Chaos Pulse 61/100: daily report, 6 October 2026

CHAOS PULSE: 61/100 — severe crisis (lower edge of the band)
Change: 0 since the previous report (5 Oct, 23:30 UTC); weekly change not computed yet (series started 5 Oct).
Direction: no significant change overall; inside it, the military component worsened while energy uncertainty narrowed.
Confidence: medium. Uncertainty band 56–66 (weighted sum of component ranges); widest components: energy (64–74) and military (66–74).
Why: the war is widening geographically. Drones sank a merchant ship in the exclusive economic zone of Bulgaria, a NATO member, a day after a ship burned and sank in Romania's zone; Turkey and Pakistan announced a "rapid deployment" of forces to Saudi Arabia under their Mecca defence pact. That lifts the military component by 2. At the same time yesterday's main open risk closed: Saudi Arabia's energy minister says the East-West pipeline is carrying 5.8 million barrels a day, so the AFP report of a halt did not hold. The formula gives 61.25: unchanged.

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 web monitors checked hourly. This is not continuous watching.

CP = 0.30×70 + 0.25×70 + 0.20×50 + 0.15×45 + 0.10×60 = 61.25 → 61. Band: 55.7 → 56 to 66.4 → 66.

What would lower the index (checklist): a US–Iran deal or a Yemen truce: no. Inventories stop falling and Hormuz reopens: partly (the bypass is restored, Hormuz is not, no stock data until the IEA report around 15 Oct). IMF WEO shows no contagion: pending. Taiz relieved: no. A date for trilateral Ukraine talks: no.

Signals

80 indicators collected on 6 Oct, 22:30 UTC; 2 anomalous.

• Bosporus transits (IMF PortWatch): 38.6 ships/day vs a baseline of 51 (×0.76), data to 4 Oct. The data end before the Romania and Bulgaria attacks, so the drop cannot be blamed on them; cause not established.
• News share tagged "arms deals" (GDELT): ×5.6 its baseline. Likely the Mecca pact and air-defence supply news; machine-tagged themes measure press attention, not procurement.
• Hormuz 2.7 ships/day (×0.9), Bab el-Mandeb ×1.14, Suez ×1.05: no anomaly.
• Satellite fire detections near Russian refineries: zero for 3 days, on the same night a geolocated fire burned at Volodarskaya. A method lesson: a FIRMS zero proves nothing about strikes (site list, clouds, data lag).
• Public anxiety readership (nuclear war, WWIII, shelters) at or below baseline.

None of these moves a score on its own.

1. Main finding

The day changed the shape of the risk, not its level. The energy node that looked most dangerous yesterday, the East-West pipeline that carries Saudi crude around Hormuz, is running near full load, and the market sees it (Argus, 6 Oct¹). The war, though, widened in geography and in the number of states: ships are being sunk in the economic zones of two NATO members, and Turkey and Pakistan have committed to a military presence in Saudi Arabia. Neither is a direct clash of major powers, but both shorten the path to one.

2. Significant new events

• Black Sea, Bulgaria's EEZ, 6 Oct ~03:00. Air and sea drones hit two merchant ships about 70 miles off Byala: the Togo-flagged Alfa Watan sank, its crew missing; the Palau-flagged Able (wheat) caught fire, 18 crew rescued, two badly hurt (AP, 6 Oct²; Reuters via Straits Times, 6 Oct³). Origin not officially established; a maritime security source told Reuters it was probably Russian; Zelensky blames Russia. Prime Minister Radev: the war "will continue to expand its geographical scope". NATO declined comment. On 5 Oct a Turkish grain ship burned and sank in Romania's EEZ after a drone strike, 2 dead (Sofia Globe, 5 Oct⁴).
• Mecca pact activated (5 Oct, Riyadh). Saudi Arabia, Turkey and Pakistan agreed "to move immediately to the practical implementation of the collective defence commitments" and ensure the "rapid deployment" of forces in the kingdom (Reuters via Khaleej Times, 6 Oct⁵; Middle East Eye, 5 Oct⁶). No numbers, roles or timetable; Turkey's parliament has not ratified the pact (Foreign Policy, 6 Oct⁷).
• Yemen. Government forces, with 100 coalition jets, claim Dhubab, Bab and Hadeid near Bab el-Mandeb (anonymous officials via AP, Euronews, 6 Oct⁸); the Houthis claim strikes on Riyadh airport and the Rabigh refinery; Saudi Arabia confirms attacks on Jizan and Najran airports, 3 injured.
• East-West pipeline. "As of this morning, we are back to 5.8mn b/d," Prince Abdulaziz bin Salman said; three of 11 pumping stations were damaged, the pipe itself was not (Argus, 6 Oct⁹). An interested source, but consistent with Reuters and Bloomberg sources on 5 Oct.
• Hormuz, 6 Oct. The Aframax On Peace was struck off Oman, 12 crew injured, 11 of them Indian (Seatrade, 6 Oct¹⁰). At least five ships attacked since 3 Oct. A continuing regime, not a new state.
• Russia–Ukraine. A large overnight drone raid on the Moscow region (Moscow's mayor claims 650 drones, a party's figure); the Volodarskaya pipeline station, the region's main fuel hub, caught fire, geolocated by Astra (United24, 6 Oct¹¹). Damage unknown. A tanker reportedly burned off Sochi (unconfirmed). Zelensky warned that Russia is preparing a massive strike (Kyiv Independent, 6 Oct¹²).
• Iran–US. Pezeshkian: talks "meaningless", "they have attacked us three times after talks" (Arab News/AFP, 5 Oct¹³). Qatar: talks and messages continue (Al Arabiya/AFP, 6 Oct¹⁴).

3. Links and hypotheses

• The Black Sea as a second "export war" at sea. Ukraine strikes Russian shadow-fleet tankers and fuel logistics; ships carrying Ukrainian grain burn in Romanian and Bulgarian waters. It mirrors Hormuz: each side hits the other's exports. Evidence for deliberate escalation (H2) if attribution to Russia is confirmed; for now it is Ukraine's claim and an anonymous source.
• The Mecca pact is a response to Houthi strikes, turning the Saudi–Houthi war into a coalition war. The causal chain is traceable in statements; it does not support a "common architecture" (H1). It looks reactive.
• Loss of control (H5): neither Bulgaria nor NATO names a culprit; Germany took almost a month to attribute the 4 Aug Leipzig drone (AP). Slow attribution is where incidents pile up without response.
• Markets (H6): the restored bypass pushed Brent under $100: prices follow physical flows, not attack counts.

4. Risk of a wider war

Higher, with no threshold crossed. New triggers: a crew killed in a NATO member's EEZ with confirmed Russian attribution; Turkish and Pakistani troops deployed where the Houthis strike, so losses would draw in a NATO member and a nuclear power; a massive Russian strike on Ukraine. Standing ones: US strikes on Iran after 3 Nov, attacks on the bypass routes. No direct clash of major powers.

5. Signs of de-escalation

• The East-West bypass runs at 5.8 mb/d, above its pre-attack rate.
• Brent below $100 (CFD quotes).
• Qatar confirms the US–Iran channel works; no US strikes on Iran since 1 Sep (AFP).

6. Corrections

• Yesterday the East-West halt was an open question (AFP vs Reuters/Bloomberg). The minister's figure resolves it as "flowing"; the AFP halt report was most likely wrong or described a short stop. My expectation of "partial disruption, not a full halt" held.
• The FIRMS zero for Russian refineries on the night of a geolocated depot fire is a limit of the method, not evidence of calm. No FIRMS-based inference for Russia without a second source from now on.

7. What to check next

• Black Sea: attribution, the Alfa Watan crew, any NATO Article 4 request, insurance rates (by 13 Oct).
• Mecca pact: size and roles of Turkish and Pakistani forces, Turkish ratification (by 20 Oct).
• Bosporus: does the traffic drop continue after 4 Oct (by 10 Oct)?
• Whether the warned massive Russian strike happens (by 9 Oct).
• Hormuz transits vs volumes; US–Iran; Ukraine's 51% refinery claim; China's fuel export curbs; Taiz.
