Copper Smashes Through $14,000 on LME as AI Data Centers and Iran War Supply Chaos Drive Metal Toward All-Time High

The New Number: $14,021

Copper closed at $14,021 per metric ton on the London Metal Exchange on Tuesday, according to CNBC. That's a record. The previous LME closing record was $13,618, set January 29, 2026, according to Discovery Alert.

On COMEX, July-dated futures settled at $6.531 per pound — also a back-to-back record close. The all-time intraday COMEX high is $6.61/lb. Tuesday's close sits roughly 2% below that record.

Year-to-date, copper is up 14.9% on COMEX. Since the Iran war started, it's added 7.8% alone, per CNBC.

What Changed This Week: Citi Goes All-In

Citi strategist Charlie Massy-Collier flipped his stance. In a Monday note to clients, he said the metal's break above the $13,500 resistance level — which had been a ceiling for weeks — confirms the structural demand story is real.

"We had been apprehensive about buying copper in recent weeks," Massy-Collier wrote. "Our interpretation of the recent break above $13,500 is one of the market confirming the strength of both the structural and cyclical demand setup, giving us conviction to chase the move higher."

His bull-case target: $15,000 per metric ton. He's backing it with a COMEX digital call option at $15,250, expiring August 5.

Three Things Driving This — None of Them Are Going Away

First: AI is eating copper. Massy-Collier told clients that "practically all copper demand growth since 2022 has come from energy transition and AI-related sources." Data centers require massive amounts of copper wiring, cooling infrastructure, and power distribution equipment. Every new GPU cluster is a copper order.

Second: The Grasberg mine is a disaster. PT Freeport Indonesia slashed its 2026 copper production target from 1 billion pounds to 700 million pounds, according to NDTV Profit. A deadly mudslide in September 2025 halted extraction at Grasberg — one of the world's largest copper mines. Full-scale operations aren't expected back until early 2028. The mine won't return to normal production for three years.

Third: The Iran war is choking sulfuric acid supply. Copper producers using oxide ore — roughly 20% of global output — depend on sulfuric acid to extract the metal. Sulfur shipments through the Strait of Hormuz have been disrupted by the war. Major African producers in the Democratic Republic of Congo and Zambia are already feeling it. Chile is also getting squeezed by Chinese export restrictions on the chemical, according to NDTV Profit.

The Iran war isn't just a geopolitical headline. It's physically constricting copper supply.

What the Coverage Is Getting Wrong

Most financial media is treating this as an AI hype story. CNBC's framing leans heavily on the data center demand angle, which is real but incomplete.

The supply-side collapse — Grasberg, Hormuz, sulfuric acid shortages across Africa — is getting buried. Supply disruptions are the more durable price driver. Demand can fluctuate. You can't replace 300 million pounds of annual production from a mine that won't be fully operational until 2028.

Also underreported: copper is NOT moving alone. According to Discovery Alert, the LME's combined base metals price gauge hit an all-time high the week of May 11. Zinc, aluminum, and nickel all posted meaningful gains alongside copper. When the entire complex moves together, it signals real physical demand rather than speculation alone.

The Strategic Stockpiling Factor

Massy-Collier flagged one more driver that hasn't gotten enough attention: strategic inventory stockpiling. Countries and corporations are building copper reserves as a hedge against future supply disruptions. Every ton stockpiled is a ton removed from available supply.

War disrupts supply. Governments stockpile in response. Stockpiling tightens supply further. Prices rise. The cycle repeats.

What This Means for Regular Americans

Higher copper prices are NOT abstract. Copper is in your house wiring, your car, your air conditioner, your power grid. When copper costs more, construction costs more, EVs cost more, grid upgrades cost more.

The energy transition the federal government has been spending billions to accelerate runs on copper. Every dollar of new solar, wind, or EV infrastructure requires copper at prices that just hit a record.

Taxpayers funding infrastructure bills signed in recent years are going to face real commodity math. The contracts were written before $14,000 copper. Bills will reflect $14,000+ copper.

Citi thinks $15,000 is coming. The mines can't keep up. The war isn't ending tomorrow. The AI buildout is accelerating.
