Copper falls as dollar rallies

Copper prices fell on Thursday, as the US dollar rose against most major currencies.

Copper prices at London Metal Exchange fell 0.7% to $6,729 per tonne, but remain close to the 2-year high that was hit on September 1 at $6,830.

The US Federal Reserve on Wednesday projected the US economic growth to speed up compared to previous expectations, and signaled its plans to keep it near zero until the end of 2023.

The US-China trade tensions are still casting a shadow over the commodities and metals markets, but China's growing purchases lifted copper demand.
