Application of portfolio analysis in the typology of the state of development of the banking system

The article analyzes the banking system of the Russian Federation, which is a complex, multi-level, hierarchically structured system, in which various stable groups of banks are distinguished. The paper attempts to identify the category of banks based on the methods of portfolio analysis, but the results achieved require additional study, including: justification of the algorithm used, verification of the stability of the selected group of banks, as well as characteristics of its place and role in the banking system of the Russian Federation. Thus, the proposed tool for grouping commercial banks allows you to identify the most reliable of them and determine their financial stability. The results are interesting for the purposes of ranking banks by their investment attractiveness from the point of view of their reliability, as well as making management decisions on the formation of an optimal banking system.
