Dozens of commercial vessels have anchored outside Iran’s main ports in recent days as tensions with the United States continue to escalate, according to maritime tracking data and industry sources.
The ships, including oil tankers, cargo, and bulk carriers, are reportedly staying clear of port limits to reduce the risk of damage if military strikes target nearby infrastructure. Data from maritime intelligence provider Pole Star Global shows the number of tankers within Iran’s exclusive economic zone (EEZ) along the Gulf and Caspian coasts jumped from just one on January 6 to 36 by January 12.
MarineTraffic analytics indicate that 25 bulk carriers remain stationary near Bandar Imam Khomeini, while another 25 container and cargo vessels are anchored off Bandar Abbas further south. These ports are key hubs for Iran’s imports and oil exports.
The precautionary measures come as the United States pulls some personnel from Middle Eastern bases after Iran warned neighboring countries that American military installations could be targeted if the U.S. strikes.
The U.S. Navy’s Combined Maritime Force recently reported a “substantial” increase in GPS and satellite navigation interference in the Gulf and Strait of Hormuz, which officials say is likely part of Iran’s force protection measures amid growing unrest.
Iran has also experienced unexplained blasts in its ports over the past year, including the June 2025 airstrikes in Bandar Abbas and earlier explosions in April that killed at least 70 people.
With widespread protests challenging Tehran’s government, Iranian authorities are working to maintain control while signaling a readiness to counter potential U.S. intervention. Experts warn that vessels navigating the area could face disruptions due to political tensions and heightened security measures.
