How Strait of Hormuz closure can become tipping point for global economy

• Aluminum prices are rising as the Middle East accounts for 21% of U.S. unwrought aluminum imports, threatening higher costs for automotive, aerospace, and construction manufacturing in the U.S. and Europe.
• Fertilizer shipments are severely disrupted with one-third of global fertilizer trade transiting Hormuz; urea prices have jumped from $475 to $680 per metric ton, risking food inflation during Midwest planting season.
• Experts estimate impacts will cascade through supply chains within 2-5 weeks, affecting petrochemicals, plastics, rubber, electronics, pharmaceuticals, garment manufacturing, and retail prices, with shipping costs rising 5-20% and delivery delays of 1-10+ days.

Market Summary: Strait of Hormuz Closure Threatens Global Supply Chains

Key Developments

The de facto closure of the Strait of Hormuz due to U.S.-Iran conflict is disrupting far more than oil shipments, threatening widespread supply chain breakdown across multiple critical sectors. The IEA took unprecedented action Wednesday to release reserves as vessel traffic halts.

Critical Commodities at Risk

Aluminum: Middle East accounts for 21% of U.S. unwrought aluminum imports and 13% of wrought aluminum. Prices already rising, threatening automotive, aerospace, and construction manufacturing costs. Aluminum futures have increased 1.65% amid tightening supply concerns.

Fertilizer: One-third of global fertilizer trade transits Hormuz. New Orleans urea prices surged from $475/metric ton to $680/metric ton—problematic timing for Midwest spring planting. CF Industries stock jumped 8.03% on supply concerns.

Other Sectors: 85% of Middle East polyethylene exports, petrochemicals, plastics, rubber, electronics, batteries, pharmaceuticals, sugar, and Asian garment manufacturing face disruption.

Timeline and Impact

Supply chain experts warn effects will materialize within 2-5 weeks as diverted containers create port congestion. Initial ocean impacts appear in 10-14 days, but real pressure hits as terminal congestion and drayage demand overwhelm capacity. Many commodity inventories cover only weeks of supply.

Market Implications

Major shippers Maersk and Hapag-Lloyd have suspended operations. Shipping costs expected to rise 5-20% through surcharges. Experts warn markets are underestimating the crisis, with one analyst noting it took just five days for significant disruption. Without resolution within a week, widespread price increases across consumer goods, packaging, and manufacturing inputs are expected, threatening higher inflation and reduced economic activity.

U.S. military escorts and insurance backstops may partially mitigate disruptions.
