How the Iran War Is Triggering a Global Aluminum Shortage

The ongoing war in Iran has triggered a global aluminum crisis, manifesting in everything from disappearing consumer goods in Asia to increased cost pressures in the United States. While the conflict is often viewed through the lens of oil and energy, the disruption of aluminum production and shipping has created a ripple effect across multiple industrial sectors.

In India, the crisis has become visible on retail shelves, where Diet Coke cans have reportedly begun to disappear. Because the beverage is sold only in aluminum cans within the country, the supply is entirely dependent on the stability of the global metal market, which has been destabilized by the conflict in the Middle East.

Middle East Production and Strategic Disruptions

The Middle East has established itself as a global hub for aluminum production due to its access to cheap and abundant power, which is essential for the energy-intensive process of refining bauxite. The region possesses the capacity to produce 7 million metric tons of aluminum annually, representing 9 percent of the world’s production capacity, with 75 percent of that output intended for export.

Since fighting began in late February 2026, the supply chain has faced severe interruptions. The situation worsened when Iran began restricting ship traffic through the Strait of Hormuz, a move that hampered the ability of Gulf plants to both import raw materials and export finished aluminum. In response to the instability, smelters in Bahrain and Qatar were shut down.

The crisis intensified on March 28, 2026, when Iran’s Islamic Revolutionary Guard Corps conducted drone and missile attacks on two aluminum facilities in the region. One of these targets, the Al Taweelah plant in Abu Dhabi, which produced 1.6 million tons of aluminum last year, has been completely shut down. These strikes resulted in a hold on approximately 3.2 million tons of the world’s aluminum supply.

These disruptions have driven prices higher globally. By April 2026, the base price of a ton of aluminum surpassed $3,600, reaching a four-year high.

Impact on Asian Economies

Asian economies, which rely heavily on Gulf supplies, are experiencing the most immediate shortages. In Taiwan, semiconductor manufacturers are struggling to obtain necessary helium, while Japanese companies are facing a lack of naphtha, a chemical used for various synthetic materials. In Vietnam, shortages of fuel and fertilizer are impacting rice farmers and affecting the global food supply.

India, the world’s second-largest producer of aluminum, is facing a dual challenge. The country depends heavily on the Middle East for scrap aluminum, and domestic factories are reportedly running low. The war in Iran has increased the cost of powering Indian factories, leading companies to slow production. This follows a 2025 move by the Bureau of Indian Standards to tighten regulations on aluminum, which had already decreased the supply of usable metal.

U.S. Market Vulnerability and Buffers

The United States is currently experiencing higher aluminum prices than other regions, a situation compounded by trade policy. In 2025, Donald Trump raised tariffs on aluminum imports, which increased regional prices and reduced the amount of Canadian metal available to American buyers. This shifted U.S. Reliance toward aluminum from Bahrain and the United Arab Emirates, making the U.S. More susceptible to price shocks originating in the Gulf.

Despite these vulnerabilities, the U.S. Has not yet seen the same level of mass shortages as Asian markets. Paul Adkins, managing director of the aluminum-consulting company AZ Global, noted that the U.S. Possesses certain safeguards:

America “has some buffers: inventories, contracted supply, secondary aluminium and metal already in the pipeline,”

While these buffers allow U.S. Companies to continue accessing the metal by paying higher prices, the long-term outlook remains volatile as the metal is critical for everything from airplane fuselages and MacBooks to solar panels and consumer packaging.

Challenges to Recovery

Experts warn that the global supply will not recover immediately even if the conflict ends. Aluminum smelters require significant time and energy to return to operational temperatures after a shutdown.

If you have a big house and there’s a blackout, normally, you should unplug all your appliances to avoid a surge when the current comes back. It’s exactly the same phenomena with a smelter, except that you’re talking about megapower.

As production remains constrained, the economic strain of the war in Iran is expected to extend beyond the energy sector, with companies likely passing increased aluminum costs down to consumers.
