The object of research is the current global experience of regulating the financial sector and financing the costs of military actions of countries that were at war. This experience is compared in the work with those measures that were used by the government of Ukraine during the russian-Ukrainian war. In the conditions of war, the problem of financing war expenditures and balancing the budget for uninterrupted implementation of social payments is particularly acute. A sharp imbalance of the country's budget in the direction of financing military expenses and a drop in GDP, as a result of military operations on the territory of the country where military aggression is taking place, requires adequate actions of both regulatory and investment nature from the government and regulators. The timeliness and adequacy of such actions is a practical and scientific dilemma, the solution of which lies partly in the world's historical experience. The work proves that the actions of the Ukrainian government and the National Bank of Ukraine during the active phase of military aggression on the part of russia fully correspond to modern theoretical and methodological achievements in the organization of financing the defense expenditures of belligerent countries. Ukraine is using almost the entire arsenal of possible financing options: reducing non-military spending, increasing government borrowing, and issuing money. The study of the role of expenditures to fill the budget demonstrated the reduction of the role of taxes as a lever for financing the growing expenditures of states on defense. Coordinated actions of the Government of Ukraine and the National Bank of Ukraine prevented a sharp outflow of foreign capital from the country and preserved the purchasing power of the national currency. This is explained by the timely application of historical experience, tools of the classic Lucas-Stokey model with skillful manipulation of government debt rates in order to interest investors in long-term investment in government debt securities, and unprecedented financial assistance from foreign partners.
