How is Copper Priced?
The two main markets for copper are the London Metal Exchange in the UK and the New York Mercantile Exchange in the US. On the London Metal Exchange, copper is traded by 25-tonne lots, which are priced per tonne in US dollars. On Comex, which is a division on the New York Mercantile Exchange, it is traded by lots of 25, 000 pounds. It is priced in US cents per pound. When trading copper, things to look out for include any kind of social or political unrest in the country where it is mined – this can affect the levels of production.
