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.

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 システム 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 STEM コモンズ.
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.

6 本の柱を通じて、Nexus Consortium が主導
Scenarios are reviewed for plausibility, internal consistency and severity relative to history. Exercise outcomes are compared with actual events when they occur.
| 確認 | 実施方法 |
|---|---|
| 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.
| シナリオ・ファミリー | 移行リスク | 物理的リスク | ストレステストが問うこと |
|---|---|---|---|
| 秩序ある | 早期の段階的な政策 | 低 | ポートフォリオは、着実な金利再設定を吸収できるか。 |
| 無秩序 | 遅く急激な政策 | 低から中 | 急な再評価と信用格付の移行で、何が破綻するか。 |
| ホットハウス・ワールド | 限定的な政策 | 高く、上昇中 | 物理的損失は、担保と保険のどこに集中するか。 |
