Iran shuts Strait of Hormuz following brief reopening

By Fredrick Ameh

Global oil markets have been plunged back into uncertainty following Iran’s announcement of a fresh closure of the Strait of Hormuz, just hours after the critical waterway had been reopened under a fragile ceasefire arrangement.

Iran’s military stated that the strait has been placed under “strict management and control,” citing the ongoing naval blockade by the United States as the catalyst for the renewed restriction.

The passage handles nearly one-fifth of global oil and liquefied natural gas shipments, making it one of the world’s most strategic maritime chokepoints.

While maritime tracking data showed that at least eight tankers successfully transited the corridor during the brief opening, several others reportedly aborted their journeys and turned back as tensions escalated.

The situation was further aggravated by reports of a security incident near Oman, where a tanker was allegedly fired upon by vessels linked to Iran’s Revolutionary Guards.

Despite the heightened friction, Donald Trump maintained that a peace deal involving Iran and Israel remains “very close.” Diplomatic efforts led by Pakistan and Egypt are ongoing, with further talks expected in the coming days.

However, Iranian Deputy Foreign Minister Saeed Khatibzadeh insisted that Tehran would not yield to external pressure, stating that the U.S. “cannot impose its will” on the nation.

Analysts warn that while a two-week ceasefire remains technically in place, the situation is highly volatile and could lead to significant spikes in international oil prices and deepened Middle East instability.
