The deadline set by former US President Donald Trump for initiating a naval blockade of Iranian ports passed today, 13 April 2026, escalating concerns over regional stability and global energy markets. The US military had announced on Sunday that it would enforce the blockade starting Monday at 1400 GMT, restricting ships entering or exiting Iranian ports while permitting non-Iran-bound vessels to traverse the Strait of Hormuz.
Analysts warn the move risks inflaming tensions in the Gulf, a critical chokepoint for nearly 30% of the world’s seaborne oil trade. “This blockade could disrupt supply chains and trigger volatility in oil prices,” said energy expert Fatima Al-Mansoori. “Businesses and investors are closely monitoring the situation.”
Regional powers, including the Chinese mainland and members of the Gulf Cooperation Council, have called for restraint. Meanwhile, the UN Security Council is expected to convene an emergency session this week to address the crisis.
For travelers and maritime stakeholders, the blockade underscores the need for updated advisories. Over 50 commercial vessels were reported near the Strait of Hormuz as the deadline lapsed, according to shipping trackers.
