Iran's Three-Stage Negotiation Formula: What Tehran Wants, What It Won't Discuss, and Why the Strait of Hormuz Is the Leverage Point
Iran has handed mediators a three-stage framework for negotiations with the United States, beginning with a full ceasefire and the formal termination of the current conflict — but explicitly excluding its nuclear programme and control of the Strait of Hormuz from the opening agenda, according to reporting by Al Jazeera and confirmed by Euronews citing the pan-Arab outlet Al Mayadeen.
The proposal, conveyed to Washington through Omani intermediaries, represents Tehran's most substantive diplomatic outreach in months. Oman, which has maintained discreet channels with both Washington and Tehran for years, has publicly urged all parties to pursue diplomacy as the primary means of securing freedom of navigation through the Strait of Hormuz — the world's most critical oil transit chokepoint, through which roughly a fifth of global oil shipments pass.
The structure of the proposal, as described across multiple regional outlets, suggests Iran is willing to negotiate the contours of the war's termination first — before any discussion of the programme that Western powers say could produce a nuclear weapon, and before any negotiation over the military posture that gives Iran de facto control of the strait's southern shipping lane.
What happens next will test whether the framework represents a genuine diplomatic opening or a stalling tactic designed to relieve pressure while the conflict continues on terms favourable to Tehran.
What the Three-Stage Formula Actually Proposes
The first stage, according to the framework as reported by Al Mayadeen and relayed by Euronews on 26 April 2026, centres on a complete cessation of hostilities and the formal conclusion of the war — language that implies not merely a ceasefire but a political settlement that ends the state of conflict between the parties involved. Iran, through its intermediaries, has insisted this stage must result in what it describes as guarantees against resumed hostilities.
The second stage would presumably address the sanctions architecture that has strangled Iran's economy since the reimposition of sweeping US measures following the withdrawal from the Joint Comprehensive Plan of Action in 2018. Whether the formula envisions a sequential lifting of restrictions or a comprehensive package contingent on full compliance remains unclear from the available reporting.
The third stage, based on the structure described in regional media, appears to concern broader normalisation — diplomatic relations, potential prisoner exchanges, and the resumption of normal commercial and diplomatic activity between Iran and the parties currently arrayed against it.
What is explicitly absent from the opening position, and what Al Jazeera reported on 27 April 2026 as a red line Tehran has communicated to mediators, is any discussion of the nuclear programme or the Strait of Hormuz. Iran is telling the intermediaries that neither topic is on the table until the war is permanently concluded.
That bracketing is significant. The nuclear programme and Hormuz control are the two instruments most frequently cited by Western and regional analysts as Iran's primary sources of leverage in any negotiation. By making them conditional on a prior political settlement, Tehran is essentially saying it will not negotiate its most potent cards until it has extracted maximum concessions on the ceasefire itself.
Why Iran Is Willing to Talk Now
The timing of the proposal requires context. Iran's economy has faced sustained pressure from sanctions, and the conflict — whatever its broader trajectory — has imposed costs across the region. But the more compelling structural reason may be domestic: a negotiated end to the war, if it produces a settlement that Iran can frame as a political rather than a military outcome, is more politically sustainable than either a continued stalemate or a battlefield reversal.
Iran's leadership has consistently distinguished between the conflict itself and the longer-term structural confrontation with Western-backed regional architectures. The three-stage formula, if it represents Tehran's actual position, reflects that distinction: Iran wants to end the shooting war on terms it can present domestically as a political victory, without surrendering the leverage it has built over the nuclear and Hormuz dossiers.
Oman's role as the transmitting intermediary is not incidental. Muscat has maintained working relationships with Washington, Tehran, and the broader regional actors involved in the conflict. The sultanate's foreign ministry publicly signalled on 26 April 2026 that it views diplomacy as the only credible path to securing the Strait of Hormuz — language that amounts to an endorsement of the negotiation track, however imperfect the prospects.
The question is whether Washington's appetite for a phased approach matches Tehran's sequencing. The United States and its partners have consistently demanded that any negotiation address the nuclear programme as a non-negotiable condition — not a prize to be handed over after the war ends but a baseline requirement before any broader deal can be considered.
The Hormuz Chokepoint and the Structural Stakes
The Strait of Hormuz is the geopolitical reason this negotiation, however tenuous, matters beyond the bilateral relationship between Washington and Tehran. Roughly 20 to 25 percent of the world's oil supply transits the strait daily, according to Energy Information Administration data. Any disruption — whether from military posture, mining, or harassment — reverberates immediately through global energy markets.
Iran controls the strait's northern approach through its geographic position and its network of coastal military infrastructure. This is not disputed by analysts across the political spectrum: the Islamic Revolutionary Guard Corps Navy operates small-craft and missile systems along the northern shore that give Iran a layered denial capability in the waterway. The same capability makes Hormuz central to any negotiation about regional security architecture.
By bracketing Hormuz from the opening stage of the formula, Iran is effectively saying it will not negotiate the terms of the strait's status — which effectively means it will not negotiate the military posture that gives it that control — until the war is over. That is a significant hold on leverage. Whether the United States finds that position acceptable or believes it can extract Hormuz concessions through pressure is the central strategic question the administration faces.
The broader structural picture also includes the regional security architecture: the relationships between Iran, the various armed groups it supports, and the US-backed regional coalition that has been engaged in the conflict. Any ceasefire that holds will need to address the disposition of those forces. The nuclear programme sits inside that architecture — it is not a standalone technical issue but a function of how Iran positions itself within the regional security order.
Tehran knows this. The sequencing in its formula reflects an understanding that Washington wants to deal with the weapons question first, and a recognition that conceding that sequencing would surrender the leverage Iran has spent years building.
What Comes Next and Why Uncertainty Persists
The proposal is real in the sense that it has been transmitted through official channels and reported by credible regional outlets. But the gap between a transmitted formula and an agreed framework is wide, and the history of US-Iran negotiations is littered with proposals that reached mediators and never advanced.
Several variables will determine whether this round produces anything different. The first is whether Washington responds in a manner that Tehran finds acceptable — whether it engages with the three-stage structure or rejects the sequencing as a non-starter. The second is whether the ceasefire conditions Iran is insisting on are compatible with what the parties currently fighting describe as their minimum objectives. The third is whether any agreement reached on the first stage — if one is reached — holds long enough to generate momentum toward the second and third.
Oman will continue to serve as the primary conduit, which gives the sultanate unusual diplomatic leverage for a state of its size. Middle East Eye reported on 26 April that Muscat is actively urging all parties toward the negotiating table, with the Hormuz navigation question serving as the sultanate's explicit rationale for engagement.
The picture remains fluid. Iran has made an offer; Washington has not yet formally responded; the other parties to the conflict have their own positions and red lines. What the sources make clear is that a back-channel exists, that it is active, and that the topic of Hormuz is — as it has been in every US-Iran confrontation since 1979 — inseparable from the broader negotiation.
Desk note: Wire coverage of the Iran negotiation formula focused heavily on the three-stage structure and the ceasefire-first sequencing. Monexus drew from the same regional reporting but foregrounded the Hormuz bracketing — the element of the formula that most directly affects global energy markets and that reveals the most about how Tehran is sequencing its leverage. The Omani diplomatic role received less attention in the wire than its centrality to the back-channel warrants.
