Chaos Pulse 64/100: daily report, 13 October 2026

Chaos Pulse holds at 64/100, but the risk has moved to sea. On land, Russia hit no Ukrainian energy targets for one night and Ukraine kept its refinery pause. Off Bulgaria a third merchant ship in nine days was sunk, with 11 sailors missing. In Hormuz six ships were hit in a single day, a wartime record. The IMF raised its global growth forecast.

CHAOS PULSE: 64/100 — severe crisis
Change: 0 since the previous report (12 Oct, 23:40 UTC); +3 over the week (6 Oct: 61).
Direction: no material change in the total, but the mix shifted: the sea got worse, land and the economy slightly better.
Confidence: medium. Uncertainty band 59–69; widest components: economy (43–59) and energy (69–78).
Why: on the night to 13 October Russia hit no Ukrainian energy targets for the first time since President Trump announced an "energy ceasefire", though it struck transport (Reuters, 13 Oct¹). Ukraine has not hit Russian refineries for two days, President Zelensky said (The Hindu, 13 Oct²). The sea got worse in two places. Off Bulgaria, a third merchant ship in nine days was sunk and 11 sailors are missing; Sofia summoned Russia's ambassador and asked NATO and the EU for help with surveillance (Stars and Stripes, 13 Oct³). In Hormuz, six ships were hit on 11 October, the most in a single day in this war (Al-Monitor, 13 Oct⁴), and a tanker and a container ship followed on 13 October. The IMF raised its global growth forecast to 3.1% and sees no sign of the crisis spreading to the world economy. The pluses and minuses cancel out: 64.25 → 64.

Scores are the author's judgement against fixed anchors (method v1, unchanged); facts carry sources below. Checks: a daily report at 23:15 UTC (Mon–Sat), a weekly one on Sunday (Bangkok time), 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%)	74	70–78	+1	Black Sea: overnight on 13 Oct drones hit the Chelsea 3 (Maltese flag, Ukrainian owner, crew rescued) and sank the HS Dignity about 17 nautical miles off Bulgaria; 11 of its 16 crew are missing (Reuters, 13 Oct⁵). It is the third sinking in the Romanian and Bulgarian economic zones in nine days. Prime Minister Radev: "We have no clear evidence to make accusations against either side, but logic suggests that the outcome benefits the Russian Federation"; Russia's ambassador was summoned and Bulgaria asked NATO and the EU for surveillance and help with the investigation (Stars and Stripes, 13 Oct⁶). The new consequence is a request to the alliance, not just a protest, so +1. Russia's defence ministry said it hit ships carrying military cargo to Mykolaiv and a rail depot in Kyiv (Reuters, 13 Oct⁷). The threshold for 76 (US strikes on the Houthis or Iran, a direct Russia–NATO clash) is not met.
2. Energy and supplies (25%)	74	69–78	+1	Up: six ships were hit on 11 Oct (two crude tankers, three product tankers, a cargo ship), a wartime record (Al-Monitor, 13 Oct⁸; The Telegraph, 13 Oct⁹); on 13 Oct UKMTO reported another tanker (UKMTO 171-26¹⁰) and a container ship struck. The Revolutionary Guard says ships with transponders off will be treated as hostile (IranWire, 13 Oct¹¹). Estimates of Gulf exports conflict: under half of pre-war levels (New York Post, 13 Oct¹²) against about 98% (Trading Economics); both are secondary. Down: one night without energy strikes on either side in the Russia–Ukraine war. The sea outweighs it: +1.
3. Economy and finance (20%)	51	43–59	−1	The IMF's World Economic Outlook (13 Oct) projects global growth of 3.1% in 2026 (revised up) and 3.4% in 2027, with inflation rising to 4.7% and risks tilted to the downside (IMF, 13 Oct¹³). No spillover into the world economy: that was my checklist condition for a cut. Brent holds near $106. An earlier blind re-check put this component at 38, so I cut one step, not a jump.
4. Internal resilience (15%)	49	44–54	0	Riyadh: the aviation authority extended the airport closure to 21:00 GMT on 17 Oct; it has been closed since 10 Oct (Reuters via Pajhwok, 13 Oct¹⁴); Air France-KLM suspended flights to the end of October and Delta postponed its new Riyadh route to March 2027. Yandex Cloud zones are still not restored (two open incidents on its status page). Ukraine: emergency power cuts after shelling in four regions (Ukrenergo, 13 Oct).
5. Restraint (10%; higher = weaker)	60	55–66	−1	Stronger: the first night without Russian strikes on Ukraine's energy (Reuters, 13 Oct); the Kremlin says contacts on the energy truce continue, with no progress yet (Xinhua, 13 Oct¹⁵); Iran says it is finalising its reply to the US, to be passed via mediators (IranWire, 13 Oct¹⁶). Weaker: asked about Russian strikes on six energy sites, President Trump said "Ukraine hit many sites the day before" and did not say Russia violated the truce (RBC-Ukraine, 13 Oct¹⁷); Russia has made no public commitment.

Chaos Pulse = 0.30×74 + 0.25×74 + 0.20×51 + 0.15×49 + 0.10×60 = 22.2 + 18.5 + 10.2 + 7.35 + 6.0 = 64.25 → 64.
Band: 0.30×70 + 0.25×69 + 0.20×43 + 0.15×44 + 0.10×55 = 58.95 → 59; 0.30×78 + 0.25×78 + 0.20×59 + 0.15×54 + 0.10×66 = 69.4 → 69.

What would bring the index down (checklist):

Military ↓ on a US–Iran deal or a Yemen truce: no. Iran is preparing a reply; Houthi drones and missiles toward Riyadh and Khamis Mushait were intercepted (Bloomberg, 13 Oct¹⁸).
Energy ↓ if both sides stop energy strikes and Hormuz reopens: one quiet night on land; Hormuz worse.
Economy ↓ if the IMF WEO shows no spillover: yes, −1.
Institutions ↓ if Riyadh airport reopens and Yandex's cloud recovers: no, the airport is closed to 17 Oct.
Restraint ↓ if Moscow confirms reciprocity: in deed for one night, not in words, −1.

Signals

Collected 13 Oct, 22:30 UTC: 85 indicators, 1 anomalous.

GDELT "evacuations": ×3.07 (2.24% of sampled news against 0.73%), the first fall after four days of growth (×2.58 → 3.21 → 3.57). Machine-tagged media attention, not events.
Russian Wikipedia "Martial law": ×1.79 (68 reads a day against 38; data for 12 Oct), down from ×2.32. Reads of Russian mobilisation articles are below normal.
Claimed strikes on Russian oil sites (Telegram): 1 site on 12 Oct against a norm of 1.5; on 13 Oct (partial day) only Ukrainian OSINT mentions, no official claim. Seven sites over seven days against a norm of 6.6: the pause shows only in the last two days.
Telegram topic shares: escalation is 12% of posts in independent Russian media (norm 5%) and 10% in Ukrainian media (norm 4%): the Black Sea, strikes on Kyiv, US pressure. Official Russian channels post about energy at 13% against 5%: the diesel deal and the truce.
UKMTO: warning number 171-26 on 13 Oct against 166-26 a day earlier, five in a day, the fastest pace so far (a counter of all UKMTO products, including the delayed reports about 11 Oct).
Satellite fire detections near refineries and terminals: below normal in all three regions (×0.61–0.63, data to 12 Oct): consistent with the pause, not proof of it.
IMF PortWatch is still stuck at 4 Oct.

What the signals do not prove: GDELT and Wikipedia measure attention; Telegram claims are not confirmed strikes; the UKMTO number is not a count of attacks; no satellite fire does not mean no strike.

1. Main finding

For one night the land energy war stopped on both sides for the first time in a month, but the crisis is moving to sea. Hormuz saw its worst day of attacks on shipping in this war. The Black Sea saw a third sinking in nine days off a NATO member's coast, with crews missing. In neither sea has the attacker been officially named. Both share a pattern: pressure on trade kept below the level that would oblige an alliance to respond. The IMF says the world economy is holding, so the total does not rise. The main risk has moved from energy prices to freedom of navigation.

2. Significant new events

Black Sea, night of 13 Oct. The Chelsea 3 was hit by three drones about 17–18 nautical miles off Byala; all 15 crew were taken off, five lightly injured. The HS Dignity, bound from Algeria for Brăila on the Romanian Danube, sank about 17 miles off Shabla; 11 of 16 crew are missing (Reuters, 13 Oct¹⁹; Al Jazeera, 13 Oct²⁰). Bulgaria's foreign minister asked NATO and the EU to help establish the origin of the drones and strengthen surveillance. Ukraine's foreign minister blamed Russia directly (RBC-Ukraine, 13 Oct²¹); that is one party's position, not an established fact. One Odesa broker estimates that about 90% of transit traffic now stays inside the 12-mile band to avoid war-risk premiums; both ships were outside it (Grosswald Signal, 13 Oct²², a single estimate).
Russia–Ukraine. Russia hit transport rather than energy overnight (Reuters, 13 Oct). The Kremlin spokesman said contacts on the energy truce continue without progress, that Russia seeks "lasting peace rather than a temporary truce", and that the diesel deal with Washington is not linked to Moscow's position on Ukraine (Xinhua, 13 Oct²³).
Hormuz. UKMTO's delayed reports show six vessels hit on 11 Oct, five in the strait and one near Oman's Sohar anchorage (The National, 13 Oct²⁴). Al-Monitor reports the spike came after a US jet disabled an Iran-linked tanker accused of running the US blockade. An adviser to the Revolutionary Guard commander said the strait "is closed" and that routes along Oman's coast would be closed too (Fars via The National). Attribution of individual strikes is not established.
Saudi Arabia. Riyadh's airport is closed until 17 Oct (Reuters via Pajhwok). Houthi missile strikes on the airport have killed 13 people and wounded more than 300 (LA Times, 13 Oct²⁵).
Iran–US. Iran's deputy foreign minister said Tehran is finalising its reply, but reopening Hormuz depends on the US honouring earlier commitments (IranWire, 13 Oct).
Economy. IMF WEO: 3.1% growth in 2026, inflation 4.7%. The Atlantic Council estimates the diesel deal would bring Russia about $4.7 billion of extra export income by year-end (Atlantic Council, 13 Oct²⁶).

3. Links between events and hypotheses

Pressure below the threshold at sea. In both seas merchant ships are attacked, no attacker is officially named, and the allied answer is surveillance and statements. Hypothesis (loss of control): +, since the series off NATO coasts grows faster than attribution. Hypothesis (deliberate escalation): + for Hormuz, where the Revolutionary Guard openly sets rules and penalties; for the Black Sea there is only Radev's "logic", no evidence. Hypothesis (a common architecture): not supported; two seas, different actors, a shared tactic only.
Competing blockades in Hormuz. Al-Monitor places the record day right after the US strike on a blockade runner. That is a sequence in time, not proven causation.
The land truce. One quiet night on both sides after two days of Ukraine's one-sided pause. Hypothesis (convergence of interests): unchanged. Russia gets diesel income and a pause without committing; the US president does not hold Russia responsible.
Markets: Brent holds near $106 despite record attacks and conflicting export estimates; the IMF sees resilience.

4. Risk of a wider war

Rising through the sea. In the Black Sea the attacks are on routes to the Danube ports of Romania and Moldova, off two NATO members; Bulgaria asks for surveillance, not Article 4 consultations. In Hormuz two blockades compete: the US one and Iran's claimed "control". No direct clash between major powers. The US is still only "considering" action against the Houthis.

5. Signs of de-escalation

The first night without Russian strikes on Ukraine's energy; two days without Ukrainian refinery strikes.
The Kremlin says truce contacts continue.
Iran is finalising its reply to the US; the mediated channel is open.
The EU opened two more accession clusters with Ukraine (13 Oct): a political signal, not a military one.

6. Corrections

On 12 Oct I reported a tanker and a container ship hit in Hormuz (UKMTO 166-26). UKMTO's delayed reports show six ships were hit on 11 Oct. Same event, larger scale. I did not move the energy score for it on 12 Oct and count the difference once, today.

7. What to check next

Black Sea: the 11 missing crew; NATO's response (surveillance, ships, aircraft); any official attribution (by 20 Oct).
Gulf exports: under half of pre-war or about 98%? Ship-tracking data (by 16 Oct).
Does Russia's pause on energy strikes hold (by 25 Oct, checked daily).
Riyadh airport: does it reopen on 17 Oct.

Checks resolved today: Black Sea attribution and Article 4 (expected "no official attribution to Russia, no Article 4 request by 13 Oct"): correct. Omsk refinery output (expected "partial cut, no full stop"): not verified; I found no open data, so I close it as moot, not as correct. Kyiv water and power (expected "emergency cuts continue, no mass water failure"): mostly correct. Riyadh airport closed for a clean 24 hours: correct; forecast #21 resolved yes.

8. Sources and data limits

Primary and official: UKMTO 171-26 (13 Oct); Saudi aviation authority (via SPA, 12 Oct; via Reuters, 13 Oct); Bulgarian government (via Reuters, AP, Stars and Stripes, 13 Oct); Ukraine's foreign ministry (13 Oct); Russia's defence ministry and the Kremlin (via Reuters, Xinhua, 13 Oct); IMF WEO (13 Oct); Ukrenergo (13 Oct); Iran's deputy foreign minister (via IranWire, Mehr, 12–13 Oct).

Limits: attribution of the attacks in both seas is not established; Gulf export estimates conflict; Russia has not confirmed the truce in words and one night is not a trend; IMF PortWatch data end on 4 Oct.

Forecasts

Resolved #21 (Riyadh airport closed to all commercial flights for ≥24 consecutive hours starting 11–31 Oct): yes. My last probability was 85%, my first 22%. The aviation authority extended the suspension on 12 Oct, and per Reuters the airport stays closed until 17 Oct. Updated: #7 (a NATO member requests Article 4 consultations by 31 Dec) 18% → 20%: a third sinking and Bulgaria's request for help, but Sofia declines to accuse anyone; #24 (14 days without a Ukrainian refinery strike by 30 Nov) 30% → 33%: the pause holds for a second day and Russia hit no energy for one night; #5 (Russia publicly commits to a reciprocal halt of energy strikes by 20 Nov) 5% → 6%: contacts continue, no commitment.
