Centrality and Connectivity Metrics for Systemic Risk Assessment
Centrality metrics are pivotal in systemic risk assessment within financial network modeling techniques. They quantify the importance or influence of individual institutions based on their position in the network. Measures such as degree centrality, betweenness centrality, and eigenvector centrality help identify systemically significant entities.
Degree centrality assesses how many direct connections a node has, indicating its immediate reach within the network. Betweenness centrality measures the frequency with which a node acts as a bridge along shortest paths, revealing its potential to control information or liquidity flow. Eigenvector centrality considers not only direct connections but also the importance of connected nodes, capturing influence within highly interconnected systems.
Connectivity metrics complement centrality measures by evaluating the strength and density of linkages, offering insights into network robustness. High connectivity or clustering can facilitate contagion spread during crises, emphasizing each institution’s potential systemic impact. These metrics collectively aid in pinpointing vulnerabilities and monitoring systemic risk levels within evolving financial networks.
Matrix-Based Modeling Techniques in Financial Networks
