From Russia with love: The resilience of monetary policy transmission channels during Western sanctions and the monetary regime shift

This paper applies a macroeconometric approach to analyze structural shocks and their impact on the key transmission channels of monetary policy in Russia, focusing on the period since the imposition of sanctions and the monetary regime shift beginning in 2014. The approach combines the Lee–Strazicich LM test, used to identify structural breaks, with a Bayesian VAR model that estimates the posterior distribution of shock effects and responses. The model is further extended by dummy variables indicating the periods of imposed sanctions in 2014, the change in the Bank of Russia's monetary policy in 2015, and the Russia–Ukraine conflict in 2022. The findings indicate that the interest rate transmission channel operates in a fully asymmetric manner: the short run is characterized by the monetary policy shift, and the long run — by the conflict in Ukraine, suggesting the implementation of an expansionary and later highly restrictive policy with a temporary dual approach. The credit and exchange rate transmission channels are identified as the two most important stabilization mechanisms for macroeconomic shocks, with the 2015 regime change significantly enhancing the absorption of exogenous shocks. In contrast, the extended price transmission channel exhibits a more moderate capacity for shock absorption, underscoring the Bank of Russia's success in anchoring inflation expectations. Overall, the findings confirm that proactive monetary policy shapes inflation expectations effectively by employing two main tools: managing the key interest rate to control inflationary pressures and managing the ruble exchange rate to stabilize the economy.
