Global Risks

Systemic & Cascading Risk

Systemic risk arises when failures spread through connected systems. A shock to infrastructure, finance, health or food supplies can trigger further disruptions across sectors and borders, making interdependence and resilience central to risk management.

Find your direction

Compare the choices that shape this path. There is no score or single right answer.

  1. What is your preferred unit of analysis?

    A network or model
    Develop quantitative and computational skills.
    An organisation or community
    Develop field research, planning and communication skills.

    Good risk work often needs both.

  2. Where do you want to intervene?

    Before a disruption
    Study prevention, design and investment decisions.
    During and after a disruption
    Study continuity, coordination and recovery.

    Preparedness connects these stages; they are not competing careers.

  3. How would you test your work?

    A simulation
    Make mechanisms explicit and vary assumptions.
    An exercise with users
    Observe whether responsibilities and alternatives work in practice.

    Model performance and practical usability are different forms of evidence.

Debates

  • Should essential services pay for spare capacity even when it is rarely used?Compare the case for: Alternatives can prevent one failure from interrupting a critical function. With the concern: Capacity has real costs and must be maintained.
  • Should infrastructure operators share dependency information?Compare the case for: Shared maps can reveal risks no operator sees alone. With the concern: Sensitive details need proportionate protection.
  • Is decentralisation always more resilient?Compare the case for: Distributed capacity may reduce dependence on a central component. With the concern: Many local units can still share a vulnerable supplier or technology.

Glossary

  • CascadeA sequence in which an initial disruption triggers further consequences through dependencies.
  • Systemic riskRisk to the functioning of a whole interconnected system, rather than only one component.
  • DependencyA requirement for another service, resource or process to function.
  • Common-cause failureSeveral components failing because they share the same underlying cause.
  • FeedbackA process in which an outcome changes the conditions that produce later outcomes.
  • ExposurePeople, assets or services located where hazards can affect them.
  • VulnerabilityConditions that make exposure more likely to result in harm.
  • RedundancyAdditional capacity or alternatives that can keep a function available if a component fails.
  • ResilienceThe ability to withstand disruption, adapt and restore essential functions.
  • Risk transferMoving risk between people, places or systems rather than necessarily reducing its total.
  • Early warningA linked capability for understanding risks, detecting hazards, communicating warnings and preparing action.
  • Stress testAn examination of performance under specified difficult conditions; its result depends on the scenarios tested.
