[Shanghai Spot Copper] Looking ahead to tomorrow, the Shanghai spot copper market is expected to remain in a tug-of-war. Copper prices declined somewhat during the day, and downstream enterprises showed stronger restocking sentiment, but considering the heavy concentrated purchases already made last week, actual incremental buying was relatively limited. Inventory side, according to SMM, combined social inventory in Shanghai and Jiangsu fell by about 41,600 mt, showing a sharp destocking trend. During the day, supplier quotations were steady at first and then declined, with suppliers actively selling as premiums rebounded, and the sell-off put pressure on spot prices. In addition, some suppliers had already quoted against the SHFE copper 2604 contract using cargoes with invoices dated next month during the day, indirectly reflecting moderate sales volume within the month and strong willingness to sell among suppliers. Overall, amid the tug-of-war between faster destocking and supplier sell-offs, Shanghai spot copper premiums are expected to remain at the current level tomorrow.
