Impact chains

An impact chain states how a security development transmits into economic exposure or civilian impact, one step at a time, and grades how firmly each step is established. The grading is the point: a mechanism Vigil assesses as likely is shown differently from one that is documented, and a step can never be graded more firmly than the step it depends on.

Risk context, not investment advice. These records explain mechanisms and state how firmly each link is established. They contain no prices, tickers, named securities, forecasts or recommendations, and nothing here should be read as a view on any asset.

01

Economic exposure

3 chains

Energy import dependence → generation → industrial output

An advanced industrial economy with days of cover on the fuel it cannot store and no way to get more except by sea.

4 stepsConfidence: ModerateStatus as of 2026-06Reviewed 2026-07-26

Trigger. Near-total energy import dependence on an island with no pipeline or land connection, combined with a generation mix weighted toward a fuel that cannot be stored long

  1. Affected asset, route or regionConfirmed
  2. Operational disruptionConfirmed
  3. Exposed sector or commodityConfirmed
  4. Broader economic significanceUnconfirmed scenario

Exposure named: Electricity generation · LNG, coal and refined-product imports · Semiconductor fabrication continuity · Industrial output and manufacturing costs · Household and commercial supply

Semiconductor concentration → structural exposure → conditional propagation

4 stepsConfidence: ModerateStatus as of 2026-06Reviewed 2026-07-26

Trigger. The present concentration of advanced semiconductor manufacturing in a single geography, and the dependencies that concentration creates

Strait transit → freight and insurance → trade costs

What it costs when ships decide to go the other way round — and the four days in 2022 when they did.

4 stepsConfidence: ModerateStatus as of 2026-06Reviewed 2026-07-26

Trigger. Routine military activity conducted in waters carrying a substantial share of world commercial shipping, with periodic announced restrictions

Civilian impact

2 chains

Import dependence → household exposure → civil resilience

What twenty-three million people depend on arriving by sea, and what is actually known about the arrangements for when it does not.

4 stepsConfidence: ModerateStatus as of 2026-06Reviewed 2026-07-26

Trigger. A densely populated island importing almost all its energy and most of its food, with civil-defence structures designed around natural hazards

  1. Affected area or systemConfirmed
  2. Access or service disruptionConfirmed
  3. Civilian conditionConfirmed
  4. Broader humanitarian significanceUnconfirmed scenario

Exposure named: Electricity, water and sanitation continuity · Food availability and distribution · Health-service continuity · Communications and public information · Outlying-island community resilience

Undersea cable dependence → connectivity loss → civil services

An island connected to the world by a low double-digit number of cables, and what happened the last few times one broke.

4 stepsConfidence: ModerateStatus as of 2026-06Reviewed 2026-07-26

Trigger. Dependence for international connectivity on a small number of undersea cables in busy, shallow and contested water

  1. Affected area or systemConfirmed
  2. Access or service disruptionConfirmed
  3. Civilian conditionConfirmed
  4. Broader humanitarian significanceUnconfirmed scenario

Exposure named: International and inter-island communications · Digital payments and banking access · Emergency coordination and public information · Health and government service access · Outlying-island community connectivity
