According to US media, the mooted deal is not a final settlement – instead it leaves some of the thorniest issues to be negotiated later, including the scope and timing of Iranian sanctions relief, the release of frozen Iranian funds, and Washington’s demands for Iran to curb its nuclear ambitions.
“So we have, what I think is a pretty solid thing on the table in terms of their ability to open up the Straits,” he said referring to the Strait of Hormuz – the crucial waterway where 20% of the world’s oil and liquefied natural gas passes and which Iran has been blocking.
Oil prices fell sharply and Asian stock markets rose on Monday on hopes of an agreement.

Why and how is US blockading Iranian ports in Strait of Hormuz?
The reported deal has split Trump’s Republicans, with some publicly arguing it is too lenient on Iran.
Senator Ted Cruz said it would be “a disastrous mistake”, while Roger Wicker, who chairs the Senate Armed Services Committee, said a 60-day ceasefire would mean “everything accomplished by Operation Epic Fury would be for naught!”
Senator Lindsey Graham, who is a close Trump ally, also criticised any deal that would leave Iran perceived as being a dominant force in the region.
“It makes one wonder why the war started to begin with,” he said.
Trump responded by dismissing his critics as “losers” and saying “the deal with Iran will either be a great and meaningful one, or there will be no deal”.
Even in a best case scenario, the effects of a deal are unlikely to be seen right away.
It could be months before the shipping industry will be able to go back to supply chains that are “physically in the same shape as they were before the crisis”, Lars Jensen, chief executive of Vespucci Maritime and former director of shipping company Maersk, told BBC Radio 4’s Today programme.
Should a deal between Iran and the US be announced in the coming days, the industry would still remain “cautious and hesitant” to make any “major operational changes”, Jensen explained.
The US and Israel launched wide-ranging strikes on Iran on 28 February, sparking conflict across the Middle East. Iran responded by attacking Israel and US-allied states in the Gulf, and effectively closed the Strait of Hormuz. The move sent oil prices soaring globally.
Shortly after a ceasefire was agreed in early April, the US established a blockade of Iranian ports, which Trump says will remain “in full force and effect until an agreement is reached, certified, and signed”.
In Sunday’s post on Truth Social, Trump reiterated that Iran “must understand” it cannot develop a nuclear weapon. Tehran has repeatedly said its nuclear programme is solely for peaceful purposes.
Some reports in US media suggest the deal could see Iran agree to eventually hand over its highly enriched uranium.
At the start of the war, Iran is thought to have had about 440kg (970 lbs) of uranium that was enriched up to 60% purity – a short process away from being enriched further to the weapons-grade 90%, which theoretically could allow it to create a nuclear bomb.
In an update posted to Truth Social on Monday night, Trump said that the enriched uranium would either be “immediately” turned over to the US, or “preferably, in conjunction and coordination with the Islamic Republic of Iran, destroyed in place”.
Iranian President Masoud Pezeshkian told state TV Iran was ready “to assure the world that we are not after a nuclear weapon.”
