Copper's international benchmarks are the futures prices on the London Metal Exchange (LME) and on COMEX, part of CME Group. The LME quotes copper in dollars per metric ton, COMEX in dollars per pound, and the Shanghai Futures Exchange provides an additional reference for Asian demand. Copper is the quintessential industrial metal, used in wiring, construction, electronics, and electric vehicles. China accounts for roughly half of global copper demand, giving its economy an outsized influence on the price.
Copper is nicknamed "Dr. Copper" for its reputation as a metal with a doctorate in economics, because its broad industrial use makes it a leading proxy for real economic activity. Rising copper prices are generally read as a sign of strengthening manufacturing and construction, while declines suggest softening industrial demand. This makes copper one of the most frequently cited gauges of the global business cycle. The copper-to-gold ratio is a common companion indicator, comparing growth expectations against safe-haven demand.
The main drivers are Chinese construction and infrastructure activity, global manufacturing conditions, and supply from major producers such as Chile and Peru. Electrification trends, including electric vehicles, renewable energy, and power-grid investment, are widely seen as structural supports for long-term demand. Because copper is priced in dollars, a stronger dollar tends to weigh on the price, and changes in LME warehouse inventories offer short-term supply clues. Global manufacturing PMIs, Chinese economic data, and the dollar index are the usual cross-checks.
