A multiplex network analysis of the Mexican banking system: link persistence, overlap and waiting times

Network centrality and funding rates in the e-MID interbank market

“…In the financial economic literature network analysis has mostly been applied to payment systems, interbank lending markets, and more recently extended to capture the mutual exposure of financial institutions to other asset classes, including derivatives contracts, in a multilayer networks framework (Bargigli et al (2015), Leon et al (2014), Molina-Borboa et al (2015), Aldasoro and Alves (2015), Poledna et al (2015)). …”

Multiplex Interbank Networks and Systemic Importance: An Application to European Data

“…For instance, how close the network resembles a coreperiphery structure depends on the asset class considered. Further related contributions are the papers by León et al (2014), Molina-Borboa et al (2015) and Montagna and Kok (2013 …”

“…Molina-Borboa et al (2015) find that important actors in the different layers differ 30 and take this as a significant reason to motivate the use of multiplex networks instead of just a single aggregated network. We argue on the basis of the results in this and previous sections that even in the case in which the importance of actors is strongly persistent across layers (as they show to be in the network of large European banks), there is still significant value in looking at all layers for which information is available (i.e.…”

Multiplex Networks of the Guarantee Market: Evidence from China

“…The study of financial multiplex networks has only appeared recently. Empirical analyses of the financial multiplex networks of Colombia, UK, Mexico, Italy, Europe, and USA are provided by León et al [28], Langfield et al [29], Molina-Borboa et al [30], Bargigli et al [31], Aldasoro and Alves [32], and Musmeci et al [33], respectively.…”

“…Langfield et al [29] construct the multiplex network of the UK interbank market and find that the network of interbank exposures exhibits a core-periphery structure and the funding network has less of a core-periphery structure. Molina-Borboa et al [30] analyze the persistence 2 Complexity and overlap of relationships between banks in a multiplex network of the Mexican banking system, where the multiplex network includes five layers, namely, collateralized loans between banks, new deposits and loans, securities, outstanding deposits, and loans and derivatives. Bargigli et al [31] analyze the Italian interbank multiplex network by transaction type and by maturity and find that layers have different topological properties and persistence over time.…”
