Copper prices have traded sharply lower this morning and have reached their lowest levels since late November. Asian copper prices were thought to be under pressure because of fresh Chinese slowing fears and renewed Euro zone fears. With the Chinese central bank indicating they planned to maintain a prudent monetary policy, many in the market expect to see even more economic slowing evidence ahead from one of the world's most important copper demand sources. With weaker equities, a stronger dollar and ideas that the Euro zone situation is destined to return to a level of anxiety again, recent news headlines are thought to be a key negative factor for the copper market.
