Copper and Zinc Hit Record Prices as Supply Splits

Key Takeaways: 

• Copper prices near record levels mask a split market: global exchange inventories look ample, but Chinese buyers face tight physical supply, driving the Yangshan import premium sharply higher.
• Zinc swung from a 27,500-tonne surplus in July to a 3,900-tonne deficit in August as London Metal Exchange stocks fell to their lowest level since March and cash contracts traded at an $81-per-tonne premium over three-month contracts.
• Tariffs, export controls and data center construction now shape copper and zinc pricing as much as traditional mine output, with Indonesian ore policy and Democratic Republic of Congo export rules doing the same for nickel and cobalt.

Copper and zinc traders have a new problem to solve, and it isn’t a shortage of metal. It’s a shortage of metal in the right place.

Prices for both metals sit near record or multi-week highs, and market participants at LME Week named copper the metal with the most upside potential. That optimism tells only part of the story. Dig into where the metal actually sits, and a more complicated picture emerges, one in which location, politics and new sources of demand matter as much as how much copper or zinc exists in the ground.

Why Does Copper Look Oversupplied and Undersupplied at the Same Time?

Global exchange inventories of copper appear healthy on paper. Warehouses in the United States have accumulated large volumes of metal, inflating the headline totals that traders watch. But headline totals hide regional strain.

In China, physical availability is still tight. The Yangshan premium, a measure of what Chinese buyers pay to import copper, has climbed sharply. Real competition exists for nearby supply, even as exchange data suggests comfort elsewhere. A pile of copper sitting in a US warehouse doesn’t help a factory in Shanghai that needs metal now.

This gap between where copper is counted and where it is needed has become the market’s defining feature. Traders can no longer rely on one global number to understand supply. They have to track where the metal physically sits, and that’s a much harder job.

How Are Tariffs and Trade Policy Reshaping Metals Markets?

Government decisions now move prices faster than new mines can. Indonesian decisions about ore supply shape nickel pricing. Export policy out of the Democratic Republic of Congo influences how much cobalt reaches global buyers. In both cases, a policy announcement can tighten or loosen supply faster than a mine expansion or a new processing plant ever could.

Meanwhile, copper producers face their own headwinds. Permitting timelines extend further each year. Capital costs keep rising. Environmental regulation adds complexity at every stage of development, and many existing mines are working with declining ore grades that make extraction more expensive and less efficient. New supply simply can’t arrive as quickly as the market wants.

What Does Data Center Growth Mean for Copper Demand?

Artificial intelligence infrastructure has added a new and urgent source of copper demand. Data centers require enormous amounts of power generation, transmission capacity and cabling, all of which depend on copper.

The mismatch is in the timing. A data center can be built in a fraction of the time it takes to permit, finance and construct a new copper mine. That gap forces investors and traders to ask a harder question than whether demand is rising. They need to know whether future production can keep pace with how quickly digital infrastructure is expanding. Right now, the honest answer is uncertain.

Why Is Zinc Suddenly Tightening?

Zinc has quietly become just as compelling a story as copper. London Metal Exchange zinc prices reached two-week highs as exchange stocks fell to their lowest level since March.

The shift shows up clearly in the data. The refined zinc market moved from a surplus of 27,500 tonnes in July to a deficit of 3,900 tonnes in August, reflecting both falling supply and constant demand. High electricity prices are squeezing smelter margins, since zinc processing needs considerable energy and expensive power makes production less profitable. Declining output in Peru adds further supply pressure.

The clearest signal of near-term scarcity is in the contract structure itself. Cash zinc has traded at roughly an $81-per-tonne premium over three-month contracts, a pattern known as backwardation. When buyers pay more for metal today than for metal delivered later, it usually means they need it now and can’t wait.

What Should Businesses Watch Next?

Headline inventory figures no longer tell the full story, so regional stock levels and import premiums deserve closer attention than global totals. A buildup in one warehouse can mask a shortage developing elsewhere.

Tariff announcements and sudden mine disruptions might move prices faster than any production change, so policy headlines deserve the same scrutiny as production reports. It’s also worth separating long-term structural demand, driven by electrification and data center growth, from short-term price swings that come and go with each new data release.

Supply forecasts deserve particular skepticism. New mining projects routinely face delays, and existing operations frequently contend with declining ore grades that limit how much they can realistically produce. A promising forecast for 2027 doesn’t solve a shortage happening today.
