The purpose of the article was to investigate the sources, structure and mechanisms of financing the development of Ukraine’s water infrastructure under conditions of full-scale military actions, as well as to substantiate directions for improving the financial provision of the sector in the context of post-war economic recovery. Particular attention was paid to assessing the role of state financing, international financial assistance and public-private partnership mechanisms in ensuring the functioning of river and port infrastructure. In the course of the research, a set of general scientific and specific methods was employed, including methods of analysis and synthesis, statistical analysis, comparison, generalisation, and systemic and institutional approaches. The informational basis of the research comprised Ukraine’s regulatory and legal acts, statistical materials of state authorities, reports of international financial organisations, as well as the results of scientific research in the field of transport and water infrastructure development. The results of the research established that in 2020-2024 there was a substantial increase in the volume of financing for Ukraine’s water infrastructure, which was driven by the need to ensure alternative logistics routes under conditions of the blockade of part of the seaports. In particular, the total volume of state financing of the sector grew from UAH 470 million in 2020 to UAH 2.77 billion in 2024, while international assistance attracted in 2022-2024 exceeded USD 500 million. The main sources of financial provision of the sector were identified, including the state budget, international financial assistance and investments attracted through public-private partnership mechanisms. The growing strategic importance of Danube ports and inland waterways in ensuring export activity and maintaining the state’s economic resilience was substantiated. The scientific novelty of the research lies in a comprehensive assessment of the current structure of financing Ukraine’s water infrastructure under martial law and the identification of the features of the interaction between state, international and private financial resources in the processes of its development and recovery. The practical significance of the results obtained lies in the possibility of their use by public authorities, economic entities and potential investors in developing programmes for modernising water infrastructure and forming an effective financial policy in the field of transport logistics
