Escalating tensions between the US, Israel, and Iran have disrupted shipping through the Strait of Hormuz, triggering a sharp rally in Chinese chemical futures. Methanol, plastics, polypropylene, and ethylene glycol contracts posted significant gains this week as import-dependent markets price in supply uncertainty. Overseas buyers should monitor the Strait's status closely, as prolonged disruption could tighten Asian feedstock availability and lift global chemical prices.
Supply-chain impact
The Strait of Hormuz is a critical chokepoint for energy and bulk chemical shipments from the Persian Gulf to Asia. According to China's CITIC Construction & Investment, Iran is now the world's second-largest methanol producer after China, with annual capacity of 8-9 million tonnes, accounting for roughly 12% of global trade. If shipping remains obstructed, Asian buyers face reduced import volumes and higher freight costs for methanol, urea, and other petrochemicals.
Methanol leads the rally
Methanol emerged as the strongest performer, with its main futures contract hitting the daily limit for two consecutive sessions. Shenyin & Wanguo Futures estimates that about 12 million tonnes of methanol transits the Strait of Hormuz annually en route to China. Longzhong Information notes that the Middle East is the world's dominant methanol export region, and its supply is heavily reliant on sea transport. Any sustained shipping disruption will directly impact Chinese methanol inventories and pricing.
Broader petrochemical exposure
Beyond methanol, Iran is also a major global supplier of urea, exporting approximately 4.5 million tonnes in 2024, ranking third worldwide. Dongxing Securities highlights that Iran's abundant oil and gas resources give it a structural advantage in several bulk chemicals, making its supply stability critical for global markets. Additionally, crude-linked products such as olefins and aromatics are rising in sympathy with higher oil prices, amplifying the overall upward pressure on chemical costs.
What buyers should watch
Overseas importers and distributors should track the duration of the Strait of Hormuz disruption and any diversion of Iranian chemical exports to alternative routes. China's methanol and urea buyers may face near-term price spikes and delivery delays. Companies with exposure to Asian petrochemical markets should reassess inventory buffers and consider hedging strategies. Any escalation affecting Iranian production facilities could further tighten global supply.
China sourcing context
China is the world's largest importer of methanol and a significant buyer of Iranian urea and petrochemicals. The current rally reflects both actual supply constraints and speculative positioning. While domestic Chinese methanol production can partially offset import shortfalls, the country remains dependent on seaborne Middle Eastern cargoes. Importers should watch for potential government intervention or release of strategic reserves to stabilize domestic prices.
