5.1Assumptions

Scenario SCN-SGP-ENE-01: what is assumed, and what is held constant.

Baseline
the 2026 reference state in this edition
Drivers
an interruption to oil and gas flows through the Strait of Hormuz that tightens imported fuel for power and industry, during a period of high heat stress
Analogues
the 2026 energy price shock described in the IMF record1920; 29 days of high heat stress in 202523
Interventions
none modelled; the specification describes the unmitigated case
Run state
narrative specification; quantified Foundry run scheduled for Q1 2027

5.2The cascade, step by step

  1. 1

    TRD → ENE

    imported gas and fuel supply tightens

    IMF exposure data20

  2. 2

    ENE → WAT

    power constraints reach desalination, NEWater and pumping

    expert input

  3. 3

    ENE → FOO

    cold chains and logistics lose power margin

    expert input

  4. 4

    CLI → HLT

    heat stress raises cooling demand and demand for care

    heat days23

  5. 5

    ENE → DAT

    data services and their cooling compete for power

    expert input

  6. 6

    ENE → FIN

    the energy price shock reaches inflation and fiscal support

    IMF19

5.3The scenario as a table of steps

How the shock in scenario SCN-SGP-ENE-01 would travel through Singapore’s coupled systems, step by step, under the assumptions the edition states.
