The relationship between sovereign credit rating and trends of macroeconomic indicators

VUСA is a chaotic and rapidly changing business environment that, based on the variability, uncertainty, complexity and ambiguity of the modern world, transforms the approach of banks to the analysis of financial stability. The aim of the paper is to improve tools for monitoring the impact of VUCA-world conditions on the financial stability of banks, namely a model for studying and analyzing the impact of the modern business space “VUCA” on the financial stability of the country's banks. To test the model, the method of constructing regression equations in multifactor regression analysis is used. For this study, data from some Eastern European countries (Ukraine, Belarus, Latvia, Lithuania, Moldova) were used, and time series data were used for 10 years from 2010 to 2019.
Having considered the definition of “VUCA-world conditions”, the model of modern business space “VUCA” was developed when analyzing the activity of banks in the studied countries. Drivers, consequences, requirements and macroeconomic indicators of the countries’ activities in the VUСA-world conditions are determined. The VUCA-world conditions also consider the study of key macroeconomic indicators that allow building long-term relationships throughout the value chain. The analysis of the studied Eastern European countries showed that with the increase of factors of GDP growth, GNI per capita growth, research and development costs, foreign direct investment, and net inflow of 1%, the effective ratio of bank capital and assets also increases. The assessment, in contrast to the existing ones, makes it possible to consider the impact of the macroeconomic environment of banks on their financial stability.

The banking system guarantees the economic strength of the country. Its sustainability is due to the sustainability of the credit portfolio. Therefore, scientific research on banking risks is always relevant. Basel recommendations and central bank regulations provide risk minimization in case of default of borrower by creating risk reserve, but the high range of macroeconomic factors creates a basis for creating credit risk. The model, which determines the risk factors, may be structurally the same, but the quality of the influence of factors is different in various countries. The influence of macroeconomic factors is particularly evident in developing countries. The impact of economic factors in different countries is high in GDP of these countries. The article focuses on determining the influence of macroeconomic factors on credit risk of systematic banks in Georgia. The coefficients of individual macroeconomic indicators are calculated by using Pearson’s correlation. The credit risk ratio is taken from the bank’s overdue credits and credit portfolio ratio. Based on the correlation coefficients obtained, the expected risk of shock changes is calculated.

The crisis in the political and economic spheres in Ukraine has led to an aggravation of macroeconomic imbalances, which in turn worsen the socio-economic situation, complicate the moments of doing business, manifestation of violations and instability in the public administration sector and social tension in society. As the result is the accumulation of macroeconomic imbalances to a critical point that threatens the normal, gradual development of economic processes that should take place in the economic space of Ukraine. The article deals with the main imbalances indicators of the country's economy and their applicability under modern Ukrainian economic policy conditions. The interconnection of the main macro-instability factors in Ukraine economy and other countries of the world is considered, which allows to identity a number of endogenous (external) and exogenous (internal) factors that create imbalances. The mechanism of imbalances detection is proposed, which combines certain categories, methods, principles and methods of their research. The simulation model for identifying macroeconomic imbalances in the Ukrainian economy was developed, based on which the dynamic properties of the macroeconomic imbalances system were investigated, a short-term indicators forecast was constructed, and assessment of the imbalances probability in the future was implemented. Forecast macroeconomic indicators were estimated that fall into critical areas also the gross external debt, changes in the real effective exchange rate, changes in the share of the export market show that external imbalances and disproportion exist. Other macro indicators that form the imbalances table, according to projected calculations, show trends that are close to the ultimate limits and instability risks which confirms the vulnerability of the country's financial and economic system. The obtained forecasting results will allow to prevent new imbalances through the timely and appropriate rapid response management action.
