Aluminum Shortage Deepens as Hormuz Closure Hits Nearly 10% of Global Supply
6 articles · Updated · Bloomberg · May 29
Spot aluminum prices jumped and exchange inventories fell as the market shortage worsened, signaling a tightening squeeze on immediate metal availability.
The disruption stems from the Strait of Hormuz closure and direct attacks on regional smelters, choking flows from a Gulf supply base that accounts for nearly 10% of global output.
Global buyers have been rattled by the conflict, and industry warnings now point to the biggest aluminum shortages in decades if the shutdown drags on.
Even with renewed optimism about easing tensions, the market remains vulnerable because any delay in reopening the strait would keep supply constrained.
With the Strait of Hormuz closed, will this crisis permanently end the era of hyper-efficient global supply chains?
As Gulf conflict chokes supply, can America's defense budget rebuild domestic industry before a consumer goods crisis hits home?
Global Aluminum Crisis 2026: Strait of Hormuz Disruption Triggers Record Prices, Supply Chain Shocks, and Long-Term Market Volatility
Overview
In May 2026, the global aluminum market faced a severe crisis as commercial traffic through the Strait of Hormuz nearly stopped, despite official statements that it remained open. This chokepoint disruption, combined with direct attacks on key Gulf smelters, sharply reduced aluminum supply. Before the crisis, the Strait was a vital route for petroleum and critical commodities like aluminum and helium. The sudden 95% drop in vessel traffic led to immediate shortages, soaring prices, and exposed the world’s heavy reliance on Middle Eastern production. These events triggered widespread industrial and economic impacts, highlighting deep vulnerabilities in global supply chains.
