[SMM Analysis:It was like holding up a collapsing tower]Over the past three years, as China's smelting capacity for primary smelting has been concentratedly commissioned, year-end negotiations between Chinese smelters and Antofagasta have been particularly challenging. Since the end of last month, Antofagasta consistently maintained its Benchmark offer to Chinese smelters in the mid-negative $10 from the first to the second round. During this period, the China Smelters Purchase Team (CSPT) and the China Nonferrous Metals Industry Association repeatedly stated their firm stance: they would not accept any long-term pricing system other than the Benchmark, would not accept a negative Benchmark result, and were determined to reduce primary smelting output. Expectations for production cuts in primary smelting among Chinese copper smelters grew stronger. Facing these difficulties head-on, Chinese smelters, with one leading enterprise arguing forcefully on principle and without conceding on other terms, finally reached a $0 agreement with Antofagasta on the night of December 19, paving the way for other participating Chinese smelters to follow suit. Prior to this, market pessimism was rampant, with bearish narratives circulating widely. Given the mining company's persistent negative offers over multiple rounds, the market generally expected Chinese smelters to reluctantly accept a negative figure, ushering in an era of negative annual contracts. From the outcome, these negotiations were nothing short of turning the tide and preventing a catastrophic collapse.
