Teck Resources Slides 2% as Zinc Prices Face China Demand Headwinds

Teck Resources (TSX: TECK-B) dropped 2.02% to $89.59 on Tuesday, underperforming a broadly firmer base metals complex as zinc — one of Teck’s core revenue drivers — came under renewed pressure from weakening Chinese manufacturing data and swelling London Metal Exchange stockpiles. At the current USD/CAD rate of 1.4074, Teck’s share price translates to approximately C$126.10, still well below the stock’s 52-week high and a painful session for Canadian base metals investors.

Zinc Prices Retreat on LME Inventory Build

Zinc traded near $1.27/lb (approximately $2,800/tonne) on the LME, down roughly 1.8% on the session, as warehouse inventory data showed a sixth consecutive weekly build — total LME zinc stocks now sit above 245,000 tonnes, their highest level since early 2024. Rising inventory is a classic bearish signal for zinc, indicating that physical demand from galvanizers and steel producers is failing to absorb available supply. China, which accounts for nearly 50% of global zinc consumption, reported an October manufacturing PMI reading of 49.3, slipping back below the 50-point expansion threshold and reinforcing concern that the post-summer industrial recovery is losing steam.

Teck’s steelmaking coal and zinc segments together represent the bulk of the company’s adjusted EBITDA, meaning any sustained softness in zinc pricing flows directly to the bottom line. Teck operates the Red Dog mine in Alaska — the world’s largest zinc-producing mine by output — as well as the Trail Operations smelter in British Columbia, making it uniquely exposed to LME zinc swings among TSX-listed miners. Analysts at Scotiabank estimate that every US$100/tonne move in zinc prices shifts Teck’s annual EBITDA by approximately US$90 million.

Broader Base Metals Complex Holds Firmer

Teck’s weakness stood in contrast to a modestly positive day elsewhere in the base metals space. Copper edged up 0.64% to $6.58/lb, supported by tightening South American mine supply and ongoing EV-related demand expectations. Alcoa, a proxy for the aluminum market, gained 0.53% to $41.67, helped by curtailments at smelters in Europe still contending with elevated power costs. Vale SA, the global nickel bellwether, added 0.38% to $13.11, recovering marginally after last week’s sell-off triggered by Indonesia’s announcement of additional nickel ore export quota allocations — a policy move that had flooded the market with supply expectations.

Canadian Macro Context: Trade Policy Adds Uncertainty

Beyond the immediate commodity price moves, Canadian base metals producers face a complicated trade policy backdrop heading into year-end. Residual U.S. tariff structures on Canadian steel and aluminum intermediates — put in place during successive rounds of North American trade friction — continue to weigh on margin visibility for integrated producers like Teck and Sherritt International. Sherritt, which produces nickel and cobalt from its Cuban operations and refines at Fort Saskatchewan, Alberta, has flagged trade-related logistics costs as a persistent headwind in its most recent management commentary. Any fresh escalation in U.S.–Canada trade tensions could disproportionately hit companies with cross-border smelting and refining exposure.

For now, the market’s focus remains on China. A sustained rebound in Chinese PMI above 50 — driven by stimulus spending on infrastructure or a housing market stabilization — would likely be the single most powerful catalyst for a zinc and broader base metals recovery. Until that data turns convincingly positive, Teck and its TSX peers may continue to lag the modest gains seen in copper and aluminum on any given session. Investors will be watching China’s National Bureau of Statistics PMI release for November, due in early November, as the next major signpost.
