Trump Rejects Iran’s Seven-Day Hormuz Plan: What It Means for Latin America

Updated 1 times · Latest: 27 September 2026

President Donald Trump has rejected the Iran seven-day Hormuz plan, an offer to reopen the strait within a week if Washington met Tehran’s conditions. Iran’s foreign minister, Abbas Araghchi, had set out the plan in New York during the UN General Assembly.

The rejection matters far from the Gulf, because the strait stays shut and oil still costs about US$104 a barrel. Latin America is split by that price, between the countries that buy fuel and the ones that sell it.

What Changed on 27 September

Trump rejected the Iran seven-day Hormuz plan on 26 September, speaking to reporters as he left the White House. “That deal would not be acceptable,” he said, adding that Iran wanted a deal “because they’re losing so badly.”

He also said the United States already has total control of the strait, the Spanish news agency EFE reported. The Wall Street Journal had first reported his decision late on Friday.

Araghchi answered on 27 September that Iran would not retreat from its conditions, according to the Tasnim news agency. He said Tehran still awaits a formal reply through the mediators, identified by EFE as Qatar and Pakistan.

Oil has not traded since the rejection, so Brent’s last price is still Friday’s US$104.37 settlement. For Latin America, a shut strait means importers keep paying more and exporters keep their windfall.

What Iran Has Offered

Araghchi said Qatar passed the plan to Washington, according to the Anadolu Agency, Turkey’s state news agency. The clock would start the day after the United States accepted it.

Under the plan, fighting would stop on every front, including Lebanon, and the American naval blockade of Iranian ports would end. Washington would also waive sanctions on Iranian oil exports and release frozen Iranian funds, Al Jazeera reported.

The United States would take those steps over the first five days, and the strait would open on the sixth or seventh. Talks on a wider settlement would begin on the seventh day.

“The moment they accept this plan, from the next day, this timetable can start,” Araghchi said. He added that reopening the waterway would not mean concessions on Iran’s nuclear programme.

Washington’s Answer

President Donald Trump confirmed on 26 September that he had rejected the seven-day offer, as the Wall Street Journal first reported. The newspaper said he expects American bombing to resume after the midterm elections.

Before Trump spoke, the State Department had not closed the door. Its spokesman, Tommy Pigott, said it was not the United States that had stopped talks from happening.

A United States official told CBS News that the discussions were positive and constructive, but that Washington was in no hurry. The official said America held the stronger position.

Iran’s reading is the opposite. Araghchi said the choice now rested with the United States, and that Iran would not surrender sovereign rights under pressure.

Why the Strait Is Shut

The Strait of Hormuz is the channel between Iran and Oman through which about a fifth of the world’s oil normally moves. Iran closed it on 28 February, after American and Israeli air strikes began the war.

A ceasefire in June briefly eased the blockage, but it broke down in July. The United States reimposed a naval blockade of Iranian ports on 14 July, and the waterway has stayed effectively shut.

Traffic through the strait has fallen from about 20 million barrels a day to fewer than four million, the International Energy Agency estimates. American Central Command says it has turned back 122 commercial ships heading for Iranian ports.

Brent crude, the benchmark that prices most traded oil, settled at US$104.37 a barrel on Friday, down 2.09%. It cost about US$70 before the war and touched roughly US$150 in the first weeks of it.

The Bill for the Importers

Most of Latin America buys its fuel rather than making it. Chile, Peru, the Central American republics and the Caribbean islands import almost everything they burn, so a Gulf shortage lands on their pumps.

OLADE, the intergovernmental energy body for Latin America and the Caribbean, measured the damage done in March. Petrol prices across the region rose 15% that month, diesel prices 21%, and regional energy inflation reached 1.42%.

Chile shows what that costs a treasury, which was spending about US$140 million a week to hold pump prices down. In March the government let go, and petrol rose 44% and diesel 54% in a single week.

The Economic Commission for Latin America and the Caribbean, a UN body, expects energy to cost at least 25% more this year. It calculates that the trade balance of Central America, Haiti and the Dominican Republic could worsen by 0.9% of their output.

The Windfall for the Exporters

The other half of the region is selling into the shortage. Latin America pumped 11% of the world’s crude last year against 30% from the Middle East, and is filling part of the gap.

Brazil passed four million barrels a day this year and set a monthly production record in June. The Americas Society and Council of the Americas put its crude sales to China up 87% in the first five months.

Guyana, a country of about 800,000 people on South America’s north coast, has gained most in proportion. Its government raised its 2026 petroleum revenue forecast to about US$6.5 billion, more than double the budget figure.

Venezuela sold more than 1.25 million barrels a day in May, its best month in over seven years. Colombia’s Ecopetrol rose 1.28% on Friday to US$16.58 in New York, the only regional oil share to gain.

What to Watch

The first question is whether Washington sends a formal reply to the Iran seven-day Hormuz plan through the mediators. Trump rejected the plan in remarks to reporters, and Iran says its timetable stays available.

The second is the oil price, which has swung with each diplomatic signal and trades again late on Sunday. Brent lost about 2% on Friday on talk of a deal, having gained 3.4% the day before on talk of a wider war.

The third is what happens to the region’s fuel subsidies if prices stay high into 2027. Chile has already stopped paying, and other governments are weighing the same choice.

The fourth is Latin America’s own diplomatic position, which has hardened. Colombia severed relations with Iran this month over alleged links to armed groups, and Tehran called the accusation baseless.
