IRGC Naval Harassment of Gulf Tankers Intensifies Following U.S. Strikes Near Hormuz

Full prediction
Within 24 hours, IRGC naval units are likely to step up close-approach harassment, warning shots, and boarding attempts against commercial tankers near the Strait of Hormuz in response to U.S. strikes on IRGC-linked vessels. Shipping under U.S., UK, Saudi, Emirati, and Qatari-linked ownership or flags will be most at risk, with insurers and shipmasters forced into evasive routing and higher security postures. This will raise operational friction for oil and LNG exports without yet triggering full blockades, tightening the psychological choke on Gulf energy logistics. Confirmation would come from multiple AIS-off incidents, new video of IRGC fast-boat approaches, or emergency reroutings reported by maritime trackers; a quick U.S.–Gulf public deconfliction statement and visible IRGC pullback would undercut this forecast.
