President Trump’s July 2026 announcement that the United States would act as “guardian” of the Strait of Hormuz and seek 20 percent reimbursement on cargo value for naval protection triggered brief market movement, but the rapid reversal the next day—shifting to Gulf state investment and trade deals—sharply reduced implied probabilities. The International Maritime Organization has rejected any legal basis for mandatory tolls, while sanctions guidance highlights risks tied to Iranian fee demands. Ongoing U.S.-Iran frictions over shipping security and regional influence continue to shape trader views, yet no legislative or executive steps toward U.S. fees have materialized. Low odds across remaining 2026 resolution dates reflect expectations that diplomatic or commercial alternatives will prevail absent major escalation.

Any payment amount or rate will count. Payments may be monetary or in-kind (e.g., a share of cargo or oil) and may be collected directly by the US government or by an agent, contractor, or intermediary collecting on its behalf, provided the payment is made under a US-imposed fee or a compensation arrangement.
The announcement, signing, or establishment of a fee program, executive order, regulation, or collection mechanism will not by itself qualify; at least one payment must actually be received by the listed date, 11:59 PM ET.
Payments collected by Iran or any other party acting on its own behalf will not count. Payments under preexisting obligations, including US customs duties, tariffs on goods imported into the United States, or standard port charges, will not count unless newly imposed as a condition of Strait of Hormuz transit or protection.
The resolution sources will be official announcements from the government of the United States and a consensus of credible reporting.
