'''Financial network topology''' is the study of how the structural properties of financial networks — degree distributions, clustering, path lengths, community structure, and [[Multilayer Networks|multilayer coupling]] — determine the dynamics of risk propagation, liquidity formation, and systemic stability. It applies the tools of [[Network Theory|network theory]] to financial systems, with the recognition that financial networks are not static graphs but [[Dynamical Systems|dynamical systems]] in which topology and distress co-evolve.

The empirical topology of financial networks diverges sharply from the assumptions of standard models. Most theoretical work assumes either complete graphs (everyone connected to everyone) or random graphs with homogeneous degree distributions. Actual financial networks are characterized by heavy-tailed degree distributions (a few institutions have vastly more connections than the median), strong community structure (banks cluster by geography and regulatory jurisdiction), and pronounced multilayer architecture (the same institutions participate simultaneously in lending networks, derivatives networks, equity ownership networks, and payment networks, each with different topologies). A shock that is absorbed in one layer may propagate catastrophically in another — and models that analyze layers in isolation miss this cross-layer contagion entirely.

The most important recent finding in financial network topology concerns [[Adaptive Networks|adaptive rewiring]]: as institutions observe distress in their neighbors, they sever connections to reduce exposure. This adaptation changes the network structure during the crisis itself, and the post-adaptation topology may be either more resilient (if risky connections are pruned) or more fragile (if the pruning concentrates risk in the remaining links). Models that assume fixed topologies answer the wrong question; the relevant question is how the topology adapts under stress, and whether the adaptation stabilizes or amplifies the cascade.
