Copper Inventories in China's Major Regions Pull Back Overall, Shanghai Becomes the Only Destocking Region [SMM Weekly Data]

SMM May 18 News:

Data Brief: As of Monday, May 18, SMM copper inventories in major regions across China decreased by 400 mt WoW to 242,900 mt, with total inventories up 103,700 mt compared to the same period last year (139,200 mt).

Specifically, Shanghai saw continued inventory pullback—the only destocking region—due to the dual impact of tightening imported supply and declining domestic arrivals. Jiangsu saw overall stable domestic copper arrivals, but downstream procurement demand remained weak under the pressure of rising copper prices, resulting in a slight inventory buildup. Guangdong saw increased domestic arrivals, coupled with sluggish end-use consumption, leading to a concurrent inventory increase.

Market outlook: Supply side, the pace of short-term import arrivals slowed down, while domestic arrivals saw some increase, gradually easing the overall tight supply situation. Demand side, as copper prices gradually pulled back, downstream enterprises' willingness to stockpile improved slightly, but overall market sentiment remained cautious, with most maintaining a wait-and-see purchase pace. Survey data showed that the copper cathode rod operating rate is expected to pull back to 60.84% this week, down 2.81 percentage points WoW. Considering overall supply-demand performance, the current market exhibits slightly looser supply while end-users maintain only just-in-time procurement, and social inventory is expected to show an inventory buildup trend in the short term.
