The London Metal Exchange (LME) benchmark index has surged to an all-time high, propelled by a sharp rally in aluminium prices as geopolitical turmoil in the Middle East disrupts global supply chains. The index, which tracks six primary base metals, has advanced nearly 12% over the past four weeks, closing at a record on Thursday.
Aluminium, which together with copper accounts for 75% of the index weighting, has risen roughly 15% since the onset of the Iran war. The conflict has triggered direct attacks on aluminium facilities, including reported strikes on smelters in Abu Dhabi and Bahrain, while the blockade of the Strait of Hormuz has further constrained raw material flows.
Supply Squeeze Hits European Buyers
These disruptions have curtailed the movement of bauxite and alumina, forcing operational adjustments across the region. Even as diplomatic signals hint at potential de-escalation, the physical damage and logistical bottlenecks suggest that output losses may persist for months. The Middle East contributes around 9% of global aluminium output, making sustained pressure on regional production a clear challenge for markets.
European and North American buyers, already navigating sanctions on certain suppliers and trade restrictions elsewhere, are now competing more intensely for available material. This has tightened inventories and pushed premiums higher, particularly for physical delivery in ports such as Rotterdam and Hamburg. Industries from automotive manufacturing in Stuttgart to construction in Madrid are feeling the pinch, as aluminium is a key input for everything from car bodies to window frames.
The situation underscores how quickly geopolitical events can reshape commodity flows. For Europe, which relies heavily on imported aluminium, the crisis highlights vulnerabilities in supply chains that have been under strain since the pandemic. A recent analysis by European Pulse noted that the continent's slow progress in metal recycling could exacerbate such dependencies, threatening energy transition goals that require vast amounts of aluminium for solar panels and electric vehicles.
JPMorgan Flags 'Black Hole' Deficit
JPMorgan Chase has warned that the aluminium market is heading into a metaphorical 'black hole' due to the scale of supply losses. In a research note released this week, the bank highlighted a dramatic escalation in disruptions that could create a severe and prolonged deficit, marking one of the most significant imbalances in recent memory relative to overall market size. The assessment has reinforced expectations of further price strength in the coming months, with traders pricing in limited near-term relief.
Copper has also contributed to the LME's record, driven by increased buying interest from Asian industries most affected by the Strait of Hormuz disruption. While movements in other metals within the index—such as zinc, lead, tin, and nickel—have been more restrained, the combined influence of aluminium and copper has been the primary driver of the benchmark's ascent.
Traders and downstream users across Europe are watching developments in the Middle East with close attention. The crisis comes as the continent grapples with broader inflationary pressures, and any sustained rise in metal prices could feed into higher costs for consumers. For now, the focus remains on whether diplomatic efforts can restore stability to the region's aluminium supply chains before the deficit deepens further.
