The article developed a basic simulation model of diversification of foreign economic interactions, which makes it possible to assess the mutual influence of key economic indicators and their reaction to changes in the equilibrium in world markets. The peculiarity of the developed model of diversification of foreign economic interactions is its functioning as a complex dynamic system in which many factors are interrelated, and the connections are dynamic. This makes it possible to calculate a simulation model that takes into account hidden and subtle connections. While modeling foreign economic interactions and evaluating the influence of various regulators on them, in addition to the stage of model development itself, mandatory parameterization of this model is proposed, that is, the determination of specific types of dependence between the factors included in the model and the parameters of these dependencies.
The implementation of this model can be carried out in any simulation package.

Modern development of banking business is connected with significant risks, which, taking into account globalization processes, political, economic problems in Ukraine and worldwide, development of technological and information systems, tend to transform, therefore it is very difficult to identify them and take preventive measures concerning their smoothing. Taking the abovementioned into account, it is reasonable to assess the modern state of risk management in the activity of Ukrainian banks and the influence on banking system development. For this purpose, the authors analyzed the performance of Ukrainian banks in the period 2017–2018 based on official statistic data of the National Bank of Ukraine and measures of economic standard of banking activity; studied the modern state of performing risk management in Ukrainian banks. The authors offer the process of effective organization of risk management system in national banks, which is a prerequisite for safe management of the bank. During the study, the authors found the significant decrease in the share of credits in total assets of Ukrainian banks and low quality of assets of Ukrainian banks during 2017–2018. This is caused by the significant amount of loan arrears, during the study period, the amount of loan arrears in 2016 increased by 36 times in comparison with 2008. The authors point to the need for improvement of assessment of banks’ riskiness, as a result of which they offer to use the methods of descriptive statistics for assessing risks and identifying them at all levels of banking activity.
