Why has OPEC+ lost its ability to influence oil prices during the Iran war?

OPEC+ has lost its ability to influence oil prices because the Iran war has shut the Strait of Hormuz—a key export route for top producers like Saudi Arabia, Iraq, and Kuwait—severely constraining physical supply capacity; as a result, its announced output increases since March have remained largely on paper and failed to affect markets, unlike in previous years when its policy decisions directly moved prices.

How has China's role in global oil markets changed amid the Iran war?

China's role has shifted from major importer to a de facto market balancer: since the war began, it has imported roughly 400 million fewer barrels of oil than in the same period last year due to fuel export bans, lower refining output, and rising electric transport use—making its demand decline one of the dominant themes of 2026 and a key factor offsetting the worst-ever supply disruption, a function previously associated almost exclusively with OPEC+.
