Hormuz Strait reopening delayed to Friday, keeping oil flow constrained amid Iran‑US talks
Executive summary: Iran and the United States have delayed the reopening of the Strait of Hormuz, stating it will occur only after Friday, amid ongoing negotiations. The Strait is a critical chokepoint for global oil shipments; any delay affects oil supply forecasts and market stability.
Who is involved: Iran, United States, Pakistan (as mediator), global oil markets
Likely next: The Strait is expected to reopen on Friday, pending confirmation from both sides, which could alleviate oil supply concerns.
The Iranian authorities announced that the Strait of Hormuz will remain closed until after Friday, despite earlier reports of an imminent reopening.
