SMM June 8:

Data Summary: As of Monday, June 8, SMM copper inventory in major regions across China fell WoW to 233,000 mt, up 83,500 mt from 149,500 mt in the same period last year.

Specifically, in Shanghai, warehouse withdrawals were steady, but arrivals of imported and domestic copper cathode stayed low, leading to steady destocking. In Jiangsu, insufficient arrivals pushed inventory down in tandem; in Guangdong, tight supply persisted, while weaker copper prices drove concentrated restocking by end-users, further reducing regional inventory.

Market Outlook: In the short term, arrivals of imported and domestic copper are likely to stay low, keeping overall supply tight. On the demand side, the recent pullback in copper prices has spurred downstream purchasing sentiment, with demand recovering. A survey shows that the operating rate of copper cathode rod is expected to decline to 61.32% this week, down 4.41 percentage points WoW. Based on supply-demand dynamics, with tight supply and recovering demand in the short term, China's social copper inventory is expected to see slight destocking next week.

Data Source Statement: Except for publicly available information, all other data are processed by SMM based on publicly available information, market communication, and relying on SMM's internal database model. They are for reference only and do not constitute decision-making recommendations.

Affected by typhoon weather, some warehouses in east China experienced difficulties in picking up goods, and cargo withdrawals and transportation were impacted to a certain extent. According to SMM, due to strong winds and rainfall, road traffic efficiency declined in some areas, and cargo pick-up arrangements at warehouses were postponed. Additionally, traffic controls were implemented on the Hangzhou Bay Bridge due to weather conditions, restricting some processing enterprises in Zhejiang from heading to Shanghai to pick up goods. Some enterprises reported that, due to transportation disruptions and increased time costs, they might reduce their cargo pick-up arrangements in Shanghai in the short term and would instead wait for traffic to resume before making purchases.
