被稀土打怕了，特朗普对铜征50%关税，中国铜产业有多强？

Core Viewpoint - The article discusses Trump's decision to impose a 50% tariff on copper, driven by concerns that copper, like rare earths, could become a critical industry that the U.S. is overly dependent on imports for [2][4]. Group 1: Tariff Implications - Trump's tariff aims to maintain the resilience of the U.S. copper supply chain, reflecting a broader strategy to reduce reliance on foreign imports, particularly from China [4][6]. - The U.S. copper industry has seen a decline, with only three smelters remaining, producing less than 3% of global refined copper, while needing to import over 800,000 tons annually [6]. Group 2: Comparison with Rare Earths - The U.S. once dominated the rare earth industry but has shifted to importing from China, leading to a decline in domestic production capabilities [4][6]. - Similar to rare earths, copper is essential for modern manufacturing, and the U.S. has historically been a major player in this sector until a rapid decline post-1997 [4][6]. Group 3: Global Industry Dynamics - China currently produces over 50% of the world's refined copper, exceeding 12 million tons annually, and has contributed to 75% of the global increase in copper smelting capacity since 2000 [6]. - From 2019 to 2024, global investments in the copper industry are projected to reach $55 billion, with China accounting for nearly half of this investment [6]. Group 4: Economic Challenges - Trump's approach raises questions about the feasibility of reshoring supply chains without addressing the underlying economic challenges, such as the Triffin dilemma, which complicates maintaining the U.S. dollar's status as a reserve currency while revitalizing domestic manufacturing [10][11]. - The article suggests that Trump's policies may provide short-term economic benefits but could lead to long-term risks for the U.S. economy, particularly regarding manufacturing and national debt sustainability [11].
