Analyst Views on Copper’s Role in the AI and Electrification Story
“Copper’s surge to fresh all-time highs is a timely reminder that the AI story is not just about chips and software,” said analyst Matt Britzman at Hargreaves Lansdown.
According to Britzman, copper futures were supported during the session by stronger demand from China and intensifying worries over supply, set against a context of firm overall demand.
“For investors, that gives the rally a broader read-across, especially for mining stocks that have spent the past couple of years leaning into copper as the next major growth commodity.
“The question now is whether supply can keep up, because if demand from China, electrification and AI infrastructure continue to build, copper could remain one of the clearest ways for miners to prove they have growth beyond the old iron ore cycle.”
Demand Drivers and Tightening Supply Conditions
Demand for copper has expanded across a wide range of sectors, including power transmission networks, electric vehicles, artificial intelligence data centers and renewable energy installations.
On the supply side, the ramp-up of production from new mines has stayed limited. At the same time, availability of sulfuric acid – a critical input for copper refining – has deteriorated, with the Iran war disrupting shipping routes through the Strait of Hormuz.
China’s subsequent ban on sulfuric acid exports has intensified the squeeze, and copper-related companies rebounded strongly in April as supplies of both diesel and sulfuric acid became tighter.
Long-Term Outlook and Structural Tailwinds
Sprott said long-term sentiment remained positive. “Looking beyond the near-term buffer, Sprott believes the Iran conflict is reinforcing a set of structural demand tailwinds for copper, including actions by nation-states to mitigate oil and gas disruptions by shifting toward electrification and alternative energy sources – where copper is positioned to benefit.”
