StoneX TV: What Base Metals Tightness Means for Copper Smelter Margins
The base metals outlook hinges on supply, as negative copper treatment charges and thin stocks offset a firmer U.S. dollar and soft China demand. Natalie Scott-Gray, StoneX Senior Metals Analyst EMEA & Asia, explains why supply risks across copper, zinc, aluminum and nickel are outweighing macro headwinds. Copper smelters are squeezed by negative treatment charges and falling Chinese sulfuric acid prices, while wage talks at BHP's Escondida mine add upstream risk. Trafigura's review of its Budel zinc smelter tightens supply outside China, and London Metal Exchange aluminum stocks sit at their lowest since early 2025. In Indonesia, drought has cut nickel pig iron output even as global nickel inventories hold at record highs.
