On the macro front, the US August PPI data fell far below market expectations, indicating easing wholesale inflation pressures and reducing the likelihood of significant consumer price increases in the coming months, providing grounds for the US Fed to support an interest rate cut at next week's meeting. Trump also declared "Inflation is zero!" and urged an immediate, substantial rate cut, driving the US dollar index lower and benefiting copper prices. Fundamentally, supply and demand are in a tug-of-war: continued inflows of imported material and active selling by traders have kept spot copper supply ample, but high copper prices are dampening downstream purchasing sentiment. Price-wise, the market reaction has been relatively cautious. The weaker-than-expected PPI has reinforced expectations for rate cuts, shifting focus to today's CPI data. Copper prices are expected to continue fluctuating at highs today.
