A year ago, Siemens Energy mapped a land route to Dammam as a backup. The Hormuz closure turned that map into the region's trade playbook overnight.
The Strait of Hormuz closure has pushed years of contingency planning into real-time execution. Supply chains that once moved through the water are now locked onto the road networks of the Arabian Peninsula.
Siemens Energy is moving turbine components and power-generation equipment to Dammam via land after the sea route was shut, according to people familiar with the logistics. Retailer Spinneys is trucking food supplies across the desert to keep shelves stocked. DP World, the ports operator, is running its inland container depots at capacity, the people said.
A year ago, a conflict between the US and Iran forced these companies to sketch out alternative routes. Back then, the plans sat on shelves. They are now live. The shift locks a critical volume of regional trade onto a road infrastructure built for local commerce. The capacity test is the real uncertainty for logistics analysts.
Cost is the immediate friction point. Moving a container from Jebel Ali to Dammam by road costs roughly three times the previous sea rate, logistics brokers said. That margin squeeze hits companies that rely on just-in-time delivery or perishable goods. It benefits logistics firms with integrated land assets. DP World owns both the Jebel Ali terminal and the Dubai Maritime City logistics zone.
The single main highway between Saudi Arabia and the UAE at Al Batha has a finite truck processing capacity. A sustained closure tightens that bottleneck. Logistics firms said they are already shifting to multi-leg routes passing through Oman to distribute the load.
The land-route thesis holds if freight tonnage through the Saudi ports of Dammam and Jeddah stabilizes at current levels. It weakens if shipping lines report sustained backlogs at overland chokepoints. The read-through for stock market analysis is straightforward: companies listed in New York or London with stated Middle East exposure now face a higher cost of goods sold.
Siemens Energy declined to comment on the specific volume of goods or the cost impact. The company's CEO is expected to address the supply chain shift at its annual investor day next month.
