Mathematical model of econometric analysis and strategic financial management for designing bank

Forecasting bank interest rates is an urgent problem, which is of particular importance in the context of financial instability and economic sanctions, quarantine, epidemics, the banking sector of Russia has been exposed to during the post-COVID period. Fluctuation of market interest rates under the influence of various financial factors is one of the main characteristics of the modern market. To them the capture of inflationary expectations, government policy, supply and demand. Materials and methods. The research toolkit is based on the provisions of econometric research and strategic financial management with the subsequent use of computer software Statistica 6.0. One used materials from specialized periodicals, international and Russian scientific and practical conferences, materials published on the Internet. The purpose of developing a methodology for researching bank interest rates is to substantiate recommendations for building a management system for a model of bank interest rates, which combines the advantages of previous models and takes into account the qualitative properties and information content of the market. Results. One has developed a mathematical model for forecasting bank interest rates. Discussion. The study pays special attention to the behavior of the key rate as a factor influencing the state of the national economy. Conclusion. It is concluded that in modern conditions it is the forecasting of bank interest rates, which is built on the basis of methodological (mathematical) models of short-term risk-free interes t rates, that can be recommended for practical use.
