Why copper is called 'Dr. Copper,' how Chile's 27% global output creates supply concentration risk, why EVs need 4x more copper than combustion engines, and the supply crunch thesis that could make copper the bottleneck of the energy transition.

Copper is called 'Dr. Copper' because it has an uncanny ability to diagnose global economic health. Unlike gold (safe-haven store of value), copper is embedded in industrial activity — infrastructure, electronics, power generation, manufacturing. Changes in copper demand historically precede wider macroeconomic shifts.
Chile: ~27% of global mine output. Peru: ~10%. Together, the Andean copper belt supplies nearly 40% of world supply. Corporate leaders: Codelco (Chilean state-owned, world's largest copper producer, El Teniente and Chuquicamata mines) and Freeport-McMoRan (NYSE: FCX). Declining ore grades and water scarcity in the Atacama are raising production costs.
Electric vehicles need ~83 kg (183 lbs) of copper per vehicle — roughly 4x the 20 kg in a traditional ICE vehicle. Renewable energy infrastructure is 5x more copper-intensive than fossil fuel plants. EV charging station rollout adds further demand. Analysts project global copper demand could double by the mid-2030s, far outstripping current supply.
Copper as economic indicator: when China's industrial activity accelerates, copper prices rise months before GDP data confirms it. When the BDI falls (see Baltic Dry Index), copper often follows. See also Lithium and Cobalt.
