Iran has reversed its brief decision to reopen the Strait of Hormuz, reimposing restrictions on the critical maritime route amid an intensifying standoff with the United States.
Iran’s joint military command announced that the strait is now back under strict control of its armed forces, warning that transit will remain restricted as long as the U.S. blockade on Iranian-linked shipping continues.
The move came shortly after U.S. President Donald Trump stated that Washington would maintain its blockade of Iranian ports, even after Tehran had announced the reopening of the strait. The U.S. position ties any de-escalation to a broader agreement with Iran, including over its nuclear program.
The renewed restrictions mark a significant escalation around one of the world’s most vital energy chokepoints, through which nearly one-fifth of global oil supply passes.
Market concerns have quickly resurfaced, with analysts warning that any sustained disruption could tighten global supply and push oil prices higher, especially after earlier optimism that a diplomatic breakthrough was within reach.
Iran has long considered control over the Strait of Hormuz a key strategic tool, and its latest decision underscores its readiness to use that leverage in response to economic and military pressure.
Shipping data indicates that vessel movement through the strait remains limited, with transit reportedly confined to routes requiring Iranian authorization.
Meanwhile, United States Central Command confirmed that several vessels have been turned back since the blockade began, highlighting the scale of enforcement measures currently in place.
The escalation comes despite ongoing mediation efforts led by Pakistan, which is seeking to broker a deal between Washington and Tehran ahead of a proposed ceasefire deadline.
While diplomatic channels remain open, Iran’s decision suggests that access to the Strait of Hormuz will remain closely tied to the outcome of broader geopolitical negotiations, keeping global energy markets on edge.
