Although Ukraine’s economy is still suffering from the negative effects of Russia’s full-scale invasion, questions are already arising about the possibilities of ensuring its post-war recovery, so it is important to study the policy instruments to achieve an effective recovery. The purpose of the study was to analyse the existing public policy instruments and identify those that would allow for the most effective recovery of Ukraine’s post-war economy. The main research methods used were analysis, forecasting, and abstraction. The study examined a large number of policy instruments that could be used in the post-war reconstruction of Ukraine’s economy. They covered both financial and social components aimed at facilitating recovery and ensuring long-term stability. The paper provides a comprehensive overview of the policy instruments and their characteristics, emphasising the importance of their use in the post-war period. Special attention is paid to the issues of economic stability, which was also proposed to be achieved by working on two separate components: economic and political stability, and recommendations for achieving them using certain state instruments were provided. Economic diversification is highlighted as a separate factor that plays an important role in the long-term development of the country and is a critical part of building the resilience of the Ukrainian economy after the war. The work brings new knowledge to the analysis of public policy instruments, which will allow to build a more effective strategy for rebuilding the Ukrainian economy in the post-war years
