Global stock markets are experiencing significant declines as concerns grow over recent tariff announcements by Trump. The Japanese Nikkei index fell over 3%, sliding to an 8-month low, and is bracing for its worst week since 2020. Asian markets extended their losses, with fears of a global downturn leading to a selloff that affected major indices. Investors are reacting to ongoing uncertainty, particularly in tech and banking sectors, as worries about the potential economic impact of these tariffs intensify. Wall Street also faced a retreat following the tariff news, leading to a broader global market rout.
