Trump Rejected Iran’s Seven-Day Hormuz Plan. How Did One Strait Become the Bargaining Chip?

Iran’s plan came out of the first substantial US–Iran contact in months. On 22–23 September, on the sidelines of the UN General Assembly in New York, US envoys Steve Witkoff and Jared Kushner held indirect talks with Araghchi, with mediators carrying messages between rooms. Trump later described it as a three-hour meeting. Witkoff called the talks “promising” and “constructive”.

On Friday 25 September Araghchi made the terms public. Iran said the US steps could be completed in four to five days, allowing the strait to reopen and negotiations to begin by day seven. Iran formally submitted the roadmap through Qatar the same day. The sequence closely resembles the 17 June memorandum, on a faster clock. Araghchi also pitched a quick deal as helpful to Trump before November’s US midterm elections.

Speaking to reporters on 26 September, Trump said: “They want to make a deal, and I think that’s fine. I’d like to make a deal, too.” But the Iranian plan “would not be acceptable”. “I reject their proposal.” Iran, he said, wanted to open the strait immediately only “because they’re losing so badly”. An administration official added that the US was “not in a rush”.

Four reasons stand out in the public record:

Iran’s reply was firm but not final. Araghchi said Iran “will not back down” on its conditions and was waiting for “the definitive opinions to be conveyed to us by the mediators”. He added that “Iran does not accept coercion, threats, or intimidation”. President Masoud Pezeshkian told Al Jazeera that Tehran had “no trust in the American side”. On 27 September Araghchi told state broadcaster IRIB that “any move toward reopening the Strait of Hormuz is contingent upon these conditions being fulfilled.”

Then, the same day, Trump signalled the door was still open. In a phone interview with Axios he said he expected more talks that week: “They want to make a deal, but it is not the deal that I want to make.” Qatari mediators arranged separate meetings with Araghchi and Witkoff for 28 September. The Wall Street Journal separately reported that Trump expected renewed bombing of Iran after the midterms if no deal was reached. That is a report of his expectations, not an announced decision.

As he rejected the plan, Trump posted an image on Truth Social showing the waterway relabelled “Trump Strait”, reported by NBC News, AP and CNN. It was a political message about who holds the upper hand, not a formal act. Geographic names at sea are not changed by a post, and no government, the UN or the International Hydrographic Organization has adopted the label.

The strait joins the Persian Gulf to the Gulf of Oman and the Arabian Sea. Iran lies to the north; Oman’s Musandam exclave and the UAE to the south. At its narrowest it is about 21 miles (34 km) wide, and the inbound and outbound shipping lanes are each only a couple of miles across. Saudi Arabia, Iraq, Kuwait, the UAE, Qatar and Iran itself all ship oil or gas through it.

That last number is the whole problem. Saudi Arabia’s East-West Pipeline to Yanbu on the Red Sea and the UAE’s Habshan–Fujairah line can move some oil around the strait. Kuwait, Qatar, Bahrain and Iraq’s southern fields have no comparable route. Qatar’s LNG, a fifth of world trade, has none at all. Hormuz is not irreplaceable, but it cannot be replaced at full scale.

The modern US–Iran contest over Hormuz began inside another war. During the Iran–Iraq War (1980–1988), Iraq started attacking tankers serving Iranian ports in 1984. Iran answered by hitting ships trading with Iraq’s Gulf backers, above all Kuwait. More than 400 commercial vessels were attacked over the course of what became known as the Tanker War.

Kuwait asked for protection. In July 1987 the United States began Operation Earnest Will, re-registering Kuwaiti tankers under the American flag and escorting them through the Gulf. It was the largest naval convoy operation since the Second World War. On the first convoy, the reflagged supertanker Bridgeton struck an Iranian mine.

On 14 April 1988 the frigate USS Samuel B. Roberts hit an Iranian mine and nearly sank. Four days later, on 18 April, the US launched Operation Praying Mantis, destroying two Iranian oil platforms and sinking or disabling several Iranian warships, including the frigate Sahand. It was the largest US naval surface battle since 1945. On 3 July 1988, the cruiser USS Vincennes shot down Iran Air Flight 655 over the strait, killing all 290 people on board, an event that still shapes Iranian views of the US Navy in these waters.

For three decades after 1988 the strait stayed open, but every crisis between Washington and Tehran ran through it. In January 2008, Iranian Revolutionary Guard speedboats swarmed three US warships in the strait. In December 2011, as the US and EU prepared oil sanctions, Iranian officials threatened to close Hormuz altogether; they did not.

In 2019, after the US left the nuclear deal and pushed Iran’s oil exports towards zero, four ships were sabotaged off Fujairah in May and two tankers were attacked in the Gulf of Oman in June. The US blamed Iran, which denied it. Iran shot down a US Global Hawk drone on 20 June and seized the British-flagged Stena Impero in the strait on 19 July. In 2023 Iran seized the tankers Advantage Sweet and Niovi, and on 5 July tried to seize two more, TRF Moss and Richmond Voyager, before the US Navy intervened; Iran said it had a court order in the Richmond Voyager case. In April 2024 commandos took the container ship MSC Aries near the strait.

The lesson each time was the same. A ship does not have to sink for Hormuz to become a crisis. The perception of risk moves insurance premiums, shipping decisions and prices on its own.

On 28 February 2026 the United States and Israel launched strikes on Iranian military, nuclear and leadership targets. Iran retaliated against Israel and across the Gulf. On 2 March the Revolutionary Guards confirmed the strait was closed and threatened any ship that tried to cross. Brent crude passed $100 a barrel on 8 March and peaked near $126. On 26 March Araghchi announced that ships flagged to China, Russia, India, Iraq and Pakistan could transit, a carve-out that set the crisis’s shape: near-total disruption for most, selective passage for a few.

A two-week ceasefire was agreed on 7–8 April. Face-to-face talks in Islamabad on 11–12 April failed, and on 13 April the US Navy began blockading Iranian ports. On 17 April, during a Lebanon truce, Iran declared the strait “completely open”. The next day it closed it again, because the US would not lift the blockade. On 21 April Trump extended the ceasefire until talks were “concluded, one way or the other”, while keeping the blockade in place.

On 3 May Trump announced that the US would “guide” stranded ships out of the Gulf, calling it a “humanitarian gesture”. Project Freedom began on 4 May and was paused on 6 May, with Trump citing “great progress” towards a deal. On 14 June both sides announced an agreement, and on 17 June Trump, at the G7 summit, and Pezeshkian, in Tehran, signed a memorandum of understanding. CENTCOM lifted the blockade on 18 June and the strait reopened, with nuclear questions left to a 60-day follow-on negotiation.

The memorandum did not hold. Iran closed the strait again on 20 June, citing Israeli violations of the Lebanon ceasefire, and on 27 June a Western maritime information centre announced a widened route near Oman to challenge Iran’s control. In early July Iran warned tankers to use Iranian-approved routes. After Iran struck commercial ships, the US hit Iranian military targets on 7 July. On 8 July, at the NATO summit in Turkey, Trump declared the ceasefire “over”, while letting Witkoff and Kushner keep talking.

On 12 July Iran said the strait was closed until further notice after striking a vessel on an unapproved route. CENTCOM answered that “the Strait of Hormuz is open to all vessels seeking to lawfully transit” and that “Iran does not control the strait.” On 13 July Trump announced the blockade would return and that the US would charge fees “at the rate of 20% on all cargo shipped” through Hormuz. The UN’s International Maritime Organization opposed transit fees. The blockade was reinstated on 14 July; the 20% fee was later dropped in favour of trade and investment deals with Gulf states.

August was a month of pressure rather than talks. On 8 August Iran issued a six-point list of demands for reopening. On 25 August US officials confirmed mine-clearing in the shipping lanes. By early September, the Wall Street Journal reported, the blockade had halted new Iranian oil exports from the Gulf, and Brent climbed back above $100.

Around 21 September, CENTCOMBy mid-September, CENTCOM’s commander said#8217;s commander, Adm. Brad Cooper, said Hormuz shipments had reached a six-month high after mines were cleared, though most routine traffic still stayed away. Meeting Araghchi in Beijing on 16 September, China urged both sides to “rebuild the negotiation mechanism”. The UN General Assembly gave them the venue: indirect talks on 22–23 September, Iran’s offer on 25 September, Trump’s rejection on 26 September and his prediction of more talks on 27 September. On 27 September the Revolutionary Guards also claimed to have captured a second US underwater drone; CENTCOM denied it, calling the claim “clearly desperate”.

In 2026 the word “open” has been used for at least five different situations. The US says Hormuz is open because international law gives ships the right of transit and the US Navy will defend it. Iran says it is closed because Iran will attack or turn back ships that do not coordinate with it. Shipowners decide on insurance and crew safety, not on either statement.

According to the EIA, 89% of the crude and condensate that crossed Hormuz in the first half of 2025 went to Asian markets, and China, India, Japan and South Korea took 74% between them. For India, which imports most of its crude and much of its LNG from Gulf producers, a disrupted strait feeds through to petrol and diesel prices, fertiliser and petrochemical costs, shipping rates and inflation.

India has been both exposed and partly protected. Indian seafarers were among those killed in attacks on ships in March 2026, and on 13 May the Indian-flagged cargo ship Haji Ali sank off Oman after being struck. But Indian-flagged vessels were among the five flags Iran allowed through from 26 March. That carve-out keeps some Indian cargoes moving, and it gives New Delhi a stake in any deal that decides who gets to pass.
