Climate scenario analysis of portfolios
NGFS pathways are translated into sector and company shocks to earnings, asset values and credit spreads, then applied to holdings, with each translation step and its assumptions recorded.

Spatial financeDonde el capital se encuentra con la amenaza, la exposición y la transición
Scenario design and stress testing explore how portfolios and funds would fare under severe but plausible conditions: disorderly transitions, physical climate shocks, market-wide redemptions or sudden rate rises. They complement statistical risk measures where history offers little guide, and their value lies in transparent assumptions rather than in any single result.
Scenario design and stress testing construct plausible, severe future conditions to examine how sistemas and institutions would perform. They complement probabilistic analysis where data are scarce or futures are deeply uncertain. In capital markets and investment, climate and hazards and biodiversity and nature, stress tests reveal vulnerabilities that arise when several risks materialise together. They inform capital, contingency and coordination plans across sectors. The canonical description is on el bien común CTIM.
NGFS pathways are translated into sector and company shocks to earnings, asset values and credit spreads, then applied to holdings, with each translation step and its assumptions recorded.
Fund outflows, collateral calls and dealer capacity are combined in one scenario so that second-round sales across funds with common holdings can be traced.
The analysis starts from an outcome a board cannot accept, such as suspended dealing or a funding shortfall, and works back to the combinations of conditions that would cause it.

Tres familias de escenarios según el marco de la NGFS llevan una cartera sectorial a través de los costos del carbono y los daños del calentamiento; la vista de transmisión sigue las pérdidas hasta prestamistas, inversionistas, finanzas públicas y hogares. Escenario: supuestos explícitos sobre el futuro, no un pronóstico.

En los seis pilares, bajo la dirección de Nexus Consortium
Scenarios are reviewed for plausibility, internal consistency and severity relative to history. Exercise outcomes are compared with actual events when they occur.
| Verificación | Cómo se hace |
|---|---|
| Plausibility and severity review | Scenarios are compared with historical episodes and with supervisory severity levels |
| Internal consistency | Shocked variables are checked against each other so no scenario combines incompatible paths |
| Assumption register | Every behavioural and pricing assumption is listed with its source and the sensitivity of the result to it |
Scenario choice can reflect prevailing assumptions and miss novel combinations. Results depend on how participants and models represent responses.

How scenario analysis for portfolios could be stressed under the scenario families central banks and supervisors use.
| Familia de escenarios | riesgo de transición | Riesgo físico | Qué plantea una prueba de estrés |
|---|---|---|---|
| Ordenada | Política temprana y gradual | Más bajo | ¿Puede la cartera absorber un reprecio sostenido? |
| Desordenada | Política tardía y abrupta | De bajo a medio | ¿Qué se rompe ante un reprecio repentino y una migración crediticia? |
| Mundo invernadero | Política limitada | Alto y en aumento | ¿Dónde se concentran las pérdidas físicas en las garantías y los seguros? |
