According to market analysis, Chilean state-owned miner Codelco may have overstated its December 2025 copper production by around 20,000 mt after including material that may not have met finished product standards. Codelco previously reported December 2025 output of 172,300 mt, its highest monthly production level in nearly a decade and well above the January-November monthly average of around 105,600 mt. Following weaker production figures in January 2026 (91,000 mt) and March 2026 (110,900 mt), market attention has increasingly shifted toward the accuracy of the company’s previously reported production data and internal control processes.

SHFE Copper Prices Fell With Slight Increase in End-User Orders, Shanghai Spot Copper Premiums Remained Under Pressure

Looking ahead to tomorrow, tomorrow is the last trading day for the SHFE copper 2605 front-month contract. In accordance with the SMM #1 copper cathode price assessment methodology, SMM consistently quotes based on the front-month contract. From the current market structure, the intraday SHFE copper price spread between futures contracts quickly dipped, ranging between Contango 70 yuan/mt and Backwardation 60 yuan/mt. End-user procurement orders saw a slight increase in volume, but not significantly. According to SMM, some downstream enterprises placed orders mostly around 104,000 yuan/mt, and downstream procurement sentiment remained relatively subdued, with high copper prices continuing to suppress current consumption demand. However, due to the delivery logic providing a floor, spot discounts received certain support, and the downside room for premiums was limited. Going forward, attention should be paid to the outflow of unmatched warrants. After delivery is completed, the market is expected to enter a new round of pricing dynamics centered around the 2606 contract.
