Dozens of commercial vessels, including oil tankers, bulk carriers, and cargo ships, have anchored outside Iranian ports in recent days as rising tensions with the United States create uncertainty in the region.

Shipping and maritime sources say the move is precautionary, keeping ships away from port limits to reduce the risk of collateral damage in case of airstrikes. Analysis from Pole Star Global shows tankers entering Iran’s exclusive economic zone (EEZ) jumped from just 1 vessel on January 6 to 36 by January 12.

Data from MarineTraffic reveals that 25 bulk carriers are currently stationary near Bandar Imam Khomeini, while another 25 container and cargo ships have anchored off Bandar Abbas further south.

The developments follow a series of regional incidents, including Israeli airstrikes on Bandar Abbas in June 2025 and unexplained blasts in April that killed at least 70 people. Tehran has also warned that it may target U.S. bases if Washington intervenes against anti-government protests.

The U.S. is reportedly withdrawing some personnel from Middle East bases, while the U.S. Navy reports increased interference with navigation systems like GPS in the Gulf and Strait of Hormuz. Officials say this is likely part of force protection measures amid the ongoing political unrest.
Iran relies heavily on maritime trade for both imports and oil exports, making the situation a significant concern for shipping operations in the Gulf region.
