Research included six Western Balkan countries (Albania, Bosnia and Herzegowina, Macedonia, Serbia, Montenegro, and Croatia) in the period 2001-2012. The analysed data entailed economic growth rate, saving shares, investments and current account deficit in gross domestic product and especially the data about the dynamics of direct foreign investments in the given time frame. The conclusion reached is that one of the necessary requirements for economic growth of the countries in this region in the forthcoming period is growing share of national sources, that is to say growing share of domestic savings in gross domestic product. Especially since it is well-known that foreign funding sources in the form of foreign direct investments in privatization of state-owned companies have nearly disappeared.
