Aluminium Faces Unprecedented Supply Shock Triggered by Middle East Turmoil

Global Aluminium Market Disrupted by Middle East Conflict

Magnitude of the Supply Shock

LAUSANNE, Switzerland, April 21 (Reuters) - The global aluminium market is experiencing a "black swan" event as disruptions due to the Middle East war trigger a supply shock that will lead to major shortages this year, according to the top metals analyst at commodity trader Mercuria.

The region accounts for about 7 million metric tons of annual aluminium smelting capacity, or roughly 9% of the estimated global supply this year. Aluminium is a key material for the transport, construction and packaging industries.

Expert Insights on Market Impact

"The scale of the supply shock we're seeing in the aluminium market is probably the largest single supply shock a base metals market has suffered in the post-2000 era," Nick Snowdon, head of metals and mining research at Mercuria, said on the sidelines of the Financial Times Commodities Global Summit in Lausanne, Switzerland.

"We are already in a 'black swan' event. No one could have foreseen something on this scale," he told Reuters. 

Price Rally and Deficit Projections

Concerns about supplies due to disruptions stemming from the U.S.-Israeli war with Iran fuelled a rally on the London Metal Exchange, pushing aluminium prices to a four-year high at $3,672 a ton on April 16.

Market Deficit Estimates

Mercuria estimates the market will face, at a minimum, a deficit of roughly 2 million tons between now and the end of the year. Snowdon said this estimate may prove conservative, as it assumes a near-term improvement in alumina flows via the Strait of Hormuz will enable some smelters to restart production this quarter.

Inventory and Buffer Limitations

"That shortfall compares with about 1.5 million tons of visible inventory and just over 3 million tons of total global stock, including non-visible units, leaving the market with limited buffers," Snowdon said.

A larger deficit is possible if the conflict is extended and flows of alumina - a feedstock for aluminium production - to the Gulf are limited, he added.

Global Supply Chain Vulnerabilities

Middle East aluminium cannot easily be replaced. In China, the world's top producer, there is an annual output limit of 45 million tons, while the U.S. and Europe have little idled capacity that could return.

Snowdon said the U.S. and Europe were particularly exposed to the supply shock because of low stocks.

Import Reliance on the Middle East

Of the 3.4 million tons of primary and alloyed aluminium that the U.S. imported last year, the Middle East accounted for nearly 22%, according to Trade Data Monitor, an information provider.

Europe imported around 1.2 million tons, or 18.5%, of its primary and alloyed aluminium from the Middle East last year, according to TDM.

Rising Premiums and Market Reactions

Premiums paid on top of the LME price for physical metal also have surged, hitting a record $1.14 per lb or $2,521.50 per ton in the U.S. and a nearly four-year high of $599 per ton in Europe early in April.

Key Takeaways

  • Mercuria warns of a rare, unforeseen 'black swan' supply shock in aluminium due to disruptions across the Middle East, impacting around 7 million t or 9% of global smelting capacity (sahmcapital.com).
  • The conflict-driven supply shock may cause a minimum deficit of ~2 million t versus total global stocks just above 3 million t, leaving scant buffer (sahmcapital.com).
  • Aluminium prices have surged to four‑year highs (~$3,672/t on April 16), while premiums in the U.S. and Europe have hit record and near‑record levels, underscoring tight physical markets (sahmcapital.com).

Frequently Asked Questions

What is causing the current aluminium supply shock?
Disruptions due to the Middle East war are triggering a major supply shock, significantly impacting global aluminium production.
How much global aluminium supply comes from the Middle East?
The Middle East accounts for about 7 million metric tons annually, roughly 9% of the estimated global supply in 2024.
How are aluminium prices affected by the supply shock?
Aluminium prices surged to a four-year high on the London Metal Exchange, reaching $3,672 a ton in April.
Which regions are most exposed to the aluminium supply shock?
The United States and Europe are especially exposed due to their low stocks and significant imports from the Middle East.
Could the aluminium deficit increase further this year?
Yes, the deficit may grow if the conflict continues and alumina flows to the Gulf remain limited, reducing production further.
