The US-Iran 14-Point Draft Memorandum of Understanding: Key Provisions
The United States and Iran have drafted a 14-point memorandum of understanding (MOU) to be formally signed on June 19, 2026, in Switzerland, establishing a framework to end hostilities that began on February 28, 2026, and initiating a 60-day window of final negotiations.
The draft MOU commits both sides to an immediate and permanent end to hostilities across all fronts — including Lebanon — and to refraining from any further hostile actions or threats of force against each other.
Immediately upon signing, the US agrees to lift its naval blockade of Iranian waters; full maritime traffic restoration through the Strait of Hormuz is expected within 30 days, along with US Treasury waivers permitting Iranian crude oil and petrochemical exports.
On nuclear matters, Iran reaffirms its commitment not to develop nuclear weapons; remaining points — including the duration of a moratorium on uranium enrichment and the disposal of existing enriched uranium stockpiles — are deferred to the 60-day final negotiation phase.
A $300 billion economic rehabilitation and reconstruction programme for Iran is pledged by the US and its regional partners, to be implemented upon completion of a final permanent agreement.
The Strait of Hormuz: A Critical Maritime Chokepoint
The Strait of Hormuz is a narrow waterway between the Arabian Peninsula and Iran connecting the Persian Gulf to the Gulf of Oman and the wider Indian Ocean. It is the world's single most important oil chokepoint by volume.
Reopening the Strait of Hormuz is a core deliverable of the MOU signed before any nuclear or sanctions issues are resolved, reflecting the strait's outsize importance to global energy and economic stability.
The Nuclear Non-Proliferation Treaty (NPT) and Iran's Obligations
The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) entered into force in 1970. It creates three categories of states: nuclear-weapon states (the P5), non-nuclear-weapon states (NNWS), and parties obligated to pursue disarmament. Iran is a signatory NNWS under the NPT.
The MOU's nuclear provisions require Iran to reaffirm its NPT commitment against weapons development; the contested 60-day negotiation will centre on operationalising this through a formal enrichment moratorium and enhanced IAEA inspections.
The JCPOA: Historical Precedent for Iran Nuclear Diplomacy
The Joint Comprehensive Plan of Action (JCPOA), concluded in July 2015 between Iran and the P5+1 (five permanent UN Security Council members plus Germany), was the most comprehensive nuclear deal ever reached with Iran.
The 2026 MOU attempts to construct a successor framework to the JCPOA. The core unresolved tension — the duration of an enrichment moratorium (US demands 20 years; Iran proposed 5–10 years) — directly mirrors the "sunset clause" debate of 2015 negotiations.
Memorandum of Understanding (MOU) in International Law
An MOU is a non-binding or quasi-binding instrument in international diplomacy, expressing an intent to cooperate or the terms of an agreement without the force of a formal treaty. In practice, it typically precedes a legally binding treaty and establishes the framework and timeline for further negotiation.
Key Details
- MOUs do not require ratification by national legislatures (unlike treaties); they carry political rather than strict legal weight
- The 2026 US-Iran MOU will be made binding through a subsequent UN Security Council resolution approving the final agreement
- Mediation in this case was conducted by Pakistan; venue agreed upon: Switzerland
- Multiple competing drafts circulated (at least three versions reported), indicating the depth of unresolved issues
The choice of an MOU rather than a full treaty reflects the diplomatic reality that too many details remain contested; the 60-day negotiating window is designed to convert the MOU's political commitments into enforceable obligations.

- Iranian frozen assets sought for immediate release: approximately $24 billion
- US naval blockade lift: immediately upon MOU signing
- Strait of Hormuz full maritime restoration timeline: within 30 days of signing
- Oil transiting Hormuz: approximately 15–17 mb/d (~20–27% of global supply)

- Weapons-grade threshold: 90% enriched uranium
