Trump warns US may charge Strait of Hormuz tolls if Iran deal collapses

In his Truth Social post, Trump spelled out the contingency in unusually explicit language, writing that there would be “NO TOLLS” during the 60-day ceasefire and afterward “unless they are imposed by and for the United States of America, should the deal not be completed, for services rendered as the Guardian Angel to the countries of the Middle East for purposes of both past, present, and future reimbursement of costs.”
U.S. Central Command pushed back on claims the strait was shut by adding specific operational detail: it said “Commercial ship traffic in the Strait of Hormuz increased June 20” while U.S. forces continued operating in the general area to support freedom of navigation.
Iran’s official justification for closing the Strait, as reported by Iranian state media, did not mention tolls; Tehran instead attributed the closure to Israel and Hezbollah exchanging fire in Lebanon and said it had again closed the strait after “killing at least 16,” with Iran also blaming the U.S. for failing to restrain Benjamin Netanyahu’s forces.
Ahead of the expected Sunday Switzerland talks, Iran confirmed it was still sending representatives—after the talks were “abruptly canceled earlier in the week”—to meet with U.S. figures including Vice President JD Vance, Jared Kushner, and special envoy Steve Witkoff.
President Donald Trump threatened Friday to impose U.S. tolls on the Strait of Hormuz if a peace deal with Iran is not completed within 60 days. Writing on Truth Social, Trump said there would be "NO TOLLS" during the ceasefire period — but the U.S. could charge fees afterward as a "Guardian Angel" to the Middle East "for purposes of both past, present, and future reimbursement of costs." PBS NewsHour reported the statement came just after Iran announced it had closed the critical waterway.
About 21 million barrels of oil pass through the Strait of Hormuz every day — roughly 21% of global petroleum supply, according to the U.S. Energy Information Administration. Any disruption or new fee on that passage would send shock waves through energy markets worldwide. U.S.-Iran talks in Switzerland are set for Sunday, June 21, giving diplomats a narrow window to prevent Trump's contingency from becoming reality.
Trump's Truth Social post laid out the stakes in unusually blunt terms. The U.S. would charge tolls only "if imposed by and for the United States of America, should the deal not be completed." He framed the fees as repayment for America's role as protector of the region. Forbes noted the language ties the toll directly to the fate of the ongoing Lebanon ceasefire memorandum of understanding, or MOU.
The 60-day ceasefire MOU is designed to freeze Israel-Hezbollah fighting in Lebanon. Trump's envoys — Jared Kushner and Steve Witkoff — helped draft it. If the broader Iran deal collapses after those 60 days, Trump says the U.S. would start billing for its naval presence. That concept — charging allies for U.S. military protection — echoes Trump's past demands that South Korea and Germany pay more for U.S. troops stationed there.
Iran declared the Strait of Hormuz "officially closed" on June 19, citing the deaths of "at least 16" people in Lebanon. Iranian state media blamed Israel's strikes and said the U.S. failed to restrain Prime Minister Benjamin Netanyahu. Yahoo News reported that Tehran did not mention tolls — its justification was entirely framed around Lebanon and Israeli military action.
U.S. Central Command pushed back hard. CENTCOM said Iran "does not control the waterway" and reported that commercial ship traffic in the Strait actually increased on June 20. U.S. forces, CENTCOM added, were actively operating in the region to protect freedom of navigation. The military's message was clear: Iran's "closure" is more rhetoric than reality on the water.
The diplomatic path to avoiding those tolls runs through Geneva. U.S.-Iran talks had been "abruptly canceled earlier in the week" after preliminary terms fell apart. Iran has now confirmed it is still sending representatives to Switzerland on Sunday. The U.S. delegation will include Vice President JD Vance alongside Kushner and Witkoff, according to Bloomberg.
Experts warn the toll threat is legally explosive. Under customary international law — built on the 1982 UN Convention on the Law of the Sea — the Strait of Hormuz is an international waterway open to all ships. Any U.S. attempt to charge fees could end up before the International Court of Justice. Goldman Sachs analysts have estimated that a "security surcharge" on Hormuz shipping could add $5 to $10 per barrel to global oil prices, acting as a de facto tax on energy consumers from Europe to Asia.
If the Switzerland summit collapses a second time, Trump's toll threat moves from rhetoric to policy question. Energy markets are already jittery. The White House is betting that the threat of fees — combined with the Lebanon ceasefire deal — gives Iran enough incentive to keep talking. Trump's "Guardian Angel" framing positions the U.S. not as a peacekeeper but as a billable security contractor for the entire region.
Iran, for its part, sees the Strait as its own strategic lever. It has used the threat of closure before to pressure the West during nuclear talks. This time, Tehran is also linking the waterway to Lebanon — tying two separate conflicts into one diplomatic knot. Whether Sunday's talks can untangle that knot in 60 days will determine whether the toll threat becomes the most disruptive new fee in the history of global trade, according to PBS NewsHour.
