Inventory Hit a New Low for the Year with Premiums Staying High, but Beware of Weakening Consumption Dragging Down Premiums [SMM South China Copper Cathode Spot Weekly Review]

Published: Apr 9, 2026 11:57

SMM April 9 Update:

Guangdong region: Premiums in this region bottomed out and rebounded this week. After the holiday, copper prices surged briefly, weakening downstream demand and pushing premiums lower. However, as inventory continued to decline and hit new lows, premiums rose again. As of Thursday, high-quality copper was quoted at 190 yuan/mt, down 10 yuan/mt WoW; standard-quality copper premiums were at 120 yuan/mt, up 10 yuan/mt WoW; and SX-EW copper was quoted at 60 yuan/mt, up 10 yuan/mt WoW. On Thursday, the price spread of standard-quality copper premiums between Shanghai and Guangdong showed Guangdong higher by 130 yuan/mt, with the spread narrowing WoW and no cross-regional cargo transfers occurring. According to SMM statistics, as of Thursday, total inventory in Guangdong warehouses stood at 35,000 mt, down 10,500 mt WoW and down 62,700 mt from the annual high. Warrants totaled 18,800 mt, down 7,600 mt WoW. Specifically: warehouse arrivals this week were 9,900 mt/week, up 1,700 mt/week WoW, far below the annual average (14,000 mt/week). Some suppliers increased shipments to warehouses during the Qingming holiday, which was the main reason for the increase in arrivals. Warehouse withdrawals were 21,000 mt/week, down 3,600 mt/week WoW, but still far above the annual average (14,200 mt/week). Downstream consumption pulled back after the Qingming holiday compared to pre-holiday levels, and we expect it to decline further next week.

 Looking ahead to next week, neither imported nor domestic sources are expected to see significant increases in arrivals, and supply is expected to remain tight. On the demand side, downstream consumption has shown signs of weakening since mid-week, and consumption is expected to decline further next week. Therefore, supply is expected to remain flat while consumption declines next week, destocking speed will slow down, and upside room for premiums is likely to be limited.

According to SMM, copper prices surged this week, significantly suppressing new order intake in the copper plate/sheet and strip industry. However, thanks to ample backlog orders accumulated in the earlier period, industry production demonstrated strong resilience. Demand orders from core downstream sectors such as power, new energy, and electronics remained generally stable, supporting full production schedules for most enterprises. As a result, the industry's operating rate continued to fluctuate at highs.
