Iran conflict impacts global aluminum supply chain as the Middle East’s top aluminum producer shuts down refinery after Iranian attack.
```
Against the backdrop of escalating tensions in the Middle East, Iran’s attacks on key industrial facilities in the Gulf region have begun to impact global commodity markets.
According to reports on Wednesday, April 1, after its plant was hit by Iranian missiles and drones over the weekend, the main smelter of Emirates Global Aluminium (EGA)—the largest aluminum producer in the Middle East—located in Abu Dhabi, has been forced to suspend operations.
After the news broke, London Metal Exchange (LME) aluminum futures prices surged about 2% intraday, with copper and other industrial metals rising in tandem, indicating the market is beginning to factor in broader supply risks. The share price of Alcoa (AA) in the US market quickly expanded its gains in early trading, up over 7% by midday. Another US aluminum firm, Century Aluminum (CENX), also rose more than 7% at midday.
Market participants believe this shock has spilled over from the energy sector to the industrial metals supply chain. With transport disruptions in the Strait of Hormuz, there are dual concerns about “supply shock + inflation rebound,” making it one of the key drivers behind recent global financial market volatility.
Iran’s assaults on Middle Eastern industrial facilities have pushed market shocks beyond oil into industrial metals, with aluminum becoming the first “flash point.” As supply chain vulnerabilities are magnified, linkage risks among mining, energy, and manufacturing sectors are rising, and global markets are facing a new round of supply-side shocks driven by geopolitical conflict.
EGA Smelter Attacked and Shutdown, Abrupt Contraction in Middle East Aluminum Supply
According to Wednesday’s reports, insiders revealed that EGA’s Al Taweelah smelter in Abu Dhabi was forced into emergency shutdown after Iranian missile and drone attacks caused a power outage. Some potlines experienced “uncontrolled shutdowns,” resulting in metal solidifying inside equipment and causing severe damage.
Meanwhile, large local smelters like Bahrain Aluminum (Alba) recently confirmed being attacked or forced to cut production. Both factories are significant global suppliers, each holding annual output of roughly 1.6 million tons in 2025.
Analysts noted that, coupled with earlier production cuts at Qatar’s joint-venture aluminum smelter Qatalum, about 3 million tons of annualized capacity in the Middle East could be affected—almost half the region’s aluminum output—marking a “significant escalation” in supply disruption.
Hormuz Strait “Choked” – Energy Shock Spills Over: Inflation Transmission from Oil to Metals
Beyond a single plant shutdown, the bigger risk lies in systemic disruption to the supply chain.
Middle Eastern aluminum smelters are highly reliant on imported alumina, and the Hormuz Strait is the key transport route. Research institutes point out that if the strait remains restricted, up to 60% of the region’s alumina supply could be cut off, further forcing smelters to reduce or even halt production.
This chain means that the shock is not only limited to smelting, but will also spread upstream to mining (bauxite, alumina) and downstream to manufacturing (automotive, aviation, construction), forming a typical “resource—smelting—manufacturing” multi-layer shock.
It’s worth noting this shock is not happening in isolation, but as a result of the interplay between energy and metal markets.
Previously, market participants were already worried about oil transport interruptions due to tense conditions in Hormuz. The aluminum sector is itself a typical high-energy-consuming industry, so rising electricity and natural gas prices will further increase production costs.
Therefore, the current shock is transmitted through three pathways:
- Energy price increases → driving up smelting costs
- Transport disruptions → raw material shortages
- Facility damage → direct loss of production capacity
The combination of these three has significantly amplified the risk of global “cost-push inflation.”
Market Outlook: Supply Gap May Be Long-Term
Analysts expect that if the conflict persists and the Strait of Hormuz cannot resume navigation soon, the global aluminum market may see a notable supply gap by 2026.
On one hand, the Middle East accounts for about 9% of global aluminum supply and is an important source for manufacturers in Europe, Asia, and the US; on the other hand, it will be difficult for other regions to fill the gap quickly in the short term.
More critically, geopolitical uncertainty is on the rise. The US has stated it will make resumption of Hormuz navigation a key condition for adjusting military actions, meaning the duration of the conflict remains highly uncertain.
