Shipping in Persian Gulf Slows Amid Rising U.S.-Iran Tensions and Military Buildup

28 January 2026 World

DUBAI, United Arab Emirates — Shipping activity in the Persian Gulf has sharply declined as tensions escalate between the United States and Iran, with maritime intelligence agencies warning of increased risks to U.S.-flagged vessels navigating the strategic waterway. The slowdown comes amid reports that the U.S. Navy’s USS Abraham Lincoln Carrier Strike Group has entered the U.S. Central Command area of responsibility, signaling a possible military buildup in the region.

Iran has issued stern warnings of an “immediate, all-out” response to any American military action, raising concerns among international maritime operators about the safety of commercial shipping lanes vital to global energy supplies. Maritime intelligence firm Ambrey Intelligence assessed that at least five U.S.-flagged vessels face heightened threats in the Persian Gulf, prompting some operators to suspend or reroute shipments.

President Donald Trump has maintained a posture of keeping military options open, underscoring an ambiguous strategic approach that leaves a broad spectrum of potential outcomes and retaliatory scenarios on the table. “At this stage, it remains ambiguous, and probably intentionally ambiguous, what the objectives and desired outcomes are of any U.S. military action,” Robert Peters, an analyst at Ambrey Intelligence, told reporters.

The USS Abraham Lincoln Carrier Strike Group’s deployment to the region was confirmed by a U.S. official, marking a significant escalation in naval presence. The carrier group’s arrival coincides with heightened rhetoric from Tehran, which has condemned U.S. sanctions and military maneuvers. The U.S. Department of Defense, which oversees the U.S. Central Command’s operations, has not publicly detailed specific plans but has emphasized readiness to respond to threats.

Commercial shipping in the Persian Gulf, a critical artery for global oil exports, is particularly vulnerable to disruptions amid this volatile environment. The Maritime Administration has issued advisories urging caution and increased vigilance for vessels operating in the region. The U.S. Customs and Border Protection is also monitoring cargo flows closely, given the potential for sanctions enforcement and security risks.

Analysts note that the ambiguity surrounding U.S. objectives complicates efforts by shipping companies to plan safe routes. The U.S. Department of State continues diplomatic efforts but has acknowledged the “heightened risk” environment. Meanwhile, the Department of Defense is reportedly conducting contingency planning for a range of scenarios, including possible military strikes.

As the situation unfolds, the international community watches closely, mindful that any escalation could have far-reaching impacts on global energy markets and maritime security. The Persian Gulf remains a flashpoint where geopolitical tensions and commercial interests collide, underscoring the fragile balance in this critical region.
