Strait of Hormuz seeing less traffic as threat from Iran increases to commercial sailors - report

What Happened

Commercial traffic through the Strait of Hormuz plummeted after Iran shifted from short-range projectiles to cruise missiles in attacks on vessels, resulting in three sailors killed and over a dozen wounded in the last week alone, per International Maritime Organization data cited by The Wall Street Journal. Only eight ships transited the strait on Thursday—half of them Iranian—compared to a daily average of 30 the week before, according to ship-tracking firm Kpler. Chris Long, head of intelligence at maritime security firm Neptune P2P, attributed the change to recent US strikes on Islamic Revolutionary Guard Corps (IRGC) coastal targets, saying it forced Iran to launch cruise missiles from deeper inland. The weapons are more expensive and rely on chemicals imported from China, security officials noted. The Indian Directorate of Maritime Administration advised Indian sailors not to deploy on ships passing through the strait after several Indian nationals were killed.

Key Actors

Why It Matters

The Strait of Hormuz is a critical choke point for global oil shipments, and the sharp reduction in traffic—down to just eight ships from an average of 30 per day—signals a severe disruption to maritime trade. Iran’s adoption of cruise missiles, which are more lethal and can be fired from inland positions, marks a significant tactical escalation that could further deter commercial shipping and raise insurance and security costs. The shift follows US military actions against IRGC coastal assets, illustrating a direct cause-and-effect cycle of escalation between Washington and Tehran that risks drawing in other regional and global actors.

Watch For

Monitor daily ship transit numbers for signs of recovery or further decline. Watch for additional naval patrols or military operations by the US or allies aimed at safeguarding commercial vessels, and for Iran’s potential expansion of targeting to other chokepoints. The Indian advisory may be followed by similar warnings from other nations if casualties rise, while diplomatic channels—including any Oman-mediated backchannel—could emerge to de-escalate.
