30 Second Briefing
Zinc on the London Metal Exchange has surged to $4,107 per tonne, its highest level since June 2022, as LME warehouse stocks have fallen 64% from about 264,000 tonnes in December 2024 to roughly 95,000 tonnes, the lowest available metal since April 2023. While tightness is concentrated in Western LME warehouses, Shanghai Futures Exchange zinc inventories have risen, pointing to regional dislocation rather than uniform scarcity. HSBC forecasts 2026 mine output at 12.5 million tonnes, down 2.1% year-on-year, with Teck, Glencore and Nexa shares up 46–60% since January 2026.
Technical Brief
- LME cash zinc closed at $4,107/t on 27 August, up 55% from mid‑2025’s ~$2,650/t trough.
- Warehouse drawdown has pushed available LME metal to the lowest level recorded since April 2023.
- Physical tightness is evidenced by concurrent cash price escalation and declining on‑warrant LME inventory availability.
- Tightness is geographically skewed, with constraints mainly in Western LME warehouses rather than across all storage locations.
- Shanghai Futures Exchange zinc stocks have increased over the same period, indicating regional imbalance in metal distribution.
- HSBC attributes its 2026 mine output downgrade primarily to reduced zinc production in Latin America.
- JP Morgan, via Investing.com, anticipates sustained elevated zinc pricing through 2026 on tightening global supply and firm demand.
- Equity markets have re‑rated major zinc producers: Teck +47%, Glencore +46%, Nexa +60% since January 2026.
Our Take
Glencore and Teck Resources both feature repeatedly in our 2026 coverage of copper’s price surge, so their zinc‑linked equity gains here suggest diversified base‑metal portfolios are giving these majors a buffer against the volatility seen in gold‑heavy peers in the July MINING.COM TOP 50 review.
Zinc is one of only a handful of base metals that appears across the 43 keyword‑matched pieces in our database, and its current move now mirrors the earlier AI‑driven copper rally described in May 2026 coverage, signalling that project pipelines for both galvanising‑grade zinc and copper may be re‑evaluated using higher long‑term price decks.
