Multiplex Financial Networks

 

Multiplex Financial Networks

 

These are multilayer networks but not Hierarchical (multi-scale) networks.  This is one of latest research area in financial networks. Several research papers published in 2015 and current year are using multiplex networks to analyze multiple credit relationships in Interbank market.

  • Short term debt chains
  • Overnight debt chains
  • Long Term Debt chains
  • Collateral chains

 

From The multiplex structure of interbank networks

 

Network analysis has contributed to characterize, understand and model complex systems of interconnected financial institutions and markets (Gai and Kapadia, 2010; Battiston et al., 2012). These tools are gaining popu- larity also among policymakers. Most contributions focus on the interbank market1, the plumbing of modern financial systems, especially in the Euro area. In the network perspective, the interbank market is commonly rep- resented as a standard directed and weighted graph. Each link represents a credit relation between two counterparties. Directionality identifies the borrower and the lender; the weight of the link represents the loan amount. In general, the interbank market is much richer and complex than a simple weighted graph. In this paper we explore the differences in credit relations due to maturity of the contract or the presence of collateral. Due to lack of data availability, existing empirical literature either (i) disregards the hetero- geneity of credit relations or (ii) focuses only on one type, implicitly assuming that the network of the selected type of credit relations is a good proxy for the networks of other types. In the latter case, the vast majority of contributions focus on the overnight unsecured market. These two approaches are parsimo- nious but may provide biased results if the underlying “representativeness” assumptions fail.

 

From  Interbank markets and multiplex networks: centrality measures and statistical null models

 

Interlinkages between any two financial institutions is more complex than the information that can be summarized in a single number (the weight of the link) and a direction, such as in a directed and weighted network. This is due to the fact that between two institutions there exists a multiplicity of linkages, each of them related to one class of claims/obligations. The interplay between different types of relation could be relevant for systemic risk analysis. In the network jargon, such a situation is best modeled with a multiplex network or simply multiplex. A multiplex is made up with several ”layers”, each of them composed by all relations of the same type and modeled with a simple (possibly weighted and directed) network. Since the nodes in each layer are the same, the multiplex can be visualized as a stack of networks or equivalently by a network where several different types of links can coexist between two nodes, each type corresponding to a layer.
