Copper is commonly traded on global commodity markets, and its price movements are often used as a barometer for the world economy.
Copper is widely used in the manufacturing of many everyday items, such as electric wiring, microwaves and home heating systems. lt follows that any increase in demand for copper is indicative of activity in the wider economy.
Copper is available in greater quantities in nature than gold, silver and platinum, so tends to be substantially cheaper. However, the mass industrialisation of the developing world has pushed the production of copper steadily higher in recent decades.
