- Zinc prices rose approximately 1.8% to $1.42/lb on the LME as on-warrant inventory stocks fell below 180,000 tonnes, a multi-month low.
- Teck Resources (TSX: TECK.B) gained 2.05% to $89.98 CAD, directly benefiting from its Red Dog mine and Trail smelter zinc exposure.
- China’s official manufacturing PMI returned to expansion at 50.4 in July, lifting sentiment across base metals and spurring short-covering in zinc.
- Every $0.10/lb gain in zinc price adds an estimated $60–$80 million CAD to Teck’s annual EBITDA, per sell-side sensitivity models.
Teck Resources (TSX: TECK.B) jumped 2.05% to $89.98 (approximately $124.67 CAD) on August 18, 2026, leading the TSX materials sector higher as zinc prices firmed on a meaningful drawdown in London Metal Exchange inventories. Zinc traded near $1.42 per pound (roughly $3,130 per tonne) on the LME, up approximately 1.8% on the session, as available on-warrant stocks slipped below 180,000 tonnes — a level not seen since early spring.
The inventory draw is being driven by a combination of forces: smelter curtailments in Europe, where elevated energy costs have kept zinc refining capacity offline, and a pickup in galvanized steel demand from China’s construction sector. LME zinc warehouses have shed nearly 35,000 tonnes over the past six weeks, a pace that has historically preceded more sustained price rallies. Cancelled warrants — a forward indicator of physical metal departing LME sheds — rose to 12% of total stock, a notably elevated reading.
China PMI Offers a Rare Dose of Optimism
China’s official manufacturing PMI for July printed at 50.4, edging back into expansion territory for the first time in three months and reinforcing the demand narrative for base metals broadly. Zinc consumption in China is heavily tied to galvanized steel used in real-estate and infrastructure projects — sectors that Beijing has been actively stimulating through targeted fiscal transfers to local governments. While the recovery remains fragile, the PMI reading was enough to shift trader positioning, with net speculative short positions on LME zinc unwinding sharply through the Asian session.
Copper, by contrast, slipped 0.67% to $6.56 per pound on the day, suggesting the move in zinc is metal-specific rather than a broad base metals rally. That divergence underscores the tightening supply picture unique to zinc — a market where mined concentrate supply has been structurally constrained since the closure of several major Australian mines in the early 2020s.
Teck’s Zinc Exposure Makes It the Direct Beneficiary
Teck Resources is one of the world’s largest zinc producers, with its Red Dog mine in Alaska and operations at the Trail smelter in British Columbia making the company uniquely leveraged to zinc price moves. Trail, one of the largest fully integrated zinc and lead smelting and refining operations in the world, processes concentrate from Red Dog and third-party sources, giving Teck a margin-on-margin benefit when zinc prices rise. At current spot prices, each $0.10/lb improvement in realized zinc price adds an estimated $60–$80 million CAD to Teck’s annual EBITDA, according to sell-side sensitivity models.
Teck’s share price has now recovered more than 18% from its June 2026 low of $76.20, fuelled by improving zinc fundamentals and the company’s ongoing transition following the divestiture of its steelmaking coal business. With a leaner, metals-focused portfolio — zinc, copper, and energy — Teck is increasingly being repositioned by institutional investors as a pure-play critical-metals vehicle ahead of anticipated EV and green-infrastructure demand cycles.
What to Watch
Traders will be monitoring LME zinc inventory reports through the remainder of August, with a further drawdown below 160,000 tonnes likely to push prices toward the $1.50/lb resistance level. On the macro side, China’s August PMI — due in early September — will be the next key catalyst. Any deterioration back into contraction could reverse the recent optimism quickly. For Canadian investors, Teck’s Q3 2026 production report, expected in mid-October, will be the next hard data point on whether Red Dog output is tracking to full-year guidance.
