Zinc fell 0.39% to Rs 434.1/kg on MCX as high prices curbed Chinese demand and LME copper's tariff-driven pullback spilled over, even though mine-level zinc supply remains genuinely tight.
At a glance
- MCX zinc settled down 0.39% at Rs 434.1 per kilogram on September 23, pressured by high-price-driven demand destruction in China and expectations of more Chinese zinc flowing into LME warehouses.
- The drop came alongside a sharp LME copper pullback on shifting tariff expectations, which weighed on the wider base-metals complex.
- China's own zinc production contracted for the first time in nearly a year in August, down 1.8% year-on-year to 639,000 tonnes -- its weakest showing since May 2025 -- even though demand, not supply, is what's pressuring price today.
- Mine-level supply remains genuinely tight: Glencore's own-sourced zinc production fell 21% year-on-year in H1 2026, Boliden's concentrate output dropped 16.8% quarter-on-quarter, and an industrial accident at Korea Zinc's Onsan smelter has raised fresh supply concerns.
What happened
Zinc prices eased on September 23, 2026, with futures on India's Multi Commodity Exchange (MCX) settling down 0.39% at Rs 434.1 per kilogram, according to Kedia Advisory's daily commentary. The metal fell as elevated prices continued to discourage buying interest in China, the world's largest zinc consumer, and as markets priced in expectations of increased Chinese export deliveries into London Metal Exchange (LME) warehouses. The decline came even as a sharp pullback in LME copper, driven by shifting US tariff expectations, weighed on the broader base-metals complex. Open interest on MCX zinc fell 12.14% to 1,570 contracts alongside the Rs 1.7 price drop, a combination technical analysts read as long liquidation rather than fresh short-selling.
The details
Wednesday's dip looks, on the surface, like a simple demand story: zinc has gotten expensive enough that Chinese buyers, who account for roughly half of global zinc consumption, are stepping back, and that pullback is compounded by expectations that Chinese smelters will route more metal toward LME-registered warehouses rather than domestic buyers, adding to visible global supply. Kedia Advisory's commentary also points to a sharp pullback in LME copper, driven by shifting US tariff expectations, dragging the broader base-metals complex lower alongside zinc.
But the supply side of the zinc story doesn't actually support a straightforward bearish case. China's own zinc production contracted 1.8% year-on-year in August to 639,000 tonnes, the first such contraction in nearly a year and the weakest reading since May 2025. Outside China, the picture is tighter still: Glencore's own-sourced zinc output fell 21% year-on-year in the first half of 2026, Boliden's zinc-concentrate production dropped 16.8% quarter-on-quarter, and an industrial accident at Korea Zinc's Onsan smelter has raised fresh questions about near-term refined output. The LME's cash-to-three-month premium of $124 a tonne, a state of backwardation where near-term metal costs more than metal for later delivery, is itself a classic signal of tight physical supply rather than a glut.
That tension is the real story: demand is being rationed by price faster than supply constraints are easing, at least for now, which is why the market can show both a falling MCX price and a genuinely tight physical LME market at the same time. Technically, MCX zinc's Rs 1.7 fall came with open interest down 12.14% to 1,570 contracts, a combination that points to existing long positions being closed out rather than fresh bearish bets being placed. Support sits at Rs 431.9, with a break lower opening the door to Rs 429.6, while a recovery above Rs 437.3 resistance would target Rs 440.4.
Why it matters
Zinc is a bellwether for construction and automotive activity because of its dominant use in galvanizing steel, so a price pullback driven by demand rationing rather than a supply glut is a different signal for industrial buyers than a straightforward price correction would be -- it suggests the underlying tightness could reassert itself quickly once Chinese buying interest returns.
Our read
Outlook: bearish. Demand destruction in China and spillover from a tariff-driven copper pullback are outweighing genuinely tight mine-level supply for now; the LME's continued backwardation suggests this weakness may prove more fragile than a straightforward supply-demand rebalancing.
What to watch
- Whether Chinese buying interest returns as prices ease, or whether demand rationing continues at current levels.
- The pace of Chinese zinc export deliveries into LME warehouses relative to the market's earlier expectations.
- Any update on the Korea Zinc Onsan smelter incident and its impact on refined output.
- MCX zinc's Rs 431.9 support level; a break below opens the door to Rs 429.6, while a recovery above Rs 437.3 targets Rs 440.4.

Detailed analysis
Timeline
- 2026-08-01: China's zinc production contracts 1.8% year-on-year to 639,000 tonnes, its first contraction in nearly a year.
- 2026-09-23: MCX zinc settles down 0.39% at Rs 434.1 per kilogram as high prices curb Chinese demand and LME copper's tariff-driven pullback spills over.
Demand Drivers
Elevated prices have discouraged fresh buying in China, the largest zinc-consuming market, with the pullback compounded by expectations that Chinese smelters will direct more metal toward LME-registered warehouses rather than domestic sale.
Supply Drivers
Mine-level supply remains constrained: Glencore's own-sourced zinc production fell 21% year-on-year in H1 2026, Boliden's concentrate output dropped 16.8% quarter-on-quarter, and an industrial accident at Korea Zinc's Onsan smelter has added fresh supply uncertainty, even as China's own zinc production also contracted 1.8% year-on-year in August.
Inventory Drivers
Shanghai Futures Exchange zinc inventories rose 0.6% from the prior Friday, a modest build, while the LME's cash-to-three-month premium of $124 a tonne signals continued backwardation and tight near-term physical availability on that exchange.
Trade Tariffs
A sharp pullback in LME copper, triggered by shifting US tariff expectations, spilled over into the broader base-metals complex and added to pressure on zinc even though the tariff shift itself was not zinc-specific.
What could lift prices
- Mine-level supply is genuinely tight: Glencore, Boliden and Korea Zinc have all reported production setbacks in 2026, and China's own output contracted in August.
- The LME's $124-a-tonne cash premium over three-month zinc shows continued backwardation, a classic sign that physical buyers are still competing for near-term metal despite the softer futures price.
What could weigh on prices
- Elevated prices are actively rationing demand in China, the market's largest buyer, and that pullback shows no immediate sign of reversing.
- Expectations of increased Chinese export deliveries into LME warehouses would add to visible global inventory just as demand softens.
- A sharp LME copper pullback on shifting tariff expectations dragged the wider base-metals complex, including zinc, lower alongside it.
Country impact
| Country | Impact | Reason |
|---|---|---|
| China | High | China is the world's largest zinc consumer, and its demand pullback at current price levels is the primary driver of today's move. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Construction | Positive | Cheaper zinc lowers galvanizing costs for steel used in construction, zinc's largest end-use. |
| Steel | Positive | Zinc is the primary metal used to galvanize steel against corrosion, so a pullback in zinc costs eases input costs for galvanized-steel producers. |
Who gains, who loses
- Galvanized-steel producers and construction buyers: A softer zinc price lowers input costs for galvanizing, zinc's single largest end-use.
- Zinc miners and smelters already coping with lower output: Glencore, Boliden and Korea Zinc are all managing production setbacks in 2026, and a softer price adds pressure just as their own output is already constrained.
Other ways this could play out
- If Chinese buyers return once prices ease further, the underlying mine-supply tightness could reassert itself quickly and push zinc back toward resistance.
- A resolution of the tariff uncertainty currently pressuring LME copper could remove one of the drags on the broader base-metals complex, zinc included.
- Further supply setbacks, such as an extended outage at Korea Zinc's Onsan smelter, could tighten the physical market enough to overwhelm the current demand-led weakness.
Price risks
- A deeper-than-expected China demand pullback could extend the decline beyond the current support levels.
- A resurgence of mine-supply disruptions, from Korea Zinc's smelter incident or elsewhere, could sharply reverse the move given how tight the physical market already is.
- Continued spillover from LME copper's tariff-driven pullback could keep pressuring zinc independent of its own fundamentals.
Historical comparison
- H1 2026 vs H1 2025: The global refined zinc market ran a 120,000-tonne surplus in the first half of 2026, up from a 74,000-tonne surplus in the same period of 2025, even as June alone posted a 31,400-tonne deficit -- a reminder that the annual balance and the month-to-month picture can point in different directions.
