Copper Social Inventory Slightly Destocked Weekly, with Clear Regional Divergence [SMM Weekly Data]

Published: Aug 10, 2026 14:13

SMM, August 10:

Data Summary: As of Monday, August 10, SMM copper inventories in major regions across China decreased by 900 mt WoW from last Monday to 118,000 mt, total inventories fell by 13,600 mt YoY from 131,600 mt in the same period last year, with divergent performances across regions.

Specifically, in Shanghai, arrivals contracted, but high copper prices suppressed downstream consumption, resulting in inventory buildup; in Jiangsu, domestic arrivals were relatively low, leading to slight destocking; in Guangdong, the export window opened, reducing domestic inflows and causing inventory to edge lower.

Market Outlook: Supply side, both domestic and imported copper cathode arrivals are expected to edge up in the short term, easing the tightness in market circulating supplies somewhat. Demand side, high copper prices dampened producers' production enthusiasm, downstream users only made just-in-time procurement, and typhoon disruptions hindered cargo pick-up at warehouses. A survey shows that the operating rate of copper cathode rod is expected to increase to 59.42% this week, up 1.12 percentage points WoW. Under the overall supply-demand pattern, domestic spot supply is marginally loosening while end-user procurement remains sluggish. This week, national social inventories of copper cathode are expected to show an inventory buildup trend.

[SMM Shanghai Spot Copper] Tomorrow, due to the impact of typhoon weather, cargo pick-up and transportation at some warehouses in east China will be restricted, and short-term cargo circulation efficiency will decline, providing some support to the spot market. However, trading was sluggish during the day. Affected by weather factors and high copper prices, downstream purchase willingness declined significantly, and purchases were mostly based on rigid demand. Some processing enterprises in Zhejiang reduced their cargo pick-up arrangements to Shanghai due to traffic restrictions, providing limited support from the demand side. On the inventory front, SMM recorded Shanghai social inventory at 78,300 mt, up 2,200 mt WoW from last Thursday; Jiangsu social inventory at 18,100 mt, down 2,400 mt WoW from last Thursday. Overall inventory changes in east China were limited, without reflecting significant supply pressure. Meanwhile, the backwardation spread between contracts widened to 240-310 yuan/mt. The spread between spot and futures widened, and some suppliers' need to roll positions and convert to cash increased, which may exert some pressure on spot premiums. Overall, with the combined effects of typhoon weather disrupting cargo circulation, the widening backwardation structure, and sluggish trading, it is expected that Shanghai spot copper against the 2608 contract will still maintain premiums tomorrow, but the overall center may fluctuate slightly. Attention should be paid to cargo pick-up and supply circulation at warehouses after the weather improves.
