Rising Maritime Tensions: Ships Anchor Outside Iranian Ports Amid U.S. Threats

In recent days, dozens of commercial vessels have anchored outside Iranian ports as tensions between Iran and the United States escalate. Shipping data indicates that this precautionary measure is a response to ongoing protests in Iran and heightened fears of potential U.S. military action. The U.S. is reportedly withdrawing some personnel from its bases in the Middle East following warnings from Iranian officials that Tehran would retaliate against American bases if attacked.

The reliance of Iran on maritime trade for imports and oil exports is significant. Between January 6 and January 12, the number of tankers entering Iran's exclusive economic zone (EEZ) surged from one to 36, as reported by maritime intelligence provider Pole Star Global. At least 25 bulk carriers were noted to be stationary in the EEZ near the major port of Bandar Imam Khomeini, while another 25 vessels, including container and cargo ships, anchored off Bandar Abbas. These movements reflect the shipping industry's cautious approach amid fears of collateral damage from potential airstrikes.

The current situation is compounded by a history of military confrontations in the region. In June 2025, Israel conducted airstrikes on targets in Bandar Abbas, resulting in significant casualties from unexplained explosions earlier that year. This backdrop of military activity contributes to the heightened alert among shipping companies operating in the area.

U.S. officials have indicated that the withdrawal of personnel is a precautionary measure amid rising tensions. The U.S. Navy's Combined Maritime Forces noted an increase in interference with Global Navigation Satellite Systems (GNSS), including GPS, in the Gulf and Strait of Hormuz, attributing this to force protection measures related to the ongoing political unrest in Iran.

Critics of U.S. policy argue that the military presence and threats of intervention exacerbate tensions rather than alleviate them. Iranian officials have expressed that such actions could provoke further instability in the region, complicating efforts to manage domestic unrest.

While the increase in shipping activity is well-documented, there are discrepancies regarding the exact nature and extent of U.S. military preparations. Some sources suggest imminent military action, while others indicate a more measured response. The situation remains fluid, with ongoing developments likely to influence maritime operations in the region.
