Andy Home: The aluminum supply shock has revived long-idled Western Smelters

The Iran War has caused a supply shock that is reviving the old Western aluminum smelters.

Magnitude 7 Metals in the U.S. is reactivating its New Madrid smelter located in Missouri.

Over the Atlantic, Norwegian producer Hydro announced the partial restart of the Slovalco joint-venture smelter.

The two plants were idled due to low aluminum prices and a spike in energy prices that followed the Russian invasion of Ukraine.

Washington and Brussels are both desperate to reduce their reliance on an import of a metal used in a wide range of industries.

The return of these zombies smelters will not have a big impact on the global aluminium market, but it does show how much the market has changed since the Middle East conflict erupted in February.

Back from the Dead (Again)

New Madrid began operating in 1971 under the ownership of Canada Noranda, which had a production capacity of 263,000 tons per year.

Magnitude 7 Metals, a privately-owned company, reactivated the plant in 2018, but it closed abruptly in 2024. The smelter was the most polluting plant in the nation in 2019.

The plan is to restart one 75,000-ton-per-year(tpy) potline by ?the end of the year, with the possibility of operations ramping up further in 2027.

New Madrid's revival has been undoubtedly helped by President Donald Trump's decision to double import tariffs last year from 25% to 50%.

The premium for U.S. deliveries has risen to $2,375 a ton over London Metal Exchange (LME basis price).

The rise in LME's basis price, from $2,200 per tonne at the beginning of 2024, to $3,165 per tonne today is equally important to New Madrid’s revival, even after the recent, and perhaps premature, unwinding of the war premium.

SLOVAK REVIVAL

The Slovalco Plant, which is owned by Hydro, a 55.3% stake, and by Penta Investments Group (focused on Central Europe), a 44.7% stake, also plans to restart its 75,000-ton capacity.

The decision is based on a new deal for power supply with the state-owned hydropower utility Vodohospodarska Vystavba, and a compensation plan for indirect carbon costs in accordance with the EU Emissions Trading System.

This latter still requires approval by the European Commission.

Europe has lost half its primary aluminium melting capacity since 2022. This makes the restart a major win for Slovakia and Europe.

High power costs combined with EU emissions regulations still create a challenging operating environment for aluminium smelters that are power hungry.

Hydro stated that the restart of the remaining capacity of 100,000 tons at Slovalco will "depend on (ETS framework conditions) beyond 2030, combined with additional electricity contracts."

WINDOW OF OPPPORTUNITY

Gulf Aluminium production has fallen by 2 million tonnes annually due to the war in Iran, a result of both direct missile strikes on two plants as well as logistical constraints at others.

The market has gone from years of surplus to a deficit in a matter of weeks.

LME inventories have been used to fill in the supply-chain holes, and total inventory (including off-warranty metal) is now below 400,000 tons.

The war has highlighted existing import dependence in the U.S. as well as Europe, creating a window for idled capacities to be fired up again.

It is irrelevant how long the window remains open.

There are other parts of the global supply chains that also react.

China is increasing exports of semi manufactured products like?bars, rods, and foils to take advantage of the West's metal shortage. Exports of products fell 9.4% in comparison to 2024, but increased by 10% during the first five months of 2018. May's total of 595,000 tonnes was the highest since November 2024.

Chinese investors are also investing in the construction of new smelting capacities in Indonesia.

According to Macquarie Bank, a new project called Juwan, with a 270,000 tpy capacity, reached its full capacity in the month of January.

Export Genius' trade data platform, Export Genius, reports that the joint venture Adaro, which produces 500,000 tpy, exported its first shipments in July.

Adaro wants to increase its capacity to 1.5million tpy as part of an overall?national production boom that could result in over 10 million new tons of annual capacity being ramped up in the coming years.

The combined restarts of 150,000 tpy at New Madrid, Slovakia and Slovakia are placed in context regardless of their political significance.

What happens in the Middle East will determine a lot of what comes next.

The LME aluminium prices has fallen aggressively due to'signs of deescalation' and hoped for normalisation in the Gulf smelters.

It's beginning to look optimistic, given the renewed U.S. Bombing Campaign and Iranian Retaliation.

For now, the window for further restarts is still open.
