Zinc prices have traded in a $3,300-3,540/t range through late Q2 2026, with LME three-month metal hovering near the top of that band as concentrate tightness increasingly threatens refined production. The Morgan Stanley 2026 average price forecast of $2,900/t has been consistently above spot for much of 2025 before spot overtook it, illustrating how analysts have systematically underestimated the supply-side constraints in this market.
The concentrate market is where the real stress resides. Treatment charges—the fee miners pay to smelters to convert concentrate into refined metal—are the most direct barometer of concentrate availability. When mines produce abundant concentrate, TCs rise as smelters have negotiating power. When concentrate is scarce, TCs fall. The fact that spot TCs have gone negative—to minus $50/t for Chinese imports as of June 2026—is unprecedented. It means the physical zinc concentrate market is tighter than at any point in modern market history, including the 2006-2007 super-cycle and the 2016-2018 supply crunch.
What makes this concentrate tightness particularly challenging is its persistence. The market has been talking about mine supply growth for over a year: new mines like Aripuanã in Brazil, Kipushi in the Democratic Republic of Congo, and the Ozernoye restart in Russia were all expected to ease the concentrate squeeze. Each has delivered some incremental tonnes, but not enough to offset disruptions elsewhere. The Antamina mine in Peru—one of the world's largest zinc producers—suffered a temporary shutdown in 2025 that removed approximately 2,000 tonnes per day of zinc concentrate from the market. Australia's Dugald River mine faced logistics disruptions from heavy rainfall. These events, while individually temporary, collectively prevented the expected concentrate surplus from materializing.
Chinese smelters are at the sharp end of the TC collapse. The China Zinc Smelter Purchase Team set Q2 2026 guidance for imported concentrate TCs at $35-70/dmt, down sharply from Q1 2026's $105-120/dmt range. At these levels, Chinese smelters are losing money on every tonne of zinc they produce from imported concentrate. Some smelters have begun to reduce operating rates, and the market is watching for more widespread curtailments. The CZSPT has discussed coordinated production cuts, though implementation has been uneven so far.
The refined zinc market balance flipped from expected surplus to deficit in the ILZSG's April 2026 update. ILZSG now forecasts a 19,000-tonne deficit in 2026, following a 33,000-tonne deficit in 2025. Refined production is expected to rise 1.4% to approximately 14.0 million tonnes, while demand rises 1% to 13.86 million tonnes. These numbers are small—zinc is a 14-million-tonne market—but the direction matters. A market that was expected to be comfortably supplied has become tight.
LME zinc inventories at 120,525 tonnes are substantially above the 2024 crisis lows when stocks fell below 40,000 tonnes, briefly reaching levels equivalent to less than one day of global consumption. The recovery in LME stocks has come primarily from trading house deliveries rather than a genuine loosening of the physical market. SHFE zinc stocks in China, in contrast, have remained ample, described by analysts as 'well above five-year averages.' The divergence between exchange stocks in China and the West reflects the concentrate flow: Chinese smelters with access to domestic and nearby concentrate sources are better supplied than their counterparts relying on seaborne imports.
Demand for zinc is heavily linked to galvanized steel production, which accounts for approximately 50% of global zinc consumption. Galvanizing demand has been supported by infrastructure spending in China and the U.S., as well as construction activity in India and Southeast Asia. However, the automotive sector—a significant zinc consumer through die-casting alloys—has shown mixed signals, with Chinese auto production strong but European and North American output flat to declining.
The forward catalyst for zinc is smelter behavior. If concentrate TCs remain negative for another quarter, significant smelter production cuts become inevitable. European smelters, which rely entirely on imported concentrate and face higher energy costs than their Chinese counterparts, are the most vulnerable. The Nyrstar and Glencore smelters in Europe have already operated at reduced rates through much of 2025-2026, and further cuts would tighten the refined market rapidly. The zinc market has a history of moving from apparent calm to acute tightness in a matter of weeks when smelters curtail—2022 provided a vivid example when European energy prices spiked and smelter cuts drove LME zinc to $4,500/t.
Zinc buyers should prepare for refined metal tightness in H2 2026 as the concentrate squeeze eventually forces smelter curtailments. The current situation—negative TCs, marginal smelter economics, and persistent concentrate tightness—is unsustainable. Something must give, and the most likely resolution is smelter production cuts that tighten the refined market and push prices higher. For procurement teams: prioritize securing Q3 and Q4 galvanizing-grade zinc volumes now, before smelter cuts are announced. Spot buying in this environment exposes you to both higher prices and potential delivery delays. Consider negotiating fixed-premium annual contracts with smelters or traders that include volume guarantees—premiums are likely to rise as the refined market tightens. For zinc die-casting alloys, the supply chain is shorter and more regional; monitor your local premium closely as an early warning signal. The key leading indicator to watch: LME canceled warrants for zinc. If canceled warrants rise above 20% of total stocks, it signals that metal is being pulled from warehouses for physical delivery and the squeeze has begun. Budget for zinc between $3,300-3,800/t through year-end, with upside risk toward $4,000/t if smelter cuts are significant.
