US officials have consistently rejected proposals for mandatory transit fees or tolls on the Strait of Hormuz, an international waterway, citing legal barriers under maritime conventions and longstanding policy on freedom of navigation. In mid-July 2026, President Trump briefly proposed a 20% cargo-value reimbursement for US naval protection before reversing course in favor of separate Gulf state investment and trade commitments to the United States. Iranian and Omani plans for service or voluntary fees have advanced through bilateral talks but face US opposition, with recent reporting noting stalled progress on broader shipping agreements. Trader sentiment reflects these diplomatic frictions, Gulf state positions, and the absence of concrete US fee implementation steps, alongside scheduled negotiation deadlines into late August 2026 that could clarify outcomes.
