The article is devoted to the topical issues of long-term lending to public-private partnership projects in the context of a permanent shortage of budget funds and the financial instability of business entities. The purpose of the study is to highlight the problems of attracting long-term credit resources by partners in the process of implementing joint projects and to outline areas for their solution. To achieve this goal, general scientific research methods and analytical data from the State Statistics Service of Ukraine and the National Bank of Ukraine were used.The article reveals the main problems in the development of the debt financial instruments market, which make partnership projects between the state and business unattractive for investors. It is argued that the possibility of providing long-term loans depends not only on the actions of the bank, but also on the monetary policy of the NBU, which should ensure the introduction of preferential reserve requirements for banks, the provision of irrevocable deposits, the NBU's approval to refinance banks for the implementation of PPP projects, and the introduction of preferential lending by banks to PPP projects. The authors emphasize the priority importance of the state policy on the development of programs for the availability of long-term loans in the process of implementing partnership projects. Given the underdevelopment of financial instruments for public-private partnerships, the author substantiates the need to use innovative instruments – credit derivatives, the effectiveness of which is confirmed by international experience. The article offers a list of the most effective financial instruments that should be used at each stage of the project life cycle.It is concluded that the recommendations provided will ensure that the partners attract the necessary amount of financial resources in the process of long-term project implementation and will allow them to obtain a synergistic effect from such cooperation.
