Washington's patience is at an end. Teherans new leadership is in a power vacuum. And $100 oil is draining the world economy by the day. What's going on under the diplomatic smokescreen.

This Tuesday moment could easily be lost in the shuffle of the news cycle that’s constantly churning through Washington, but it's worth more than it's receiving. Secretary of State Marco Rubio appeared before the Senate Foreign Relations Committee and offered a statement that, given the last three months, is truly amazing: Iran now says it is willing to discuss nuclear issues that it refused, even weeks ago.

They've agreed to negotiate aspects of their nuclear program that they wouldn't even touch a month ago, a year ago,” Rubio told lawmakers. He did not go so far to declare it a breakthrough. He cautioned that it is "not a guarantee" that it will ultimately result in a deal that's acceptable. Yet this cautious language represents a real change in the nature of the game at least the one that Tehran can now play.

That's of critical importance because the world is suffering a harsh penalty for each day this war continues.

The unwanted war and the economic rubble that it left behind.

Order of events is relevant here. In February 2026, a series of targeted strikes, both US and Israeli, on the Iranian nuclear and military infrastructure triggered a domino effect that the world economy is still feeling. Ali Khamenei, one of the biggest casualties of the strikes, has been reported dead, leaving Iran in a succession crisis not seen before, with over 40 officials being killed in a single strike. His successor is his son, Mojtaba Khamenei, who, as the International Crisis Group observed, isn't quite supreme as his father was and whose legitimacy is limited in a system based on factionalism.

Iran's response was to shut down the Strait of Hormuz. That move, which blocked some 21 kilometres of water between Oman and Iran, led to what the IEA has called "the largest supply disruption in the history of the global oil market. The price of crude oil hit $120 per barrel, and an anticipated oil supply surplus in 2026 became a global scramble for oil alternatives. Because of the size of the disruptions, energy executives have cautioned that complete return to normal levels of oil supply from the Middle East will take until 2027.

For the average citizen, this meant trouble at the pump. The average pump price in the U.S. increased approximately $1.50 per gallon over pre-war prices. The disruption was even more pronounced in Asia, where over 80 percent of crude oil and natural gas transiting through the Strait of Hormuz would go to markets such as China, India, Japan and South Korea. The model of the GCC economy, which relies on unrestricted energy exports, was essentially collapsing. Limited other shipping routes in Saudi Arabia and the UAE. All the rest were in the open.

This is the economic scenario in which the ongoing diplomacy is played out. There's real skin in the game. It may not be mentioned, but every week without a deal impacts the global economy, and particularly negatively on developing countries, as the IEA's Fatih Birol made clear, saying that developing Asian and African countries will experience the "biggest pain of this crisis.

What is and isn't on the table

The US position, as Rubio spelled out, is clear enough. Iran must be willing to discuss strict and lasting reductions in, and even the cancellation of, enrichment. No initial deal, no sanctions lifted or Iran's assets unfrozen that would be after Iran has fulfilled "verified commitments," the administration said. Trump, for his part, has outlined two points: Iran can't be allowed to ever develop nuclear weapons and the Strait of Hormuz must be reopened.

Rubio was especially forthright with lawmakers on Hormuz. They should make it quite clear that ‘The straits are now open, we are not collecting any toll we will help clear the mines put there by them and they will not shoot at any ship,' he said.

Until recently, Iran's initial stance was that enrichment was an inalienable sovereign right as it could never be negotiated. There's some cracking on that wall. A draft memorandum of understanding is reportedly signed by Iranians that contains their promise to never pursue nuclear weapons and to negotiate about a suspension of enrichment, plus verbal promises through mediators about the extent of concession Iran is willing to make. Iran's atomic energy chief earlier suggested Tehran was ready to cut the concentration of its fuel to 60 percent-less-enriched uranium, a level just short of weapons grade, but would do so only if all sanctions were removed.

Washington's view is that those conditions are regressive. Sanctions relief is contingent on concessions. Iran has always wished for the opposite. That's the biggest hurdle that stands in the way of any deal.

It is hard to find someone to take the lead

Behind the diplomatic dance lies a more fundamental issue. On Tuesday, Rubio told senators there are indications Khamenei is becoming more involved in the affairs of the country, hinting that until recently, nobody in Washington was quite certain who they were dealing with or whether the person sitting across the table from them had the power to bind them to anything.

Unlike his father, Iran's new supreme leader is not supreme; there are several power centres, some of which overlap in authority, and factionalism is endemic to the system. Although President Masoud Pezeshkian has publicly insisted that no decisions can be made without the supreme leader's approval, that very message is indicative of the fragility.

Tehran has not contacted the U.S. in the past several days and is still examining the latest U.S. proposal, Iran's semi-official Mehr news agency reported, which emphasized Iran is approaching the issue in a "stern" manner in light of what it considers U.S. violations of the ceasefire. Meanwhile, Iranian state media said negotiations had come to a complete halt, a claim that sparked sharp criticism from Trump. Trump stated in a social media post that he and Iran had been in “constant communications” with each other, and that “where it leads, one never knows, but as I said to Iran, 'It's time.

Eerie dance this negotiation: the two sides playing their home base, yet also not wanting to be branded as the loser.

The world's secret to structure.

The JCPOA (2015 nuclear deal negotiated under Barack Obama) was not a failure to contain Iran in 2015, but was the unilateral withdrawal of the U.S. in 2018. Even with the most severe sanctions regime that Iran faced, Tehran was able to make strides in expanding its nuclear expertise and build significant enriched uranium stockpiles in the years since the withdrawal from the programme. When they exercised their military options in 2025, the situation was even worse than it would have been if the original deal had been kept.

Given that, there is a strong case that transcends geopolitical considerations, that any agreement that lacks firm verification in place and does not have bipartisan political security in the United States is at best provisional. However, the IAEA has not been able to resume inspections in Iran since June 2025's strikes and the IAEA chief, Rafael Grossi, has stated that any agreement without such inspections would be an "illusion of an agreement.

This caution should not be mistaken for bureaucratic caution. That's the root of the issue. A nuclear deal that can't be verified is not a nuclear deal at all, but a ceasefire with a diplomatic stamp on it.

The market's opinion of the value of something.

The oil markets are functioning as they should, speculating on an event before it actually happens. Trump, for his part, has issued mixed signals on the prospects of a permanent halt to the conflict, and in a single session, oil prices plunged more than 5 percent as traders have been closely attuned to every diplomatic signal issued from Washington or Tehran. Despite the recent price dip on deal hopes, Brent is still more than a third up on it pre-war levels at around $98 per barrel, as of early June.

The price difference between $71, where Brent was trading prior to the war and where it is now isn't merely a number. That spread amounts to a multi-trillion dollar annual income shift from energy-consuming economies to energy-producing economies, and it's a tax on growth that hurts those economies most who can least afford it.

If an agreement is reached to open the Strait, energy markets are likely to stay fragile for months as shipping insurance costs have been raised, route diversions are woven into supply chains and the confidence premium that ensures the free passage of tankers through contested waters is only slowly rebuilt once it has been broken down.

Where this truly leads to

The truth is no one can say for sure. Rubio's framing is “There is the prospect before us, which could happen today, it could happen tomorrow, it could happen next week” and it's a genuine uncertainty, even as he tries to sound cautious and optimistic. The fundamentals are simultaneously bullish and bearish.

Regardless of the economic tensions among the leadership, Iran has an economic reason to deal. But the war has made even worse all the country's structural weaknesses, and the economy was already in trouble before the conflict due to domestic protests and sanctions. Meanwhile, any leader who's seen to be surrendering Iran's nuclear programme out of necessity under military pressure faces the danger of being outflanked at home by hardliners who say that capitulating under pressure "sets a precedent for ever.

Washington, on its part, has leverage which it lacked a year ago. It's also made the world economy more vulnerable to the more that standoffs extend, the more damage they cause, and the more pressure they put on the US administration to produce results.

This time, if there is a difference, Iran doesn't seem to be the same regarding what it is willing to discuss. Is it a real strategic change or a tactical move to get some breathing space? Verification real, intrusive and sustained verification would tell us. But at this time, all headlines about progress should be interpreted as a sign in a fog, and not a destination. It's too late for the world to wait to see which it is.
