SHANGHAI, Aug. 6 (SMM) – In the Shanghai physical market, copper was offered between a RMB 50/mt discount and a RMB 20/mt premium over the SHFE 1408 copper contract. Traded prices were RMB 50,330-50,430/mt for standard-quality copper and RMB 50,360-50,480/mt for high-quality copper. Physical copper initially managed to trade at a low premium after SHFE copper prices tumbled, with standard-quality and hydro-copper prices holding firm due to tight supply. Middlemen entered the market actively during the morning trading session, while downstream producers went bargain-hunting after prices fell, with slightly better trading on Wednesday.
