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

| Instrument | Details |
|---|---|
| COMEX copper futures (HG) | 25,000 pounds; $0.0005 per pound tick = $12.50 |
| Micro copper futures (MHG) | 2,500 pounds |
| LME copper | 25 tonnes per lot; quoted in dollars per tonne; global benchmark |
| Shanghai Futures Exchange copper | 5 tonnes per lot; quoted in yuan per tonne |
| Mining stocks and ETFs | Exposure through producers or futures based funds |

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

| Use | Approximate share of demand |
|---|---|
| Electrical networks and power | Largest share |
| Construction (wiring, plumbing) | Large share |
| Transport (including electric vehicles) | Growing |
| Industrial machinery and consumer products | Remainder |

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

**Example: Copper and growth signals**
In early 2020, copper fell from about $2.85 to $2.10 a pound as COVID lockdowns hit China and global industry. As China reopened and governments stimulated their economies, copper doubled to more than $4.50 by May 2021, a record at the time. Bond yields and stock markets also recovered over the same period, and analysts pointed to copper's rise as a signal of strong global recovery. See [Business and Economic Cycles](https://learn.tradelabsai.com/macro/business-and-economic-cycles/).

Some strategists watch the ratio of copper to gold prices alongside bond yields, since copper reflects growth and gold reflects safety. See [Gold](https://learn.tradelabsai.com/commodities/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](https://learn.tradelabsai.com/commodities/storage-and-inventories/).

## What drives copper prices

| Driver | Effect |
|---|---|
| Chinese economic activity | The largest single demand factor |
| Global manufacturing (PMIs) | Strong PMIs support copper. See [PMI](https://learn.tradelabsai.com/macro/pmi/) |
| US dollar | A weaker dollar tends to support copper |
| Supply disruptions | Strikes and mine closures lift prices |
| Energy transition policy | Long term demand expectations |
| Trade policy | Tariffs and export controls |

## 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.
