 The meteoric rise in the price of copper will likely continue thanks to a growing supply deficit that could reach 10 million metric tons — 25% of projected demand — by 2040, according to a new forecast from S&P Global. Copper is critical for everything from phones and refrigerators to EV batteries, AI data centers, and battlefield drones. Yet new mines are still incredibly slow and expensive to open, and existing ones are becoming more costly to operate as the quality of ore declines. The market is already undersupplied, and in 2025 several of the world’s largest mines were temporarily closed because of disasters including mudslides, earthquakes, and collapsed tunnels. Copper prices reached a fresh record Tuesday of $6.06 per pound. Without policy changes to accelerate the development of new mines, increase recycling, and, most importantly, to forge new trade deals between suppliers, processors, and users, copper shortages will become a major constraint on the AI revolution and the energy transition, S&P Global Vice-Chair Daniel Yergin told Semafor. “The world is electrifying, and copper can be either the enabler or the obstacle.” |
