The ICSG flipped its 2026 copper book from a 209,000-ton surplus to a 150,000-ton deficit in one revision. Mine supply growth slid to 1.4 percent, refined output to 0.9. Freeport cut Grasberg's 2026 plan to 478,000 tons against a 700,000 baseline after the September mud rush killed seven and pushed the second-largest copper mine in the world into a force majeure that does not fully lift until 2027.

The thesis the sell-side ran from 2014 to 2024 priced copper as a cyclical commodity recovering inside the regular cap-ex cycle. Ore grades slid from 1 to 2 percent historically to under 0.7 today, and the average new mine takes 17 years from discovery to first production. The drill pad that nobody breaks ground on this year is the transmission line missing in 2040.

Copper crossed 12,000 dollars on the LME this quarter, up 42 percent on the year, and the desks still file it as a squeeze. Goldman is publishing a 525,000-ton shortfall across 2025 and 2026. Every gigawatt of AI data center, every battery factory, every electrified ton of cap-ex the abundance roadmap is signed against runs through the same red metal. The price is doing the work the calendar refused.
