European stock markets opened lower on October 19, reeling from days of looting and civil unrest in France and Italy. Protests against the rising cost of living turned into chaotic scenes in major cities like Paris, Marseille, Lyon, Bologna, and Turin. The French CAC 40 index dropped 1.28%, doubling expected losses, while French government bond yields saw a renewed rise, reflecting investor anxiety. While European markets struggled, Asian indices saw slight growth driven by China's strong quarterly economic performance. Meanwhile, American investors are monitoring debt levels in the AI sector and potential shifts in global oil supply following Donald Trump's policy announcements regarding Russian fuel.
