LONDON — Global copper supply chains are facing heightened geopolitical risks as surging demand from artificial intelligence infrastructure strains already concentrated production and processing networks, industry analysts said.
Major producers and traders are monitoring disruptions in key mining regions and refining bottlenecks, particularly as data centers powering AI technologies drive additional consumption. Copper prices have risen significantly in recent months amid tight supply and expectations of further growth in demand.
Copper is essential for electrical wiring, power transmission and data center infrastructure. S&P Global projected that global copper demand could rise substantially by 2040, driven by core economic needs, the energy transition, AI and data centers, and defense spending. The supply chain is geographically concentrated, with an estimated 40% to 50% of smelting and refining capacity in China, amplifying vulnerability to policy changes and trade tensions.
Mining output faces challenges including declining ore grades, long development timelines for new projects — averaging about 17 years from discovery to production — and regulatory hurdles in countries such as Chile and Peru, which together account for a large share of global supply. The Democratic Republic of Congo is another key source but carries risks related to political instability.
“Bullish sentiment is being driven by the narrative around tight supply, supported by macro news flows,” Macquarie analyst Alice Fox said.
China dominates both consumption and refining. It accounts for a majority of global refined copper use and has significant influence over processing, with reports of export licensing requirements and concentrate imports affecting availability elsewhere. Western efforts to diversify supply chains remain in early stages.
Analysts from S&P Global warned of a potential multi-million-tonne supply shortfall by 2040 without new investments in mines and processing. AI data centers represent an emerging demand vector, alongside traditional drivers like electric vehicles and renewable energy infrastructure.
Industry participants are exploring recycling and alternative sourcing, though primary mined supply remains critical. No immediate widespread shortages have been reported, but market participants continue to assess risks from geopolitical developments, including trade policies and regional conflicts.
Copper market dynamics are expected to remain a focus for governments and companies seeking to secure supplies for technology and energy goals. Further updates on production guidance from major miners and policy announcements from key producing nations are anticipated in coming months.
