The Economic Model of Banking Lending’s Impact on Long-Term Growth Rates: The Russian Economy as a Case Study

This study investigates the role of commercial bank lending in Russia’s economic growth, with a particular focus on the causal relationship between commercial credit expansion and macroeconomic performance. Employing econometric modeling and statistical analysis (Gretl), the research examines the dynamic interplay between banking sector credit volume and Russia’s GDP growth rate, utilizing key financial indicators: aggregate loan issuance to households and firms, real lending rates, GDP growth dynamics, and money supply (M2). Annual data from 2012 to 2019 were analyzed to assess the directional impact of bank credit on economic growth. Empirical results confirm a statistically significant positive relationship, demonstrating that private sector loan growth directly elevates real household income. Furthermore, the analysis reveals that banking credit exerts a disproportionately stronger effect on both GDP and monetary aggregates (M2) during fiscal consolidation phases—when government program funding contracts—compared to periods of unaccommodative monetary policy. These findings underscore the critical intermediation role of banks in growth stimulation, particularly in emerging markets undergoing structural fiscal transitions.
