Chaos Pulse 64/100: weekly report, 10 October 2026

Chaos Pulse ends its first week at 64/100, up 3 from the initial 61. The Gulf bypass no longer offsets Hormuz, the Yemen war has reached Riyadh's airport terminals, Kyiv lost its metro and parts of its water supply. The week's main shift is political: the working US–Russia channel is opening a rift between Washington and Kyiv. A blind re-check of 6 October by an independent rater came out 5 points lower than my score.

CHAOS PULSE: 64/100 — severe crisis
Change: +1 since the previous report (9 Oct, 23:40 UTC); +3 over the week (initial reading on 5 Oct: 61).
Direction: worsening, slowly and without jumps. The main new shift of the week is not on a front line but inside alliances: Washington is pressing Kyiv, not Moscow.
Confidence: medium. Uncertainty band 58–69; widest components: economy (44–60) and restraint (55–66). A blind re-check of 6 Oct (below) put an independent score for the same events 5 points under mine; that is the honest noise threshold for now.
Why: (1) The US and Ukraine split in public. Axios and the FT reported on 10 Oct that envoys Witkoff and Kushner warned in Miami that intelligence sharing could stop if Ukraine kept striking Russian refineries; a US official denies any threat was made (Ukrainska Pravda/Axios, 10 Oct¹; Türkiye Today/FT, 10 Oct²). On 10 Oct Trump said "it's time for Ukraine to get a new President" (Meduza, 10 Oct³); the Miami talks ended a day early. (2) Riyadh's airport was attacked for the third time in a week: a missile hit the complex housing terminals 3 and 4, many were wounded, and operations were suspended (AP via US News, 10 Oct⁴; Asharq Al-Awsat, 10 Oct⁵). Trump said the US "may" join strikes on the Houthis (Firstpost, 10 Oct⁶). (3) Kyiv's metro stopped on all three lines and water supply was disrupted on 10 Oct (Kyiv Post, 10 Oct⁷). Index 63.75 → 64.

Scores are the author's judgement against fixed anchors (method v1, unchanged); facts carry sources. Checks: a daily report at 23:15 UTC (Mon–Sat), a weekly one on Sunday, plus hourly web monitors. This is not continuous watching. This is an analytical index, not a probability of war and not proof of any coordination.

Component (weight)	Score	Range	Change	Key reason
1. Military escalation (30%)	73	69–77	+1 (week +5)	New since 9 Oct: a missile hit the passenger terminal complex of the Saudi capital's airport and operations stopped (AP via Local10, 10 Oct⁸), the third attack on it in a week; Trump says the US "may" join strikes on the Houthis (no decision). The week's background: a coalition offensive in Yemen since 5 Oct backed by Saudi Arabia, Turkey and Pakistan, with Pakistani jets in the strikes (NYT, 7 Oct⁹); ships hit in Bulgarian and Romanian waters; an armed incident on Latvia's border; a series of strikes on Yandex data centres; heavy Russian strikes on Kyiv and Zaporizhzhia, at least 20 killed on 10 Oct (Euronews, 10 Oct¹⁰). Not 75: no direct clash between major powers, and the US pledge not to strike Iran before 3 Nov stands.
2. Energy and supplies (25%)	73	68–77	0 (week +3)	The 9 Oct state holds: Hormuz exports about 40% below pre-war and the Middle East about 10% below (Kpler via CNBC, 9 Oct¹¹); the Revolutionary Guard threatens ships "anywhere in the region" (Euronews, 9 Oct¹²). New on 10 Oct: a major fire at an oil terminal linked to the Novoshakhtinsk refinery (Kyiv Independent, 10 Oct¹³); Kyiv again without power and partly without water. Down: Russian diesel under OFAC General License 135; G7/IEA stock releases; US pressure could reduce strikes on refineries, though a senior Ukrainian official told the FT "we will burn refineries" (Firstpost/FT, 10 Oct¹⁴). Unchanged: the new strikes continue a campaign already counted.
3. Economy and finance (20%)	52	44–60	0 (week +2)	The US 10-year yield closed 9 Oct at 5.24% (Advisor Perspectives¹⁵), near its highest since the early 2000s; the dollar posted its longest weekly winning streak in a year and a half (Stocktwits, week to 9 Oct¹⁶); stocks steadied by Friday (Investopedia, 9 Oct¹⁷). Iran's rial hit a record low with inflation above 70% (Reuters via India Today, 4 Oct¹⁸). No banking or debt crisis. The blind re-check scored economy at 38: the main candidate for re-scoring after the IMF WEO.
4. Internal resilience (15%)	48	43–53	+1 (week +3)	New consequence: on 10 Oct all three Kyiv metro lines and electric surface transport stopped and municipal water supply was disrupted (Kyiv Post, 10 Oct¹⁹); DTEK said stabilisation schedules no longer apply (Al Arabiya/AFP, 10 Oct²⁰). This partly meets the threshold Kyiv's mayor named on 9 Oct (water damage), for hours rather than days. Saudi authorities warned that filming or sharing interceptions and impact sites exposes people to legal liability (AP, 10 Oct²¹). Yemen: the UN refugee agency counts 200,000 displaced (Al Jazeera, 7 Oct²²).
5. Restraint (10%; higher = weaker)	60	55–66	+2 (week 0)	Weaker: the US–Russia channel works, but it is cracking the US–Ukraine one: the reported intelligence warning (denied), Trump's call for a new Ukrainian president, Miami talks cut short, and Putin rejecting an end to the war in his call with Trump (Ukrainska Pravda, 10 Oct²³). Stronger: Putin relayed Iran's position on a peace deal to Trump (Kremlin via Asharq Al-Awsat, 10 Oct²⁴); the envoys plan a Moscow trip in late October (Axios via Meduza, 9 Oct²⁵). My −1 on 9 Oct for the diesel deal was premature; see "Revisions".

Chaos Pulse = 0.30×73 + 0.25×73 + 0.20×52 + 0.15×48 + 0.10×60 = 21.9 + 18.25 + 10.4 + 7.2 + 6.0 = 63.75 → 64.
Band: 0.30×69 + 0.25×68 + 0.20×44 + 0.15×43 + 0.10×55 = 58.45 → 58; 0.30×77 + 0.25×77 + 0.20×60 + 0.15×53 + 0.10×66 = 68.9 → 69.

What would bring the index down (checklist):

Military ↓ on a US–Iran deal or a Yemen truce: no. Iran is still reviewing the US response (Dawn, 9 Oct²⁶); the Yemen offensive and strikes on Riyadh continue.
Energy ↓ (to 65–68) if regional exports return to pre-war: no; next Kpler week on 14 Oct.
Economy ↓ if the IMF WEO shows no spillover: waiting (12–18 Oct).
Institutions ↓ if Taiz is relieved: partly. Government forces say they repelled a Houthi attack at the entrance to Taiz (Anadolu, 10 Oct²⁷), but the siege is not lifted; Kyiv is worse.
Restraint ↓ if a date is set for trilateral talks: no, the opposite: the Miami talks broke off early.

Signals

Collected 10 Oct, 22:30 UTC: 85 indicators, 4 anomalies.

GDELT news share tagged "states of emergency and curfews": ×5.9 against its baseline, the fourth day of growth (×2.1 → ×3.6 → ×5.35 → ×5.9); "power outages" ×4.9; "evacuations" ×2.6 (new). These match Kyiv and Riyadh. They measure press attention, not decisions.
Russian Wikipedia "Martial law" ×3.4 (data for 9 Oct): curiosity, not decisions; "Mobilisation" stays below baseline (×0.7).
Telegram: energy topics take 24% of posts in independent Russian media (norm 11%) and 12% in leak channels (norm 2%), driven by the diesel deal and refinery strikes.
Claimed strikes on Russian refineries: 6 sites in 7 days against a norm of 6.8, so the campaign runs at its usual pace, not a surge.
IMF PortWatch has not updated since 4 Oct (sixth day); Hormuz figures come from Kpler via press reports.

What signals do not prove: more coverage of emergencies is not an emergency declared; Telegram claims are leads, not facts.

1. Main finding of the week

The index rose from 61 to 64 not because of one shock but because several supports turned out weaker than I thought on 5 October. The Gulf bypass stopped offsetting Hormuz. The Yemen war became a war on the Saudi capital's airport. Strikes on energy reached Kyiv's metro and water, and civilian data centres in Russia. The most important change at the end of the week is political: the one working de-escalation channel, US–Russia, is being bought at the price of a US–Ukraine rift. This is bargaining, not a ceasefire: Ukraine is asked to stop alone while Russia keeps striking. The risk of a direct clash between major powers did not rise noticeably this week; the risk that the wars become longer and wider without any single centre did.

2. Chronology (4–10 Oct)

4 Oct: Iran's oil minister Paknejad resigns "for personal reasons"; NIOC chief Bovard acting (Al Arabiya/AFP, 4 Oct²⁸). Rial at a record low.
5 Oct: Yemen's government, backed by Saudi Arabia, Turkey and Pakistan, launches an offensive against the Houthis (CNBC, 4 Oct²⁹).
5–6 Oct: ships hit in Romanian and Bulgarian waters; on 6 Oct sea drones set the tanker Aframax Rio ablaze off Sochi, all 23 crew rescued; Greenpeace says the slick grew from 8 to 25 km² (Moscow Times, 9 Oct³⁰).
6 Oct: only 7 Hormuz transits, a two-month low (Kpler via Dawn).
7 Oct: mass strike on Ukraine; armed incident on the Latvia–Belarus border; Danish intelligence reports sabotage; bond sell-off and record diesel.
7–8 Oct: Houthi strikes on Saudi airports; three killed in Riyadh including a pilot (Reuters, 9 Oct).
8 Oct: tanker hit off Qatar; Omsk and Salavat refineries; first strike on a Yandex data centre; Trump pledges no strike on Iran before the 3 Nov elections.
9 Oct: Kpler shows the bypass no longer offsets Hormuz; IRGC threatens ships region-wide; second Yandex data centre; Ukhta refinery; Trump–Putin call, diesel deal and OFAC GL 135; Kyiv's mayor says the city is in survival mode.
10 Oct: Novoshakhtinsk terminal fire; Kyiv metro and water; at least 20 killed in south-eastern Ukraine; reported US intelligence warning (denied); Trump calls for a new Ukrainian president; missile hits Riyadh airport terminals, operations suspended; Trump says the US "may" join strikes on the Houthis.

3. Index over the week (real reports only)

Date (UTC)	Kind	Pulse	Mil.	Energy	Econ.	Inst.	Restr.
5 Oct 11:50	initial	61	68	70	50	45	60
5 Oct 23:30	daily	61	68	70	50	45	60
6 Oct 23:40	daily	61	70	70	50	45	60
7 Oct 23:40	daily	62	71	70	52	45	60
8 Oct 23:40	daily	62	71	71	52	45	59
9 Oct 23:40	daily	63	72	73	52	47	58
10 Oct 23:20	weekly	64	73	73	52	48	60

Week: +3, all inside the initial band (54–66). No single day moved 5 points or more. Military (+5) and energy (+3) drove the rise; restraint ended where it started.

Blind re-check (public commitment no. 3). An independent model (Claude Fable, a second AI model) scored 6 Oct without seeing my scores, using only my event log for that date and the brief's anchors: military 68, energy 64, economy 38, institutions 44, restraint 58, giving 56 (band 50–63) against my 61. Almost all of the 5-point gap is in economy (38 vs 50) and energy (64 vs 70). Caveat: the second rater saw only the event log, without background such as the bond market or stock draws, so this is spread between raters, not my own noise. Conclusion: changes below 5 points on my scale cannot be reliably told apart from the choice of rater, and the 61–64 level may run a few points high, mostly through economy. The method stays as it is, but economy will be re-checked against the IMF WEO; if it belongs near 40, that will be an explicit, explained recalculation.

4. Links between events and hypotheses

Established: Hormuz → bypass routes → strikes on the bypass → regional exports below pre-war. Houthis → coalition offensive → strikes on the Saudi capital. Ukrainian strikes on refineries → US diesel prices → Washington's pressure on Kyiv → the diesel deal with Moscow. The participants state this chain themselves: Trump on 10 Oct, "he goes and hits the diesel fuel. He better damn well stop."
H1, shared architecture: not supported. This week shows the opposite: actors are uncoordinated even inside alliances.
H2, deliberate escalation: stronger. Every side names an economic target openly: the IRGC targets firms "co-operating with the US", Kyiv targets Russia's revenue, Russia targets Kyiv's heating and power, the Houthis promise Saudi Arabia a long war (CNN, 8 Oct³¹).
H3, exploiting the crisis: plausible. US decisions are timed to the 3 Nov elections (the Iran pledge, diesel for prices); Saudi Arabia penalises filming interceptions. No evidence of intent to create the crisis.
H4, convergent interests: slightly stronger. Russia gains sanctions relief and diesel prices; bypass owners and US exporters gain from prices. Benefit is not proof of organisation.
H5, loss of control: stronger. Washington controls neither Kyiv, nor Riyadh, nor the Houthis; the IRGC widens its zone by its own logic.
H6, independent causes linked by markets: holds. Front-month Brent is near $104.7 (Convex, 10 Oct³²) while physical flows fall; physical Brent trades well above futures (see check c26 below).

5. Scenarios (no precise probabilities; registered forecasts cited where they exist)

A. Slow spiral (base case). Energy strikes continue on all three fronts, talks go on without results; Pulse 62–68.
B. Breakout. US strikes on the Houthis (new forecast #22), or IRGC strikes that halt the bypass terminals, or a Russia–NATO incident with casualties; Pulse 70+.
C. Partial freeze. A Russia–Ukraine energy truce (forecast #5, 4%) or a US–Iran framework before the elections; Pulse 55–60. Against: Putin rejected ending the war; Kyiv will not stop alone; Riyadh wants territory back before any Houthi truce.
D. A deal at Ukraine's expense. The US cuts intelligence (new forecast #23) and Kyiv halts refinery strikes (new forecast #24). Energy might ease while restraint and Ukraine's institutions worsen; the net effect is unclear. This branch became noticeably more real this week.

6. Risk of wider war

Up: the US openly considers joining the Yemen war; Pakistan and Turkey are already in the coalition; Syria is reported to be weighing support for Riyadh (Axios, 7 Oct). This is a path to more states involved, not to a clash between major powers.
Unchanged: Russia–NATO incidents in the Baltic and Black Sea; NATO's annual Steadfast Noon exercise from 13 Oct is scheduled, not a signal.
Triggers to watch: a mass-casualty Houthi strike in Riyadh; IRGC strikes on bypass terminals; deaths of a NATO-flag crew in the Black Sea; a halt of intelligence to Ukraine.

7. Signs of de-escalation

The Trump–Putin channel works, and Putin relays Iran's position: an indirect US–Iran channel.
The US pledge not to strike Iran before 3 Nov holds.
Russian diesel under GL 135 and G7 stock releases ease fuel shortages.

- Correction, 10 Oct (after publication): listing the diesel deal as a de-escalation sign was wrong. The immediate 300 kt is about 2.2 million barrels, roughly half a day of US distillate demand (about 4 million b/d, EIA); even the promised 1 Mt a month would be around 6% of US demand, and so far it rests only on Trump's word. Politically the deal does not lower tension: it shifts the blame for fuel prices onto Ukraine and splits the US–Ukraine channel (see the restraint row and "Revisions"). Only the G7/IEA stock release remains here.

Yemen's government reports advances near Bab el-Mandeb (The New Arab, 10 Oct³³); a party's claim, not yet verified.

8. Who gains, who pays

Gain: Russia (first sanctions easing, a US–Ukraine rift, high product prices); owners of bypass infrastructure and fuel exporters; defence industries; US politicians for whom pump prices before 3 Nov matter most.
Pay: Ukraine (grid, water, metro, and now its ally's trust); civilians in Saudi Arabia and Yemen; Iran's population (inflation above 70%, rationed petrol); importers in Asia and Europe; bondholders.
"Who benefits" does not show who organised anything: Russia's gain from the diesel deal follows from a US decision, not a Russian operation.

9. Emergency measures and powers

Saudi Arabia: legal liability for filming or sharing interceptions and impact sites (AP, 10 Oct). Watch whether it outlives the attacks.
US: the Defense Production Act for fuel is under discussion (Reuters, 9 Oct, three sources); OFAC GL 135 runs to 7 Apr 2027, a six-month "temporary" easing.
Iran: petrol quotas with a doubled price above quota since September (The National, 5 Oct³⁴).
Ukraine: emergency outages; stabilisation schedules suspended (DTEK, 10 Oct).

10. Revisions of earlier conclusions

"Bypass routes keep Gulf exports at pre-war levels" (5 Oct): wrong since 9 Oct (Kpler).
"East–West pipeline halted after Khurais" (AFP, 5 Oct): not confirmed (6 Oct).
On 9 Oct I cut restraint by 1 for the diesel deal and the call. That was premature: a day later the same deal turned into an intelligence warning and talks cut short. Lesson: sanctions relief for one side is not a sign that restraint works until the other side's reaction is visible.
The blind re-check of 6 Oct gave 56 against my 61: a possible upward bias, mostly in economy.
Checks that came due: c2 (Yemen counter-offensive) confirmed: offensive since 5 Oct, fighting at the entrance to Taiz on 10 Oct, attacks near Bab el-Mandeb continue. c11 (Iran oil minister) closed as unresolvable: "personal reasons", earlier requests refused (Bloomberg via Spokesman-Review, 5 Oct³⁵); pressure plausible, no sign of a purge. c21 (Bosporus traffic) no data: PortWatch frozen since 4 Oct; carried over. c26 (EIA Brent spot $125 vs futures near $100) confirmed: the EIA series is the Brent spot (FOB, physical cargoes), $125.44 on 6 Oct within a weekly range of $114–135 (EIA via CrudeOilNow³⁶); the physical premium is real and volatile.

11. What to check next

By 17 Oct: direct US strikes on the Houthis, yes or no.
By 19 Oct: economy against the anchors after the IMF WEO (12–18 Oct) and US CPI (14 Oct): 52 or nearer 40?
By 17 Oct: has intelligence sharing with Ukraine stopped, and have refinery strikes slowed (strike collector and news)?
By 14 Oct: Riyadh airport, length of the stoppage and airline cancellations (Air India suspended to 14–15 Oct, Firstpost, 10 Oct³⁷).
Kyiv water and transport (13 Oct); Fujairah (14 Oct); Russian diesel flows (16 Oct); next Kpler week (14 Oct).

Forecasts

24 open questions, 4 of them new; none resolved yet, so there is no track record until the first deadlines (Bank of Russia, 23 Oct). New questions (base rate → models → result; written before looking at any crowd price):

#21 Will Riyadh's airport be closed to commercial flights for 24+ consecutive hours by 31 Oct? Base 15%; signals ×2 (three strikes in a week, terminal hit) and ×0.8 (reopened within hours so far) → 22%.
#22 Will the US carry out acknowledged strikes on the Houthis by 30 Nov? Base 11% (two US campaigns in three years); signals ×3 (Trump's "may") and ×1.3 (support already flowing) → 30%; trend 25% → 27%.
#23 Will the US suspend intelligence sharing with Ukraine by 30 Nov? Base 10% (the March 2025 precedent); signals ×2.5 (reported warning) and ×1.2 (call for a new president), shaded down for the denial → 16%.
#24 Will there be a 14-day pause in Ukrainian strikes on Russian refineries between 11 Oct and 30 Nov? Base 15%; US pressure ×1.5, Kyiv's refusal ×0.6 → 13%.

Updated: #12 (Saudi–Houthi ceasefire by 31 Dec) 10% → 9% after the third strike on Riyadh's airport. All forecasts: pulse.errata.page/forecasts³⁸.
