Energy Flows & Costs: Reports say Middle East crude exports rebounded in September and Saudi oil routes shifted toward the Strait of Hormuz after Red Sea disruptions, while Saudi leaders warned of an energy crisis with uncertain outcomes. Regional Defense Pacts: Analysis highlights the Makkah Defense Alliance and debate over how far Pakistan’s commitments could extend as Yemen’s conflict intensifies.
