SHANGHAI, Apr. 11 (SMM) – In the Shanghai physical market, copper was offered Friday at premiums of RMB 200-280/mt over the SHFE current-month copper contract price. Traded prices were RMB 47,350-47,430/mt for standard-quality copper and RMB 47,400-47,480/mt for high-quality copper. As SHFE copper prices rebounded slightly and the price gap between the SHFE 1404 copper contract and the SHFE 1405 copper contract hovered around RMB 400/mt, cargo holders continued to push up physical copper premiums. Hydro-copper was barely found in the market. Middlemen entered the market to purchase copper, while downstream producers had higher buying interest as well ahead of the weekends, with a smaller amount of copper supply. Physical premiums rose further by the midday due to decreasing supply, and trading activity also improved slightly on Friday.
