    Oil trades above $100 as Strait of Hormuz disruption lifts diesel margins

    Question

    Oil trades above $100 as Strait of Hormuz disruption lifts diesel margins

    Direct answer

    Crude oil moved above the $100 per barrel threshold amid operational disruptions in the Strait of Hormuz and heightened Iran conflict concerns. Distillate fuel markets responded with sharp price spikes. Pure-play refining assets like Marathon Petroleum are capturing wider crack spreads between raw feedstock and refined diesel. Integrated majors face higher input costs and capital commitments, leading to diverging performance across the energy complex.
