Escalating U.S.–Iran tensions are disrupting the critical Strait of Hormuz shipping corridor. Trump threatens to declare it U.S. territory while the U.S. blockades Iranian ports; Iran retaliates with threats to keep it permanently closed. Oil prices have risen 29% year-over-year, and only 2 vessels transited Friday versus 130+ normally. This directly threatens global energy supply and SME input costs, especially for fuel-dependent manufacturers and logistics firms in Thailand. New "unprecedented" U.S. sanctions on Iran are imminent, likely to drive energy prices higher over the next 1–2 weeks.
