Month-End Trading Thinned Out, Price-Holding Factors Drove Convergence of SHFE Copper Spot Discounts [SMM Shanghai Spot Copper]

Published: May 29, 2026 15:39
[SMM Shanghai Spot Copper] Looking ahead to next week, spot copper discounts are expected to continue narrowing slightly. Copper prices rose during the session, but the Contango price spread between nearby futures contracts widened slightly. Suppliers showed a strong willingness to hold prices firm, driving spot discounts to narrow marginally. Available supplies in the Changzhou area remained persistently tight, which may support local spot prices. However, as month-end approaches, market trading is turning sluggish, with downstream purchases driven mainly by rigid demand and limited willingness to chase higher prices, and overall transactions are expected to be just balanced. Overall, under the combined effects of suppliers holding prices firm and sluggish month-end trading, Shanghai spot copper prices against the SHFE copper 2606 contract are expected to remain at a discount, with the discount likely to move sideways.

SMM, May 29:

Looking ahead to next week, Shanghai spot copper discounts are expected to continue narrowing slightly. Intraday, copper prices rose, but the inter-month Contango spread widened slightly. Suppliers showed a strong willingness to hold prices firm, driving spot discounts to narrow slightly. Available cargoes in Changzhou remain tight, which is expected to support local spot prices. However, as month-end approaches, market trading activity is likely to turn sluggish, with downstream purchasing driven mainly by rigid demand and limited willingness to chase higher prices. Overall transactions are expected to be balanced. In summary, under the combined effects of suppliers holding prices firm and sluggish month-end trading, spot Shanghai copper prices against the 2606 contract are expected to remain at a discount next month, with the discount likely to move sideways.
