Germany and Ireland are the EU economies most vulnerable to potential US tariffs, particularly in the pharmaceutical sector, which could see tariffs as high as 200%. Germany's economy could suffer a 0.4% GDP loss, while Ireland, with 53.7% of its exports to the US, could face significant risks. The overall impact on the EU economy is uncertain, with estimates suggesting a potential 0.3% GDP loss. The auto sector is currently the most affected, with a 25% tariff already imposed. The pharmaceutical industry is crucial for the EU, contributing significantly to jobs and GDP.
