ENThe internationalization practice of financial institutions has been intensively studied since the 1960s. Due to increase in international capital flows, foreign direct investments and international trade at that time active development of international or crossborder banking began. At present the world is undergoing a very complex process with a high uncertainty in the global banking and financial markets. This article focuses on the banking sector development and some aspects of management of commercial banks in the Baltic States. The main subject of the article is comparative analysis of the inwards and outwards development in international banking. The main stress is placed on aggregated credit enlargements in the Baltic States during the first decade of the 21st century. During the last global economic crisis commercial banks have been looking for a possible optimization of activities and consequently changes in their networks could be an option for the assessment of their development. However the priority could be to identify the crossborder international credit expansion in the Baltic countries. On the other hand these activities rely on the countries' macroeconomic indicators, mainly to the accumulated money supply. There is a scientific selfdetermination described in this paper in line with an analysis of identifying the particular Baltic countries in the dynamics of accumulated deposits and credits of international banks. Subsequently it increased the money supply growth. Nowadays banks are required to make sensible strategic decisions in order to maintain sustainable banking businesses in the future. However influences of the financial institutions to the global economic recession affect international banks creating the negative feedback to their previous problems. Keywords: International banking, central banks, Baltic States, sustainable credit expansion, money supply. [From the publication]
