The Saudi stock market witnessed a significant setback on Sunday with a 6.78% decline, marking its worst daily drop in five years. This plunge was a direct result of the new US trade tariffs, sparking fears of a potential trade war and causing a global market rout. Key sectors and major companies such as Aramco were not spared from the turmoil, as they suffered substantial losses, ultimately resulting in the market value plummeting by more than half a trillion riyals.
