China's top oil refiner Sinopec has reduced its refining activity by 10% amid escalating conflict in the Middle East and severe disruptions to shipping through the Strait of Hormuz. The company trimmed run rates as the widening war complicates crude oil deliveries, directly impacting supply chains. This reduction signals significant pressure on global oil markets already strained by geopolitical instability. The 10% cut represents a substantial operational shift for Asia's largest refiner, potentially affecting China's domestic fuel availability and international trade balances. Market analysts warn this development could exacerbate existing supply constraints, pushing prices higher as demand remains robust.
