240 Ships Stuck at Sea as US-Iran Nuclear Talks Stall Over Enriched Uranium

Iranian state television reported on Saturday that 240 commercial ships were stranded outside the Strait of Hormuz, unable to pass one of the world's most critical chokepoints for oil and LNG shipments. The backlog arrived as talks in Oman between American and Iranian diplomats entered what officials on both sides described as a decisive phase — yet one reportedly hampered by fundamental disagreement over the fate of Iran's enriched uranium stockpile.

A senior Iranian official told Reuters that Tehran has not agreed to hand over the material, directly contradicting what US negotiators had signalled was a near-final condition for lifting economic sanctions. The disclosure injected fresh uncertainty into efforts to prevent a collapse of the diplomatic process that observers say carries consequences well beyond the nuclear file.

The uranium sticking point

The stockpiles themselves are not new. Iran's programme has been the central concern of international inspectors since 2006, and the JCPOA — the 2015 deal that constrained it — unraveled following the US withdrawal under the Trump administration in 2018. What has changed is scale. International Atomic Energy Agency reporting has consistently documented that Iran now holds enough material at near-weapons grade to compress the time needed to build a device, regardless of intent. Western capitals, and Israel in particular, have treated this as a red line.

The senior Iranian official speaking to Reuters gave no indication that that red line had moved. "Iran has not agreed to hand over its highly enriched uranium stockpile," the official said, according to the wire service. That statement alone, if accurate, suggests the talks remain several steps from any agreed framework — contrary to some optimistic readings circulated in Washington late last week.

US officials have thus far declined to confirm or deny specific elements of the negotiating position. The State Department said only that discussions were ongoing and that no final agreement had been reached.

Hormuz as leverage

The 240-ship backlog provides a second dimension to the negotiating pressure. Iranian state media reported the figure on Saturday via the Al Alam Arabic news channel, without specifying when the queue began or whether it was the result of an active slowdown ordered by Tehran or simply the consequence of heightened commercial caution.

The Strait of Hormuz handles roughly 20 to 25 percent of global oil trade and a comparable share of LNG shipments. Previous periods of heightened tension — in 2019 and again in 2022 — produced visible disruptions to tanker traffic and brief price spikes, though the market impact was contained by strategic reserves and alternative routing. A prolonged bottleneck would be structurally harder to absorb in the current environment, where OPEC+ spare capacity is thin and inventory buffers have been drawn down.

It is not clear whether the shipping delay is a deliberate signal from Tehran or an organic consequence of insurers and operators exercising caution. Iranian officials have not commented publicly on the queue. But in a negotiating context where both sides are searching for leverage, the visual of hundreds of vessels idling in Gulf waters is itself a form of pressure — on energy markets, on allied governments, and on Washington, where a failed deal carries a political cost ahead of midterm calculations.

What a deal would actually require

Axios, citing reporting by Barak Ravid, laid out what it described as the parameters of a draft memorandum of understanding under discussion between the two sides. The terms reportedly include a 60-day extension of an existing ceasefire between the United States and Iran, the reopening of the Strait of Hormuz with no transit tolls imposed on commercial traffic, and the lifting of the US naval blockade — which has effectively constrained Iranian oil sales and pressured its banking sector since 2018.

Those terms, if accurate, represent a significant package of concessions from Washington. The naval blockade is not merely a symbolic measure: it is the primary mechanism by which the United States enforces secondary sanctions on third-country buyers of Iranian crude. Removing it would effectively legitimise what Iran has been doing informally through a shadow market — selling oil at a discount to buyers in China, India, and Turkey who have been willing to accept the reputational and legal exposure.

For Iran, the question is whether what is on the table is worth the price. Surrendering the enriched uranium stockpile would relinquish a geopolitical asset that has taken years and considerable national investment to build. It would also require a degree of international inspection that the Iranian government has historically resisted as an infringement on sovereignty. Axios's reported terms do not include any commitment on Iran's part to dismantle its enrichment infrastructure — only to restrict the use of material already produced.

That distinction matters. Weapons-capable infrastructure remains intact under the framework reportedly under discussion. What would be surrendered is the finished inventory — a supply of fissile material, not the capacity to produce more.

Wider consequences if the talks fail

The regional context is strained in ways that go beyond the nuclear file. Saudi Arabia and the UAE have both signalled concern about an uncontrolled Iranian nuclear programme but have also pursued their own diplomatic tracks with Tehran — including Chinese-mediated normalisation talks with Riyadh. European capitals, still invested in the JCPOA's architecture, face pressure from an American ally that views the deal as insufficient and an Iranian counterpart that views it as already violated. Israel's government has issued repeated private and public warnings that a deal it considers inadequate will not go unanswered, though Israeli officials have not specified what form any response would take.

The talks in Oman are described by people familiar with the process as genuine — not a performative exercise designed to buy time. That makes the uranium question more consequential, not less. A breakdown at this stage would likely produce renewed sanctions escalation from Washington, further pressure on the remaining parties to the JCPOA to activate snapback mechanisms, and an intensification of Israeli intelligence and military activity in the region. The Hormuz shipping queue, in that scenario, would not disperse.

What remains genuinely unclear is whether the senior Iranian official quoted by Reuters was speaking with the authority of the negotiating team or as a faction within a government that has historically shown deep internal divisions over how far to push confrontation with the West. Iranian politics on this question is not monolithic. The hardliners who benefited from the 2018 US withdrawal have influence; the pragmatists who would prefer sanctions relief do as well. The sources do not resolve that tension.

Neither, for now, does the Strait of Hormuz.

This publication covered the shipping backlog as the primary entry point into the talks — a structural lever rather than the technical nuclear question — which differs from wire coverage that led with the enrichment terms. The Reuters piece on the uranium standoff was treated as a corroborating disclosure rather than the lead fact. Monexus will continue to track the Oman negotiating track as it develops.
