Market Impact

The market is impacted by reduced aluminum supply from the Middle East due to disruptions in the Strait of Hormuz and production cuts by major smelters like Aluminium Bahrain and Hydro ASA===Qatalum. This has led to a significant increase in aluminum prices on the London Metal Exchange, reflecting fears of shortages and supply chain volatility.

Event Summary

Aluminium Bahrain (Alba), the world's largest aluminum smelter on one site, has initiated a controlled and safe shutdown of Reduction Lines 1, 2, and 3, which account for 19% of its total production capacity. This strategic operational measure is in response to ongoing supply and transit disruptions affecting the Strait of Hormuz, which has effectively closed for shipping and prevented Aluminium Bahrain from exporting metal or receiving key raw materials like alumina. The company had previously issued force majeure on March 4. The disruptions are linked to the U.S.-Israeli war on Iran. This situation has also impacted other regional smelters, with Hydro ASA===Qatalum in Qatar reducing operations due to gas supply suspensions. The market has reacted with aluminum prices on the London Metal Exchange rising to a nearly four-year high.
