Importance The expansion of financial instruments like revolving funds in developed countries was associated with extensive government intervention in the economy after World War II. This influenced the development of the economic functions of the State bodies and State organizations. Despite the fact that the Russian Federation has examples of revolving funds at regional and local levels, these funds did not find any application as budget financing tools as opposed to some developed countries. The article discusses the practice of revolving funds implementation in Canada and the United States of America. Objectives The objective of the study is to analyze practical application of revolving funds within the budget sphere of the countries where this kind of practice has become most widespread, i.e. Canada and the USA. Methods We analyzed the practical use of State revolving funds in Canada and the USA under the comparative analysis method.
