Sources of financing of expenditures of the State Budget of Ukraine in 2019- 2024, % Indicators 2019 2020 2021 2022 2023 2024 The share of expenditures of the State Budget of Ukraine financed from the following sources: - tax revenues 74,1 65,8 74,1 35,1 30,0 36,7 - non-tax revenues 17,3 16,5 11,7 12,8 24,7 21,8 - grant assistance from the EU, partner countries, donor institutions, international organizations 0,1 0,1 0,1 17,8 10,8 10,6 - other income 1,0 0,8 0,9 0,4 1,1 0,6 - budget revenues (without grant aid) 92,4 83,1 86,7 48,3 55,8 59,1 - budget deficit 7,5 16,8 13,2 33,9 33,3 30,3 Source: built by the author based on [4; 5]. Since the beginning of the Russian invasion of Ukraine, GDP has declined by 28.8%, exports have fallen by 35.0%, and state budget cash expenditures in 2022 amounted to UAH 2.702 trillion, or 92.2% of the budget for the reporting period. The state budget deficit of Ukraine amounted to almost UAH 915 billion. The existence of a significant budget deficit, as international experience and practice show, always leads to greater attraction of additional funds to cover it and an increase in the volume of public debt. Thus, a significant problem of the efficiency of the functioning of the public finance system, which affects the stability of the financial system during the war, was the external debt dependence of the state (Table 2). As can be seen from the data in Table 2, over the past (6) six years, the volumes and, accordingly, payments for servicing and repaying the public debt have increased. Thus, according to the Ministry of Finance of Ukraine, in 2024, compared to 2019, the volume of public debt increased by UAH 4931.1 billion or 73.7%. Also, in 2024 (UAH 1423.31 billion) compared to 2019 (UAH 466.58 billion), payments on the public debt increased by UAH 956.73 billion. Given the high cost of borrowing, public debt
