This paper examines the effectiveness of economic sanctions imposed on Russia, particularly following its 2022 full-scale invasion of Ukraine. Despite the unprecedented scope and scale of these sanctions, their impact on Russia’s economy has been mixed, with only moderate contraction reported by official Russian statistics. It combines an empirical assessment of these sanctions with the development of a theoretical framework to better understand the complexities and trade-offs in their application. Sanctions, while a critical tool of economic statecraft, are not a guaranteed solution to end wars or alter a country’s behavior. The efficacy of sanctions depends on factors such as the target country's size and global integration, the sanctioning coalition's unity, the ability to enforce sanctions, and the economic burden on sanctioning nations. The paper underscores the importance of realistic expectations and careful design of sanctions policy on trade, finance and payment systems.
