The intraday trading activity decreased compared to yesterday, primarily due to the SMM Copper Industry Summit, where most traders were concentrated on-site, and suppliers stood firm on quotes for shipments. At the beginning of the morning session, standard-quality copper with a premium of 150 yuan/mt was quickly snapped up. After a small amount of low-priced goods were instantly sold, the mainstream quotations for standard-quality copper were at a premium of 160-180 yuan/mt. Following the transaction of high-quality copper, such as Jinchuan (plate), with a premium of 170 yuan/mt, the mainstream quotations rose to a premium of 180-200 yuan/mt.
