European equities were poised for a sluggish start on Tuesday as markets reopened following the extended Easter holiday. Market sentiment took a hit after President Donald Trump intensified his criticism of Federal Reserve Chair Jerome Powell, sparking renewed concerns about the central bank's autonomy. The global market atmosphere was further destabilized by the protracted deadlock in trade talks, with China steadfastly standing firm against Washington's assertive tariff measures. With no significant economic data releases or corporate earnings announcements slated for Europe today, investors remained fixated on international developments. In early premarket activity, Euro Stoxx 50 futures slipped 0.7%, while Stoxx 600 futures edged down 0.3%.
