Live Zinc Prices and Inventory Data

The global zinc market has done something that commodity forecasters hate: it has refused to follow the script. In October 2025, the International Lead and Zinc Study Group (ILZSG) published a forecast calling for a 271,000-tonne global refined zinc surplus in 2026. Smelters were expected to ramp up production as concentrate supply — long the bottleneck — finally loosened. Instead, the first half of 2026 has delivered the opposite: concentrate treatment charges have fallen to historic lows of $30-50 per dry metric tonne, LME inventories have shrunk to 114,275 tonnes, and the physical market is trading at backwardation across prompt delivery dates.

The root cause of the disconnect is upstream. Global zinc mine production has underperformed expectations by roughly 4-5% in 2026, with key operations in Peru, Australia, and Ireland delivering less ore than planned. The zinc concentrate market — the raw material that feeds smelters — entered 2026 already tight after two years of underinvestment in new mine capacity, and the supply response that was supposed to arrive in H1 2026 simply has not. Teck Resources' Red Dog mine in Alaska, one of the world's largest zinc mines, shipped less concentrate in Q2 than in Q1 due to weather-related logistics disruptions. Glencore's Peruvian operations faced community-related downtime. Boliden's Tara mine in Ireland, which restarted in late 2025 after a 16-month care-and-maintenance period, is ramping up more slowly than expected.

The smelter side is equally stressed. South Korea's zinc smelting complex — the largest outside China — has faced production disruptions related to power costs and maintenance scheduling, tightening the Asian refined market. European smelters, which were forced to curtail output during the 2022-2023 energy crisis, have not fully returned. Nyrstar's Auby smelter in France remains offline, and Glencore's Nordenham smelter in Germany is operating well below capacity. Collectively, these disruptions have removed an estimated 150,000-200,000 tonnes of annual refined zinc production capacity from the Western market — roughly 1.5% of global supply — at the same time that mine production is falling short.

StoneX senior metals analyst Natalie Scott-Gray has characterized the current market as a "supply crunch exposing fragile links in global metal production." Her analysis points to a structural shift: zinc demand outside China — particularly in India, Southeast Asia, and the US — has grown faster than most models predicted, driven by infrastructure galvanizing and automotive manufacturing. Indian zinc consumption alone grew approximately 8% in the first half of 2026, absorbing metal that would previously have flowed into LME warehouses. The market's traditional buffer — excess Chinese production available for export — has been eroded by China's own demand growth and, critically, by Beijing's export tax policies that discourage raw material exports.

The ILZSG's surplus forecast deserves scrutiny. The 271,000-tonne figure assumed mine production growth of 3.2% in 2026 and negligible smelter disruptions. Both assumptions have proven wrong. Mine production is tracking closer to 0-1% growth, and smelter disruptions have cumulative impact of roughly 200,000 tonnes — enough to flip the model from surplus to deficit. When ILZSG publishes its mid-year update, the surplus forecast will almost certainly be revised sharply lower, and the market appears to be pricing that revision in advance.

The demand story is nuanced but net positive. Galvanized steel — which consumes roughly 50% of global zinc production — is seeing steady demand from infrastructure spending in the US (the Infrastructure Investment and Jobs Act continues to fund bridge and highway projects), India's National Infrastructure Pipeline, and Southeast Asian construction. The automotive sector, zinc's second-largest end-use, is consuming more zinc per vehicle as corrosion protection requirements tighten — average zinc coating weights on automotive body panels have increased approximately 15% over the past decade. Die-casting alloys and brass production provide stable baseload demand.

China's role in the zinc market has evolved. Chinese refined zinc production rose 9.4% year-on-year in May 2026, a figure that would normally suggest ample supply. But the increase reflects smelters running hard to capture high treatment charges on imported concentrate purchased under older contracts — a strategy that is unsustainable as spot TCs have collapsed. Chinese smelters that rely on spot concentrate purchases are already facing negative margins at current TC levels, and production cuts are expected in Q3. The Shanghai Futures Exchange (SHFE) zinc inventory has declined to approximately 35,000 tonnes, down from 60,000 in March, confirming that Chinese domestic supply is tightening.

The forward risk map for zinc is asymmetric to the upside. On the supply side: additional smelter curtailments are likely if power costs in Europe rise during the winter heating season. The Red Dog mine shipping season is constrained to roughly July-October by Arctic ice conditions — any weather disruption in that window removes a critical source of concentrate. On the demand side: China's Third Plenum could include new infrastructure spending that boosts galvanized steel demand. The bear case — a global recession that crushes industrial demand — would hit zinc hard, but with inventories already at critically low levels, the downside from current prices may be more limited than the upside if supply disruptions continue.
