Financial system supports economic growth, while its regulatory framework provides stability for investors. Develo-ping countries with bank-oriented financial systems are not attractive to investors, so prolonged status quo leads to economic deterioration. This is particularly the case with some of the most underdeveloped areas in Europe: Western Balkans. It is essential the developing countries in this region consider steps towards financial liberalization, which will help open the borders for capital flows and attract new investments. The main goal of this paper is to review and present the available information related to the banking system development in Western Balkans in terms of ownership structure, capital adequacy, loan and asset performance, return on investment and liquidity. These indicators should provide a clearer picture of the current financial systems in Western Balkans economies and their development progress – useful for comparison with other developing regions and financial transformation and liberalization efforts.
