The authors summarized the social consequences of war upheavals in the Ukraine’s economy. This made it possible to determine the elements and principles of ensuring social stability in the Ukrainian post-war society. The theoretical and methodological approach of social security was deepened with the elements of the policy of social quality and inclusiveness, which should ensure the effectiveness of public governance in post-war development. It is proved that in the pre-war period in Ukraine, no system was created that would correspond to the consensus model of the societies development, social goals of the Association Agreement between Ukraine and the EU; and should ensure a balance between the state’s economic capabilities and the population expectations regarding well-being and quality of life. The reason for this phenomenon was insufficiently effective public governance and low institutional capacity of the state and social development of Ukraine. The article summarizes ways of minimizing the consequences of war upheavals, overcoming military shocks and strengthening Ukrainian social security through policies in three key areas: employment; social protection and macro-financial stability. Special attention will be needed to develop the potential of the national social protection system in accordance with the ILO experts’ recommendations on increasing the share of social expenditures in Ukraine as a country with lower average incomes.
