A Pronounced Recovery in Consumption and Continued Declines in Spot Inventory Drove Premiums Higher [SMM South China Spot Copper Cathode Weekly Review]

Published: Mar 12, 2026 16:14

SMM, March 12:

Guangdong: Spot premiums in the region continued to rise this week. Lower copper prices, coupled with an increase in terminal orders, lifted consumption among copper processing enterprises, driving inventory lower and supporting higher spot premiums. As of Thursday, high-quality copper was quoted at 160 yuan/mt, up 160 yuan/mt from last Thursday; standard-quality copper was quoted at a premium of 40 yuan/mt, up 240 yuan/mt from last Thursday; and SX-EW copper was quoted at a discount of 20 yuan/mt, up 240 yuan/mt from last Thursday. On Thursday, the price spread in standard-quality copper premiums between Shanghai and Guangdong stood at 0 yuan/mt. With the spread relatively small, there was no cross-region cargo transfer. According to SMM statistics, as of Thursday, total inventory in Guangdong warehouses was 90,800 mt, down 6,300 mt from last Thursday. Warrants totaled 51,300 mt, down 1,500 mt from last Thursday. As spot cargo supply decreased and discounts turned into premiums, warrants began flowing into the market. Specifically, warehouse arrivals this week were 13,100 mt/week, down 2,500 mt/week WoW and slightly below the annual average of 14,000 mt/week. Arrivals of both imported copper and domestic copper declined WoW this week. Warehouse withdrawals were 20,200 mt/week, up 8,600 mt/week WoW and far above the annual average of 14,200 mt/week. After the Lantern Festival, downstream enterprises fully resumed operations. In addition, many enterprises had not stockpiled much before the holiday, and actively replenished inventory after the holiday while copper prices remained low.

Looking ahead to next week, although delivery is approaching, spot cargo has already shifted to premiums. Suppliers are expected to show weaker willingness to deliver cargo to warehouses for delivery, and imported copper arrivals have also not increased. Total supply is expected to be slightly lower than this week. On the demand side, demand is expected to remain at this week's high level. Therefore, inventory is expected to remain in a state where demand exceeds supply next week, with inventory fluctuating lower, and spot premiums are expected to continue rebounding.
