The Inter-Month Price Spread First Showed a Backwardation Structure, and Shanghai Spot Copper Discounts Continued to Remain Under Pressure [SMM Shanghai Spot Copper]

Published: Mar 18, 2026 12:02
[Shanghai Spot Copper] Intraday trading in the spot market improved somewhat from yesterday. Suppliers still showed willingness to hold prices firm, but some suppliers’ sell-offs temporarily weighed on the market, causing spot premiums to decline somewhat in the second trading session. Coupled with the narrowing Contango price spread between nearby futures contracts, suppliers’ willingness to ship to delivery warehouses weakened somewhat, and spot premiums remained under pressure. Demand side, as copper prices fell, downstream enterprises may have had some restocking demand, but the current copper prices had limited actual appeal. Supply side, social inventory remained at a high level, but spot cargo available for actual circulation was relatively tight. Some warrants were already seen flowing out during the day, which may ease some pressure on spot supply. Meanwhile, the import window remained open, and expectations for subsequent inflows of cargo from outside China increased. Overall, amid the tug-of-war between sellers and buyers, Shanghai spot copper is expected to maintain the current discount structure overall tomorrow.

During the day, the SHFE copper 2604 contract declined somewhat, with its trading range shifting lower to around 98,100-98,500 yuan/mt. According to SMM communications, after the center of copper prices moved lower, market buying interest recovered markedly. Downstream processing enterprises reported that order volumes from end-users had risen recently, and they were actively replenishing raw material inventory amid the pullback in copper prices. At the same time, upstream smelters also reported strong buying sentiment in the spot market, with relatively active downstream procurement and smooth overall transactions. This round of pullback in copper prices stimulated previously suppressed restocking demand, and downstream enterprises showed strong willingness to buy the dip.
