The Impact of the Iran War on Global Aluminium Supply Chains

Disruption in Aluminium Supply
The ongoing Iran war has significantly disrupted the global aluminium supply chain, exposing vulnerabilities in Western markets. The London Metal Exchange (LME) reported that aluminium prices surged to a four-year high of $3,418 per metric ton, driven by the shutdown of smelters such as Qatalum and Aluminium Bahrain, which declared force majeure. The conflict has also threatened the Strait of Hormuz, a critical passage for 20% of the world's oil and a major hub for aluminium production, accounting for 23% of non-Chinese supply.
Changing Dynamics in Aluminium Production
The supply landscape for aluminium is undergoing profound changes. Chinese production growth has slowed, with smelters operating close to their mandated capacity cap of 45 million tons. In 2025, China imported a record 2.5 million tons of primary aluminium, while exports of semi-manufactured products fell by nearly 10%, tightening supply for Western markets. The International Aluminium Institute noted that production outside China remained stagnant, exacerbated by high energy costs affecting smelter operations in the U.S. and Europe.
Broader Supply Chain Implications
The conflict has broader implications beyond aluminium. The disruption in the Strait of Hormuz has halted oil tanker movements and affected the shipment of various goods, including pharmaceuticals from India and semiconductors from Asia. Approximately 3,200 ships are currently idle in the Persian Gulf, leading to potential shortages and price increases across multiple sectors. Patrick Penfield, a supply chain expert, emphasized that the ongoing conflict is causing significant impacts within the global supply chain, with the potential for cascading effects on various industries.
Official Responses and Future Outlook
In response to the disruptions, U.S. President Donald Trump announced measures to facilitate oil and trade movement through the Strait of Hormuz, including providing political risk insurance for tankers. The U.S. Navy has also positioned destroyers in the region to escort oil tankers. However, the situation remains precarious, with the potential for further escalation and continued supply chain challenges.
Criticism and Concerns
Critics have raised concerns about the long-term sustainability of the aluminium supply chain amid rising prices and geopolitical tensions. The World Bank has identified aluminium as a critical metal for green energy technologies, yet the current volatility poses risks to its availability. Industry analysts warn that the situation is unprecedented, and while the supply chain has adapted to previous disruptions, the ongoing conflict presents unique challenges.
