The copper market has moved lower this morning, with some traders feeling that prices have generally held up well in the face of sagging global macro economic sentiment. Extensive weakness in global equity markets, another credit downgrade of Greek sovereign debt and ongoing fears with the US debt ceiling debate are widely seen as negative factors for copper prices. The copper market may also be reflecting some concern with labor inspired production losses, but any threat to physical supply may likely be a secondary factor in this current market environment. Some traders feel that copper may have looked periodically towards China for support against negative economic sentiment from the US, but it is unclear whether expectations for strong demand from China may be capable of cushioning copper against any broad based physical commodity market liquidation wave. LME Copper Stocks were 471,200 tons, down 1,125 tons.
