The article presents the results of a correlation and regression analysis of the spatial placement of banking divisions in Russia as a basis for the development of structural transformations corresponding to solving the problems of modernizing the country's economy and eliminating regional imbalances in socioeconomic development. Variants of a qualitative assessment of structural changes in the Russian banking system are proposed, taking into account Russian specifics and predictive studies. The authors' contribution is an introduction to the correlation-regression analysis of the territorial location of the banking structures of microfinance organizations to test the hypothesis of their mutual complementarity.
