The global copper market is entering a period of unprecedented structural tightness as we move through mid-2026. What was previously discussed as a long-term supply-demand gap has matured into an immediate operational crisis. A rare convergence of a global sulfuric acid shortage, severe weather disruptions in Chile, and a massive surge in AI-driven data center demand has forced analysts to drastically re-evaluate their price targets.
BMI, a unit of Fitch Solutions, has recently issued a significant upward revision to its copper price forecast 2026, raising the expected average price to US$12,700 per tonne. This 6.7% increase: representing an US$800-per-tonne jump: reflects a market struggling to maintain production levels against a backdrop of geopolitical and environmental headwinds. With the International Copper Study Group (ICSG) projecting a refined copper deficit of 150,000 tonnes by year-end, the “red metal” is no longer just an electrification play; it is a critical bottleneck for the global digital and industrial economy.
BMI Forecast: The $12,700/t Target and 6.7% Revision
The revision by BMI serves as a bellwether for the broader industry. While consensus earlier in the year centered around the US$11,000 mark, the reality of 2026 has proven more volatile. The current forecast of US$12,700/t puts copper in a high-sustained territory, driven by what BMI describes as a market “caught between macroeconomic headwinds and tariff uncertainties,” but ultimately buoyed by structural supply fears.
Other financial institutions are following suit. Goldman Sachs has maintained a “floor” price of US$10,000/t, with fair value peaks reaching US$11,500/t, while some bullish analysts at Macquarie suggest the deficit could push spot prices toward US$13,000/t if Chinese export restrictions on key processing chemicals remain in place.
The Sulfuric Acid Crisis: A Chemical Bottleneck
One of the most critical and underreported drivers of the copper deficit impact 2026 is the global sulfuric acid shortage. Sulfuric acid is the lifeblood of heap leaching and solvent extraction-electrowinning (SX-EW) processes, which account for roughly 21% of global mine output.
The crisis stems from several geopolitical and trade-related events:
- China’s Export Ban: In May 2026, China officially halted the export of sulfuric acid to prioritize its domestic agricultural and industrial sectors. As a primary global supplier, this move removed millions of tonnes from the seaborne market.
- Strait of Hormuz Disruptions: Ongoing regional tensions in West Asia have significantly squeezed sulfur shipments passing through the Strait of Hormuz. Since sulfur is the primary feedstock for sulfuric acid production, many refineries in Latin America have seen their inputs halved.
- Operational Curtailments: In copper-rich regions like the Atacama, several leach operations have already begun “economic rationing” of acid, prioritising high-grade ores while leaving millions of tonnes of low-grade material unprocessed.
BMI notes that these acid constraints have forced a reduction in global mine production growth forecasts, dropping from an optimistic 2.8% to a more realistic 2.4% for the 2026 calendar year.
Chile’s Production Woes: Storms and Structural Decline
Chile, the world’s largest copper producer, has faced a disastrous 2026. We previously reported on the monster storm bearing down on Chile’s copper mines, and the resulting damage to infrastructure has been more permanent than initially feared.
The severe weather events in the second quarter led to widespread flooding of pit floors and damage to tailings dam access roads. These environmental challenges are compounded by a structural decline in ore grades at aging assets. State-owned Codelco and private operators alike are struggling to meet original guidance. According to recent data, Chile’s production forecast for 2026 has shifted from a projected 3.7% growth to a net 2% contraction.
Further complicating the supply side are operational incidents at major global hubs. Grasberg in Indonesia and Kamoa-Kakula in the DRC have both reported logistical bottlenecks in early 2026, preventing these “mega-mines” from fully offsetting the losses seen in the Andes.
The AI Demand Pillar: Data Centers as a Structural Force
While supply is faltering, demand is finding a new, aggressive catalyst: Artificial Intelligence. The copper demand ai data centers 2026 narrative has moved from a theoretical trend to a quantifiable market driver.
Modern data centers are incredibly copper-intensive, requiring the metal for power distribution, grounding, cooling systems, and high-speed busbars. Estimates from the Copper Development Association suggest that these facilities use between 20 and 40 tonnes of copper per megawatt (MW) of applied power.
As the global “compute race” accelerates, the total copper consumption attributed strictly to AI infrastructure is expected to hit 475,000 tonnes in 2026. While this represents only a small percentage of the total 28.7 million tonnes of refined copper used annually, it is the fastest-growing segment. Unlike the Chinese property sector, which continues to show stagnation, AI demand is price-inelastic: technology giants are securing supply at any cost to ensure their data centers remain online.
Copper Market Balance: 2026 Outlook
The following table summarizes the shifted dynamics of the 2026 copper market compared to the previous year’s projections.
| Metric | 2025 (Actual/Est) | 2026 (BMI Revised Forecast) | Change % |
|---|---|---|---|
| Average Copper Price (US$/t) | $9,800 | $12,700 | +29.6% |
| Global Mine Production Growth | 3.1% | 2.4% | -0.7% (pts) |
| Refined Copper Demand (Mt) | 27.9 | 28.7 | +2.9% |
| Market Balance (Tonnes) | -50,000 | -150,000 | +200% Deficit |
| AI Data Center Demand (Tonnes) | 310,000 | 475,000 | +53.2% |
Strategic Implications for Operators and Investors
The convergence of these factors creates a “perfect storm” for copper pricing. For operators, the focus has shifted from expansion to optimization. As we highlighted in our 2026 mining technology update, the industry is turning to autonomous drilling and AI-ready processing to squeeze efficiency out of every tonne of ore, given the rising costs of sulfuric acid and energy.
For investors, the story is one of scarcity. The lack of major new “greenfield” projects coming online in late 2026 means that the market must rely on “brownfield” expansions, which are currently being hampered by the acid crisis.
Conclusion: A Tightening Noose
The copper price forecast 2026 is no longer just about the energy transition; it is about a fundamental mismatch between 20th-century supply chains and 21st-century demand. The sulfuric acid bottleneck has exposed a critical vulnerability in how we extract copper, while the storms in Chile serve as a reminder of the increasing climate risks facing the world’s most productive mining regions.
With AI demand providing a robust new floor and traditional electrification drivers remaining steady, the path toward US$13,000/t seems not only possible but likely. Producers who can secure stable chemical supply lines and navigate the increasingly volatile weather patterns of the southern hemisphere will be the primary beneficiaries of this structural bull run.
