"[SMM Copper Spot] The mainstream spot copper premium remained flat at 230-270 yuan/ton, while the premium for high-quality copper increased to 250-320 yuan/ton. The monthly price difference continued to expand, with early trading fluctuating at 480-500 yuan/ton. The spot market focus today has shifted lower than yesterday, but the monthly price difference still expands. After the holders lowered the premium, downstream purchasing sentiment has improved compared to yesterday. It is expected that if the monthly price difference does not continue to expand, there will be support for spot copper premiums to stabilize from consumer demand."
