Copper futures settled down on Wednesday as the US dollar held near a two-week high, which makes copper more expensive for buyers using other currencies. Copper prices weakened further on worries of worsening demand in China after Moody's slashed China's credit outlook to negative. Although, supply disruptions in the Cobre mine in Panama limited further falls in copper prices.
