The Saudi stock market witnessed a significant decline on Sunday, marking its worst daily drop in five years with a 6.78% fall. This plunge came in response to the new US trade tariffs, causing a ripple effect across global markets and sparking concerns of an impending trade war. Notable sectors and companies such as Aramco were not immune to the downturn, as they suffered substantial losses, resulting in the market shedding over half a trillion riyals in value.
