Economic analysis in the context of controlling the diversification of bank resource sources

Subject. This article analyzes the diversification of funding sources for bank resources, which can be viewed as a procedure for internal control of the bank's resilience to external risks. Objectives. The article aims to develop an analytical methodology for assessing the structure, stability, and qualitative characteristics of financial sources of bank resources. Methods. For the study, I used systems and comprehensive approaches, methods of economic analysis, and statistical methods. Results. Based on the assessment of the diversification of funding sources for financial institutions, the article proposes a funding diversification index that helps not only quantitatively assess the structure of banks' resource base but also qualitatively interpret its stability. Conclusions and Relevance. The proposed funding diversification index is an effective tool for the comprehensive assessment of a bank's resource base during internal control of the diversification of funding sources. The method helps take into account both quantitative and qualitative characteristics of funding sources and identify potential risks of resource provision. The developed methodology can be used to assess the diversification of funding sources as part of the analytical procedures for the internal control of the bank's resource support. The scope of application of the research results includes financial and credit organizations, internal bank control services, risk management departments, and regulatory financial authorities.
