The clearing, settlement, and transaction systems that underpin daily economic activity.

View system →Long-term case studies in governance, resilience, and dependency.
Critical Dependencies studies a limited number of systems whose continued functioning is a precondition for modern economic and civic life.
These systems differ in ownership, governance, technology, and geography. Yet they often exhibit the same recurring patterns of concentration, redundancy, maintenance, complexity, governance, and institutional memory.
Each system is treated as a long-term case study rather than a collection of current events.
The objective is not to document everything that happens within a system.
The objective is to understand how the system evolves over time.
The publication currently focuses on nine critical systems. Each system will be studied through the lenses of governance, resilience, and dependency, and examined using the six foundational patterns that underpin the publication's methodology.
The generation, transmission, and distribution systems that provide continuous electrical power to modern societies.

View system →Every system study published by Critical Dependencies follows the same broad approach.
Each system is examined through:
and evaluated against the publication's six foundational patterns:
This creates a consistent basis for comparison across systems that may otherwise appear unrelated.
The systems included in this publication are not selected because they are currently in the news.
They are selected because they represent long-lived structures that societies depend upon every day.
Research will develop gradually over time.
The publication prioritizes depth, consistency, and historical perspective over volume.
Understanding critical systems requires patience.
We study systems, not actors.
