Aluminum Prices Surge 15% in Biggest Squeeze Since 2007 on Hormuz Closure

Key Facts

1Aluminum prices jumped 15% in the biggest market squeeze seen since 2007.

2The closure of the Strait of Hormuz has driven a supply shock reshaping metal market assumptions.

Global metal markets witnessed a dramatic shift as aluminum prices jumped 15%, marking the most significant market squeeze since 2007. According to reports, this sharp rally was triggered by the closure of the Strait of Hormuz, a vital waterway for global trade, causing a supply shock that has fundamentally reshaped metal market assumptions. This sudden move underscores the extreme sensitivity of industrial inputs to escalating geopolitical tensions.

This surge comes at a critical time for the global manufacturing sector, placing additional pressure on industry giants such as Alcoa (AA) and Rio Tinto. Per market data on peer performance, this supply deficit is expected to drive production costs significantly higher, as the affected region serves as a primary artery for energy and minerals. Analysts suggest that a prolonged closure could threaten profit margins in the aerospace and automotive sectors, which rely heavily on aluminum.

Traders should closely monitor aluminum price levels, which hit a multi-year peak at the close of May 29, 2026, while watching for any official statements regarding the reopening of shipping lanes. Looking ahead at the economic calendar, the U.S. Core PCE Price Index, which printed at 0.2% on May 28, 2026, will remain a key catalyst for broader commodity risk appetite in the coming days.
