The United States has begun restricting vessels engaged in business with Iran from transiting the Strait of Hormuz, according to multiple shipping industry sources, creating new risks for global trade through the world’s most important oil chokepoint.
The measures, first reported by the New York Times, come as Washington intensifies pressure on Tehran following stalled nuclear negotiations. Approximately 20% of global oil shipments pass through the narrow waterway separating Oman and Iran.
‘We’re seeing widespread caution among major container lines,’ said a Dubai-based shipping analyst who requested anonymity due to commercial sensitivities. ‘At least three European carriers have quietly rerouted vessels around the Cape of Good Hope this week.’
The US Fifth Fleet declined to specify enforcement mechanisms but confirmed ‘enhanced monitoring’ of vessels with Iranian ties. Maritime insurers report rising premiums for Hormuz transits, with some underwriters demanding additional guarantees for ships carrying Middle Eastern crude.
Analysts warn the situation could escalate if Iran responds with retaliatory measures. The strait was previously the site of tanker seizures and attacks during 2019 tensions.
