Summary of J.P. Morgan's China Metals Activity Tracker Industry Overview - The report focuses on the metals industry in China, specifically tracking inventory trends for steel, iron ore, copper, aluminum, and zinc as of the week ended July 18, 2025 [1][11]. Key Insights 1. **Copper Inventory Trends** - China typically experiences significant destocking of copper inventories from now until September. However, recent data shows a slowing pace of inventory drawdowns, with copper inventories increasing by 3,000 tons last week [1][12]. - The five-year average indicates a normal destocking of approximately 200,000 tons of copper during this period [1][12]. 2. **Steel Mill Margins** - There has been a notable improvement in China steel mill margins over the last three weeks, leading to a ~10% increase in iron ore prices to $102 per ton. Average hot-rolled coil (HRC) steel mill margins have returned to profitability for the first time since early 2023 [2][9]. - Rebar margins are close to breakeven, marking the strongest profitability since early 2023 [2][9]. 3. **Iron Ore Shipments and Production** - Iron ore shipments to China from Australia and Brazil have shown mixed results, with Australian shipments down by 4.3% week-over-week but up 8.2% year-over-year. Brazilian shipments increased by 23.9% week-over-week but decreased by 11.3% year-over-year [4][2]. - Total iron ore arrivals in China increased by 13.7% week-over-week, indicating a robust demand [4][2]. 4. **Impact of U.S. Tariffs on Copper** - A potential 50% tariff on U.S. copper imports, effective August 1, could reduce U.S. demand by approximately 4%, translating to a 0.2% decline in global copper demand [3][12]. - The U.S. exports around 540,000 to 580,000 tons of copper scrap annually, which could help mitigate a primary deficit of 700,000 to 800,000 tons per annum, although increased recycling capacity may take 2-3 years [3][12]. 5. **Physical Demand Indicators** - Despite recent increases in copper, aluminum, and zinc inventories, overall inventories remain at their lowest levels in over five years for this time of year, indicating tight physical markets [12][13]. - China's copper premium has risen by 70% in the last two weeks, reaching approximately $50 per ton, although it remains significantly below the year-to-date high of $103 per ton [12][13]. Additional Observations - The report highlights that the next ten weeks will be critical for assessing the health of Chinese physical copper consumers, as historical trends suggest a shift towards improved demand during this period [12][13]. - The report also includes detailed tables and figures illustrating inventory levels, shipment data, and price forecasts for various metals, providing a comprehensive view of the current market dynamics [4][9][34]. Conclusion - The J.P. Morgan report provides valuable insights into the current state of the metals industry in China, highlighting trends in inventory, pricing, and the potential impact of U.S. tariffs on copper demand. The data suggests a complex interplay of supply and demand factors that investors should monitor closely.
