Ukraine chose the path of European integration and became a candidate for membership of the European Union. This made it necessary to adjust the national economy and social sphere to the European standards. The financial market is an active participant in European integration processes, especially during the period of reboot of the national economy. First of all, the subjects of the financial market are the state, business, citizens, that all are economic agents who enter into financial relations as regulators or objects of regulation, investors or consumers of investment resources. The war unleashed by Russian Federation in Ukraine leads to significant destruction in all sectors of the national economy. Reconstruction will require significant financial resources, which will be attracted from various sources. At the same time, the financial market of Ukraine will certainly become one of the most important elements of the reconstruction of the national economy, business and social sector. Ukrainian citizens will also be involved in investment processes, but for this they should know the basics of investment mathematics, financial technologies, and financial literacy. In addition, financial institutions are reluctant to invest in the agricultural and industrial sectors of the economy. The cost of credit resources is too high, and the level of business profitability does not pay off the resources involved. In this context, the subjects of the financial services market, in particular banks and insurance companies, should introduce the principles of social responsibility of financial business to society in corporate governance. Very important issues of today, which are highlighted in the monograph, are the restoration of budgetary stability and debt security of Ukraine in the post-war period, improvement of monetary and budgetary policy aimed at macroeconomic stabilization in the country. The authors emphasize the tools that can ensure anti-crisis regulation of the banking system, financial business management, since banks play an important role in the activation of investment processes during the reconstruction period. In addition, it is necessary to develop business in the production sector of the economy. The monograph examines the issues of ensuring the economic security of the construction industry, directions for improving the accounting policy in the field of business as a whole, and improving the quality of audits. This should ensure quick adaptation of Ukrainian business to international accounting and certification standards. These and other aspects of the current problems and priority directions of the development of the financial market are devoted to the monograph of the team of authors who carry out up to date researches within the scientific school of the National University "Yuri Kondratyuk Poltava Polytechnic".
