The price of aluminum rises to a four-year high due to the impact of threats by Trump to block the Strait of Hormuz.

The price of aluminum has soared to its highest point in four years, with US President Donald Trump threatening to block the Strait of Hormuz, which could further disrupt sea shipping. London aluminum prices briefly rose 2%, reigniting the rally caused by supply shortages from previous Middle East conflicts. The US military has announced plans to block all ships entering or leaving Iranian ports or coastal areas starting at 10 a.m. local time on Monday. The Middle East region accounts for approximately 9% of global aluminum production. The region's largest aluminum producer, UAE-based Emirates Global Aluminium, has already cited force majeure clauses for some orders earlier this month after an Iranian attack led to the shutdown of a smelter.
