Iran War Disrupts Oil Supply, Triggers Regional Plastic Shortage in Asia

The Iran war has sent shockwaves through Asia’s petrochemical supply chains, triggering a severe shortage of plastics essential for industries ranging from healthcare to food production. As regional stockpiles dwindle, prices for polymers like polyethylene (PE) and polyethylene terephthalate (PET) have skyrocketed, driven by the blockade of oil exports through the Strait of Hormuz.

Middle East Dependency Exposed

Asia imports approximately 70% of its naphtha, a key feedstock for plastic production, from the Middle East. With supplies constrained, industries reliant on plastic packaging, medical devices, and consumer goods are grappling with escalating costs and scarcity. South Korea’s health regulators have launched investigations into suspected hoarding of syringes and other medical supplies, highlighting the crisis’s immediate impact on public health infrastructure.

'The stability of plastic as a basic industrial material has been shaken,' said Chen Ping-Kuo, a professor at Ritsumeikan Asia Pacific University. 'The disruption will move quickly through supply chains.'

Healthcare and Food Industries at Risk

The shortage of polypropylene and PVC—critical materials for syringes, IV bags, and sterile packaging—threatens healthcare systems already strained in countries like India, Indonesia, and the Philippines. In Taiwan, plastic goods have surged by up to 40%, while Malaysian dairy brand Farm Fresh has reported shortages of PET resin, essential for beverage bottles and food containers.

'When packaging becomes scarce or expensive, food spoilage increases, logistics costs rise, and prices are passed on to consumers,' noted Li Dong, a supply chain expert at Nanyang Technological University.

Shift Toward Recycled Materials

The crisis has sparked increased interest in recycled plastics and alternative packaging materials. Prices for recycled plastics have quadrupled since the war began, narrowing the cost gap with virgin plastics. This shift is reshaping investment strategies across Asia, with manufacturers of recycled materials experiencing unprecedented demand.

While the long-term impact remains uncertain, the Iran war has underscored the vulnerabilities of relying on a single geographic chokepoint for critical resources, prompting calls for diversified supply chains and 'Middle East plus one' strategies.
