Copper is trading at record prices, yet the companies that turn raw ore into usable metal cannot make money doing it. That paradox now defines the copper market, and it reveals more about who actually controls the world's most important industrial metal than any single price headline does.

Three-month copper on the London Metal Exchange hit an all-time high of $14,779 a ton on Tuesday — its fourth consecutive session of gains — before easing back toward $14,630 on Wednesday morning. The metal is up close to 18% this year. In the United States, COMEX copper is trading near $6.75 a pound, pulled higher by the same forces driving London.

None of those gains, however, are reaching smelter bottom lines. The 2026 benchmark treatment and refining charge — the fee miners pay smelters to turn concentrate into finished metal — settled at zero dollars a ton this year, the lowest annual benchmark on record. That is down from $21.25 in 2025 and $80 in 2024. Spot rates have fallen further still, dropping to roughly negative $127 a ton by midyear, meaning smelters are effectively paying miners for the right to process their ore.

Whoever Owns the Concentrate Is Winning

China smelts roughly half of the world's copper and has accounted for more than 90% of global smelting capacity growth since 2005, tightening its grip on the processing side of the business even as it squeezes its own margins. Beijing built that capacity on the assumption that mine supply would keep pace. It has not, and that gap is now the defining fact of the copper market.

"It's really hard to fix a number between miners and smelters, with both having strong arguments," one Shanghai trader involved in this year's negotiations told Fastmarkets, adding that miners currently hold the upper hand.

Mine supply, not processing capacity, is the actual constraint. Chile posted its weakest second-quarter output in at least 19 years, and Antofagasta's first-half production fell 9.5%. Congo's Kamoa-Kakula and Indonesia's Freeport operations both saw disruptions, while Panama's Cobre Panama mine remains shut amid an ongoing legal fight with the government.

More Smelters Are Coming Anyway

None of this is slowing new construction. Countries increasingly treat smelting capacity as a strategic asset rather than a margin business. Indonesia alone has pulled in more than $9 billion in copper smelter investment over the past few years, chasing the same downstream playbook that turned it into a nickel-processing power. Globally, projects on the table could add more than 8 million tons of new smelting capacity by the early 2040s, most of it in Asia. With more capacity chasing the same shrinking pool of concentrate, negative treatment charges look less like a blip and more like the new normal.

Tariffs Are Scrambling Trade Flows

Washington is adding another distortion. The prospect of a US tariff on refined copper imports has been pulling metal into the country ahead of any actual policy, tightening availability everywhere else. COMEX inventories have climbed to a record near 700,000 tons, while LME and Shanghai warehouses combined hold barely 300,000 tons between them. The shift is draining the rest of the world and layering a fresh premium on top of an already tight concentrate market.

That makes treatment charges, mine output, warehouse inventories, and the timing of any US tariff policy the key pressure points for the market. Together, they will show whether the current squeeze is being relieved by additional supply or merely redistributed between miners, smelters, and consuming regions.

Meanwhile, data centers, electric vehicle production, and grid buildouts tied to the energy transition keep adding load to a metal whose global mine output has grown at a fraction of its 1990s pace. That is the backdrop analysts point to when they describe a multi-year, rather than cyclical, supply gap — and it explains why buyers are not waiting for treatment charges to normalize before locking up supply.

None of this is really a Chile problem, a China problem, or a US problem on its own. It is a structural squeeze that starts at the mine, where new supply takes a decade or more to develop, and works its way through every stage of the chain: smelting, refining, and now trade flows warped by tariff politics. Record prices are the symptom. The real story is that the business of turning copper ore into usable metal is running at a loss almost everywhere, while control over the raw ore itself has become the only place left in the chain to make money.
