Copper just printed a fresh all-time high, and the story is no longer just about AI. The London Metal Exchange three-month copper contract settled at $13,943 per ton on Monday, breaking through the previous record close of $13,618 set on January 29 and posting its largest single-session gain in more than a month. COMEX copper futures pushed above $6.40 per pound, approaching the intraday peak of $6.61 set earlier in 2026. According to reporting from Bloomberg via Mining.com, the rally is being driven by a combination of structural demand and supply disruptions that are reinforcing each other in ways the market has not seen since the early 2000s commodity supercycle.

What is unusual about the current move is that it is happening despite the kind of geopolitical uncertainty that normally crushes industrial metals. The United States and Iran remain at an apparent deadlock over how to end the war and reopen the Strait of Hormuz, and President Trump just rejected Iran’s latest peace proposal as “totally unacceptable.” Equities have steadied. Oil has rolled over. Copper has decoupled from the conflict narrative and is now trading on its own fundamental story.

What Is Actually Pushing Copper Higher

The textbook explanation for copper’s run is the energy transition. Electric vehicles use about four times as much copper per unit as internal combustion vehicles. Renewable power systems and the grid upgrades required to deliver that power are copper intensive. Data centers and the hyperscale buildout for artificial intelligence have added a third structural demand pillar that did not exist five years ago.

But the marginal price action is now coming from the supply side. The Strait of Hormuz crisis has created a chokepoint problem for sulfuric acid, which is essential for copper refining. Roughly one-fifth of global copper production depends on acid leaching processes that consume more than one ton of sulfuric acid for every ton of copper produced. The Persian Gulf is one of the world’s largest sources of sulfur and sulfuric acid feedstock, and the closure of the Strait of Hormuz has disrupted those flows in a way that takes time to work through the supply chain.

Compounding the problem, China imposed a sulfuric acid export ban that runs from May through December and is removing roughly 3 million tons from the seaborne market. Chinese smelters are not selling acid to anyone outside the country, which means refiners in Africa, South America, and Asia that depend on imported acid are getting squeezed. That feeds back into refined copper availability and tightens the physical market further.

“The market has moved on from the impact of the US-Iran conflict, and copper has its own distinct price trend now,” Jia Zheng, a trading manager at Suzhou Chuangyuan Harmony-Win Capital Management, told Bloomberg. Her view is that tight supply and declining inventories in China are now the dominant drivers, not the geopolitical noise.

The Citi Forecast: $15,000 by Year End

Citigroup analysts have published one of the most aggressive forecasts on Wall Street, projecting copper could reach $15,000 per ton by the end of 2026. That would be roughly an 8 percent gain from current levels and a more than 20 percent increase from where copper started the year. The Citi case rests on three pillars.

First, the supply-side disruption from the Hormuz closure is structural, not transitory. Even if the strait reopens in the next few months, the acid supply chain takes quarters, not weeks, to rebuild. Smelters that have lost feedstock have to rebid for it on the world market against competing buyers, and Chinese supply is locked up until December at the earliest.

Second, the energy transition demand story remains intact. Global electric vehicle sales are still growing, and grid investment is accelerating in the United States, Europe, and India. The International Energy Agency projects copper demand will grow by roughly 50 percent over the next decade, and supply growth from new mines is structurally constrained because new copper projects typically take 10 to 15 years from discovery to first production.

Third, AI infrastructure is now a meaningful incremental demand driver. Hyperscale data centers require copper for power distribution, busbars, and cooling systems. The buildout that Big Tech is funding with hundreds of billions in capex translates into a measurable increase in copper consumption. Some analysts estimate that AI-related demand alone is adding 1 to 2 percent to annual global copper consumption growth, which sounds small until you remember that copper has been chronically undersupplied for several years.

Military demand is the fourth, less-discussed driver. Every Patriot battery, every THAAD interceptor, every missile-warning satellite, and every drone uses copper. The Pentagon’s $1.2 trillion Golden Dome program is just one example of the kind of multi-decade defense buildout that will keep copper bidding for years. Citi’s analysts have specifically called out “energy transition, AI, and military demand, along with supply constraints” as the four pillars supporting the bull case.

China’s Exports Are Telling a Different Story

One reason to take the bull case seriously is what is happening with Chinese exports. The country’s April headline export figure rose 14 percent from a year earlier, and clean-tech goods, which tend to be copper intensive, posted some of the strongest gains. Electric vehicles, solar panels, wind turbines, and batteries are all being shipped out of China at record rates. That means copper-containing finished goods are leaving the country even as China keeps acid feedstock home, which creates a double squeeze on the rest of the world’s copper inventories.

The dynamic has not gone unnoticed at the major commodities conferences. Last week’s Asia Copper Week in Hong Kong featured almost uniformly bullish takes from traders and miners. Copper is now up about 12 percent from the end of 2025, after sharp dips in the opening weeks of the Iran war when investors feared a serious economic shock. Those fears have not materialized in the way the bears expected, and the structural demand picture has reasserted itself.

What This Means for Investors

The most direct way to play copper is through the major mining companies. Freeport-McMoRan (NYSE: FCX) is the largest U.S.-listed copper pure play and has been one of the strongest performers in the S&P 500 this year. Its Grasberg operation in Indonesia is recovering from the supply disruption that hit the stock last year, and the company stood by its 2027 production forecast on Monday. Southern Copper (NYSE: SCCO) and Antofagasta (LSE: ANTO) are the two largest non-U.S. integrated producers. BHP, Rio Tinto, and Glencore all have major copper exposure inside diversified portfolios.

The Global X Copper Miners ETF (NYSE: COPX) and the iShares Copper and Metals Mining ETF (NYSE: ICOP) provide diversified exposure. The Sprott Physical Copper Trust is the closest thing to a physical copper investment vehicle, though it is structured differently from the gold and silver versions.

For investors who prefer to play the AI demand angle without the commodity volatility, the picks-and-shovels approach is to buy the companies that make the copper-intensive products. Cable manufacturers, transformer producers, and grid infrastructure firms are all riding the same demand wave. Encore Wire and Atkore are pure-play U.S. names that have benefited from data center and grid spending.

It is also worth noting that copper is now competing with gold and silver for investor attention in a way it has not in years. Precious metals have rallied on safe-haven demand from the Iran war, but copper is rallying on industrial demand. The 7k Metals direct retail platform and other physical metals dealers report increased interest in copper bullion alongside the traditional silver and gold lines. Copper does not have the monetary premium of precious metals, but as an industrial investment, the structural case has rarely been stronger.

The Risks to the Bull Case

The bear case for copper is mainly cyclical. A sharper-than-expected Chinese property slowdown, a global recession, or a major demand shock from a U.S. economy that finally rolls over could all pull copper back. The Chinese real estate crisis has been a persistent overhang on industrial metals demand for years. Chinese property construction accounts for a meaningful share of global copper consumption, and a sharper downturn there would offset some of the structural demand growth from EVs and AI.

There is also a regulatory wildcard playing out inside China right now. A regulatory crackdown on metals-backed financing has triggered turmoil for some Chinese trading companies, and that has limited scrap copper supply in unusual ways. The discount between scrap and refined copper has narrowed, which is technically supportive of refined prices but also creates volatility that traders are still working through.

The Hormuz situation could also de-escalate faster than the market currently expects. If the strait reopens and acid supply normalizes, the copper-specific supply premium would come out of the price. Citi’s $15,000 target assumes the supply disruption persists for several quarters, which is the most likely scenario but not the only one.

The Bigger Picture for Commodities

Copper’s record run is part of a broader story about industrial metals that the market has been slow to fully appreciate. Aluminum is also rallying because the Strait of Hormuz closure hits Gulf aluminum smelters that depend on the region for sulfur. Nickel is up because producers depend on the same supply chains. The LME’s combined gauge of base metals prices ended Friday at an all-time high. This is not just a copper story. It is a commodities story driven by the convergence of structural demand growth, supply chain fragility, and geopolitical disruption.

For Israel-focused investors, the connection is worth noting. The same Iranian aggression that closed Hormuz, that drove the Israeli defense budget higher, and that pushed up oil prices is also the proximate cause of the copper rally. The geopolitical and commodity stories are intertwined. As long as Tehran continues to threaten the global energy and metals supply chains, the commodity bid is going to stay structural rather than cyclical.

The $13,943 close on Monday is a number traders will remember. Whether copper reaches Citi’s $15,000 target by year end depends on factors that no one can perfectly predict, but the structural setup is the most bullish it has been in two decades. The pieces are in place for a sustained move higher.

Frequently Asked Questions

Why are copper prices at record highs in May 2026?

Copper hit record highs above $13,900 per ton on the LME because of a combination of structural demand from the energy transition, AI data center buildout, and military procurement, alongside acute supply disruptions from the Strait of Hormuz crisis and China’s sulfuric acid export ban that runs through December 2026.

How does the Strait of Hormuz affect copper supply?

The Persian Gulf is a major source of sulfur and sulfuric acid feedstock used in copper refining. Roughly one-fifth of global copper production depends on acid leaching processes that require more than one ton of sulfuric acid per ton of copper produced. The Strait of Hormuz closure has disrupted these acid flows in a way that takes quarters to rebuild.

What is Citi's copper price target for 2026?

Citigroup analysts project copper could reach $15,000 per ton by the end of 2026, which would be roughly 8 percent above current levels. The forecast rests on continued supply disruption, structural demand from the energy transition, AI infrastructure buildout, and military procurement.

How much copper does AI demand actually consume?

Hyperscale data centers require copper for power distribution, busbars, and cooling systems. Some analysts estimate that AI-related demand is adding 1 to 2 percent to annual global copper consumption growth. That sounds small, but copper has been chronically undersupplied for years, and incremental demand at the margin has an outsized effect on price.

Which stocks benefit most from rising copper prices?

Freeport-McMoRan (NYSE: FCX) is the largest U.S.-listed pure play. Southern Copper (NYSE: SCCO) and Antofagasta (LSE: ANTO) are the next largest. Diversified miners like BHP, Rio Tinto, and Glencore have major copper exposure. The Global X Copper Miners ETF (NYSE: COPX) provides diversified exposure to the sector.

What could pull copper prices back down?

The main bear risks are a sharper Chinese property slowdown, a global recession, or a faster-than-expected resolution of the Strait of Hormuz crisis that normalizes the acid supply chain. A Chinese regulatory crackdown on metals-backed financing has also created near-term volatility.
