Group 1 - The U.S. has imposed a 50% tariff on imported copper semi-finished products and copper-intensive derivatives, leading to a significant drop in copper prices by over 18% on the announcement day [1] - Copper ore and cathode copper have been exempted from tariffs, which was unexpected and has weakened previous market expectations of increased domestic copper production in the U.S. and decreased demand from non-U.S. regions [1][2] - The global market is currently experiencing high risk appetite, with positive performance in both domestic and international equity markets, which supports copper prices [1] Group 2 - The domestic macroeconomic environment in July has improved, with a general upward trend in pricing for various commodities, although the market sentiment has cooled towards the end of July [2] - Domestic electrolytic copper inventory depletion has slowed, while overseas copper inventories continue to accumulate, leading to a scenario where domestic prices are strong while international prices are weak [2] - The recent U.S. tariff policy has reduced disturbances to copper prices, and a new trade agreement may further lower global economic uncertainty, maintaining high market risk appetite [2][3] Group 3 - The joint statement from the U.S.-China Stockholm economic and trade talks indicates a 90-day extension of tariffs and adjustments to non-tariff measures, which is expected to positively influence copper price trends [3] - Overall, the macroeconomic environment is favorable for copper prices, while the industrial sector shows a neutral to bearish trend, suggesting a potential continuation of the pattern where domestic prices are strong and international prices are weak [3]

1. Report Industry Investment Rating No relevant content provided. 2. Core View of the Report - The copper price is expected to continue the pattern of being stronger in the domestic market and weaker in the international market, as well as being weaker in the near - term and stronger in the far - term. Currently, the macro - environment is favorable for copper prices, while the industrial side shows a neutral - to - bearish trend [2][3][4]. 3. Summary According to Related Content Impact of US Tariff Policy - On July 30, the US President announced a 50% tariff on imported copper semi - products and copper - intensive derivatives starting from August 1. The New York copper price dropped by over 18% on the same day, and the spread between COMEX copper and LME copper quickly narrowed to the pre - tariff - expectation level. Copper ores and cathode copper were exempted from the tariff, which is beyond market expectations. This exemption is bullish for copper prices from a global supply - demand perspective. After the spread convergence, US copper imports may decline in the second half of the year, increasing non - US copper supply and being bearish for LME and SHFE copper [2]. Macroeconomic Factors - The current high global market risk appetite and the good performance of domestic and foreign equity markets are bullish for copper prices. The unexpectedly weak US non - farm data and lower - than - expected non - manufacturing PMI at the beginning of the month increased the expectation of a US economic slowdown and Fed rate - cut expectations, causing the US dollar index to fall. The market expects the Fed to cut rates three times this year, with a cumulative cut of 75 basis points [2]. - There is a risk of a macro - environment shift. If the US economy continues to weaken, copper prices will be under pressure; if the US economy stabilizes and the Fed cuts rates, it will be bullish for copper prices [3]. Domestic Market Conditions - In July, the domestic macro - environment was positive. With the "anti - involution" policy, domestic - priced commodities generally rose. The strong trend continued in late July but cooled down at the end of the month, and commodities entered an adjustment phase. The current spot industry is in the off - season, with limited impact on copper prices. Supported by the macro - environment, far - month copper contracts are stronger than near - month contracts. Domestic electrolytic copper inventory de - stocking has slowed down, while overseas copper inventory has been accumulating at a high level, resulting in the pattern of stronger domestic and weaker international copper prices. Domestic upstream smelters maintain high production, and refined copper imports are expected to increase, putting pressure on the domestic industry [3]. Trade Agreement and Its Impact - In August, the new US tariff policy was implemented, and the US reached new trade agreements with major global economies, possibly extending the current tariff policy for 90 days. This reduces global economic uncertainty and is expected to keep the market risk - appetite high, which is bullish for copper prices [3]. - The joint statement of the Sino - US Stockholm economic and trade talks on August 12, 2025, involving a 90 - day tariff extension and non - tariff measure adjustment, indicates an improvement in Sino - US trade relations and is also bullish for copper prices [4].
