情景与压力测试

A 压力测试 asks what happens to an organisation, system or plan under a severe but plausible event, before a real shock answers the question. Scenarios describe how such events might unfold; stress tests measure the effect on capital, capacity, services or people. This page sets out how scenarios are designed, how stress tests propagate shocks through dependencies, and how results serve the boards, ministries and supervisors that must act on them.

01登记

Scenario and stress testing on the record.

02问题

Scenario and stress testing: how the risk develops.

Challenging plans and assumptions. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

机制

Scenarios set the question

A scenario fixes the trigger, its severity, its timing and the conditions around it. Choosing only familiar or mild scenarios produces reassuring results that say little about real vulnerability.

机制

Shocks travel through the model

The stress spreads through dependencies represented in the test: suppliers, counterparties, infrastructure and staff. What the model leaves out cannot fail, so omissions bias results toward resilience.

机制

Responses change the outcome

Institutions react during a crisis by selling assets, cutting services or drawing on reserves, and those reactions affect others. Tests that hold behaviour fixed miss these second-round effects.

机制

Reverse tests find breaking points

Reverse stress testing starts from failure and asks which combinations of events would cause it. It reveals vulnerabilities that forward scenarios chosen in advance may never reach.

Stress tests that cross domains test the joins, not the parts.

Scenario work is designed for the 情景与压力测试系列, always labelled as scenario evidence. Financial supervisors use the NGFS scenarios for climate stress testing; national cross-sector tests need storylines built with each sector’s experts.

  • Storylines with the assumptions each sector’s experts checked.
  • Results of past stress tests a public body has published.

  • Reverse stress test protocols for public services and organisations
  • Exercise reports prepared for review by the institution tested
11核心问题

What scenario designers ask.

  • Is the scenario severe enough to be informative, yet plausible enough to be taken seriously?
  • Does it combine shocks that are likely to occur together, rather than treating them as independent?
  • Does it include the reactions of other actors, which can amplify or damp the shock?
  • What would the organisation actually do, and is that response realistic under stress?
12机制

Why scenarios reveal what forecasts miss.

Forecasts aim for the most likely outcome and tend to understate extremes. Plans built on them fail when the unusual happens. Scenarios deliberately explore the space of outcomes, including combinations that historical data has not yet shown. Reverse stress testing works backwards: it starts from failure and asks what would have to happen to cause it, which often exposes vulnerabilities that forward scenarios miss.

Stress tests reveal not only losses but behaviour: which decisions would be needed, who would make them, what information they would need and how long it would take. Many failures in real crises come from slow or unclear decisions rather than from the size of the initial shock.

13方法与局限

How scenarios and stress tests are built.

  1. 01

    Narrative scenarios

    Qualitative stories built by diverse groups around key uncertainties. Limits: can be shaped by group consensus and familiar fears.

  2. 02

    Quantified stress scenarios

    Consistent sets of shocks to model inputs, designed with scenario design and stress testing methods. Limits: model results depend on how the model represents behaviour under stress.

  3. 03

    Reverse stress tests

    Identify scenarios that would cause failure. Limits: many paths can lead to failure, and choosing which to study requires judgement.

  4. 04

    演练

    Tabletop and live exercises test decisions and coordination. Limits: participants know it is an exercise.

16问题

问题与解答。

What is a stress test?
An analysis of how an organisation or system would perform under a severe but plausible adverse scenario, used to find vulnerabilities and test buffers and plans.
What is reverse stress testing?
A test that starts from a defined failure, such as a service stopping or capital falling below a minimum, and works backward to identify the scenarios that would cause it.
Is a scenario a prediction?
No. A scenario is a plausible description of how events might unfold under stated assumptions, chosen to test a decision, and it carries no probability unless one is assigned.
Is a stress test a prediction?
No. It tests what would happen under a chosen scenario. The scenario is a tool for challenge, not a forecast.
How severe should a scenario be?
Severe enough to expose weaknesses, plausible enough that decision-makers act on the results. Reverse stress testing helps calibrate this.
Can the platform design a stress test for my organisation?
No. It publishes methods that organisations and authorities can apply themselves.
