US declares guardian role in Hormuz, Iran issues warning

The president announced on his social media account on July 13, 2026, that the United States would act as the "Guardian of the Hormuz Strait" and keep the waterway open while seeking reimbursement via a proposed 20% cargo fee for security services. Iran's Khatam al-Anbiya military command spokesperson, Ebrahim Zolfaqari, replied the same day that Tehran would never accept U.S. interference in management of the strait and warned that any regional state providing logistical support to U.S. operations would bear responsibility for escalation.

US fee plan and Tehran's response

The announcement ties sovereign security operations to an explicit commercial charge, a shift from traditional naval assurance missions to a cost-recovery model. Officials described the proposal as a way to offset U.S. expenditures; the president framed it as ensuring uninterrupted transit through one of the world's busiest oil chokepoints. The Iranian spokesman framed the move as a red line and assigned potential culpability to regional partners that assist U.S. forces.

The immediate practical effect will be diplomatic pressure on Gulf states that host or support U.S. basing and logistics. Shipping companies and insurers are likely to seek clarity on fees and escort arrangements; carriers may route or price shipments differently if implementation details appear. Military posturing or added naval transits would raise accident and miscalculation risks in the narrow channel.

Expect further public statements or operational details from U.S. or regional authorities by July 20, 2026, which will be the next market and diplomatic test of whether the declaration becomes policy or remains rhetoric.
