Shipping stalls in Strait of Hormuz after Iran declares key waterway closed again
Shipping through the Strait of Hormuz has come to a standstill following Iran's announcement of its closure, a key oil transit point handling approximately 20% of the world's oil traffic. Data from maritime intelligence sources indicate that the number of vessels transiting has sharply decreased, with many ships reportedly disabling tracking systems to obscure their movements. Although there was a brief recovery in traffic due to a previous agreement between the U.S. and Iran, current observations show a troubling decline, raising concerns over the stability of oil supply routes and market implications.
