Strait of Hormuz Closure May Tip Global Economy

Americans are warily eyeing prices at the pump as oil shipments through the Strait of Hormuz grind to a halt amid the threat of Iranian attacks on vessels. The IEA took the unprecedented step of saying it would release 400 million barrels of oil from reserve on Wednesday. But oil is far from the only product for which the world economy is heavily dependent on the shallow, narrow waterway which connects Persian Gulf ports with the rest of the world. From the metals market to agriculture and autos, a de facto closure of the strait would ripple through business sectors and both the U.S. and world economy.
Aluminum is a good example. It is one of the biggest non-petroleum commerce casualties of the U.S.-Iran war. In 2025, the Middle East accounted for roughly 21% of unwrought aluminum imports and 13% of wrought aluminum imports — and those percentages have been rising. Unwrought aluminum is the raw, unprocessed metal in forms like ingots and billets, while wrought aluminum has been mechanically shaped into sheets, rods, or other finished forms used directly in manufacturing.
