Donald Trump has reignited concerns over tariffs, particularly affecting Stellantis, the automotive group, which saw its stock decline significantly on the Paris stock exchange. Trump's threats to increase tariffs on products from China, Canada, and Mexico have led to a notable drop in Stellantis shares, prompting speculation about the company's future strategies. The broader market also reacted negatively, with the CAC 40 index closing lower amid these developments. Additionally, semiconductor companies Nvidia and Intel, along with their suppliers, are reassessing their operations in Mexico due to the potential impact of Trump's tariff proposals. This situation underscores the ongoing volatility in the markets influenced by trade policy announcements.
