On January 5, 2026, the first trading day after the New Year's holiday, the SMM A00 aluminum price surged by 850 yuan/mt in a single day, surpassing the largest single-day increase of any day in 2025. As a result, aluminum billet processing fees across regions rapidly pulled back, generally decreasing by 0–160 yuan/mt, but still remaining above the zero line. However, on the following day, January 6, 2026, the aluminum price soared another 600 yuan/mt, initiating an extreme market trend that lasted nearly two weeks—aluminum billet processing fees fell below the zero line and entered negative territory.
