Zinc prices are sliding. China's the reason why.

By Siam Sukkhee Trading Co., Ltd — 2026-07-13 — zinc ingot supply demand

I watched zinc drop 0.7% in the US last week. China saw 0.9%.

That's what happens when you have 250,000 tons of zinc just sitting around doing nothing.

The story here is straightforward, more or less. Shanghai's Bonded Zone inventory is climbing because traders are betting the import window reopens soon. They're stacking metal in anticipation. Meanwhile, anyone actually trying to use zinc — the construction firms, the infrastructure people — they're not showing up like they used to. You push more supply into a market where nobody's buying, and the price goes one direction.

China's oversupply problem isn't temporary.

This year, smelter production is tracking up something like 300,000 metric tons year-on-year. That's more than 4% growth. Consumption is growing at maybe 1 or 2 percent, if we're generous. As far as I can tell, the gap just keeps widening. Shanghai Metals Market's numbers show domestic social inventory was already at 250,000 tons back in April, and the smelters haven't eased off the throttle since.

The core issue is China's property sector, which hasn't recovered like anyone thought it might. Developers are in cash-management mode, not building mode. Galvanized steel — which is where zinc goes — depends on construction. No construction, no pull. Infrastructure spending is happening, sure, but it's AI data centers and server farms. Zinc doesn't really feature there. Actually, that's not quite right — there's some use in supporting infrastructure, but it's marginal compared to what the property sector used to take.

Then MMG shut its Dugald River mine in Queensland for maintenance.

A year ago, a mine closure might have tightened things. Not now. Chinese smelters have enough zinc concentrate coming in to keep running without breaking stride. Finished ingot inventory has nowhere to go. The mine shutdown complicates the medium-term picture, but it doesn't solve the short-term problem of too much metal.

The real split is between China and everywhere else

What nobody's really talking about is how different the market looks if you're outside China. European smelters have been running at reduced capacity for years because energy costs are brutal there. New mine supply outside China hasn't picked up in any meaningful way. If you're a buyer in Europe or Southeast Asia or India, the market you're dealing with looks almost normal compared to what's happening in Shanghai.

That divergence matters more than people think.

Traders built the Bonded Zone stack because they thought they could move metal profitably when the import window reopened. When those windows close or tighten, the metal just sits. And when metal sits, spot prices follow it down. Which is what we're seeing. The arbitrage trade that looked clever a few months back now looks like a problem with no easy exit.

The structural case for zinc isn't dead, to be fair. Galvanizing is reliable. If construction in China actually kicked off again, the whole demand picture would shift. But that's not happening this quarter. Beijing's stimulus measures have been modest and narrow, not the broad infrastructure push that would move zinc at scale. Until something changes on that front, you're looking at oversupply, and the market's saying so with a 0.7% weekly slip.

The metal's going nowhere fast.
