Copper Holds Above $6.55 as AI Datacenter Demand Offsets Chile Strike Fears

Copper settled at $6.5605 per pound on August 18, 2026, a modest decline of 0.66% on the session, yet prices remain firmly elevated in what analysts are calling a structurally tight market. Converted to Canadian dollars at the prevailing USD/CAD rate of 1.3859, that translates to approximately $9.09/lb CAD — a level that makes Canadian copper producers and developers among the most profitable in the company’s recent history.

Teck Resources Surges as Copper Stays Strong

Teck Resources (TSX: TECK.B) was a standout on the Toronto Stock Exchange Tuesday, climbing 2.05% to $89.98 — a sharp outperformance relative to copper’s slight intraday pullback. The divergence signals that equity markets are pricing in longer-term copper fundamentals rather than reacting to daily spot moves. Teck’s QB2 copper mine in Chile, one of the largest new copper operations in the world, continues to ramp toward full production capacity, giving the Vancouver-headquartered miner significant leverage to sustained high copper prices.

Chile and Peru: Strike Risk Keeps Supply Outlook Fragile

Chile and Peru together account for roughly 38% of global mined copper supply, and both countries are navigating elevated labour tensions heading into Q4 2026. At Chile’s Escondida mine — the world’s single largest copper operation, majority-owned by BHP — union contract negotiations are entering a critical phase, with workers citing inadequate wage adjustments relative to copper’s price surge. A full strike at Escondida alone could remove an estimated 1.1 million tonnes of annualized copper supply from the market. In Peru, community protests near the Las Bambas mine have intermittently disrupted trucking routes throughout the year, adding further uncertainty to already thin exchange inventories. London Metal Exchange copper stockpiles stood at a historically low level entering the week, leaving the market with little buffer against a supply shock.

AI Datacenters Are Becoming a Copper Demand Category of Their Own

The energy infrastructure required to power the global AI buildout is rapidly emerging as a discrete and growing copper demand driver. Each large-scale hyperscale datacenter requires an estimated 20 to 30 tonnes of copper for busbars, cabling, transformers, and cooling systems. With over 400 major datacenter projects currently permitted or under construction across North America, Goldman Sachs Commodities Research estimates that AI-related copper demand could add 1 million tonnes per year to global consumption by 2028 — equivalent to roughly 4% of total annual supply. This demand sits on top of the already well-documented copper intensity of EV motors and grid-scale battery storage, where a single electric vehicle uses approximately three to four times the copper of a conventional combustion engine vehicle.

Green Grid Expansion Adds a Second Structural Demand Layer

Canada’s own electricity grid modernization program, accelerated by federal clean energy investment commitments, is absorbing meaningful volumes of copper wire and transformers. Hydro One and BC Hydro have both announced multi-billion dollar transmission upgrade programs in 2026, with copper-intensive high-voltage direct current (HVDC) lines forming the backbone of interprovincial clean energy corridors. For Canadian copper developers — including smaller TSX-V listed companies advancing projects in British Columbia, Ontario, and Nunavut — the domestic demand story adds a layer of offtake certainty that was absent just three years ago.

With supply fragility in the Andes and structural demand from two of the most powerful secular trends of the decade — electrification and artificial intelligence — copper’s long-term bull case remains intact. Tuesday’s 0.66% dip looks less like a trend change and more like a brief exhale in a market with very little room to spare.
