Spot market: Guangdong inventory continued to decline today, marking an eighth consecutive day of declines, with arrivals remaining relatively low. As both copper prices and inventory fell, suppliers sharply held prices firm when selling, leading to a notable rise in premiums. Downstream users, faced with tight supply, were forced to accept higher premiums, and overall trading activity was moderate. The purchase sentiment for copper cathode in Guangdong today stood at 2.3, up 0.36 from the previous trading day, while the shipment sentiment stood at 2.84, down 0.27 from the previous trading day (historical data can be accessed via the database).

Overall, inventory fell for an eighth consecutive day to a new low for the year, and spot premiums rose sharply, but actual transactions were moderate.

Falling copper prices activate bargain hunting, while the approaching delivery and backwardation structure support SHFE copper premiums [SMM Shanghai spot copper]

[SMM Shanghai Spot Copper] Looking ahead to tomorrow, the intraday copper price center is expected to shift lower, boosting downstream buyers' willingness to restock at lower prices, with some processing enterprises reporting order releases. The month spread structure has shifted from contango to backwardation. Suppliers' delivery profits from holding positions rose, with a strong reluctance to sell. Low-priced available cargoes on the market were tight. After the quick deals of discounted materials in early trading, quotes continued to be raised, and the premium for high-quality copper has widened to 60-100 yuan/mt. Supply side, SMM recorded that Shanghai's social inventory on June 11 was 155,700 mt, down 11,400 mt from June 8, mainly due to concentrated maintenance by domestic smelters and reduced imported arrivals, with spot circulation remaining tight. Overall, under the combined effect of delivery logic, backwardation structure support, and marginal consumption improvement, Shanghai spot copper prices against the SHFE copper 2606 contract are expected to maintain a premium and sustain a firm trend.
