Interbank and counterparty contagion
Bilateral exposures are arranged as a network and default cascades are simulated to see how losses spread from an initial failure and which institutions amplify them.

Network science maps how banks are linked through interbank lending, derivatives, common asset holdings, payment flows and shared service providers. It shows where a single failure could cascade, which institutions are central to the system, and why contagion differs from the sum of individual bank risks.
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 Sistem. In financial stability, capital markets and investment and climate and hazards, 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.
Bilateral exposures are arranged as a network and default cascades are simulated to see how losses spread from an initial failure and which institutions amplify them.
Common holdings of securities and loans are mapped so that forced sales by one bank can be traced through price falls to losses at other holders.
Banks, payment systems, cloud and software providers are represented as a multilayer network to find concentration points whose failure would affect many institutions together.

Models are checked by reproducing observed cascades and outbreaks. Robustness of results to missing or uncertain links is tested.
| Pemeriksaan | Cara pelaksanaannya |
|---|---|
| Missing link sensitivity | Results are tested under alternative reconstructions of unobserved exposures, and the range is reported |
| Historical replay | Models are checked against known stress episodes and failures |
| Behavioural assumptions | Assumptions about liquidity hoarding, fire sales and recovery rates are stated and varied |
Network data are often incomplete or confidential. Static network models may miss adaptive behaviour during cascades.
Ekuitas yang hilang dari sistem setelah penularan antarbank, dibandingkan dengan pukulan awal, seiring berubahnya leverage, keterhubungan, dan tingkat pemulihan, yang merupakan inti dari Uji tekanan. Teaching model with stated illustrative values, not a prediction. The map on this page shows Western Europe; the model itself is not tied to a place.
