Petrochemicals Sector: Strait of Hormuz Closure Creates Polyethylene Supply Shock

Executive Summary

Philip Geurts from BloombergNEF delivered stark numbers: the Strait of Hormuz closure eliminates 12% of global polyethylene production capacity—18 million tons—equivalent to Europe's entire consumption. Asian crackers in Japan and South Korea are declaring force majeure, with 30-40 facilities announcing production cuts. The supply shock extends beyond direct polymer exports to feedstock disruption, where naphtha and LPG shortages could force 15-17% cuts to Asian ethylene production. Unlike gasoline or jet fuel, polyethylene demand is non-fungible—there are no viable alternatives for food packaging at scale. Geurts emphasized that 60-70% of ethylene goes into polyethylene for packaging applications, creating inelastic demand that cannot be easily destroyed. The timing is critical: Asian inventories provide only weeks of buffer, with material shortages expected to peak in early April as existing shipments are exhausted. This crisis accelerates a structural shift already underway—many Asian facilities were economically marginal before the war due to Chinese overcapacity. The heightened perception of Strait of Hormuz risk will likely trigger permanent capacity relocations to the Western Hemisphere, particularly benefiting US ethane-based producers who enjoy both feedstock security and cost advantages. European chemical companies, despite structural decline, may see unexpected revival as supply chains prioritize proximity over efficiency. The polyethylene futures market has already surged from $925 to $1,300 per five metric tons since January, with naphtha spreads widening dramatically as refiners slow operations to avoid costly shutdowns.
