SHANGHAI, Sept. 14 (SMM) –Shanghai spot copper offers were quoted between discounts of negative RMB 150-50/mt today. Traded prices for standard-quality copper were between RMB 66,150-66,300/mt, and RMB 66,200-66,500/mt for high-quality copper. SHFE copper prices continued to fall, and both imported copper and hedged copper continuously arrived in the spot market. Besides, the price gap between SHFE 1109 and 1110 copper contracts was more than RMB 500/mt, which caused discounts to expand. Although there were some buyers making purchases at low prices, market surpluses dampened transactions.
