The International Energy Agency has issued one of its most explicit warnings to date regarding the long-term copper supply outlook, projecting in its Global Critical Minerals Outlook 2026 that supply from existing mines and announced projects will fall approximately 25% short of expected demand by 2035. The finding represents a structural gap of significant magnitude, one that the IEA warns will persist through the middle of the next decade and carry far-reaching implications for producers, developers, and investors alike. While the projected shortfall marks a modest improvement from the 30% deficit forecast published in the agency's previous annual report, the IEA emphasizes that the remaining gap is still substantial.
New projects advancing in the Democratic Republic of Congo and Zambia have contributed to narrowing the imbalance, but the agency concludes they are far from sufficient to close it. The overall trajectory of the copper market, as assessed by the IEA under its Stated Policies Scenario, remains firmly oriented toward a material and sustained supply deficit by 2035. The scale of the projected shortfall is considerable.
In a market of copper's size, a 25% gap implies millions of tonnes of unmet demand each year if no additional supply beyond the currently visible pipeline is brought online. The IEA notes that such a gap would typically be resolved through some combination of higher prices, demand destruction, accelerated recycling, or the rapid development of new mines. The latter option, however, is severely constrained by long lead times.
The agency highlights particular structural challenges facing copper compared with other critical minerals, including declining ore grades at existing operations, a slowing rate of new major discoveries, sharply rising capital costs for greenfield projects, and an average time from discovery to production that continues to extend well beyond a decade in most jurisdictions. On the demand side, the IEA identifies several concurrent growth drivers underpinning the deficit projection. Electrification of transport is cited as a core factor, with electric vehicles requiring substantially more copper than conventional internal-combustion-engine vehicles across the electric motor, battery connections, power electronics, onboard wiring, and charging infrastructure.
Power infrastructure expansion, including the build-out of electricity grids, integration of renewable generation, and modernization of transmission and distribution systems, represents an even larger source of incremental demand in many long-term scenarios. The agency also points to the accelerating construction of data centres to support artificial intelligence and cloud computing as an increasingly prominent demand driver in recent forecasts. Conventional end-uses in construction, consumer durables, and industrial equipment continue to provide a stable demand base alongside these structural growth vectors.
Supply-side headwinds are equally well-documented, according to the IEA. Many of the world's largest copper mines are mature and experiencing gradual grade decline, requiring either major expansions or entirely new developments to sustain output. Greenfield copper projects face capital-intensive development processes, lengthy permitting timelines, environmental reviews, community consultations, and significant infrastructure requirements.
In some jurisdictions, these timelines have lengthened rather than shortened in recent years. The IEA's projections already incorporate expected contributions from secondary and recycled sources, meaning the remaining gap must be filled by new primary mined production if demand materializes as forecast. From a market outlook perspective, the IEA's analysis implies that a persistent supply deficit of this scale would, all else equal, be expected to support higher real copper prices over the medium to long term.
The agency acknowledges that copper remains a cyclical commodity subject to influence from global manufacturing activity, Chinese demand, inventory levels, and broader macroeconomic conditions, meaning short-term price movements can diverge materially from long-term fundamentals. Nevertheless, the IEA's assessment reinforces a narrative already gaining traction among several mining companies and independent analysts, who have begun framing the second half of the 2020s and the 2030s as a potential period of copper scarcity. For the investment community, the IEA's findings carry direct implications across the copper mining equity universe, as reported by Canadian Mining Report.
Higher sustained copper prices would generally expand margins for existing producers, particularly those with lower all-in sustaining costs, while making development-stage projects and expansions more economically robust. Assets that were previously marginal at lower price assumptions could move firmly into the money, improving the likelihood of financing and final construction decisions. However, the analysis from Canadian Mining Report cautions that not all copper-exposed companies will benefit equally, with differences in jurisdiction, cost structure, balance-sheet strength, management execution, and project quality expected to drive wide dispersion in returns.
Canada is highlighted as occupying a strategically important position within this global copper landscape. The country hosts significant production capacity, a pipeline of development projects, and a broad ecosystem of exploration companies listed primarily on the TSX and TSX Venture exchanges. In an environment increasingly focused on security of supply and responsible sourcing, the jurisdictional advantage offered by Canada's stable regulatory framework, established mining law, and access to capital markets is identified as a potentially meaningful differentiator.
Producers and developers operating in Canada or similarly low-risk jurisdictions may command valuation premiums relative to peers in higher-risk regions. The IEA and Canadian Mining Report both note several risks and caveats to the central projection. Faster-than-expected project development or technological improvements in mining and processing could increase supply beyond current visibility.
Stronger recycling rates or material substitution could reduce primary demand growth. A prolonged global economic slowdown could temporarily suppress demand. Policy changes, trade restrictions, or resource nationalism could disrupt supply and demand patterns in ways not captured by the Stated Policies Scenario.
The IEA's projection is explicitly characterized as a scenario rather than a guarantee. The 25% copper supply deficit figure projected by the IEA for 2035 underscores a structural gap that the agency warns will shape capital allocation, project prioritization, and price formation across the global copper market for the remainder of this decade and into the next. For the mining industry, the message is one of urgency: more investment, faster project execution, and continued innovation will be required if the world is to narrow the gap further.
The modest improvement from last year's 30% estimate demonstrates that progress is achievable, but the remaining shortfall remains a defining challenge for one of the world's most critical industrial metals.
