The global copper market supply deficit is only getting worse. Electrification, grid upgrades, and power-hungry AI data centers are converging on demand, threatening to stall the largest technological boom of the century.
Prices already show the strain. London copper hit an all-time high near $14,850 a ton in August and now trades around $14,470, up about 15% this year, according to Prinsights Global.
Refined metal "has grown scarce outside the United States" as traders ship physical copper into the U.S. ahead of expected tariffs. That dynamic has drained deliverable inventories elsewhere, including in China.
Forecasters disagree on how big the supply gap will be, yet they agree it's coming. Morgan Stanley sees the market short about 600,000 tons this year, and J.P. Morgan expects a shortfall of about 330,000 tons. The International Copper Study Group, long cautious, has flipped its surplus forecast to a deficit.
The long-term outlook is worse. BloombergNEF says the world will be short 20 million metric tons of copper by 2050 unless miners invest about $332 billion in new supply. Even if that money is spent, the gap is likely to remain open until at least 2043, because a new mine takes an average of 17 years to develop.
"Electrified transport is the fastest-growing copper application," BNEF analysts wrote. They described data centers as "a drop in the ocean for copper demand."
