The Saudi stock market witnessed a significant downturn on Sunday, marking its biggest daily plunge in five years with a 6.78% drop. This sharp decline came in response to the new US trade tariffs, causing a ripple effect across global markets and sparking concerns of a potential trade war. Notable sectors and companies such as Aramco were heavily impacted, resulting in a substantial decrease in market value amounting to over half a trillion riyals. The repercussions of this downturn are being closely monitored by investors and economists alike as they assess the broader implications for the global economy.
