Bank of America Global Research yesterday reported that the US has lost three-quarters of its aluminium smelters, China has capped its aluminium production, US consumers are now having to pay the full 50% tariff, there's a lot of uncertainty about what is happening with the South32 smelter in Mozambique, and the biggest aluminium production increases are coming through Indonesia.
In South Africa, the electricity pricing agreement for South32's Hillside Aluminium in KwaZulu-Natal struck in May reflects the South African government's policy to support strategic industries that create value for the nation. The Hillside smelter's international competitiveness is enabling it to continue to deliver significant benefits to South Africa.
Meanwhile, in the US, it has been a one-way road in terms of aluminium smelters and in China, with a 45-million-ton capacity cap, more smelters are unlikely, Bank of America metals research head Michael Widmer reported during a report on the bank's 2026 metals market outlook.
While the US administration is trying to build new aluminium smelters, Widmer displayed a chart indicating that there is no silver bullet.
Widmer also highlighted the demand from data centres and pointed out that these were reportedly prepared to pay considerably more for the electricity that the aluminium smelters need.
'With all the discussion on tariffs and who is going to invest, it often comes down to just one metric, which is the power cost and the unfortunate reality is that, anecdotally, I think data centres and AI can pay more than three times as much for power than a smelter would want to pay, so there's a lot of competition, and that really puts the aluminium industry in a very difficult position," Widmer noted, while another slide displayed showed that the US was now down to only five aluminium smelters from the more than 20 it had in 1998.
Provided by Bank of America Global Research was an outlook for metals, particularly copper and aluminium, in relation to global economic trends and defence spending, and those participating in the webinar heard that the Chinese government has repeatedly been called on by the Chinese aluminium industry in the past decade to effectively bail the smelters out.
"What happened is that every time there was a positive margin, the Chinese smelters came in, built a lot of capacity, increased production, competed away those positive margins, and ultimately came under pressure of the government.
"But it reached the stage where government said no more of this, we want to have a capacity cap and a 45-million-ton capacity cap was instituted, and that's where we are now.
"A little bit of supply growth is now coming through in Indonesia. Again, in many instances, it's the Chinese operators who can no longer invest in China, and now it's spilling over into the international market.
"But I think that the aluminium market should be able to absorb those. A lot of it potentially goes to China in the end as well," Widmer reported during the webinar covered by Mining Weekly.
"In Europe in July, we saw the first months where every single sector made a positive contribution to aluminium demand in Europe for the first time in almost three years.
"There is a risk that premia in Europe go higher, and force US consumers to also pay up, because some of the Canadian units could, for instance, then end up in Europe.
"I think this competition is why we are starting to see aluminium prices also pushing higher. An additional issue that you have in Europe at the moment is there's a lot of uncertainty about what is happening with the South32 smelter in Mozambique. That's 500 000 t, about 10% of the European use. It doesn't have a power drive, so there's still a risk of losing that supply.
"The othe...
