The Magnitude of the Middle East Supply Crisis

The international aluminum industry is currently navigating what experts describe as the most significant base metals supply shock of the post-2000 era. According to Nick Snowdon, head of metals and mining research at commodity trader Mercuria, the ongoing conflict involving Iran has fundamentally destabilized a region responsible for approximately 7 million metric tons of annual smelting capacity. This output represents roughly 9% of the total global supply, leaving critical sectors such as aerospace, construction, and automotive packaging facing a prolonged period of scarcity and extreme price volatility.

Market Deficits and Depleted Inventory Buffers

Mercuria’s current projections indicate that the aluminum market is bracing for a minimum deficit of 2 million tons through the remainder of 2026. This shortfall is particularly alarming when contrasted with the current global "visible" inventory, which stands at a mere 1.5 million tons. Even when including non-visible stock, the total global buffer is estimated at just over 3 million tons, providing very little insulation against further escalations. Snowdon noted that these estimates are conservative, as they rely on the optimistic assumption that alumina feedstock flows through the Strait of Hormuz will stabilize enough to allow some smelters to restart this quarter.

Regional Vulnerabilities in the US and Europe

The Western world finds itself acutely exposed to this disruption due to a heavy reliance on Middle Eastern imports and historically low domestic stockpiles. In 2025, nearly 22% of all primary and alloyed aluminum imported by the United States originated from the Middle East, while Europe sourced 18.5% of its requirements from the region. With domestic capacity in the US and Europe already running at near-maximum or having been permanently idled during the energy crisis of 2022, there is virtually no spare capacity available to compensate for the lost Gulf production.
