Middle East conflict threatens global aluminium supply
The ongoing conflict in the Middle East is introducing new upside risks to the global aluminium market, extending the fallout beyond the existing impacts to oil and gas.Given the concentration of export-oriented smelting capacity in the Gulf and the reliance on shipping routes through the blockaded Strait of Hormuz, disruptions to regional trade flows could remove up to 3.5mt of aluminium output from the global market in 2026, according to Wood Mackenzie.Though Iran itself only produces about .6mtpa of aluminium, ING analysts say the greater market risk stems from potential disruptions to the Middle East Gulf region aluminium exports as well as alumina and bauxite imports passing through the Strait of Hormuz.Wood Mackenzie principal analyst Charvi Trivedi says the Strait of Hormuz is effectively a chokepoint for the global aluminium market.“Disruptions here could cut off up to 60% of alumina supply to Middle Eastern smelters, rapidly deepening the market deficit,” she said.“The longer the conflict persists, the more difficult it becomes for producers to sustain operations, with risks increasingly skewed toward further supply losses and higher prices.”ING analysts say aluminium smelters in the Gulf are heavily reliant on continuous imports of raw materials, such as alumina, leaving production vulnerable to shipping disruptions.In a direct response to alumina supply issues, Qatalum has reduced the operational capacity of its smelter in Qatar to 60% and Ma’aden, a Saudi Arabian producer, is supplying emergency alumina to neighbouring smelters, according to Wood Mackenzie.Direct attacks on aluminium sites have also forced producers into emergency responses across the region. On March 28, Iran struck major industrial infrastructure at two major aluminium production facilities, the Emirates Global Aluminium’s (EGA) Al Taweelah smelter in Abu Dhabi and Aluminium Bahrain’s (Alba) smelter in Bahrain.Following the attacks, EGA entered emergency shutdown at its 1.6mtpa facility and Alba expects to operate at an estimated utilisation of about 30% until damages are repaired, according to Wood MacKenzie.With the majority of Middle Eastern aluminium production exported to key markets —about 80 – 85% according to Wood Mackenzie — including Europe, the US, Japan, South Korea, Turkey and Mexico, the disruption poses significant risks to global manufacturing supply chains.Wood Mackenzie principal analyst Uday Patel says the disruption highlights how concentrated and fragile aluminium supply chains have become.“With so much production and export infrastructure tied to a single trade route, even short-term disruptions can have outsized and immediate global consequences,” he said.Prior to the escalation of the Middle East conflict, ING said the aluminium market was already under major pressure from China’s 45mt production cap, trade dislocation and the imminent shutdowns of South 32’s (ASX: S32) Mozal aluminium smelter in Mozambique.Wood Mackenzie expects aluminium prices to rise to about $5000/t in 2026, with outcomes highly sensitive to the duration and severity of the conflict. ING analysts predict that, in a sever disruption scenario, aluminium prices could briefly move above $4,000/t, but demand destruction would likely limit further upside.
