Abstract: An interdependent network coupling financial institutions’ multiplex (i.e. multi-layer) and financial market infrastructures’ single-layer networks gives a more accurate picture of a financial system's true connective architecture. We examine and compare the main properties of Colombian multiplex and interdependent financial networks. Coupling financial institutions’ multiplex networks with financial market infrastructures’ networks removes modularity, which augments financial instability because the network then fails to isolate feedbacks and limit cascades while it retains its robust-yet-fragile features. Moreover, our analysis highlights the relevance of infrastructure-related systemic risk, corresponding to the effects caused by the improper functioning of financial market infrastructures or by financial market infrastructures acting as conduits for contagion.
