Zinc presents the most extreme dislocation in the base metals complex: a physical market so tight that LME on-warrant inventories cover less than a single day of global consumption, paired with a consensus forecast of a large refined surplus in 2026. LME 3-month zinc is trading around $3,500 per tonne, according to MetalCharts, recovering from sub-$2,500/t levels in 2024 on a deepening mine-supply deficit and a collapse in smelter treatment charges. Spot quotes touched $3,430/t in April, the highest in years, and the physical market remains gripped by what Reuters described as 'bears sleep-walking into a squeeze.'
The inventory numbers are startling. LME zinc stocks fell from 230,325 tonnes on January 2, 2025 to roughly 35,000 tonnes by late 2025 — an 85% drawdown — with only about 24,850 tonnes of on-warrant metal immediately available for pickup, per SMM data. Outflows are concentrated in Singapore warehouses, feeding real-world demand in Europe and ex-Asia as Western smelters cut output or close entirely. Toho Zinc's Annaka smelter in Japan and Glencore's secondary zinc operations in Italy have shut down. European smelters continue to operate at reduced rates due to high power costs lingering from the energy crisis.
The surplus paradox is explained by China. While the rest of the world is short refined zinc, China has significant surplus production. Chinese refined zinc output exceeds domestic demand, and exports have risen to multi-year highs. But slim margins and logistical bottlenecks are limiting how quickly this metal can rebalance the global market. Fastmarkets notes that 'Chinese exports hit a three-year high in October, but the rebalancing is slow.' The concentrate market in China is extremely tight, with treatment charges (TCs) at historic lows, forcing smelters to consider production cuts to protect margins even as refined metal piles up in domestic warehouses.
The ILZSG's 271,000-tonne surplus forecast for 2026 is built on a mine-supply rebound after three years of declines. Global zinc mine production contracted from 2022 through 2024, with European suspensions at Tara (Ireland) and Aljustrel (Portugal) cutting regional supply. But mine output is now recovering, particularly in China, where zinc ore availability rose 45% year-over-year in January–July 2025 versus a 22% decline in the same period of 2024, per StoneX data. Treatment charges are expected to lift from the record low of $80/t toward $160/t in 2026 as concentrate availability improves.
Analyst price forecasts capture the tension between short-term physical tightness and medium-term surplus. Fastmarkets' December outlook sees the 2025 average of $3,218/t carrying slight upward momentum into H1 2026 as regional disparities persist, but expects prices to soften as global surpluses build through 2026–2027. Morgan Stanley revised its 2026 zinc forecast to $2,900/t in December 2025, citing expectations that LME inventories would recover as China exports more zinc. At the bullish end, Goldman Sachs, Citi, and Macquarie — cited by Sook Trading — see $3,200–3,600/t for 2026, with upside risk to $4,000/t if LME stocks fall to 'critical' levels.
The smelter economics are under strain on both sides of the trade. Western smelters face high energy costs and constrained concentrate availability, leading to closures and run-rate reductions that have drained LME warehouses. Chinese smelters face the opposite problem: abundant concentrate becoming available as mines restart, but refining margins squeezed by historic-low TCs. Fastmarkets reports that 'for TCs to begin normalizing in 2026, exchange prices may be forced higher' — a self-reinforcing dynamic where smelter pain maintains supply tightness, supporting the very prices that should eventually incentivize more production.
Demand growth is flat to modest. Galvanized steel — zinc's primary end use, accounting for roughly 60% of consumption — faces headwinds from weak construction activity, particularly in China's property sector. The energy transition offers some offset (wind turbines, solar farm structures, EV bodies all use galvanized steel), but not enough to absorb the mine-supply growth that is now materializing. INN's 2026 zinc forecast describes 'another surplus in 2025, with an even larger overhang projected in 2026, despite LME stockpiles falling to just 33,825 tonnes.' That is the contradiction in a single sentence.
Zinc procurement in July 2026 requires navigating a market that looks tight on the screen but is fundamentally loosening beneath the surface. The playbook: First, do not chase the LME squeeze. LME stocks at 35,000 tonnes create headline risk and time-spread volatility, but the underlying flow of metal from China to LME warehouses is building. Paying up for spot metal now locks in prices at levels that the forward curve and analyst consensus suggest will soften through H2 2026 and into 2027. Second, structure contracts to benefit from the contango that should develop as Chinese exports rebuild LME stocks. If your contracts allow, use a floating-index formula with a lagged reference period (e.g., the month prior to shipment) rather than prompt-month pricing. Third, regional sourcing matters more than usual. European buyers are short physical metal because Western smelters are closing; Chinese buyers are long. If your supply chain can accommodate it, diversifying toward Asian-origin metal — even with freight and logistics costs — may provide better availability and pricing than competing for dwindling European LME warrant material. Fourth, monitor treatment charges as a leading indicator. When spot TCs rise from the current historic lows toward $160/t, it signals that concentrate is flowing and the refined surplus is becoming real — a sell signal for forward coverage. Fifth, for galvanized steel buyers: zinc is the primary input cost after steel substrate. The zinc price component of galvanized steel contracts should be unbundled and negotiated separately from the steel substrate, with an explicit zinc-index reference rather than an all-in price. This gives you transparency and the ability to hedge zinc exposure independently. Scenario probabilities: base case (55%) — Chinese exports gradually rebuild LME stocks, zinc averages $2,800–3,200/t in H2 2026; bull case (25%) — further Western smelter closures or a supply disruption keep zinc above $3,400/t; bear case (20%) — mine supply accelerates faster than expected, LME stocks recover to 100,000t+, zinc drops to $2,500–2,800/t.
