Iran knocks out persian gulf aluminum plants, prices sprint toward record highs
Drone and missile raids on Emirates Global Aluminium and Aluminium Bahrain on Saturday just shaved 3.2 million tonnes off global supply. London Metal Exchange futures answered Monday with a 6% moon-shot, the fastest one-day move since the 2022 energy shock. Spot premia in Europe are already 63% above February levels. The message is blunt: the world’s safety buffer for the metal that moves airplanes, AI racks and soda cans is now thinner than the foil it sells.
Why a 9% slice of output feels like a total outage
Stockpiles tracked by the LME have collapsed to a two-decade trough. Smelters from British Columbia to Brazil are already throttling back on sky-high power bills. Qatar’s Qatalum has cut 40% of output; Alba idled 19% before the first rocket hit. Add the Strait of Hormuz chokepoint—through which 90% of Gulf metal must sail—and the region’s 9% share of world aluminum suddenly dictates global price discovery. Goldman Sachs now models a 900,000-tonne second-quarter deficit, enough to cover only 45 days of consumption.
Rolling a potline back to life is not like restarting a server. Once the molten bath cools, relining cells can take six months and cost half a billion dollars. Rob Van Gils, CEO of Austria’s Hammerer Aluminium, says his firm is already rationing spot offers for Q3 because “no one can price what we cannot yet see.”
Defence budgets will feel the squeeze too
High-purity aluminum used in U.S. armor plate and aerial drones is 30% sourced from Alba and EGA. The Defense Logistics Agency declined to comment on current stock levels, but Pentagon contractors tell Coastal Code that contingency orders for 2025 delivery are being triple-locked. Rio Tinto just set a decade-high premium of $350 over LME cash for Japanese buyers—an omen of what Washington and Brussels will pay next.
Backwardation is screaming the same story: spot aluminum closed Monday at a $47-per-tonne premium to three-month futures, after touching $61 on Friday, the widest since 2007. Traders call it a cash-market jailbreak; manufacturers call it a production tax.
The record to beat is $4,073 a tonne, printed in March 2022 when Russia’s invasion of Ukraine threatened Rusal’s 4 million-tonne flow. This time the bullish catalyst is smaller—yet the supply cushion is even slimmer. If Hormuz stays closed past May, the next print could start with a five.
