Middle East conflict risks aluminum, plastics supply for automakers

On the Dash: 

• Rising costs for aluminum, plastics, and petrochemical-based parts may affect vehicle pricing and margins.
• Supply chain delays could extend delivery times and create inventory challenges.
• Automakers may prioritize high-margin vehicles, impacting the availability of lower-priced models

As oil shipments through the narrow waterway face potential stoppages amid threats of Iranian attacks, the International Energy Agency announced it would release 400 million barrels from reserves. But analysts say the impact extends far beyond fuel, touching metals, agriculture, autos, and consumer goods worldwide.

Aluminum, a key industrial metal, is among the most vulnerable. In 2025, the Middle East accounted for roughly 21% of U.S. imports of unwrought aluminum and 13% of wrought aluminum, both used in automotive, aerospace, and construction manufacturing. Japanese and South Korean auto suppliers are reportedly negotiating alternative sources from Russia, India, and other Asian producers, but switching suppliers could increase costs and delay deliveries.

Fertilizer shipments are also at risk, with roughly one-third of global trade moving through the strait. New Orleans urea prices have already risen from $475 to $680 per metric ton, raising concerns for Midwest corn and soybean planting and potential food inflation. Petrochemical and plastic feedstocks, critical for automotive parts and packaging, could rise 15–25% if disruptions continue, according to analysts.

Shipping delays and port congestion are expected within 2–5 weeks if vessels are rerouted, further tightening global supply chains. Major carriers Maersk and Hapag-Lloyd have suspended Middle East routes. Automakers, including Volkswagen and Lucid, are monitoring the situation, but operations remain largely unaffected for now.

Analysts caution that the longer the conflict persists, the more unpredictable shortages and cost increases could become. Dealers should prepare for rising prices, extended delivery times, and potential prioritization of high-margin vehicles as supply chains adjust.
