Core Viewpoint - Copper prices are expected to remain volatile in the short term, with potential upward movement in Q4 due to recovering demand from the power grid and air conditioning sectors, despite current inventory pressures [4][5]. Macro Environment - The probability of a Federal Reserve rate cut in September has increased, leading to a weaker US dollar this week [4]. Supply and Demand - The inventory arbitrage logic between the US and non-US regions has ended, with previously stored inventory in the US becoming more apparent, leading to short-term accumulation pressure on LME and COMEX [4]. - Domestic cable operating rates have rebounded but remain significantly lower than the same period last year, with air conditioning production expected to decline year-on-year from August to October [4]. Inventory Levels - Domestic copper social inventory increased by 10.6% week-on-week, while LME copper inventory rose by 11.5% [5]. - As of August 8, 2025, domestic port copper concentrate inventory stood at 620,000 tons, up 18.8% from the previous week [5]. Raw Materials - The price difference between refined copper and scrap copper decreased by 21 CNY/ton this week [6]. - China's refined copper production in May was 158,000 tons, up 22.7% month-on-month and 11.2% year-on-year [6]. Smelting - The TC spot price was -38 USD/ton, reflecting a 4 USD/ton increase from the previous week, but still at a low level not seen since September 2007 [7]. - China's electrolytic copper production in July was 1.1743 million tons, up 3.5% month-on-month and 14.2% year-on-year [7]. Demand - Cable operating rates increased by 2.6 percentage points week-on-week, with cable demand accounting for approximately 31% of domestic copper demand [8]. - Air conditioning production is projected to decline year-on-year for the months of August to October, with refrigerator production also showing a downward trend [8].
