Iran’s armed forces have blocked 30 vessels from passing through the Strait of Hormuz since August 22, escalating an enforcement campaign that has turned the world’s most important oil chokepoint into something closer to a toll road with a very aggressive operator.
The blockages are part of a broader crackdown by the Islamic Revolutionary Guard Corps Navy, which has blacklisted 45 tankers for alleged non-compliance with Iranian transit rules since August 24. Vessels that once sailed through relatively freely are now required to coordinate entry with Iranian authorities, pay transit fees, and stick to approved shipping corridors.
From highway to bottleneck
The Strait of Hormuz, a narrow waterway between Iran and Oman, typically handles a massive share of the world’s seaborne oil trade. Before the current standoff, more than 100 vessels transited the strait daily.
That number has collapsed to single digits.
