Chaos Pulse 66/100: daily report, 18 October 2026

Chaos Pulse holds at 66/100. Ukraine flew one of the largest drone raids of the war and set an oil export terminal in St Petersburg on fire; Russia kept hitting Ukraine's grid. But the US resumed missile-warning intelligence for Kyiv, Riyadh's airport reopened and Egypt's parliament postponed its vote on defending Saudi Arabia.

CHAOS PULSE: 66/100 — severe crisis
Change: 0 since the previous report (17 Oct, 23:40 UTC: 66; more precisely 66.15 → 66.45); +2 over the week (11 Oct: 64).
Direction: plateau. Both sides of the war in Europe hit each other's rear harder, but two channels I had counted as fraying worked again, and Egypt paused.
Confidence: medium. Uncertainty band 61–71; widest components: economy (42–57) and energy (72–81).
Why: overnight on 18 October Ukraine launched one of the largest drone attacks of the war; Russia's defence ministry said it downed 1,015 drones over Moscow and western regions (ABC News, 18 Oct¹). In St Petersburg the oil terminal, the Ruchyi oil depot and warehouses in Kolpino burned and one person was killed, according to Governor Alexander Beglov (Politico Europe, 18 Oct²). The Kremlin said the attacks "cannot change the course of events" (AFP via The Straits Times, 18 Oct³). Lithuania sent residents of its centre and north to shelters for about an hour over an unidentified flying object that probably entered from Poland (Reuters via Internazionale, 18 Oct⁴). On the other side of the ledger, President Zelensky said the US had resumed sharing data on Russian ballistic missile launches after a three-day pause (Kyiv Independent, 18 Oct⁵). Military +1; energy 0 (St Petersburg offset by incidents of 11 October dropping out under the 7-day rule); institutions 0 (France +1, Riyadh airport reopening −1); restraint 0 (intelligence −1; Netanyahu's doctrine and Moscow's unchanged aims +1).

How it is computed: scores are my own judgement against the anchors of the method (v1 plus, since 17 Oct, a 7-day rule for incidents); facts carry sources. Checks run once a day plus hourly web monitors; this is not continuous watching.

Component (weight)	Score	Range	Change	Key reason
Military escalation (30%)	79	75–83	+1	Record raid by Russia's own count and the biggest attack on St Petersburg since 2022; Lithuania's "red" air alert with shelters, NATO jets scrambled, object likely from Poland (Reuters, 18 Oct⁶). Netanyahu presented a doctrine of pre-emptive action against Iran "not dependent on American approval" (Israel Hayom, 18 Oct⁷): rhetoric, but from the head of government nine days before an election. Egypt postponed its vote (Middle East Eye citing Reuters, 18 Oct⁸).
Energy and critical supplies (25%)	77	72–81	0	New: fire at the St Petersburg oil terminal (an export hub of about 12.5 Mt a year, per RBC-Ukraine, 18 Oct⁹) and the Ruchyi depot; 20,000 without power in Yanino (ABC News, 18 Oct¹⁰). Zelensky counts 76 Russian attacks on Ukraine's energy sector in the week since the "energy ceasefire" (Ukrainian figure). Dropped out after 7 days: the 11 October strikes on Kharkiv CHP-5 and Kyiv's grid and the record six ships hit in Hormuz that day. Hormuz unchanged: Iran's seven-day reopening offer is "still on the table", unaccepted (Reuters via Straits Times, 18 Oct¹¹).
Economic and financial resilience (20%)	49	42–57	0	Brent futures closed at $109.69 on 16 Oct vs $105.64 on 15 Oct (World Oil Monitor, aggregator¹²); no new financial stress found.
Domestic and institutional resilience (15%)	50	45–55	0	France: over half a million marched on 17 Oct, nearly 2,400 arrests, almost 1,000 police injured, Limoges city hall burned; Macron allowed local protest bans but no state of emergency (France 24, 18 Oct¹³) (+1). Riyadh airport reopened, though several airlines extended cancellations (The National, 18 Oct¹⁴) (−1).
Restraint mechanisms (10%; higher = weaker)	62	57–67	0	For: US missile-warning intelligence to Ukraine restored (−1); Zelensky expects a new meeting with Trump's team this week. Against: Netanyahu's "no US approval needed"; the Kremlin's unchanged aims; US Treasury Secretary Bessent would not call Ukraine an ally (Reuters via KSL, 18 Oct¹⁵) (+1).

CP = 0.30×79 + 0.25×77 + 0.20×49 + 0.15×50 + 0.10×62 = 66.45 → 66. Band 61.4–71.5 → 61–71.

Signals

86 indicators collected on 18 Oct, 22:30 UTC; 1 anomalous against its own history. GDELT share of news tagged "evacuations" ×2.35 and "power outages" ×2.41: attention, not counts of people. Telegram: escalation topics in independent Russian media 17% of posts vs a 7% norm; Ukrainian OSINT channel volume nearly double its norm after the raid. Satellite fire detections near Persian Gulf refineries ×1.36 (flares and fires look alike). Claimed strikes on Russian oil sites over 7 days: 5 vs a norm of 6.1, so Ukraine is not striking more often since the pause ended, but bigger targets. None of this proves a new phase.

Main finding

A day of symmetric escalation in the rear, with channels still working. Ukraine answered the Russian General Staff's openly announced campaign against its energy system (16 Oct) with a record raid and a hit on the export terminal of Russia's second city. Yet Washington, which was pressing Kyiv on 16 October, restored its missile warnings, and Egypt did not vote for a military mandate the same day. The index holds because rising intensity is balanced by channels that did not snap.

Hypotheses (labelled as such)

Russia keeps its energy campaign at full pace (my H2): supported by Kyiv's count of 76 attacks; no independent tally yet.
Declared ceasefires without verification erode trust (H5): both sides hit energy harder in the week after the "energy ceasefire" than before it.
A US–Russia bargain at Ukraine's expense (H4): slightly weaker. Restored intelligence is the first US step toward Kyiv in two weeks; Bessent's refusal to say "ally" cuts the other way. The sequence (strikes resumed 15 Oct, intelligence back 18 Oct) is an observation, not proof of cause.

Risk of widening

The short chain is moving north: a third day of stray drones over Lithuania and Poland, and for the first time residents of a NATO country were told to take shelter. Nobody has invoked Article 4. In the south, if Egypt's parliament votes on 19 October and Saudi Arabia asks, a third state enters the Yemen war.

Signs of de-escalation

US intelligence for Ukraine restored; Riyadh airport open; Egypt slowing down and stressing "defence only"; Iran's offer on Hormuz still on the table.

Corrections

My check that Egypt's parliament would grant the mandate on 18 October (p 0.86) was wrong for that day: the vote was postponed to 19 October. Forecast #26 (deadline 25 Oct) moves from 86% to 75%.
Lithuania: no contradiction found. Ukraine's foreign ministry said the drone was Ukrainian and diverted by Russian jamming, and Lithuania's army says it probably entered via Poland (Reuters); Politico still calls its origin unclear. Attribution rests on Kyiv's own statement.

What to check next

Egypt's vote (19 Oct); Russia's response to the St Petersburg raid and whether loadings at the terminal stopped; the North Atlantic Council on the Black Sea (20 Oct); an independent count of strikes on Ukraine's grid; Israel before the 27 October election; France's next protest day.

Limits: "1,015 downed" is Russia's figure and "76 attacks" is Ukraine's; damage to the terminal and any halt to loadings are unconfirmed; the Brent close is from a single aggregator.
