24 deficit was observed. And, the state budget, as a component of the public finance system, reflects the main financial indicators that ensure, among other things, support the stability of the country's financial system. Thus, in 2013-2014, the deficit was 4.45% of GDP and 4.98% of GDP, respectively. As we can see from the data in Table 1, since 2011 and in fact to the present time, the deficit has become a chronic phenomenon. As international experience shows, in some cases, a chronic deficit can lead to rapid default. In 2014, the decline in the economy and financial instability was the result of russian aggression in eastern Ukraine ( due to the occupation of certain parts of the Donetsk and Luhansk regions and the Autonomous Republic of Crimea ). However, being in extremely difficult conditions, the then government restrained the growth of public debt and ensured the financial stability of the country. In 2020, the state budget deficit amounted to more than UAH 217 billion or 5.18% of GDP, and in 2021 this figure amounted to 3.63% of GDP, i.e., it decreased by 1.55 percentage points compared to 2020. With the full-scale invasion of Russia into the territory of Ukraine, the situation became even more acute. Since the deficit of the State Budget of Ukraine in 2022 amounted to almost 915 billion UAH or 17.62% of GDP. This was actually the highest indicator of the budget deficit and its share in GDP, if compared with the pre- war period. However, during the hot phase of the war in 2023, this indicator increased by another 2.77 percentage points compared to 2022 and amounted to 20.39% of GDP or 1.33 trillion UAH. Already in 2024, as can be seen from the data in Table 1, the budget deficit amounted to 1.35 trillion UAH or 17.74% of GDP, i.e. decreased compared to 2023 by 2.65 percentage points. However, in 2025, the budget deficit increased again compared to 2024 to UAH 1.63 trillion or 18.32% of GDP, i.e. by 0.58 percentage points. Analysis of the share of the budget deficit in GDP during 2011-2021 indicates its unstable state in peacetime, which averaged 3.11% of GDP. However, in the war period of 2022-2025, instability increased and the generalized average indicator is 18.52% of GDP, i.e. increased by 15.41 percentage points compared to peacetime conditions. This gives grounds for concluding that with the increase in instability
