Systemic risk propagation in the Eurozone: A multilayer network approach

n this paper, we study systemic risk propagation by exploring the dynamic mechanism of financial contagion among Eurozone countries. Using a multilayer information spillover network framework, we can consider the sovereign, banking and equity sectors’ risk spillover between countries simultaneously. This specification helps us to better identify the systemically important countries, i.e., the Eurozone financial stability. The findings emphasize the prominence of considering systemic risk propagation in a multilayer network structure. In fact, our empirical analysis suggests that considering intra-layer and inter-layer propagation is essential to gain a deeper insight into Eurozone systemic risk mechanisms.
