Oil prices are poised for a sharp increase when trading resumes Sunday night, as unprecedented U.S. and Israeli strikes on Iran have escalated tensions in the Middle East and raised fears of potential disruptions to global energy supplies. Since the start of the year, prices have been underpinned by persistent geopolitical risks.
