Nowadays one of the relevant problems of economic development of Ukraine is the excessive increasing of the public debt that has a number of negative consequences for the financial system of the country. The article is devoted to the research of state’s debt sustainability concept. Special attention is paid to the development of an effective system of debt sustainability management. The aim of the article is to study the theoretical bases of the state’s debt sustainability, investigate scientific and methodological approaches to its management, analyze the public debt and debt sustainability of Ukraine. In order to achieve that goal, the following scientific methods were used: analysis and generalization, decomposition analysis, comparison and compilation. The authors analyzed the structure of the debt sustainability management system: objects, subjects, key principles, objectives, methods, instruments, etc. The list of key indicators of debt sustainability was substantiated and the authors compared their normative values in Ukraine and in world practice. Besides, the state and structure of public debt and the ratio of government debt to GDP were scrutinized. The obtained results proved the debt crisis deepening in Ukraine.

During the post-Great Recession period, macroeconomic stability had more often been threatened by socioeconomic shocks due to the rising of public discontent with the high unemployment rate and poverty, the activation of radical parties and movements, and the aggravation of the geopolitical confrontation in the world. Depending on the type and depth of such shocks, they become politically generated shocks and, in particular, affect the monetary sphere. The article investigates three types of politically generated shocks and their impact on the monetary sphere. It has been found out that the shocks generated by political populism are characterized by fiscal domination in the economy, the use of monetary measures in the budget deficit financing. Shocks arising after the use of international sanctions against certain countries have an external origin and primarily cause the increase in national exchange markets volatility. On the whole, macroeconomic and, especially, monetary instability is the result of the great shocks for the economy, the depth and duration of which are determined by the nature of the crisis, particularly, when country participates in the military conflict. The aforementioned types of politically generated shocks are analyzed based on the experience of countries such as Argentina, Turkey, and Ukraine, which at one time introduced the regime of inflation targeting in monetary policy, but were forced to modify it influenced by political and economic instability.
