Copper

Copper started May trading above $2.3 per pound, on signs that China’s manufacturing sector could be recovering faster than expected from the coronavirus pandemic slump as many factories there started to resume operations. Still, copper prices came under pressure on renewed tensions between the US and China after President Trump threatened to impose new tariffs on China over the coronavirus crisis. Historically, Copper reached an all time high of 4.63 in February of 2011. Copper futures are widely traded on the London Metal Exchange (LME), at the COMEX and on the Multi-Commodity Exchange in India. The standard contract is 25,000 lbs. Copper is the third most widely used metal in the world. Chile accounts for over one third of world's copper production followed by China, Peru, United States, Australia, Indonesia, Zambia, Canada and Poland. The biggest importers of copper are China, Japan, India, South Korea and Germany. Copper market prices displayed in Trading Economics are based on over-the-counter (OTC) and contract for difference (CFD) financial instruments. Our copper market prices are intended to provide you with a reference only, rather than as a basis for making trading decisions.
