Financial Networks
Abstract
Financial systems are complex adaptive structures in which institutions, instruments, and markets are interconnected through intricate webs of dependencies. Viewing finance through the lens of network science provides a quantitative framework to analyse systemic risk, contagion dynamics, market stability, and structural fragility. In this talk, we explore how network theory enables the reconstruction and characterisation of financial architectures—from interbank lending networks to ownership structures. Particular attention is devoted to the role of topology in amplifying or mitigating shocks, the emergence of “central” nodes and Debtrank analysis, as well as distress propagation mechanisms underlying systemic crises.

Short Bio
Guido Caldarelli is a theoretical physicist and complexity scientist whose work focuses on network theory and its applications to economic, financial, and social systems. He is Professor of Theoretical Physics at Ca’ Foscari University of Venice and Director of the Institute of Complex Systems at the Italian National Research Council (CNR-ISC). His research explores the structure and dynamics of complex networks, systemic risk in financial systems, and the quantitative modelling of socio-economic phenomena using tools from statistical physics and data science. He has contributed extensively to the development of network-based approaches to understanding interconnected systems and is author of numerous scientific publications and books on complex networks and systemic risk. APS Fellow and NETSCI Society founder, he is member of European Academy of Science and served as President of the Complex Systems Society.
