Aluminium is getting scarcer – but not equally everywhere

"Aluminium is becoming scarce" is a catchy headline, but it needs decoding. The metal is not suddenly disappearing from the global economy, and a strained supply chain does not automatically mean that consumers will no longer receive cans, cars or window frames. What is meant is something more specific: certain grades can be harder or more expensive to obtain in certain places and at certain points in time. For industrial companies, what counts is not only the tonnes produced worldwide, but also available transport routes, contracts, inventories, energy prices and the question of whether exactly the alloy they need arrives on time.

The current pressure has several causes. Aluminium is a base metal with extremely broad uses: it is found in transport vehicles, buildings, packaging and power grids, among other things. Its combination of low weight, malleability and corrosion resistance makes it attractive for many applications. A disruption therefore does not hit just one single industry, but can ripple along many supply chains.

A strained market meets fresh disruptions

The International Energy Agency describes the market as already strained. In its Global Critical Minerals Outlook, it points out that prices for base metals such as aluminium, copper and tin rose by around a third between January 2025 and April 2026. The current geopolitical situation has sharpened that strain: according to the IEA, the Middle East produces around eight percent of the world's aluminium. Production cuts at several smelters and restrictions around the Strait of Hormuz therefore weighed on a market that had little buffer.

That is an important difference from the claim of a general raw materials shortage. Aluminium can still be produced and traded globally. But when a significant production and transit region drops out or supplies only to a limited extent, the market has to redirect volumes. That costs time and money. Producers and processors cannot immediately replace every missing delivery with other countries of origin, other ports or other material grades. That is why prices and regional premiums often react faster than the visible supply in retail.

Demand also remains a factor. Aluminium is needed for electrification, renewable energy, aerospace and lighter vehicles. The EU therefore lists bauxite, aluminium oxide and aluminium together as strategic and critical raw materials. That is not a forecast of an imminent collapse, but a political assessment: the materials are economically important, supply can be vulnerable to disruption, and expanding output takes time.

The answer is more resilience
