特朗普发布“登岛图”，格陵兰岛会成为新一轮美欧贸易战催化剂吗

Core Viewpoint - The ongoing tensions between the U.S. and Europe regarding tariffs and trade, particularly concerning Greenland, could escalate into a new trade war, significantly impacting global GDP growth and trade dynamics [1][3][4]. Group 1: Economic Impact - The Oxford Economic Institute's model indicates that the trade conflict could reduce global GDP growth to 2.6%, down from the stable range of 2.8%-2.9% observed over the past three years [1]. - The potential tariffs could lead to a 0.3 percentage point decrease in GDP growth for the U.S., Eurozone, and the UK, with the U.S. GDP growth expected to drop to 2.3% by 2026 [3][4]. - The trade conflict is projected to have a more prolonged and severe impact on Europe compared to the U.S., particularly affecting open economies like Germany [3]. Group 2: Tariff Dynamics - The European Union is considering imposing tariffs on $930 billion worth of U.S. goods, which represents 28% of the total U.S. exports to the EU in 2024 [1]. - If the U.S. implements the proposed tariffs, the overall tariff increase would reach 2.8 percentage points, raising the average tariff rate to 16.8%, the highest since spring of the previous year [5]. - The Oxford Economic Institute suggests that the tariffs could lead to a significant reduction in U.S. exports to targeted countries, estimating a 50% decrease compared to pre-2025 levels [5]. Group 3: Political and Legal Considerations - Discussions are ongoing regarding the legal basis for the U.S. tariffs, with the U.S. Supreme Court set to rule on the International Economic Powers Act (IEEPA), which could influence tariff assumptions [7]. - The potential for a compromise exists, with the U.S. possibly delaying the February tariff increase while maintaining the threat of June tariffs [6]. - The U.S. Geological Survey has identified 60 minerals in Greenland that are crucial for U.S. economic and national security, complicating the geopolitical landscape surrounding the territory [6].
