With the Strait of Hormuz currently classified as a zone of military operations and trust in shipping dwindling, supply chain experts are assessing the consequences for US cities if the interruption persists for two months or longer. The six US cities deemed most vulnerable to a prolonged closure of the Strait are Houston, Los Angeles, New York City, Chicago, Atlanta, and Seattle. These locations are significant for their refinery operations, port activities, or as central distribution points reliant on goods that either pass through the Strait or are influenced by oil pricing from the Persian Gulf. Houston is likely to experience immediate disruptions in refinery inputs, while Los Angeles and Seattle, as West Coast ports, may see rising shipping costs. New York, Chicago, and Atlanta serve as crucial hubs for petroleum products, industrial chemicals, and consumer items that are priced based on global oil trends. Economists caution that a closure lasting 60 days would invoke rationing measures reminiscent of the oil crisis in the 1970s.
