Tehran has announced new maritime regulations for the Strait of Hormuz, explicitly barring vessels linked to the United States and Israel from 'non-hostile passage.' This move threatens to disrupt the flow of 20% of the world's oil supply and significantly increases insurance and security risks for global shipping.
As US officials forecast a rapid conclusion to hostilities with Iran, Tehran counters with a strategy of long-term endurance. For global logistics, this standoff threatens the world's most vital energy artery and risks a systemic shock to maritime trade routes.
