What does the U.S.-Iran agreement say? | Explained

What Happened

• On 17 June 2026, the US and Iran signed a 14-point Memorandum of Understanding (MoU) — referred to as the "Islamabad Memorandum" — ending their active military confrontation and establishing a framework for nuclear negotiations.
• The MoU provides a 60-day ceasefire and negotiation window, after which a comprehensive nuclear agreement is expected.
• Key provisions cover: nuclear enrichment and stockpile disposition, sanctions relief, frozen Iranian assets, maritime access through the Strait of Hormuz, and reconstruction funding.
• Israel has opposed the agreement, raising concerns about Iran retaining nuclear infrastructure; Israeli strikes on Lebanon continued even after the MoU was signed, threatening the nascent accord.

The Islamabad MoU — Key Provisions

The 14-point MoU is a framework agreement, not a legally binding treaty. Its main provisions:

Nuclear: - Iran agrees to suspend uranium enrichment for up to five years (while asserting its NPT right to enrich for civilian purposes on its own soil) - The disposition of Iran's existing stockpile of ~440.9 kg of 60%-enriched uranium to be decided within 60 days; the minimum methodology accepted is downblending on-site under IAEA supervision - Iran has not agreed to dismantle its nuclear infrastructure

Maritime and Security: - Reopening of the Strait of Hormuz to commercial shipping toll-free for 60 days - Lifting of the US naval blockade of Iranian ports - 60-day extension of the ceasefire (from the date of signing)

Sanctions and Economic: - The MoU calls for the complete elimination of all sanctions on Iran under a final agreement, including UN Security Council resolutions and all US primary and secondary sanctions - Up to $25 billion in frozen Iranian assets to be released contingent on future compliance - A fund of at least $300 billion for Iran's reconstruction and economic development, to be established with regional partners

Sanctions Architecture against Iran

Iran has faced a layered sanctions regime since the late 1970s. Three principal layers exist: (1) UN Security Council sanctions (imposed through multiple resolutions from 2006; reimposed via snapback on 27 September 2025 through UNSC Resolution 2231's mechanism); (2) US primary sanctions (covering direct US–Iran transactions, imposed under IEEPA — International Emergency Economic Powers Act, 1977); (3) US secondary sanctions (penalise third-country entities transacting with designated Iranian individuals, entities, or sectors — including oil, banking, and shipping). The MoU's promise of "complete elimination" of sanctions requires not just executive orders but, for UN sanctions relief, a new UNSC resolution — which Russia and China could support but would face complex geopolitical management.

Iran's Frozen Assets

Iran holds foreign-exchange reserves and oil revenues frozen in overseas accounts due to sanctions. Estimates of total frozen Iranian assets vary widely (commonly cited: $6–10 billion in accessible form; higher estimates of $25+ billion pending further compliance verification). A notable prior case: the 2023 US–Iran prisoner exchange was linked to the release of approximately $6 billion in Iranian funds held in South Korea (through a Qatari intermediary). The 2026 MoU references up to $25 billion in staged release contingent on compliance milestones — a significant escalation from 2023.

Israel's Opposition to the MoU

Israel is not a party to the NPT and has maintained a policy of nuclear ambiguity (neither confirming nor denying possession of nuclear weapons). Israel opposes any deal that leaves Iran with enrichment infrastructure, arguing that even a capped programme provides a latent breakout capability. Following the MoU signing on 17 June 2026, Israeli forces continued strikes on southern Lebanon (targeting Hezbollah, Iran's proxy), with French officials publicly calling on the US to pressure Israel to halt hostilities. Israel's opposition reflects three concerns: (1) Iran retaining enrichment know-how; (2) sanctions relief restoring Iranian economic power; (3) the deal implicitly legitimising Iran as a regional power.

The JCPOA Comparison

The 2026 MoU is structurally similar to but more modest in ambition than the 2015 JCPOA. The JCPOA required Iran to reduce its LEU stockpile to 300 kg and cap enrichment at 3.67% for 10–15 years; the 2026 MoU addresses an Iran with a far larger, more advanced programme. The MoU does not require dismantlement of centrifuges — a key JCPOA element — making it weaker on non-proliferation but more achievable as a first step after military confrontation. The "zero stockpiling" concept (Iran destroys or exports all enriched material, retaining no fissile stockpile) was reportedly considered but not adopted.
