Copper Rebound Signals Growth Resilience Amid AI Volatility and Supply Tightness

Copper prices rebounded 1.2% on the London Metal Exchange on December 15, 2025. This followed a sharp 3% selloff the previous session, triggered by volatility in the AI sector. The move highlights the persistent link between metal markets and broader tech sentiment, creating vulnerability for short-term positioning. Despite the rebound, investor caution remains warranted. The resurgence comes as market participants increasingly pivot toward expectations of tighter supply conditions in 2026. Gains in zinc and aluminum prices alongside copper provide evidence of resilience across the industrial metals sector. While analysts maintain a bullish outlook, forecasting a 2026 deficit, the metal's susceptibility to swings in U.S. tech valuations means the near-term sentiment remains fragile.

Structural Demand Drivers and Penetration Rates

Building on earlier observations of supply disruptions, demand fundamentals remain robust as electrification and renewables continue expanding. Utility-scale projects and grid upgrades are driving steady 2.8% annual copper consumption growth in these sectors, according to UBS analysis. This momentum is amplified by electric vehicles, where cumulative demand is projected to surge 24% to 42.7 million tonnes by 2035. Data center expansion for artificial intelligence infrastructure adds volatility risk-copper intensity per facility remains uncertain amid shifting deployment timelines and regional policy differences. Despite these variables, the long-term trajectory shows penetration rate acceleration across critical infrastructure applications, though defense spending fluctuations could create near-term demand turbulence if budget allocations shift.

UBS projects a widening copper supply deficit, forecasting a 230,000-ton gap in 2025 and 407,000 tons in 2026. This growing imbalance stems from production slowdowns and falling inventories, even as demand expands at 2.8% annually. Major mine disruptions-including operations at Grasberg, Chile, and Peru-have become key constraints on supply growth.

The deficit-driven tightness has pushed copper prices up more than 30% this year, despite recent volatility linked to AI sector swings. While demand from electrification, renewables, and data centers has created near-term strength, the market remains vulnerable to sentiment shifts, as seen in a 3% selloff following AI-related market fluctuations.

Underfunding of new mines and industry focus on mergers rather than greenfield projects further restricts supply capacity. This chronic underinvestment compounds existing disruptions, creating a structural gap between supply growth and accelerating demand from energy transitions and defense spending. Risks persist around production delays from permitting issues, demand shocks from economic slowdowns, and policy shifts like potential tariffs that could disrupt trade flows.

Analyst Forecasts and Growth Thesis Validation

UBS analysts now project copper prices could climb to $11,500–$13,000 per ton through 2026, citing persistent mine disruptions and accelerating demand from electrification projects. Their model forecasts a widening supply gap, with a 407,000-ton deficit looming in 2026, driven by inventory drawdowns and slower production growth despite surging renewable energy adoption.

J.P. Morgan echoes this bullish outlook, targeting $12,500 per metric ton by mid-2026, though their deficit estimate stands at 330 kmt-a 17% smaller shortfall than UBS's projection. Both banks note U.S. tariff-induced premiums and tight warehouse stocks as near-term catalysts, with data center expansion and constrained Chinese smelting output further tightening markets.

While geopolitical tensions and macroeconomic volatility pose modest headwinds, growth tailwinds appear stronger. Electrification mandates and infrastructure investments globally are accelerating copper consumption faster than new supply can materialize. The sector's penetration rate continues rising, with renewable energy projects now driving over 40% of demand growth. That structural shift-coupled with inventory levels at decade lows-suggests current price strength reflects lasting fundamentals rather than fleeting speculation.
