The Saudi stock market witnessed a significant downturn on Sunday, recording its most substantial daily decline in five years with a 6.78% drop. This drastic fall was primarily attributed to the introduction of 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 hit hard, with substantial losses incurred, resulting in the market shedding over half a trillion riyals in value.
