Silver and copper surge on AI data center demand, China export bans

Silver and copper have broken out of long consolidation ranges, with silver approaching the 91.50 level flagged by analyst Ole Hansen as key resistance. The rally is grounded in two distinct catalysts. First, the AI capex cycle requires enormous quantities of copper for transformers, substations, power distribution, cooling systems, and high-capacity cabling. Estimates suggest each megawatt of hyperscale data-center infrastructure needs roughly 27 tonnes of copper. As hyperscalers ramp buildout globally, demand for these metals is inelastic and structural.

Second, China has imposed export restrictions on sulphuric acid, a critical input for metallurgical processing. This supply shock is raising spot premiums; silver and copper mining stocks are trading 20-26% above spot prices as physical supply tightens. The backdrop of persistent geopolitical risk (Iran conflict, potential Taiwan escalation) is also lifting hard assets as safe-haven hedges alongside traditional gold.

Copper has pushed to 13,619 per tonne on the LME, a 3-month high and only 6% below the January all-time peak near 14,500. Commodity shipping is benefiting from the tight supply dynamic, and investors are rotating into precious metals and industrial metals ETFs ahead of the key USDA report and Trump-Xi summit, both expected to support commodity prices if trade deals materialize.

However, the rally faces headwinds from potential demand destruction if the Fed maintains hawkish rates for longer than expected (CPI is due Wednesday). Copper is also vulnerable to a Chinese economic slowdown if stimulus expectations fade. Real estate weakness in China could dampen infrastructure demand. Skeptics also note that the silver and copper surge is benefiting from short covering and leverage, not fundamental buying from end-users, suggesting fragility if macro sentiment shifts.
