Copper prices are clearly on the defensive this morning are have fallen to a fresh 31/2 week low. In addition to fears of renewed slowing in China from slack Chinese trade data overnight, the copper market has also seen a rekindling of contagion fears toward the Greece debt crisis. News that China was seeing an increase in copper exports by smelters because of soft domestic demand may have added to the weaker tone of the market during overnight trading. Given the magnitude of the recent pullback, adverse currency market action and residual Greek debt fears, some traders feel that the copper market might not be able to relieve the current pressure on prices without several stronger than expected US economic numbers later on this morning.
