The sudden change in trajectory for these sanctioned vessels follows a week of direct military engagement in the Persian Gulf. U.S. Central Command reported that forces disabled an oil tanker near Kharg Island on Thursday, part of a broader campaign that has seen three commercial ships redirected and another boarded for non-compliance. This intensified naval presence is being framed by the U.S. as a "steel wall" meant to stifle Iranian maritime trade.

Energy flows through the Strait of Hormuz have effectively stalled, dropping to a two-month low as operators shun the chokepoint. With the regional threat level for shipping elevated to "severe" following recent strikes on tankers and subsequent U.S. retaliatory actions, the fragile stability established by previous diplomatic agreements has evaporated. Tanker owners are increasingly unwilling to risk the passage, leaving major energy routes through the Gulf of Oman largely paralyzed.
