Network science represents payment and market infrastructure as nodes and links: participants, سامانهها, settlement banks and providers. On this platform it maps dependencies, identifies critical nodes and simulates how a failure spreads.
Network science and contagion study how the structure of connections among entities shapes the spread of failures, information and disease. It provides tools to analyse interdependent infrastructure, supply chains and financial سامانهها. In financial stability, cyber and digital resilience and digital public infrastructure, network science identifies critical nodes and pathways through which shocks propagate across sectors. It informs targeted protection and diversification to limit cascades. The canonical description is on STEM Commons.
Interbank payment flows are analysed as networks to find participants whose delays would most affect others’ liquidity.
Dependencies of institutions on cloud, messaging and software providers are mapped to show concentration that individual views miss.
Common membership across CCPs is mapped to show how one member default could affect several clearing houses at once.
The screen a team would use to follow this method: its measures, states and decisions. Names are examples and values are illustrative.

No observed data enters this model: it runs on the teaching values set by the controls, to be replaced with a programme’s own evidence.

Models are checked by reproducing observed cascades and outbreaks. Robustness of results to missing or uncertain links is tested.
| بررسی | How it is done |
|---|---|
| Data coverage | The share of activity covered by the network data is stated |
| ثبات | Critical node rankings are checked across periods |
| Scenario realism | Simulated failures reflect plausible operational events |
Network data are often incomplete or confidential. Static network models may miss adaptive behaviour during cascades.
