COPPER & INDUSTRIAL METALS (HG, ALI)
Plain English
Copper is called 'Dr. Copper' because it has a PhD in economics — its price tends to predict global economic health. When copper rises, it signals industrial expansion; when it falls, it signals slowdown. Industrial metals futures (copper, aluminum, nickel, zinc) are driven by Chinese manufacturing demand, infrastructure spending, and the energy transition.
Going deeper
Copper futures (HG) on COMEX: 25,000 pounds, tick = $0.0005/lb = $12.50. Key drivers: Chinese demand (China consumes ~55% of global copper — Chinese PMI data moves copper prices significantly), Global construction and infrastructure spending, Energy transition demand (EVs use 4x more copper than ICE vehicles; solar panels, wind turbines, and grid upgrades all require massive copper inputs), Mine supply disruptions (large mines in Chile, Peru, DRC), LME warehouse stocks (London Metal Exchange inventory as a real-time supply indicator), and US dollar strength (commodities priced in USD). Aluminum (ALI): 44,000 lbs on COMEX, energy-intensive to produce (natural gas and electricity prices matter). The spread between LME and COMEX copper creates arbitrage opportunities (geographical basis risk). Goldman Sachs has called copper 'the new oil' for the energy transition decade — a key structural bullish thesis.
Examples
China PMI Signal
China's Caixin Manufacturing PMI prints at 51.8 vs. 49.5 expected — expansion territory. Copper futures immediately rally 2.5% on the open. The logic: strong Chinese manufacturing = more copper consumption for machinery, appliances, and construction. Copper traders watch Chinese data as a first-order driver.
EV Demand Thesis
A traditional gasoline vehicle uses roughly 18-22kg of copper. A battery electric vehicle uses 80-100kg. As EV adoption grows from 10% to 50% of new vehicle sales globally, the implied copper demand increase runs into the millions of metric tons. This structural demand story underpins many long-term bullish copper thesis.
