Copper

Copper is the most important industrial metal. It conducts electricity and heat efficiently, resists corrosion and is easy to shape, so it is used in wiring, plumbing, motors, electronics and power grids. Because copper is used across construction and manufacturing, its price is often treated as a barometer of global economic health, earning the nickname "Dr Copper". The energy transition, with electric vehicles, renewables and grid upgrades, has added a powerful long term demand story.

How copper is traded#

COMEX prices are in dollars per pound; LME prices are in dollars per tonne. One tonne is about 2,204.6 pounds, so $4.00 per pound is roughly $8,800 per tonne.

Demand#

China consumes roughly half of global refined copper, so Chinese property, infrastructure and manufacturing data strongly influence prices. Electric vehicles use several times more copper than conventional cars, and grid and renewable projects are copper intensive, which many analysts expect to support demand for years.

Supply#

• Major producers: Chile, Peru, Democratic Republic of Congo, China and the US.
• Long lead times: new mines can take 10 to 20 years from discovery to production.
• Declining ore grades at many large mines raise costs.
• Disruptions: strikes, political changes, water shortages and accidents regularly cut supply. In 2023, Panama ordered the closure of the large Cobre Panama mine after protests, removing a notable share of global supply.
• Smelting and refining: concentrate must be processed; treatment charges signal how tight the concentrate market is.

Copper as an economic indicator#

Some strategists watch the ratio of copper to gold prices alongside bond yields, since copper reflects growth and gold reflects safety. See Gold.

Inventories#

Copper stocks are tracked in LME, COMEX and Shanghai warehouses. Low visible inventories can cause backwardation and price spikes, especially in the LME's nearby spreads. Large shifts of metal between exchanges, such as moves into COMEX ahead of possible US tariffs, can distort regional prices. See Storage and Inventories.

What drives copper prices#

Risks#

• Recession risk: copper can fall sharply when growth slows, as in 2008 when it fell by more than 60%.
• China specific risks in property and policy.
• Exchange specific events, including squeezes and regional price gaps.
