Models for Ensuring the Stability and Development of the Russian Banking System under Conditions of Global Financial Blockade

Abstract

Under unprecedented sanctions restrictions, the Russian banking system faced the necessity of radical transformation of its operational model. This study presents a comprehensive analysis of adaptation and development mechanisms of the banking sector under financial isolation. The methodological framework consists of structural-functional analysis, comparative methods, and econometric modeling. Key systemic risks were identified: disruption of correspondent relationships, limited access to international payment systems, foreign currency deficit, sanctioning pressure on counterparties. A multi-level sustainability model has been developed, including: institutional level (creation of alternative SPFS infrastructure, MIR national payment system), operational level (reorientation towards Eastern markets, development of settlements in national currencies), technological level (digitalization of banking processes, implementation of blockchain solutions), regulatory level (macroprudential regulation, stress testing). A development strategy is proposed through the formation of regional financial alliances with BRICS, SCO, EAEU, creation of parallel payment corridors, development of the digital ruble. Practical significance lies in developing a roadmap for banking system transformation, ensuring not only survival under sanctions, but also creating competitive advantages through technological sovereignty.
