Saudi Aramco shares soared 4.9% on Sunday, their biggest gain since May 2023, as the Iran conflict intensified, threatening global oil supplies. The surge followed Brent crude hitting $90 a barrel on Friday, with analysts warning prices could reach $100 if hostilities continue. Aramco is redirecting shipments to the Red Sea to avoid the Strait of Hormuz chokepoint, but Goldman Sachs cautioned capacity limits exist. The UAE, Kuwait, and Bahrain reduced production amid the near-closure of the vital waterway, adding to disruptions affecting worldwide energy exports. For Aramco, higher oil prices offset export declines, though attacks on its Shaybah and Berri fields pose risks.
