Copper Price Surge Hides $400 Billion Supply Problem

Copper prices have reached an all-time high of $14,533 per metric ton on the London Metal Exchange benchmark three-month futures price, a 17% increase over the past year. The rally has both short-term and long-term drivers.

The looming U.S. tariffs on refined imports distort copper prices in the short term, while the deep-seated mismatch between constrained supply and long-term electrification demand drives the price up in the long term.

The main issue lies underground: operational issues at the world's largest mines are meeting accelerated consumption from the ongoing technology transition, driving a multi-year structural deficit. Global copper mine production declined 1.1% in the first half of the year, according to the International Copper Study Group.

Chile, which accounts for roughly a quarter of global mined output, has been at the center of the disappointment. The country posted its weakest second-quarter production in at least 19 years as severe winter storms, port closures and declining ore grades hampered operations.
