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 sharp decrease was primarily influenced by the imposition of new trade tariffs by the United States, sparking concerns of a potential trade war and causing a ripple effect across global markets. Noteworthy entities such as Aramco were among the companies that suffered substantial losses, contributing to an overall market value decrease of more than half a trillion riyals. The repercussions of this sudden plunge are being closely monitored by investors and analysts amid the prevailing economic uncertainties.
