European Central Bank President Christine Lagarde abruptly left an exclusive Davos dinner after US Commerce Secretary Howard Lutnick began criticizing Europe. The incident, confirmed by people familiar with the matter, underscores the tense transatlantic relations at this year's World Economic Forum.

The walkout highlights growing friction between US and European officials over trade and economic policy. Lutnick's comments, while not detailed in the report, likely touched on regulatory differences and market access. Such public spats can unsettle investors already navigating geopolitical risks.

Market participants will watch for any formal response from the ECB or European Union. The episode may complicate ongoing negotiations on trade and digital regulation. For investors, it signals potential volatility in eurozone assets if political tensions spill into economic policy.
