Abstract

The global financial system has undergone profound structural changes over recent decades, characterized by increasing integration across markets, institutions, and geographical boundaries. This integration has been driven by technological advancements, regulatory harmonization, and financial innovation, creating a complex web of interconnected relationships that transcend traditional economic boundaries. While financial integration theoretically promises enhanced efficiency and risk diversification, the 2008 global financial crisis and subsequent economic disruptions have revealed a more troubling reality: integrated markets may amplify rather than mitigate systemic risk during periods of economic stress. This research addresses the fundamental question of how financial market integration influences the propagation and amplification of systemic risk during economic downturns, challenging conventional wisdom that integration necessarily enhances financial stability. Traditional approaches to understanding systemic risk have largely relied on linear econometric models and correlation-based measures that fail to capture the emergent, non-linear dynamics characteristic of modern financial crises. These methods typically assume stable relationships between variables and overlook the critical role of network effects, feedback mechanisms, and threshold behaviors that can transform localized shocks into global contagion events. Our research addresses these limitations by developing a novel computational framework that integrates techniques from complex network theory, machine learning, and agent-based modeling to capture the multi-scale dynamics of financial integration and risk contagion. The central contribution of this work lies in identifying and characterizing what we term the 'integration-resilience paradox' – the phenomenon whereby increasing integration may reduce rather than enhance systemic resilience.
