Copper’s next structural shortage: project and capex signals for mine planners

30 Second Briefing
Copper is heading into a structural deficit from 2026, with BloombergNEF projecting energy-transition demand to triple by 2045 and a potential 19‑million‑tonne shortfall by 2050 without new mines or major scrap gains, as disruptions at Quebrada Blanca, El Teniente, Grasberg, Las Bambas and Constancia constrain supply. Copper prices are already up 35% this year, driving renewed capex and M&A across Anglo American, BHP, Glencore, Rio Tinto, Vale and Zijin as miners prioritise brownfield expansions, faster permitting and recycling. Parallel outlooks show graphite moving into technical deficit by 2032, while lithium capacity could reach 4.4 Mt LCE by 2035 amid persistent Chinese midstream dominance.
Technical Brief
- BloombergNEF’s Transition Metals Outlook 2025 identifies geopolitical intervention as the dominant force shaping metals markets.
- Ampofo singles out copper, platinum and palladium as facing the slowest capacity additions versus demand growth.
- Supply tightness is already linked to disruptions at Quebrada Blanca, El Teniente, Grasberg, Las Bambas and Constancia.
- Aluminium output remains about 50% China-based, constrained by a government emissions cap limiting further smelter growth.
- Under BNEF’s Economic Transition Scenario, China’s aluminium share falls to 37% by 2050 as India more than doubles production.
- Graphite demand is projected to rise from 2.7 Mt in 2025 to 6.7 Mt in 2050, mainly for Li‑ion anodes.
Our Take
The projected copper structural deficit from 2026 contrasts with the Anglo–Teck merger coverage in our database, where the combined group is expected to hold just under 5% of global copper supply, underscoring how even mega-consolidations barely dent the long-term 19 Mt shortfall implied here.
Recent coverage of the $3 billion Llurimagua copper–molybdenum project in Ecuador, designed for multi-decade output, suggests that even large new South American assets will only partially offset the forecast tripling of energy-transition copper demand by 2045, keeping pressure on operators in Chile and Peru to squeeze more from mature mines like El Teniente and Las Bambas.
Across the 92 keyword-matched pieces featuring copper and platinum, most price-sensitive items focus on short-term volatility, whereas this BNEF outlook pushes planners towards longer-horizon responses such as accelerating scrap systems and diversifying supply chains in regions like Africa and the DRC, where export bans have already driven cobalt prices sharply higher.
