Prices spiked sharply, with aluminium rising as much as 2.9% to $3,231.50 per ton on the London Metal Exchange after coordinated US‑Israeli strikes on Iran prompted retaliatory attacks across the Gulf region.

Li Xuezhi, head of research at Chaos Ternary Futures: “Potential disruptions to the bauxite and alumina supplies feeding regional smelters present a very significant risk.”
BNP Paribas strategist David Wilson: “The impact on the aluminium market of sustained disruption to shipments from the region will be significant for both prices and physical premiums, particularly in Europe.”
ING strategist Ewa Manthey: “Escalation... primarily increases upside risks to physical aluminium premiums, rather than materially tightening global supply. At the centre of market anxiety lies the Strait of Hormuz, the narrow maritime chokepoint off Iran’s coast through which much of the region’s aluminium exports and raw materials flow. Reporting highlights that Middle Eastern producers account for roughly 9% of global aluminium production, a figure reinforced by consultancy AZ China. The region’s smelters, spanning Saudi Arabia, the UAE and Bahrain, depend heavily on uninterrupted passage to import bauxite and alumina, making them particularly exposed to even short‑term disruptions. Li Xuezhi, head of research at Chaos Ternary Futures, underscores the fragility of this supply model: “Potential disruptions to the bauxite and alumina supplies feeding regional smelters present a very significant risk.”

What a prolonged blockage could look like

In a more drawn‑out conflict scenario, analysts warn that aluminium supply chains could face cascading failures. Fastmarkets analysis notes that although smelters may attempt to stockpile metal at secure nearby ports, any sustained interruption to alumina replenishment would become critical. If inventories run down, smelters could be forced into production cuts, particularly as alternative alumina buyers prove limited. In such a scenario, alumina markets themselves could invert: while aluminium supply would tighten sharply, surplus alumina stranded outside the Gulf could push global alumina prices below $300 p/t, exacerbating volatility across the value chain. Citi analysts added that the conflict is generating a complex “two‑way macro pull”: “Gulf supply threats are pushing up regional premiums in Europe and the US, while risk‑off sentiment and a stronger dollar act as counterweights.” This tension is already reflected in trading patterns. LME spot contracts have moved into backwardation, signalling surging near‑term demand relative to supply. Major producers have begun to react as well: Rio Tinto has suspended negotiations with Japanese buyers and withdrew a previously offered premium of $250 per ton amid deepening supply uncertainty.

Operational impacts are already visible

Even before a formal closure of the Strait, physical infrastructure had come under strain. The UAE confirmed that debris from an aerial interception caused a fire at a berth in Dubai’s Jebel Ali port, located just kilometres from Emirates Global Aluminum’s key facilities. While not crippling, the incident illustrated how rapidly escalating conflict proximity increases operational risk for the region’s smelting hubs. Iran’s own aluminium industry, roughly 790,000 tons of annual smelting capacity, has already begun feeling the effects. AZ China estimates that between 50,000 and 80,000 tons of Iranian production have been idled as a precaution.

Who pays the price?

Europe and the United States stand to shoulder much of the fallout. Both are heavily reliant on the Gulf for aluminium imports. BNP Paribas strategist David Wilson cautions: “The impact on the aluminium market of sustained disruption to shipments from the region will be significant for both prices and physical premiums, particularly in Europe.” European premiums had already climbed to $378 per ton even before the latest escalation. In the US, structural tariffs have kept premiums elevated at $1.04 per pound, leaving buyers acutely sensitive to any Gulf‑related disruptions. ING strategist Ewa Manthey added further nuance, noting that the Middle East’s 8% share of global aluminium capacity puts the emphasis less on global shortages and more on sharp surges in regional physical premiums, especially in Europe and the U.S.  

While aluminium’s surge stole headlines, other commodities signalled broader nervousness: copper gained 0.3%, zinc rose 0.9%, iron ore edged up to $99, while the U.S. dollar strengthened, further pressuring dollar‑denominated metals. With conflict still unfolding, traders are bracing for more volatility. Billions of dollars in options trades reflect expectations that aluminium could soon breach the $3,300–$3,500 per ton range. If the Strait of Hormuz sees even partial shutdowns or prolonged risk‑driven rerouting, aluminium markets may face their most severe supply shock in over a decade.
