    Mutual Analysis of the Dynamics of Development of the Banking Sectors of Key Countries in Europe, Asia and America
    (IJAAFMR, 2023) Lyashenko, V.; Bitner, I.; Ponomarenko, O.
    The banking sector plays an important role in the economy and development of every country. The banking sector is an important segment of the financial market. Banks normalize and ensure the continuity of the movement of various financial flows between different economical agents. At the same time, banks play an important role in international trade. Banks contribute to ensuring the parity of currency quotes, mutual settlements between countries, and support the movement of financial flows at the international level. For such provision, an important point is the mutual analysis of the banking systems of different countr ies. One of the indicators of the functioning of different banking systems are the corresponding stock indices. We consider the dynami cs of changes in a number of such stock indices for some countries in Europe, Asia and America. We also consider some statistical characteristics of the dynamics of changes in the corresponding stock indices selected for analysis. This allows a better understanding of the functioning and development of the respective banking systems. For analysis, we use the wavelet ideology . We consider the corresponding wavelet coherence estimates. The paper presents a series of graphs and charts that allow you to understand the results of this study. The results obtained allow us to form appropriate strategies for entering the internati onal banking market.
