Copper Hits $6.62/lb as AI Datacenter Demand Tightens Global Supply

Copper rose to $6.617 per pound on Tuesday, a 0.48% gain that pushed the red metal to its highest level in six weeks, driven by accelerating demand from AI datacenter construction and persistent supply-side headwinds out of South America. Translated to Canadian dollars at the prevailing USD/CAD rate of 1.4253, copper is now trading at approximately $9.43/lb CAD — a level that meaningfully improves project economics for domestic producers eyeing development decisions.

AI and Datacenters: The Demand Driver No One Saw Coming

Copper’s traditional demand pillars — EV motors, grid infrastructure, and industrial manufacturing — are well understood by commodity markets. What is increasingly reshaping the price ceiling for copper is the explosive buildout of AI datacenters across North America and Southeast Asia. A single hyperscale AI datacenter can consume between 15 and 25 tonnes of copper in busbars, wiring, and cooling infrastructure alone, according to engineering estimates from major construction firms. With Microsoft, Google, and Amazon collectively announcing over US$200 billion in datacenter capital expenditure for 2025–2027, copper’s role as the connective tissue of the digital economy is no longer speculative — it is contractual.

Grid expansion compounds this picture. Canada’s own national grid modernization program, accelerated under federal clean energy mandates, requires an estimated 400,000 tonnes of additional copper cabling over the next decade. That structural demand floor is keeping traders reluctant to short copper even during brief macro-driven selloffs.

Chile Supply Pressure: Grade Decline Bites Codelco

On the supply side, Codelco — the Chilean state copper giant and the world’s single largest producer — reported a 4.1% year-over-year decline in average ore grades across its legacy open-pit operations in Q3 2026. Lower grades mean more rock processed per pound of copper produced, raising costs and trimming output even without a single strike or weather event. Peru, the world’s second-largest copper producer, is simultaneously navigating community protests near the Las Bambas mine, where road blockades have intermittently disrupted concentrate shipments since late September. Analysts at BMO Capital Markets estimate the combined Chilean grade deterioration and Peruvian logistics friction could shave 180,000 to 220,000 tonnes off annualized global supply — enough to keep the market in a structural deficit through mid-2027.

Teck Resources Trades Lower Despite Copper Tailwind

Canadian copper major Teck Resources (TSX: TECK.B) fell 0.98% to $96.80 on Tuesday, a counterintuitive move against the copper price backdrop that traders attributed to profit-taking after the stock’s 14% run over the prior three weeks. Teck’s QB2 copper operation in Chile remains the company’s flagship growth asset, with full ramp-up to nameplate capacity of 316,000 tonnes per year now expected in Q1 2027 after earlier throughput bottlenecks. At spot copper prices converted to CAD, QB2’s projected revenue contribution at full capacity exceeds $4.2 billion CAD annually — a figure that makes the current share price pullback look technically constructive to longer-term investors.

With the copper market balancing an AI-fueled demand surge against structurally declining ore grades in the world’s two largest producing nations, the price trajectory into year-end appears skewed to the upside. Canadian producers with near-term production growth, particularly those with Chilean or Peruvian exposure like Teck, remain pivotal plays for investors seeking commodity leverage in a market that increasingly runs on copper.
