Copper Hits 15-Year High Amid Supply Constraints

Copper prices have reached a fresh nominal record, driven by AI infrastructure demand and supply disruptions that are raising costs for global electrification projects.
Copper has reached a new nominal price record. The metal is currently trading at a 15-year high in constant dollar terms. It is nearing the peak levels seen in 2011. This price action is driven by demand from AI data centres and electricity grid expansion. Tariff-driven stockpiling has further amplified recent gains. Supply disruptions add to the pressure on prices.
Kyle Dahms of the National Bank of Canada notes that the real price is approaching its highest level since the mid-1970s. The demand backdrop remains supported by construction for artificial intelligence infrastructure. Grid expansion projects require significant copper input. These factors are creating structural tightness in the market. The price increase acts as a cost factor for energy projects.
Supply Disruptions Impact Processing Costs
Shipment restrictions through the Strait of Hormuz have affected sulphur supplies. Sulphur prices have more than doubled since the start of the year. Sulphur is a key feedstock for sulphuric acid. This acid is used in specific copper processing methods. The rise in input costs adds to the overall expense of copper production.
Geopolitical fragmentation is making supply chains less reliable. The market faces constraints that are not purely demand-driven. Processing costs are rising alongside raw material prices. This combination squeezes margins for downstream users. The supply side is under pressure from multiple fronts.
Electrification Projects Face Higher Expenses
Higher copper prices increase the cost of power grids. AI data centre construction becomes more expensive. Broader electrification projects face financial headwinds. The price rise acts as a tax on investment. This investment is intended to support future economic growth.
The National Bank of Canada analysis highlights the link between price and infrastructure. Costs are rising just as supply reliability decreases. This dynamic poses a challenge for energy transition goals. Project budgets must account for sustained high metal prices. The economic impact is spreading beyond the commodity market.
AI Demand Drives Structural Tightness
Data centre construction is a primary driver of copper demand. These facilities require extensive electrical wiring and cooling systems. Grid expansion is necessary to support this load. The demand is linked to long-term technological trends. This creates a persistent floor for copper consumption.
The market is reacting to both demand and supply shocks. AI infrastructure is consuming more copper than previous technological shifts. Supply disruptions are reducing available inventory. The result is a tight market with limited buffer. Prices reflect the balance of these opposing forces.
