On Thursday, significant declines were observed across Europe's leading stock exchanges. The STOXX 50 and STOXX 600 indices both fell by more than 2% amidst a global sell-off in response to President Trump's recent tariff announcement. This development spurred a widespread shift towards safer investments and intensified apprehensions regarding the repercussions on the global economy. The European Union is now contending with tariffs potentially reaching 20%, a situation that prompted a cautionary statement from European Commission President Ursula von der Leyen, warning of the "major blow" such measures could inflict on the worldwide economic landscape. She further confirmed that the EU is devising countermeasures in response. The market downturn was extensive, with significant losses witnessed in sectors such as basic resources and banking. On the corporate scene, companies like Siemens, Airbus, Essilor, Schneider Electric, BNP Paribas, UniCredit, and Intesa Sanpaolo experienced share price drops exceeding 3%. Additionally, ASML Holding decreased by nearly 2.9%, while LVMH recorded a decline of over 2%.
