At the New York and London commodity exchanges, after months of upward rally in copper prices, a decline rates. Two weeks ago on November 11, on the LME, they reached a record level of $ 8966 / ton (an increase from the beginning of June for more than 45%). Now trading Friday November 18 8385 fixed price in $ / tonne. However, this figure is largely a reflection of speculative trends, not manufacturing needs. World prices for copper have fallen because of the rumors and fears that China is ready to take further measures to cool its overheated economy (this would lead to a damping of China's demand for raw materials in general, and the metal in particular). Nevertheless, the majority of medium-term forecasts are still talks about maintaining the upward price trend for copper.
