Vessel traffic through the Strait of Hormuz has dropped to its lowest level in weeks following intensified attacks between the U.S. and Iran [1].
This decline threatens global energy security and commercial shipping, as the narrow waterway serves as a critical link between the Persian Gulf and the Gulf of Oman. The collapse in traffic suggests that commercial operators are avoiding the region despite official assurances regarding the waterway's status.
Live vessel-traffic monitoring shows a sharp decline in ship movements after a week-long escalation of strikes between the two nations [2]. Shipping traffic collapsed within a week of these intensified attacks [3]. According to reports, traffic sank to its lowest level in five weeks [4], while other data indicates it fell to its lowest level in more than a month [5].
During the week of July 7 to July 13, 2026, the region saw a surge in military activity. Iran reportedly fired at two ships in the strait as traffic declined [4]. The U.S. has responded with its own strikes during this period of escalation [2].
Donald Trump said the Strait of Hormuz is open to all ship traffic except for Iran [6]. However, the continued drop in commercial activity contradicts the assertion that the waterway remains viable for general transit.
Iranian officials have responded to the tensions with warnings about diplomatic and economic dealings. Mohammad Bagher Ghalibaf said, "The era of 'one-sided deals' is over; those who fail to keep their word will pay the price" [6].
Commercial vessels continue to face high risks as U.S. and Iranian military forces maintain a presence in the area [2]. The volatility has left shipping companies hesitant to navigate the strait, regardless of the U.S. government's stated policy on accessibility.
“Shipping traffic collapsed within a week of intensified attacks”
The discrepancy between the U.S. administration's claim that the strait is open and the actual collapse in vessel traffic highlights a crisis of confidence among global shipping firms. When commercial operators prioritize risk avoidance over official government assurances, it typically signals a belief that the threat of collateral damage from military strikes outweighs the economic incentive to transit the route. This creates a de facto blockade that could trigger spikes in global oil prices and insurance premiums.
