From liquidity spirals to network topologies: a bibliometric analysis of bank interconnectedness in polycrisis era

In the era of Polycrisis, where financial instability arises from interconnected pandemic, geopolitical, climate, cyber, and macro-financial shocks, the significance of bank interconnectedness has increased. This paper conducts a bibliometric and content analysis of 388 Scopus-indexed publications from 2013 to 2025, tracing the evolution of research on bank interconnectedness in these contexts. Beyond a basic bibliometric overview, it adopts a dynamic Polycrisis perspective, employing methods such as performance analysis, scientific mapping, keyword co-occurrence, theme development, burst detection, annual collaboration network metrics, and cluster-based content analysis. The results reveal a shift from a post-Global Financial Crisis focus on systemic risk, contagion, interbank markets, and financial regulation to a broader agenda including financial networks, network topology, bank supervision, resilience, and crisis response. The research is organized into six clusters: systemic risk and crisis contagion; liquidity spirals and regulations; banking stability and macroprudential policy; methodological innovation; network topology and shock resilience; and interbank market microstructure. Dynamic keyword analysis shows that financial networks, contagion, COVID-19, network topology, and fire sales increased in prominence during the Polycrisis period, while climate and cyber-risk channels remain less developed. This study redefines bank interconnectedness research as shifting from retrospective contagion analysis to predictive, adaptive, and policy-oriented network supervision.
