Hormuz Crisis Tracker — 2026-05-31 · Cycle 2 (Desktop Substrate)

War Day: 93 | Ceasefire Day: 55 | Cycle: C116 (C2 of 2026-05-31; C1 authored earlier today + desktop addendum)
Grok bridge: NO — Apple Notes timed out; latest HORMUZ X-PULSE confirmed stale per C1. Reduced web sweep (delta-only vs C1; ~5 hours elapsed).
Baseline: C115 / 2026-05-31 C1 (5-hour gap — incremental signal capture)

PROVENANCE NOTE (desktop C2, 2026-05-31 ~22:xx UTC): C1 was authored earlier today and re-verified by an additional desktop sweep with Section 13 Addendum. This C2 is a focused delta-only cycle capturing signals that emerged after the C1 sweep closed — primarily Trump's "no hurry" walkback, Iran's formal rejection of the blockade-end claim, the new IRGC blanket vetting order, IAEA's record HEU report, and clarifications on VLCC rates and UAE strike scope. C1 body remains authoritative for structural state; this file tracks what moved in the last several hours.

⚡ CRITICAL FLAGS THIS CYCLE


1. Conflict Status — Delta vs C1

War Day 93 / Ceasefire Day 55 (unchanged).

Key new developments since C1:


Ceasefire likelihood assessment vs C1: DOWNGRADED. C1 read the tentative MOU as "elevated probability, pending signature." C2 evidence — Trump's public "no hurry," Iran's formal rejection of the blockade-end claim, the IRGC blanket vetting order, the IAEA HEU report, and Iran's $12B precondition restated — collectively imply both sides are publicly hardening their positions over the weekend. The framework still exists, but the signature path narrowed. Watch Monday's market open.


2. Strait of Hormuz — Operational Delta vs C1

ParameterStatus C2Δ vs C1
Transits/day (May 31 trackers)~4 transits (straits.live) vs ~95/day pre-war normalCONFIRMED (still near floor)
Strait status (live tracker)CLOSED (straits.live); Hormuz Index 94 (extreme)CONFIRMED
US blockade — politicalEnded May 29 (Trump)CONFIRMED
US blockade — physicalContinued enforcement; ship disabled May 30CONFIRMED
Iran's stance on blockade-endFormally rejected (foreign ministry + state media)NEW
IRGC universal vettingBlanket order May 30 — all vessels need IRGC Navy pre-auth + designated routesNEW — TIGHTENING
Mine threatCRITICAL — May 30 Oman alert (suspected mine); US has not confirmed minesCONFIRMED
China/India exceptionsStill operational under bilateral mechanismsCONFIRMED
Pentagon postureAsserts safe passage despite mine presenceCONFIRMED
P&I re-entryNo re-entry — Day 55CONFIRMED
Key narrative: C1's central observation — that the blockade-end announcement runs ahead of physical normalization — was reinforced over the next 5 hours by Iran's formal rejection, the IRGC blanket vetting order, and the May 30 mine alert. Iran is consolidating transit control, not relaxing it. Physical transit count unchanged (~4/day).

3. Tanker Attack Log — Delta vs C1

Running total unchanged at ~83+ commercial incidents, 41+ UKMTO reports since Feb 28.

DateVessel/TargetFlag/OperatorLocationTypeDamageΔ

The major C2 correction is scope of UAE belligerency: not late-cycle only, but a campaign running from the first days of the war (per WSJ). Append-only log; prior entries preserved in C1 and earlier reports.

4. Oil Prices — Delta vs C1

Markets closed Friday May 29 at the levels C1 captured (Brent ~$91.2, WTI ~$87.7–93.9). Saturday/Sunday have no major futures session.

BenchmarkFriday May 29 CloseC2 NoteΔ vs C1
Brent$91.12Pre-Monday: weekend headlines lean hawkish (Trump "no hurry"; IAEA HEU report; Iran rejection) — Monday gap-up riskCONFIRMED
WTI~$87.7–93.9Same Monday gap-up riskCONFIRMED
Monthly move (May)−17% to −19% (biggest since 2020)CapturedCONFIRMED
Hormuz Index Crisis Pressure94 (extreme) — markets not pricing imminent resolutionNEW DATA POINTNEW
C2 price note: With weekend signal flow uniformly hawkish vs C1's read (Trump cooling, Iran rejecting, IAEA HEU stockpile record, IRGC blanket vetting), Monday Asia/Europe opens carry asymmetric upside risk for Brent. The $90–100 analyst band in C1 may be tested on the upside if the deal slips into a multi-week impasse. The Hormuz Index at 94 (extreme) confirms structural pricing has not moved despite the headline rally — the spot-vs-structure decoupling C1 flagged remains the defining tension.

5. Strategic Petroleum Reserves — Delta vs C1

No new IEA/national SPR announcements in the C2 window. State unchanged from C1:


SPR runway: unchanged at ~47 days nominal coverage; long exhausted on paper (Day 93). If Trump's "no hurry" stretches the impasse, the announcement-vs-physical-delivery gap reopens. STALE; no C2 movement.


6. Bypass Infrastructure — Delta vs C1

GAP: ~14–15 mb/d UNBRIDGEABLE — unchanged. Iraq's April production at 1,494 BBL/D/1K (down from 1,906 March) confirms recovery is fragile, not consolidated.

7. Maritime Insurance & Shipping — Delta vs C1

DFC backstop$40B revolving (Chubb lead)CONFIRMED
Lloyd's"Stands ready" — conditions absentCONFIRMED
Key C2 correction: VLCC rates are not at the $423K peak as C1 carried; they fell to ~$100K/day as Hormuz volumes collapsed 36% (Lloyd's List). The rate decline reflects volume destruction, not de-escalation — voyages are longer, ton-miles are altered, and the absence of P&I coverage continues to bottleneck commercial commitment.

Iran's "Hormuz Safe" scheme (surfaced more clearly this cycle) is the strongest signal yet that the insurance vacuum is being filled by state-backed alternatives — likely with limited acceptance by Western owners but operational for China/India bilateral exceptions and shadow-fleet flows.

P&I re-entry remains ABSENT — Day 55. Structural de-escalation indicator still has not fired.

12. Convergence Assessment

(a) What Changed This Cycle (C2 vs C1)

  1. Trump publicly cooled — "no hurry" [NEW — HIGH]. Friday Situation Room ended without decision; Saturday Fox interview airs with explicit "no hurry"; Saturday Trump requests MOU edits on nuclear material handling and Hormuz reopening. C1's "language points pending" reframed as a multi-week impasse risk.
  1. Iran formally rejected blockade-end claim [NEW]. Foreign ministry + state media both pushed back on Trump's May 29 framing. The political/physical gap C1 flagged is now also a narrative gap.
  1. IRGC blanket vetting order (May 30) [NEW — TIGHTENING]. Khatam al-Anbiya Central HQ requires all commercial vessels to use designated routes + obtain IRGC Navy pre-authorization. Iran consolidating transit control on the same weekend the deal was supposed to formalize.
  1. IAEA: record military-grade HEU stockpile (May 31) [NEW — HIGH]. IAEA report drops mid-negotiation, directly complicating the MOU's no-weapon pledge premise. Nuclear Lock 6 TIGHTENING; HEU disposal pushed into the 60-day talks track per C1 framework, now under harder light.
  1. UAE strike scope expanded — campaign since first days of war (WSJ) [NEW SCOPE]. Not just late-cycle Lavan/Sirri; targets include Qeshm, Abu Musa, Bandar Abbas, Lavan, Asaluyeh petrochemical. Saudi Arabia warned US in early April that UAE ops could trigger Iranian energy-infra retaliation. Iranian retaliation cumulative on UAE/Kuwait: 13 killed, 224 injured.
  1. VLCC rate clarification — ~$100K/day, not $423K [CORRECTION]. C1 carried the C88 $423K peak as STALE. Lloyd's List (May 2026) shows rates fell to ~$100K as Hormuz volumes collapsed 36%. The rate decline is volume-driven, not de-escalation-driven.
  1. Iran's "Hormuz Safe" state-backed insurance scheme surfaced more clearly [NEW]. Tehran filling the insurance vacuum left by P&I withdrawal — likely operational for China/India bilateral + shadow-fleet flows.
  1. Iraq April production 1,494 vs 1,906 March [NEW DATA]. Confirms recovery is fragile, not consolidated; bypass envelope holds at ~5–6 mb/d.

(b) Structural Locks Status — Delta vs C1

Lock 1 — Price [LOOSENING but with C2 reversal risk]. Brent $91.12 May 29 close holds; Monday open faces asymmetric upside risk on weekend hawkish signal flow. The May −17% to −19% gain may give back materially.

Lock 2 — Supply [HOLDING — was loosening in C1]. Iran's formal rejection of blockade-end + IRGC blanket vetting order means C1's "legal loosening" framing weakened. Transits still ~4/day; Iran consolidating control.

Lock 3 — Insurance [HOLDING]. P&I absent Day 55. No C2 movement. Iran's Hormuz Safe scheme is a workaround, not Western re-entry.

Lock 4 — Labor [HOLDING]. Unchanged — ~22,500 trapped.

Lock 5 — Duration [DOWNGRADED — was loosening in C1]. Trump's "no hurry" + Iran's $12B precondition restated + MOU edits requested = signature window slipped. C1's "single highest-leverage event" (Trump signature) now indefinite.

Lock 6 — Nuclear [TIGHTENING — was holding-by-deferral]. IAEA's record HEU report directly contradicts the MOU's no-weapon pledge premise; HEU disposal still deferred but under harder light.

Lock 7 — Geographic [TIGHTENING vs C1's "mixed"]. UAE covert campaign confirmed as longer-running than C1 captured; Saudi early-April warning reveals more belligerency than visible; Iranian retaliation on UAE/Kuwait has produced 13 killed cumulatively.

Lock 8 — Capability [HOLDING]. No US minesweepers; mine-clearance 6 months; new May 30 mine alert + IRGC vetting; Project Freedom paused.

Lock 9 — Dual Chokepoint [HOLDING]. Suez ~60% below normal; Houthi rerouting through 2027 baseline.

Lock 10 — Leadership [HOLDING — was loosening slowly]. Iranian factional contradiction widening (negotiators vs. state media + IRGC + Speaker Ghalibaf camp); blanket vetting + $12B precondition + formal blockade-end rejection mean the consolidation-side is winning the weekend.

Lock 11 — Energy Infra [TIGHTENING vs C1's "holding-worsened"]. WSJ confirms much broader UAE campaign on Iranian energy/petrochem infrastructure (Asaluyeh added). Ras Laffan timeline refined — North site near-term restart possible; South site end-summer; 17% capacity lost for years.

Tally C2: 1 loosening (Price, with reversal risk), 6 holding, 4 tightening (Supply, Duration, Nuclear, Geographic-Locks-7, Energy Infra). Net direction REVERSED vs C1: C1 was 4 loosening / 5 holding / 2 mixed-worsened; C2 is decisively toward tightening over the weekend.

(c) Critical Watch (Next Cycle)

(d) Net Assessment

C1 captured the apex of the diplomatic track: a tentative MOU, ended naval blockade, and the largest single-month oil-price decline since 2020. C2 captures the apex turning. Over a five-hour window the structural signals reversed direction across the locks that drive the system. Trump publicly cooled — "no hurry, I'd like to say I'm in a hurry, because gasoline prices are going to come tumbling down, but if you're going to be in a hurry, you're not going to make a good deal… if we don't get what we want, we're going to end it a different way" — and requested edits to the MOU on nuclear material handling and Hormuz reopening. Iran formally rejected the blockade-end framing through the foreign ministry and state media. The IRGC issued a blanket vetting order requiring all commercial vessels to use designated routes and obtain Navy pre-authorization — consolidating, not relaxing, transit control. The IAEA reported a record military-grade enriched uranium stockpile on the same day, dropping a hard fact into the MOU's no-weapon pledge premise. And the WSJ revealed the UAE covert strike campaign began in the first days of the war, with Saudi Arabia having privately warned Washington in early April that the operations risked exactly the kind of regional energy-infra retaliation that materialized.

The market does not yet know any of this is a reversal. Friday closed Brent at $91.12 on the C1 narrative; Monday opens on the C2 narrative. The asymmetry favors gap-up — but the structural picture (transits at ~4/day, P&I absent Day 55, GAP ~14–15 mb/d, Iran's Hormuz Safe scheme operational, VLCC volumes down 36%) was never priced into the May 17% decline. The price has room to retrace toward the structural reality without anything physical changing.

The off-ramp from C1 is still on the table — a written MOU exists, the framework is documented, and the ceasefire (however violated) has held 55 days. But the locks moved the wrong way this weekend. C1's "deal probability elevated, pending signature" reads as C2's "deal in indefinite limbo, four locks tightening, one reversing." The hard call: if Monday's open does not snap the price premium back at least partway, the market is mispricing the weekend. Watch the open; watch P&I; watch the IRGC vetting order's first enforcement action; watch whether Iran acknowledges or rejects the IAEA HEU finding. The next 72 hours are the test of whether the C1 framework holds or the locks resume their pre-deal pattern.
