**Iran’s parliament and its National Security and Foreign Policy Commission approved measures in early October 2026 authorizing fees for navigation, environmental, insurance, security, and related services in the Strait of Hormuz, with payments potentially required from authorized vessels in rials or other currencies.** These steps build on earlier 2026 proposals and the establishment of the Persian Gulf Strait Authority, which has coordinated with Oman and reportedly collected service-related payments from some vessels—ranging from ad hoc charges to figures cited around $150,000–$2 million depending on cargo and arrangements—while blacklisting non-compliant ships. A prior 60-day toll-free window tied to a June memorandum has expired amid ongoing regional tensions. U.S. officials, including Secretary of State Marco Rubio, have rejected any toll or mandatory service fee regime as unacceptable under international law governing transit passage. Upcoming factors include full parliamentary and Guardian Council action on related bills, further diplomatic coordination with Gulf states, enforcement consistency, and any new bilateral deals or U.S. responses that could alter implementation timelines. Trader consensus on near-term resolution reflects these legislative and operational signals alongside legal and diplomatic constraints.
