Chaos Pulse 61/100: daily report, 5 October 2026

CHAOS PULSE: 61/100 — severe crisis (lower edge of the band)
Change: 0 since the initial assessment (5 Oct, 11:50 UTC); weekly change not computed yet (series started today).
Direction: no significant change.
Confidence: medium. Uncertainty band 55–66 (weighted sum of component ranges); widest component: energy (62–76).
Why: nothing in the twelve hours since the initial report changed the underlying state. Tanker attacks in Hormuz became more frequent (at least seven on 1–5 October), but Gulf crude exports remain near pre-war levels. Whether the East–West pipeline stopped after the strike on the Khurais pumping station is still disputed: one AFP source says it halted, Reuters and Bloomberg sources say it is flowing.

Scores are the author's judgement against fixed anchors (method v1, unchanged). Checks: daily report at 23:15 UTC (Mon–Sat), weekly on Sunday, plus four web monitors checked hourly. This is not continuous watching.

CP = 0.30×68 + 0.25×70 + 0.20×50 + 0.15×45 + 0.10×60 = 60.65 → 61. Band: 54.6 → 55 to 66.3 → 66.

What would lower the index (checklist): a US–Iran deal or a Yemen truce: no. Inventories stop falling and Hormuz really reopens: no (no stock data until the IEA report around 15 Oct; attacks increased). IMF WEO shows no contagion: pending. Taiz relieved: no. A date for trilateral Ukraine talks: no.

Signals

67 indicators collected on 5 Oct, 22:30 UTC; none anomalous. Hormuz transits (IMF PortWatch, 7-day to 27 Sep) 3.1 ships/day, at the wartime baseline; the data lag 8 days and miss ships with AIS off. Satellite fire detections near Russian refineries fell to 2.3/day vs 4.4 baseline; that is not evidence of fewer strikes (clouds, satellite passes) and sits awkwardly next to Ukraine's 51% claim. Gulf detections are at baseline: no thermal trace of a large new fire, a weak point against heavy damage at Khurais. Public anxiety readership (nuclear war, WWIII, shelters) is at or below baseline. None of these moves a score on its own.

Main finding

The day did not change the state. In energy two opposite forces balanced: more attacks in the strait, yet as much oil leaving the region as before the war, largely by bypass routes (about 40% of Gulf crude avoided Hormuz in September vs 17% pre-war, per Kpler via Al Jazeera, 5 Oct¹). So the key risk is the bypasses themselves: a confirmed halt of the East–West pipeline would be a major supply disruption and an unscheduled alert. For now the weight of sources says it is flowing.

New events

• Hormuz, 5 Oct, ~16:37 UTC: a tanker hit by an unknown projectile off Musandam, engine-room fire, crew safe (UKMTO, reported by Reuters via Dawn, 5 Oct²; Arab Times, 5 Oct³). At least seven tanker attacks on 1–5 Oct (Shafaq News, 5 Oct⁴); delayed UKMTO reports make the exact count uncertain (gCaptain, 5 Oct⁵). A continuation of the regime, not a new state.
• US build-up: about 9,000 troops and a third carrier group heading to the Middle East by late October (AP, 1 Oct⁶). Preparing for war is not a decision to start one; no score change.
• Iran: reviewing the US reply via mediators; its spokesman says the reply is about the nuclear file while Tehran is focused on Hormuz (AFP via Malay Mail, 5 Oct⁷).
• Russia–Ukraine fuel war: Ukraine's Defence Ministry claims 51% of Russian refining capacity is out of action; a claim by a party, not independently verified (AP, 5 Oct⁸). The Kremlin says Ukraine will "pay the price" (Newsquawk, 5 Oct⁹). 205 Russian drones overnight into 5 Oct, 172 downed (Ukrainian Air Force via AP).
• China again restricts exports of diesel, jet fuel and gasoline (NYT, 2 Oct¹⁰): an independent cause tightening the same diesel market the G7 is trying to ease.
• Not confirmed: Tasnim (5 Oct) reports a new missile attack from Yemen and suspended flights at Riyadh airport; only Iranian outlets carry it. Not counted.

Links and hypotheses

The chain "Hormuz → bypasses → strikes on bypasses" holds: Iran hits tankers in the strait, the Houthis hit the land bypass. Timing coincides, but there is no evidence of Iran–Houthi coordination on this pair of strikes (H1, common architecture, not supported). The mirror fuel war between Russia and Ukraine, with both sides openly naming economic damage as the goal, supports H2 (deliberate escalation). China protecting its own fuel market supports H6 (independent causes coupled by markets). Trump tying possible strikes to the election calendar suggests domestic politics sets military timing; it is not proof of "using the crisis" (H3).

Risk of a wider war

Unchanged. Triggers to watch: renewed US strikes on Iran (a third carrier group arrives by late October); a confirmed East–West halt coinciding with Hormuz attacks, so that the strait and its bypasses fail together; a Russian response to refinery strikes that touches NATO states (drones in Moldova are the precedent). No direct clash of major powers.

Signs of de-escalation

Middle East crude exports above pre-war levels on four of seven days in late September (Kpler); Iraq moved a VLCC through Hormuz for the first time in decades; Brent eased from $114 to about $100–103; the US–Iran channel remains open; no Iranian strike on a neighbouring state for 30 days (GlobalSecurity daily summary, a secondary aggregator).

Corrections

The attack on the Kuwaiti VLCC Kazimah III happened on 1 October (Seatrade, published 2 Oct), not 3 October as a monitor note said. Open discrepancy: Shafaq News names the vessel hit on 5 Oct as LIPSI, which my ledger records as hit on 4 Oct; not changed without a second source.

What to check next

East–West pipeline: still unresolved. AFP (one industry source, 5 Oct 08:44 UTC) says "big damage and the pipeline stopped again"; Reuters and Bloomberg sources say flows were not interrupted. No Aramco or ministry statement yet. Next check by 8 Oct: Yanbu loadings (Kpler, TankerTrackers). Also: the attack count in Hormuz against PortWatch; Iran's final reply to the US (by 12 Oct); an independent check of the 51% refining claim (by 12 Oct); the scope and length of China's fuel export curbs (by 15 Oct); Taiz and its supply road (by 10 Oct).
