Wavelet Coherence as a Tool for Assessing the Functioning of the Banking System (on the Example of Data From Ukraine)
Vyacheslav Lyashenko, Inna Viadrova, Irina Bitner

Abstract:
An efficient banking system is one of the factors for stable economic development. The ability to accumulate and redistribute financial resources contributes to the development of the economy and the financial sector. The stability of the functioning of the banking system contributes to the attraction of resources from such a source as the population. At the same time, it is important to analyze the functioning of the banking system in difficult conditions of its development: during the period of economic transformation, the influence of a set of various negative factors. Various methods and approaches are used for this analysis. The functioning of the banking system is described by various indicators and data sets. This reveals and shows the effectiveness of such a system from different points of view. Therefore, it is important to analyze the mutual dynamics of various characteristics that describe the functioning of the banking system. It is noted in the work that for such an analysis it is advisable to use the ideology of wavelet analysis. Wavelet coherence was chosen among the methods of such analysis. The use of wavelet coherence made it possible to construct an assessment of the functioning of the banking system on the example of data from Ukraine. For this, various data sets are considered, which reflect the functioning of the banking system from different points of view. On the basis of such assessments, the effectiveness of the functioning of the banking system of Ukraine has been analyzed. Results are presented based on real data analysis. This allows us to speak about the practical significance of such results, the possibility of their application for solving practical problems. Data and analysis results are presented in the form of informative graphs and diagrams. This allows us to understand the logic of the results obtained, to repeat this study and make similar assessments.
