Iran separates Hormuz talks from nuclear concessions, narrowing ceasefire path

Iran is drawing a firm line between maritime de-escalation in the Strait of Hormuz and concessions on its nuclear program, signaling it may bargain over shipping access, sanctions relief and regional ceasefire steps without giving ground on enrichment.

A senior Iranian official told Reuters on September 25 that Tehran would show no flexibility on its nuclear program even if Washington accepted Iran’s proposal to reopen the Strait of Hormuz. The official said the waterway would remain closed until all of Iran’s conditions were met, including an end to the U.S. naval blockade of Iranian ports, the release of frozen funds and waivers on oil sanctions.³

The position narrows the space for a broader settlement by separating the most immediate economic and military pressure point — Hormuz — from the nuclear issue Washington says must be addressed in any durable deal. Iran’s proposal, outlined by Foreign Minister Abbas Araghchi at the United Nations, would reopen the strait within seven days if the United States accepted Tehran’s conditions, with nuclear talks resuming only afterward.⁵

That sequencing is now the central diplomatic dispute. Tehran wants maritime access, sanctions relief and ceasefire steps first. Washington wants Iran’s nuclear program folded into the same package from the start.⁵ For ceasefire diplomacy across Lebanon, the Gulf and the wider Iran war, the difference matters: a Hormuz-first deal could reduce immediate risks to energy shipping and regional escalation, but leave the nuclear confrontation unresolved.

A maritime track, not a nuclear deal

Under the Iranian plan, the United States would lift its naval blockade of Iranian ports, waive sanctions on Iranian oil sales, release about $12 billion in frozen Iranian assets and observe a regional ceasefire that includes Lebanon and Yemen. In return, Iran would reopen the Strait of Hormuz, a route that carried about one-fifth of the world’s traded oil and gas before the war.⁶

Araghchi has framed the proposal as ready for implementation once Washington agrees. Al Jazeera reported that Tehran says nuclear talks would begin only after the strait reopens at the end of the seven-day sequence.⁶ Analysts cited by Al Jazeera described the formula as a compressed version of an earlier June understanding: open Hormuz first, then move to the nuclear file.⁵

Reuters’ report added a harder edge: even if that sequence begins, Iran would not concede on what it describes as its nuclear rights, including uranium enrichment or shipping highly enriched uranium out of the country, a key U.S. demand.³

That means a Hormuz deal would likely be a de-escalation mechanism, not a comprehensive settlement. It could reduce pressure on shipping lanes and oil markets, but would not necessarily address U.S., Israeli and European concerns over Iran’s enrichment program.

Why the split matters for Lebanon and the Gulf

Iran’s proposal links maritime relief to a ceasefire “on all fronts,” including Lebanon, while also placing Yemen and the Gulf shipping lanes inside the same diplomatic frame.³⁶ That creates a tactical opening for mediators: a limited bargain could ease simultaneous flashpoints without requiring an immediate nuclear compromise.

But it also gives each side different incentives. For Iran, Hormuz is its main source of leverage after months of war and economic pressure. For Washington, reopening the strait without nuclear concessions risks appearing to reward Tehran for using a global energy chokepoint as bargaining power.⁹

The regional stakes extend beyond U.S.-Iran talks. France is working on a draft U.N. Security Council resolution backing freedom of navigation in the Strait of Hormuz, while Houthi attacks on Saudi Arabia and commercial shipping in the Red Sea and Bab el-Mandeb Strait have widened the maritime-security agenda.⁷ That makes Hormuz part of a broader Gulf and Red Sea crisis, not just a bilateral U.S.-Iran standoff.

Domestic politics limit Tehran’s room

Iranian domestic politics are also constraining nuclear flexibility. President Masoud Pezeshkian has suggested Iran could reduce enrichment levels, dilute its 60% uranium stockpile and allow international verification, according to Iran International.¹ But hardline figures reacted sharply, underscoring how politically costly nuclear concessions remain inside Tehran.¹

Iran International separately noted the distinction between Pezeshkian’s comments on the existing 60% stockpile and the senior official’s broader refusal to concede on the nuclear program.⁹ That difference allows Tehran to keep a narrow technical option open while rejecting a wider rollback of enrichment rights.

The backlash has also reached Araghchi. Hardliners criticized his presentation of the Hormuz plan through intermediaries, and Iran International reported that the foreign minister faced sustained attacks after putting forward the phased process.¹ The pressure reinforces why Tehran may prefer to negotiate over sanctions, shipping and ceasefire sequencing while holding a tougher public line on enrichment.

Washington’s rejection would shrink the opening

The diplomatic window may already be narrowing. Iran International, citing the Wall Street Journal, reported September 26 that President Donald Trump had rejected Iran’s seven-day ceasefire proposal and expected renewed strikes after the November midterm elections.² The report said the proposal would have reopened Hormuz and resumed nuclear talks in exchange for lifting the blockade on Iranian ports.²

If Washington insists on bundling Hormuz and the nuclear file, and Tehran insists on separating them, mediators will be left trying to bridge both the substance of a deal and the order in which each side gives up leverage.

For now, Tehran’s message is that maritime de-escalation is negotiable, but enrichment is not. That may keep open a path to a limited ceasefire in the Gulf, Lebanon and Yemen — while making a broader U.S.-Iran settlement harder to reach.
