Investment Rating - The industry rating is "Positive" with expectations for overall sector returns to outperform the benchmark index by more than 10% [5]. Core Viewpoints - The easing of the Israel-Iran conflict has led to improved market sentiment, coupled with increasing expectations for interest rate cuts by the Federal Reserve, which has positively impacted the non-ferrous metals sector [10][11]. - The anticipated reduction in overseas smelting capacity is gradually materializing, while there are still expectations for reductions in Chinese smelting capacity [3][10]. - Despite uncertainties in the macroeconomic environment and demand side, a turning point is awaited [4][10]. Summary by Sections Market Dynamics - Following the easing of the Israel-Iran conflict, market focus has shifted to liquidity and the potential impact of U.S. copper tariffs [2][10]. - The market is currently pricing in an implied tariff of approximately 13% on U.S. copper, with potential for further widening of price differentials if tariffs are implemented [10][11]. Supply and Demand - Overseas smelting reductions are expected to lead the way, with notable reductions already seen in facilities such as Glencore's PASAR smelter in the Philippines [10]. - In China, the current TC spot price is at -44.8 USD/dry ton, indicating a tight copper supply situation, further exacerbated by a reduction in guidance from the Kamoa copper mine [10][11]. Price Outlook - Copper prices are expected to rise in the lead-up to the implementation of U.S. tariffs, with the market currently reflecting a 13% tariff expectation [10]. - If monetary and fiscal policies support economic stability, a turning point for copper prices may be on the horizon, despite current uncertainties in the U.S. economy [10][11]. - Demand in China is expected to weaken marginally in the second half of the year, but this is not anticipated to significantly impact copper prices due to low inventory levels [10].
