如果欧美谈崩了，会发生什么？

Core Viewpoint - The EU is preparing a robust countermeasure strategy as the deadline for trade negotiations with the US approaches, which could escalate transatlantic trade disputes and significantly impact both economies [1][2]. Group 1: Economic Impact of Tariffs - Current US tariffs of approximately 10% on EU goods have resulted in about a 0.4% GDP loss for the EU [2]. - If a 15% tariff agreement is reached, this loss is expected to rise slightly to 0.5% [2]. - In the worst-case scenario, if the US imposes a 30% punitive tariff, the effective average tax rate would increase to about 21%, leading to a GDP decline of 0.7% for the EU [2]. Group 2: EU's Two-Step Retaliation Plan - The EU's retaliation strategy consists of two phases: the first involves imposing tariffs on a total of €930 billion worth of US imports, potentially at rates as high as 30% [3]. - The second phase includes the potential activation of the Anti-Coercion Instrument (ACI), targeting US financial and digital services [3]. Group 3: Anti-Coercion Instrument (ACI) - The ACI, established in November 2023, serves as a trade "defensive weapon" aimed at deterring third countries from exerting economic pressure on the EU [4][5]. - Unlike traditional trade dispute tools, the ACI allows for broader measures, including restrictions on foreign direct investment and access to financial markets [4]. Group 4: Risks of ACI Activation - Utilizing the ACI against US financial and digital services could lead to "significant self-harm" for the EU, given its reliance on US technology service imports [6]. - Any US countermeasures in response to ACI activation could severely disrupt European business activities [6].
