Iran has once again moved to assert full control over the Strait of Hormuz, reversing a brief reopening of the critical global oil shipping route and escalating tensions with the United States.
The Iranian Revolutionary Guard Corps Navy (IRGC) announced that the strait is effectively closed and warned that any vessel attempting to pass without approval could be targeted. The move comes less than 24 hours after the waterway was briefly reopened and commercial traffic resumed.
Iran insists the closure will remain until the United States lifts what it describes as a naval blockade on Iranian ports and vessels. Iranian authorities say the blockade violates existing ceasefire understandings linked to the broader US Israel Iran tensions.
Senior Iranian political figure, Mohammad Bagher Ghalibaf stated that Iran maintains full control of the strait and dismissed the United States actions as misguided and provocative.
At the same time, Iran’s foreign ministry had earlier indicated that the Strait of Hormuz was open for commercial shipping, a statement that briefly eased global oil market concerns and allowed several vessels to pass. However, that position was quickly reversed as security tensions increased again in the Gulf region.
Reports from maritime monitoring agencies indicate that Iranian naval forces issued warnings to multiple ships in the area, advising them to avoid passage. There were also reports of gunfire involving commercial vessels, with India confirming that two of its flagged ships were affected in a security incident.
President Donald Trump warned that Iran cannot use the strait as a form of pressure, insisted that existing naval measures would remain in place unless a diplomatic resolution is reached within the ongoing negotiation timeline.
Analysts say the situation reflects a renewed power struggle over one of the world’s most strategic oil corridors, with both sides attempting to use access to the Strait of Hormuz as leverage.
The Strait of Hormuz remains one of the most important maritime chokepoints globally, carrying a significant portion of international oil trade, making the renewed tensions a concern for global energy markets and shipping stability.
