Interconnectedness between stock and credit markets: The role of European G-SIBs in a multilayer perspective

Abstract

This paper investigates the interplay between two types of banking risk: market and credit. By verifying the volatility feedback loop hypothesis, we employ a multilayer information spillover network to explore information flow (risk spillover) between market and credit risks of European Global Systemically Important banks (G-SIBs). We analyse their role in transmitting market and credit risk, showing that capturing spillovers of both risks provides a more comprehensive perspective on financial risk contagion. Our findings have important implications for policymakers and risk managers, aiding in better risk assessment and timely crisis response, improving financial stability.
