Silver surges on China export ban fears and AI copper demand

Silver prices have surged to 2-month highs, with analyst Ole Hansen pegging $91.50 as a key resistance level. The catalyst includes reports that China has imposed export restrictions on sulphuric acid, a critical input in copper and silver processing. Copper itself has hit a fresh 3-month high near $13,619 per tonne on the LME, only 6% below the January all-time peak near $14,500, driven by dual pressures: traditional industrial demand and a newfound supercycle in hyperscale AI data center construction.

Every megawatt of hyperscale data center infrastructure requires approximately 27 tonnes of copper for transformers, substations, power distribution, cooling systems, and high-capacity cabling. With hyperscalers from OpenAI to Google to Meta racing to expand capacity, copper demand is accelerating at an unprecedented pace. Meanwhile, China's supply-side headwinds are tightening the global copper market. Chinese mining companies like Zhaojin Mining are scouting acquisitions in Africa and Central Asia to secure new reserves, signaling confidence in elevated long-term prices and potentially higher capex cycles.

The supply-demand dynamic is being felt across metals and mining. Silver miners are up more than 5% as a group, with miners outperforming bullion in recent sessions. Small explorers and junior miners focused on copper, silver, and gold have attracted retail interest, with some community calls for accumulation ahead of potential shortage scenarios. Inversely, copper availability fears could pressure industrial names reliant on input cost stability, including tech manufacturers and automotive suppliers outside the AI infrastructure build-out.

Risks to this narrative include a rapid Chinese stimulus or demand destruction from stagflation fears, both of which could ease supply pressure. Additionally, if AI data center capex cycles disappoint or slow unexpectedly, copper demand could soften materially. But for now, technical breakouts combined with structural supply constraints and structural demand increases from AI make the metals story one of the most compelling cross-asset narratives.
