Copper's 2035 supply gap narrows—but the execution opportunity remains
The IEA now projects a 25% copper supply deficit in 2035, down from around 30% as projects advance in the DRC and Zambia. The commercial opportunity is shifting from headline scarcity toward project delivery, debottlenecking, recovery improvement and lifecycle support.

What happened
The IEA Global Critical Minerals Outlook 2026 estimates that the projected copper supply deficit in 2035 has narrowed from around 30% to 25%. The improvement reflects progress in the announced project pipeline, particularly in the Democratic Republic of the Congo and Zambia, but expected supply still falls short of primary supply requirements in the stated-policies scenario.
Why it matters
A smaller projected gap does not remove the need for new capacity or better performance from existing assets. Copper demand remains supported by electricity networks and increasingly electrified, digitalised and automated systems, while mine development continues to face long lead times, infrastructure constraints, capital intensity and operating complexity.
Commercial implications
For equipment and technology providers, the strongest near-term opportunities may sit in brownfield expansion, debottlenecking, recovery improvement, energy and water efficiency, automation, reliability and local service readiness. Winning work will depend on translating technical performance into measurable production, risk and lifecycle-cost outcomes.
Recommended next steps
Map priority copper projects and operating assets by project stage, EPC involvement and procurement window.
Build quantified value cases around throughput, recovery, availability, energy intensity and lifecycle cost.
Assess the local service, parts, training and compliance capability required before customer engagement.
The headline has improved, but it has not disappeared. In its 2026 outlook, the IEA reduced the projected 2035 copper supply deficit from around 30% to 25% as new projects advanced. That still leaves a substantial gap between expected mine supply from existing and announced projects and projected primary supply requirements.
Why execution matters more than headline scarcity
A supply gap is not the same as deliverable production. New mines require capital, infrastructure, approvals, skilled people and years of coordinated execution. Existing operations also need to manage ore variability, declining grades and asset reliability. Technologies that shorten ramp-up, remove bottlenecks or improve recovery can therefore be commercially relevant well before a new project reaches full production.
Where equipment suppliers should focus
The practical opportunity is to connect a specific operating constraint with a measurable outcome. Suppliers should prioritise accounts where they can demonstrate higher throughput, improved recovery, lower energy or water intensity, greater availability, safer maintenance or stronger lifecycle economics—and support those claims with local service and delivery plans.
