The Strait of Hormuz has recently witnessed a limited number of vessels secretly traversing its waters, as observed crossings have nearly halted amid escalating military tensions between the United States and Iran. Preliminary data, analyzed by Bloomberg from Kpler information, reveals all six cargo tankers crossing the strait last Sunday did so after disabling their transponders. These clandestine operations, known as "dark crossings," have now exceeded observed passages over the preceding three days.
