Copper Hits Record High, Faces $400 Billion Supply Gap

Copper prices hit an all-time high, with three-month benchmark futures on the London Metal Exchange climbing to $14,533 per metric ton.

Copper has risen about 17% over the past year, driven by both short-term and long-term factors. The short-term driver is market distortion caused by impending U.S. tariffs on refined copper imports, while the long-term driver is a deep-rooted mismatch between constrained supply and sustained electrification demand.

Although inventory flows and speculative positioning keep tariff headlines in focus, the core issue lies underground. Operational problems at the world's largest mines, combined with accelerating consumption from ongoing technological transition, are driving a multi-year structural shortage.

Aging Mines and Declining Output

According to the International Copper Study Group, global copper mine production fell 1.1% in the first half of this year, raising the prospect of the first annual supply contraction since 2017. Morgan Stanley had earlier expected output growth this year but now sees production remaining broadly flat or slightly lower.

Chile, accounting for roughly a quarter of global mine output, is at the heart of this output miss. The country's second-quarter production hit its weakest level in at least 19 years, hampered by severe winter storms, port closures, and declining ore grades. August exports plunged 14% from July to $4.62 billion, the lowest monthly figure in over a year—despite average prices running more than 40% higher year-over-year.

Major operators, including Codelco and Freeport-McMoRan, Inc., posted double-digit output declines due to accidents, weather events, and asset aging.

"This is a problem of declining grades at existing operations. This is old, very, very old assets. This is a problem of lack of new supply development coming into the market," said Evy Hambro, global head of thematic and industry investing at BlackRock, in a Bloomberg Television interview.

Friction is sharpest between mines and smelters. Smelting capacity continues to expand, particularly in Asia. This trend intensifies competition for scarce concentrate and pushes treatment charges toward zero or even negative.

Morgan Stanley expects refined copper production to grow by roughly 0.9% even if mine supply stays flat—masking the severity of upstream constraints.

Runaway Capital Expenditure

Structural project shortfalls compound the problem. Mining investment was slashed after the commodity downturn a decade ago, leaving a thin project pipeline, while lengthy permitting means significant new mine supply is unlikely before 2030.

In the meantime, capital expenditure pressure keeps building. A figure often cited by Rick Rule and other veteran investors is that maintaining existing output through 2035 alone would require $250 billion in 2025 dollars—a number that could climb above $400 billion by the 2030s.

That capital is needed merely to sustain already-strained existing production. The figure required to meet market demand is likely far higher. Under these conditions, a long-term price squeeze is all but certain, but even near-term expectations remain elevated.

Citigroup analyst Tom Mulqueen forecasts copper reaching $15,000 per ton by year-end, with potential upside to around $17,000 if manufacturing recovery or energy transition and data center demand prove stronger than expected.
