US Copper Supply Deficit Widens as AI Demand Surges and New Mines Lag

The United States faces a widening structural copper supply deficit that industry experts describe as difficult to solve quickly. The country produces less than half of the refined copper it consumes. According to the U.S. Geological Survey, America produced 850,000 metric tons of refined copper in 2025 while consuming 2.2 million metric tons, leaving a shortfall of more than 1 million metric tons that has to be covered by imports.

That reliance is not expected to ease. A June 2026 regulatory filing citing Wood Mackenzie data projects that the United States will remain a net importer through 2040, with imported refined copper accounting for roughly 70 percent of consumption. Globally, refined copper consumption climbed to 28.2 million metric tons in 2025 from 25.8 million in 2022, while production rose to 28.6 million from 25.2 million. The market that carried a modest surplus in recent years has now tipped into deficit. The International Copper Study Group revised its 2026 balance from a small surplus to a deficit of about 150,000 metric tons in May 2026, and several major banks forecast far larger gaps, with Morgan Stanley projecting a shortfall near 600,000 metric tons, the largest in more than two decades.

Demand is being driven by electrification, data centers, electric vehicles, and defense, with the artificial intelligence build-out adding a powerful new source of consumption. A January 2026 S&P Global study projected copper demand rising to 42 million metric tons by 2040 and warned of a shortfall of about 10 million metric tons without meaningful supply expansion. Prices have responded sharply. Copper futures settled at $6.20 per pound on June 28, 2026, nearly double the post-pandemic low of $3.23 per pound reached on July 11, 2022. On the London Metal Exchange, copper set a record above $11,700 per metric ton in December 2025 and traded above $13,000 in early 2026.

Veteran resource investor Rick Rule argues the shortage reflects three decades of underinvestment in exploration and development. He estimates that building a new mine can take around 18 years from discovery to production, which means no near-term action can prevent a supply crunch within five years. Few construction-ready projects exist, and in the United States permitting remains a major obstacle. On November 6, 2025 the Department of the Interior added copper to the USGS critical minerals list, a step intended to unlock federal incentives and faster permitting.

The Resolution Copper project near Superior, Arizona, illustrates both the promise and the delay. Jointly owned by Rio Tinto and BHP, the deposit was identified in 1995 and entered permitting in 2013, yet spent more than a decade in review. That logjam has recently broken. On March 13, 2026, a federal appeals court upheld a lower court decision denying an injunction sought to block the project, and on March 16, 2026, the U.S. Forest Service recorded the congressionally mandated land exchange and issued its final Record of Decision. Resolution Copper has since committed about $500 million over two years for early works and expects the mine, if fully developed, to supply up to a quarter of U.S. copper demand and add roughly $1 billion a year to Arizona's economy.

Development is far from guaranteed. The San Carlos Apache Tribe and allied groups continue to oppose the project over the loss of Oak Flat, a site of deep cultural and religious significance, and further state permits remain outstanding. Production is still years away even under the most favorable timeline. Meanwhile global supply has been squeezed by disruptions at major mines in Indonesia, the Democratic Republic of Congo, and Chile, and by the closure of the Strait of Hormuz, which lifted the cost of sulfuric acid used in copper processing. With new supply slow to arrive and demand accelerating, analysts expect elevated copper prices to persist.
