Assessing the effectiveness of the inflation targeting framework via the interest rate channel remains crucial in the current monetary policy debate. For Ukraine, the relevance of this discussion is enhanced by the adoption by the National Bank of a rigid inflation targeting policy since 2016, as well as by the challenges of price stability during war. The aim of the study is to identify how the discount rate affects the money market rates and how this affects inflation in Ukraine. Employing a VAR model on monthly data spanning 2016 – Q1 2022, the analysis demonstrates weak empirical evidence for the interest rate channel effectiveness. The impulse response indicates that the discount rate’s initial effect does not provide long-term inflation dynamics control. Variance decomposition analysis highlights the minimal influence of the NBU’s discount rate, primarily evident in the refinancing rate, followed by its impact on the rate of term deposits made by individuals, followed by the inflation, followed by the rate of new loans granted to residents, and finally the rate of government bond yields. Addressing the limitations of a rigid inflation targeting approach, the study recommends adopting a balanced approach, considering both price stability supported by exchange rate control measures and fostering economic growth. Additionally, a viable strategy for deepening the financial sector should be developed.
