SHANGHAI, Feb. 5 (SMM) –Shanghai spot copper discounts were quoted between negative RMB 140-280/mt in the morning business. Traded prices for standard-quality copper were between RMB 58,800-58,850/mt, and RMB 58,870-58,950/mt for high-quality copper. SHFE copper prices slipped slightly, but spot copper cargo-holders took the last chance to sell goods ahead of the Chinese New Year holiday, leading copper discounts to expand. However, cargo-holders of standard-quality copper became reluctant to insist on firm prices, so the price gap between standard and high-quality copper widened. Nevertheless, spot copper supply decreased after cargo-holders became less eager to move goods, which helped copper discounts shrink. More traders and downstream producers opted to exit from markets, turning market activity more lackluster.
