What Changed Since Our Last Report

When we last covered copper, the metal had smashed through $14,000 on the LME, driven by war-supply chaos and AI infrastructure demand. The story has shifted — but NOT in the direction bears were hoping for.

As of May 26, copper was holding near $13,680 a ton on the London Metal Exchange, according to Bloomberg. The LME was closed Monday for a public holiday, so Tuesday's open is the next real test.

That's a retreat from the January 29 spike that briefly carried prices above $14,500. The metal remains roughly 10% higher since the end of 2025.

The Iran Variable — Now Cutting Both Ways

The geopolitical driver is now a two-sided bet.

President Trump had previously rejected Iran's latest counterproposal as "totally unacceptable," per NBC News reporting. He called the April 8 ceasefire "unbelievably weak" and "on life support." Tehran's demands — full sovereignty over the Strait of Hormuz, war reparations, release of frozen assets, end of Washington's naval blockade — were dead on arrival in Washington.

But now, according to IndexBox citing Trading Economics, Trump stated the US is in the final stages of negotiations with Iran. That optimism is real enough to have triggered a 2% single-session copper gain earlier in the period, with futures touching $6.28 per pound on May 21.

The market is now trading on peace rumors after spending three months trading on war fears. Oil, which opened the conflict near $73 a barrel and hit $100 on Brent, dropped sharply on Hormuz-reopening hopes. Lower oil means lower inflation fears, which means less pressure on interest rates, which means industrial metals get a boost from improved growth expectations.

Whether the deal actually materializes is a different question entirely.

Supply Crunch: Still the Real Story

Mainstream coverage tends to lead with the Iran angle. It's dramatic, but OilPrice.com's Michael Kern put it plainly: "The market has moved on from the impact of the US-Iran conflict" as the primary price driver.

The actual supply pressures are significant:

Grasberg disruptions. The massive Indonesian mine operated by Freeport-McMoRan has been dealing with operational problems that have cut into output.

Chilean mining accidents. Chile is the world's largest copper producer. Accidents at Chilean operations have added to supply anxiety.

China's sulfuric acid export ban. Sulfuric acid is a byproduct of copper smelting. A Chinese export ban on it tightens the economics of global smelter operations — and China's smelters, including Jiangxi Copper and Yunnan Copper, are central to global refined copper supply.

Then there's Codelco — the Chilean state-owned giant and the world's largest copper producer — targeting roughly $2 billion in cost reductions and revenue gains by integrating operations across three mines, according to IndexBox. That's not an expansion plan. That's a company fighting stagnant production and rising debt. Codelco squeezing costs is NOT the same as Codelco producing more copper.

AI Demand Hasn't Cooled

The demand side of this equation remains intact. A rally in AI-related technology stocks — the kind of companies building data centers that require enormous amounts of copper wiring — continues to reinforce market expectations for sustained industrial demand, according to IndexBox.

Data centers are physical infrastructure. Every server rack, every power bus, every cooling system runs on copper. The AI buildout is a multi-year capital expenditure cycle. It doesn't pause because Iran and the US are talking.

What Mainstream Coverage Is Getting Wrong

Most outlets are framing this as a simple peace-deal story — copper goes up on war, copper comes down on peace.

The real dynamic is a decoupling. As OilPrice.com noted, copper is defying the traditional "war discount" applied to industrial metals. It's NOT just a geopolitical play anymore. It's a structural supply-deficit story with a geopolitical overlay that's now becoming a tailwind instead of a headwind.

If the Iran deal happens, oil drops, inflation eases, rate pressure lifts, and economic growth expectations improve. That's bullish for copper demand. The peace scenario isn't bearish for copper the way it's bearish for oil.

Aluminum and nickel also jumped — aluminum more than 2%, nickel 1.9% — when copper spiked, according to OilPrice.com. The LME's all-in metals gauge closed at a record on Friday. This is a broad industrial metals story, not just a copper headline.

What It Means for Regular People

Copper prices at these levels mean construction costs stay elevated. Wiring, plumbing, electrical equipment — all of it flows from the LME price. Homebuilders eat the cost first, then pass it to buyers.

If the Iran deal is real and sustained, some relief is possible. But the supply-side problems — Grasberg, Chile, Codelco's debt load — don't go away because diplomats shake hands in Geneva.

The LME reopens Tuesday. Watch the open. If copper holds above $13,500 without a war headline to prop it up, the structural bull case is confirmed.
