We study the network of Colombian sovereign securities settlements. With data from the settlement market infrastructure we study financial institutions’ transactions from three different trading and registering individual networks that we combine into a multi-layer network. Examining this...

An interacting network coupling financial institutions’ multiplex (i.e. multi-layer) and financial market infrastructures’ single-layer networks gives an accurate picture of a financial system’s true connective architecture. We examine and compare the main properties of Colombian multiplex...

Supervisory stress testing to date has focused on the resiliency of large banks to withstand the direct effects of a credit shock. Using data from Depository Trust & Clearing Corporation (DTCC), we apply the Federal Reserve's Comprehensive Capital Analysis and Review (CCAR) supervisory scenarios...

This paper builds a model of a regulation game, in which the active regulator moves first and designs the regulation requirement with the consideration of the network formed by banks and the associated systemic risk. Banks form the network strategically and diversify their portfolios within the...

This article explores the underlying structure of the intellectual research domains of the Italian community of banking and finance researchers. The goal of this study is to investigate research fronts and prominent topics and identify the links among these themes directly, based on the subject...

We propose a new methodology to assess intermediaries’ substitutability in financial networks featuring higher-order structures (credit intermediation chains). We represent the financial network as a hyperstructure and each credit intermediation chain as a hyperedge. This approach allows us to...

I study the systemic risks in financial networks under strategic attacks based on the framework of Elliott, Golub, and Jackson (2014). I obtain different results: Strategic attacks cause much larger cascades than random shocks do, and I identify the situations when financial networks are stable...

The composability and anonymity of participants in Decentralized Finance pose significant challenges in understanding their interactions and the buildup of risk within the network. We map the interconnections among decentralized finance protocols using transactions among contracts and addresses,...

We compare networks constructed using five commonly used methods and publicly available daily market data to networks based on reported exposures along several dimensions of the balance sheet, i.e., loans, bonds, equity. Our findings suggest that while the global network structure remains...

A model is developed where firms in a financial system have to settle their debts to each other by using a liquid asset. The question that is studied is how many firms must obtain how much of this asset from outside the financial system to make sure that all debts within the system are settled....
