Similarity and Clustering of Banks: Application to the Credit Exposures of the Czech Banking Sector
Brechler, Josef ; Hausenblas, Václav ; Komárková, Zlatuše ; Plašil, Miroslav
After the recent events in the global financial system there has been significant progress in the literature focusing on the sources of systemic importance of financial institutions. However, the concept of systemic importance is in practice often simplified to the problem of size and contagion due to interbank market interconnectedness. Against this backdrop, we explore additional features of systemic importance stemming from similarities between bank asset portfolios and investigate whether they can contribute to the build-up of systemic risks. We propose a set of descriptive methods to address this aspect empirically in the context of the Czech banking system. Our main findings suggest that the overall measure of the portfolio similarity of individual banks is relatively stable over time and is driven mainly by large and well-established banks. However, we identified several clusters of very similar banks whose market share is small individually but which could become systemically important when considered as a group. After taking into account the credit risk characteristics of portfolios we conclude that the importance of these clusters is even higher.

Míry podobnosti pro nominální data v hierarchickém shlukování
Šulc, Zdeněk ; Řezanková, Hana (advisor) ; Šimůnek, Milan (referee) ; Žambochová, Marta (referee)
This dissertation thesis deals with similarity measures for nominal data in hierarchical clustering, which can cope with variables with more than two categories, and which aspire to replace the simple matching approach standardly used in this area. These similarity measures take into account additional characteristics of a dataset, such as frequency distribution of categories or number of categories of a given variable. The thesis recognizes three main aims. The first one is an examination and clustering performance evaluation of selected similarity measures for nominal data in hierarchical clustering of objects and variables. To achieve this goal, four experiments dealing both with the object and variable clustering were performed. They examine the clustering quality of the examined similarity measures for nominal data in comparison with the commonly used similarity measures using a binary transformation, and moreover, with several alternative methods for nominal data clustering. The comparison and evaluation are performed on real and generated datasets. Outputs of these experiments lead to knowledge, which similarity measures can generally be used, which ones perform well in a particular situation, and which ones are not recommended to use for an object or variable clustering. The second aim is to propose a theory-based similarity measure, evaluate its properties, and compare it with the other examined similarity measures. Based on this aim, two novel similarity measures, Variable Entropy and Variable Mutability are proposed; especially, the former one performs very well in datasets with a lower number of variables. The third aim of this thesis is to provide a convenient software implementation based on the examined similarity measures for nominal data, which covers the whole clustering process from a computation of a proximity matrix to evaluation of resulting clusters. This goal was also achieved by creating the nomclust package for the software R, which covers this issue, and which is freely available.
