Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.

Two separate scales from 1 to 10. Strature never multiplies or merges them.

What changed

Dated, newest first

  1. Grossi told the Security Council that Iran must give inspectors immediate access; about 440 kg of 60% uranium, the IAEA's estimate from before June 2025, unverified since June 2025; agenda adopted with 11 votes, Russia and China against, Pakistan and Somalia abstaining [12] [13] [5]
  2. Russia, China and Niger voted against; Council action unlikely; UN sanctions reimposed in 2025; Pezeshkian would accept verification within a deal [3]
  3. Rezaei (10 Sep) said IAEA actions could push countries to leave the NPT; officials and MPs called for withdrawal (28 Sep); Kremlin does not want Iran to leave (29 Sep) [4]
  4. Austria denied AEOI head Eslami entry for the IAEA General Conference: UN travel ban; the US objected in New York to the exemption Austria sought [6]
  5. UK told the Board: in the reporting period Iran gave no access to any nuclear facilities and blocked all in-field verification [2]
  6. GOV/2026/61 adopted 23-3-8; reports the findings of 12 Jun 2025 and 10 Jun 2026 and GOV/2026/50 to the Security Council and General Assembly; quarterly reports continue [1]
  7. About 440 kg of 60% uranium before June 2025, whereabouts unclear; nuclear sites hit in a war that began 28 Feb 2026 [5]

Why it matters

On 9 Sep 2026 the IAEA Board in Vienna voted 23 to 3, with 8 abstentions, to report Iran's safeguards non-compliance to the UN Security Council. The UK told the Board that Iran had given inspectors no access to any nuclear facility in the reporting period. Some Iranian MPs and former officials want Iran to leave the NPT; the President says Iran does not seek nuclear weapons and would accept inspectors inside a deal.

Why Likelihood 4 Pushes: report to the Security Council on 9 Sep 2026; no access; second war since 28 Feb 2026; MPs' call of 28 Sep. Brakes: President rules out weapons and offers verification in a deal; Russia opposes an exit; Russia and China shield Iran at the Council; Guardian Council must approve any law.

Why Impact 7 Threshold case a notice, effective three months later.

The other facts on file (4)
  • General Assembly elected Austria to the UN Security Council for 2027-2028, term from 1 Jan 2027 [7] (3 Jun 2026)
  • Majlis committee drafted an NPT withdrawal bill, not scheduled for a vote by 29 Sep 2025; Guardian Council review applies [8] (29 Sep 2025)
  • Article X: withdrawal on three months' notice to the parties and the Security Council [9] (1 Jul 1968)
  • Brent settled at $94 on 9 Mar 2026, up about 50% from the start of the year, as Hormuz shipments fell after the onset of military action [11] (Mar 2026)

How it spreads

If

Between 26 Oct 2026 and 25 Oct 2027, Iran gives formal notice of withdrawal from the Treaty on the Non-Proliferation of Nuclear Weapons under its Article X, to the other parties and the UN Security Council.

Not under way

Channels 5 on the card

  1. CanadaNo direct Canadian loss sourced.
  2. Nuclear rulesAn exit takes effect three months after notice [9]; inspections would end with it.
  3. War riskAn exit would strengthen the case for new US or Israeli strikes.
  4. Oil and shippingHigher risk of a second Hormuz closure (Strature's view).
  5. The UNThe Security Council, with Austria on it from 2027, would face a vote Russia and China can block [3][7].

Three scenarios and their signposts

  1. S1

    Frozen file

    No access, no exit; the Board keeps reporting each quarter.

  2. S2

    Deal and return

    Iran lets inspectors back inside a wider deal.

  3. S3

    Exit notice

    The Majlis passes the withdrawal bill and the Guardian Council approves it, or the leadership gives notice directly.

The signposts of each scenario
PathSignpost
S1The Director General's report before each regular quarterly Board meeting
S2An IAEA team returns to a struck site
S3The bill is put on the Majlis agenda

No probability is given for the three paths.

The other side

Iran's offer of verification within a deal leaves a path back. A return of inspectors would ease the risk to Gulf shipping, and Vienna would keep its role as the place where the file is handled.
