 2026, while refinery margins remain pressured by higher crude costs. The immediate implication is a softer demand outlook and tighter margins, but the source does not give a final market price forecast.
