Global stock markets have taken a hit as China imposed new tariffs in response to the US, raising concerns about a worldwide economic downturn. The S&P 500, Dow, and Nasdaq all recorded substantial losses, with the S&P 500 facing its largest decline since 2020. US companies heavily reliant on China suffered significant losses as well. The escalation of trade tensions between the two economic powerhouses has fueled worries about the impact on the global economy. Investors are closely monitoring the situation for further developments that could potentially exacerbate the market turmoil.
