The copper cathode market just vanished for a week

By Siam Sukkhee Trading Co., Ltd — 2026-06-29 — copper cathode trading Asia

The trading floors went quiet last week. Completely quiet. You know that feeling when everyone in your office suddenly has the same conference trip?

That's what happened to copper cathode trading across Shanghai and Southeast Asia in the week ending June 25. The London Metal Exchange's LME Asia Week in Hong Kong pulled virtually the entire market out of their seats, and what was left behind wasn't much—a few traders watching phones that weren't ringing, staring at prices that made no sense.

The real problem? The market was already broken before people left.

Fastmarkets put the benchmark copper grade A cathode premium CIF Shanghai at $(20)-0 per tonne. Let that number sit with you for a moment. The bottom of that range means you're not paying anything above the LME price to get cathode delivered to Shanghai. You're actually paying nothing. Or less than nothing if you squint at the range. That's not normal. That's barely a market at all.

Equivalent-grade cathodes delivered to Shanghai—the EQ premium—came in at $(60)-(50), which actually improved a bit from the week before at $(70)-(50), but "improved" is a relative term when you're talking about negative numbers.

Southeast Asia held up better, more or less.

The CIF Southeast Asia premium stayed at $50-65 per tonne, unchanged from the week before. Solid. Stable. Which tells you something interesting—either Vietnam, Indonesia and Thailand are still buying copper at reasonable volumes, or sellers have started routing around China altogether and accepting smaller orders elsewhere rather than eating deeper discounts in Shanghai. Probably both.

I spoke to a Shanghai-based trader who put it more bluntly than I could. "All traders are being hit badly," he said. "Prices are unprecedentedly at discounts, and demand in China stays weak." That word, unprecedentedly—he didn't throw it around casually. Copper cathodes have been discounted before, sure. But discounts this deep, held this long? That's new.

The traders sitting on inventory right now are the ones really feeling it.

Now, actually, that's not quite right. The ones really feeling it are the ones who imported cathode back when prices made sense, back when you could buy at better levels and expect to rotate stock. Those positions are underwater, and you can't shift them without taking a loss, which tends to make people very cautious about committing more capital.

LME Asia Week happens every year, and this year's version came loaded with conversations about something called de-fiatisation, re-globalisation, a potential new metals super-cycle driven by electrification, data center buildout, strategic government stockpiling. All of it makes copper sound essential. And it is, long term. Power grids, EV charging networks, data center cooling—the metal's involved in all of it, and demand for those things isn't going away.

But that doesn't help right now

None of that long-term thesis sits in bonded warehouses in Shanghai at negative premiums. China's downstream copper consumption—the cable makers, the fabricators, the people who actually turn refined metal into finished goods—has stayed sluggish through the first half of 2026. The property sector's weak. Manufacturing capex is cautious. Demand simply hasn't materialised the way people expected it to.

So when the traders reconvene after Hong Kong, nothing fundamental has shifted. The question is still the same. At what price does Chinese demand actually return? How long can people keep funding cathode they can't move at spot prices?

The LME conversations might shape positioning for the next five years. The discounts will shape this one.
