Nowadays, there is a constant need for managing large amounts of information in public finances to identify existing and prevent future cases of illegal use of financial resources of citizens. The openness of information of key public finance authorities has a powerful anti-corruption effect and has a beneficial effect on economic development, while transparency of public finances is a factor in the successful implementation of the reform of all spheres of the economy.
The purpose of the article is to develop a methodology for assessing the institutional and political transparency of the leading public finance authorities in Ukraine and its practical application on the example of the Ministry of Finance and the State Fiscal Service of Ukraine. The methodology includes six main stages, based on which the transparency index of public finance authorities was calculated. Constant calculations of the index will motivate the interaction of stakeholders and non-governmental organizations to increase the openness of public finance authorities in public finances, and the digital data settlements themselves can be used to develop recommendations to increase the level of transparency of the activities of key public finance authorities. Approbation of the developed transparency index of public finance authorities on the example of the Ministry of Finance and the State Fiscal Service of Ukraine made it possible to calculate the percentage of openness of data published by the indicated institutions. Based on quantitative calculations, practical recommendations were made for improving the completeness, reliability, availability and timeliness of published information.

This study is devoted to assessing the level of individual segments interconnectedness within the financial market of Ukraine (FMU) and their dynamics in uncertain conditions. The methodology of the systematic approach is used to investigate the dynamic relationship between individual segments of the financial market of Ukraine, namely credit (deposit-credit) market, stock market (market of securities), government securities market, currency market, and interbank market. The study of financial market dynamics focuses on the description of the price indicators of individual market segments, which are monitored using time series analysis and statistical methods. The results of the time series assessment revealed the fractal characteristics of the Ukrainian financial market as a measure of sustainability (namely inertia). It is revealed that all segments of the financial market, except credit, are characterized by persistence. It is established that the development of market segments is uneven and is characterized as bifurcation. The credit segment is addicted to insider behavior and has the highest risk concentration. It is revealed that the foreign exchange market is still in crisis. The results of modeling the correlation relationships between market segments have shown that, in the presence of such relationships, they differ in the strength and nature of the interaction. They are volatile, unstable, and situational, dependent on external conditions. The credit market has a relationship with other segments, not significantly strong but stable. The results of the analysis indicate the dynamic development of segments within the Ukrainian financial market in the presence of interconnections between them.
