The International Copper Study Group (ICSG) has released its 2026 forecast, projecting a refined copper deficit of 150,000 tonnes — the first structural shortage since 2009. The deficit is driven by persistent mine supply disruptions and steady demand growth from electrification, grid investment, and AI data centre construction. (Source: Reuters, ICSG, October 2025)
The ICSG deficit estimate is conservative relative to some bank forecasts. Goldman Sachs had previously forecast a deficit of 200,000-300,000 tonnes for 2026 before revising its price outlook lower in April 2026, citing potential demand-side cooling. Bernstein remains more bullish, forecasting a Q2 2026 peak at $13,500/t with the deficit acting as the primary price driver through mid-year. (Source: Goldman Sachs, Bernstein)
The single largest contributor to the supply shortfall is the indefinite closure of First Quantum's Cobre Panama mine, shut since November 2023. At full capacity, Cobre Panama produced roughly 380,000 tonnes of copper annually — equivalent to approximately 1.7% of global mine supply. The Panamanian government has lost an estimated $3.5 billion in potential revenue during the shutdown. Talks between First Quantum and Panama have failed to produce a restart timeline, leaving a gaping hole in the supply pipeline. (Source: MINING.COM, First Quantum)
LME registered copper inventories stood at 391,900 tonnes as of May 22, 2026, down significantly from levels seen in early 2025. The drawdown reflects both physical tightening and tariff-related reshuffling of global trade flows. LME on-warrant stocks — the material freely available to the market — have fallen even more sharply, raising concerns about deliverability against LME contracts. (Source: Westmetall, LME)
Weaker US dollar conditions and ongoing US-Iran diplomatic talks have added a macro tailwind to copper prices, supporting the LME cash settlement at $13,545/t. However, Goldman Sachs has cautioned that prices above $13,500/t could trigger demand destruction in price-sensitive sectors such as residential construction and consumer appliances, potentially capping further upside.

On the demand side, global copper consumption continues to grow at approximately 2.5-3% annually, with the energy transition accounting for an increasing share. Data centre buildout for artificial intelligence workloads has emerged as an unexpected demand driver, with each large-scale AI facility requiring significantly more copper than traditional data centres for power distribution and cooling infrastructure.
The structural nature of the 2026 deficit distinguishes it from the cyclical surpluses of 2023-2025. With Cobre Panama unlikely to restart before 2027 at the earliest, mine ramp-ups constrained by permitting delays, and concentrate treatment charges at or below zero, the industry is facing a multi-year supply problem that will not be resolved quickly.
Secure 50-60% of H2 2026 volume via LME forwards at current levels near $13,500/t. Use collars to protect the remaining exposure with a floor at $12,000/t and a cap at $14,500/t. Horizon: 3-6 months. Key trigger to watch: LME on-warrant stocks below 250,000 tonnes would signal accelerating tightness and justify increasing hedged coverage to 70%.
