European stock markets were poised to open lower on Monday, continuing the downward trend from the last session following US President Donald Trump's announcement of a 30% tariff on imports from the European Union and Mexico, effective August 1. European Commission President Ursula von der Leyen reiterated the EU's commitment to reaching an agreement before the deadline, while also emphasizing that the bloc is prepared to take necessary measures to protect its interests. Reports indicate that the EU is intensifying discussions with other affected countries, such as Canada and Japan, which may lead to coordinated responses. With no major economic data or earnings reports scheduled in Europe today, trade developments remain the main influence on market sentiment. In premarket trading, Euro Stoxx 50 futures declined by 0.7%, and Stoxx 600 futures fell by 0.5%.
