The accession of Serbia to the European Union should bring stability, peace, justice, freedom and security to the Balkans. In this regard, strengthening the competitiveness of the country's economy in order to improve its ability to withstand the pressure of the competition in the single market and reduce unemployment through job creation is the most important objective of Serbia's economic policy. The purpose of the paper is to provide a short overview of the achieved results in terms of foreign direct investments in Serbia and to determine them as a crucial factor in increasing the country's competitiveness. The paper stresses expectations that the outcome of negotiations with the EU will improve the investment plans in Serbia and, consequently, create conditions for a stable financial and macroeconomic environment.

The banking sector is one of the most prospective sectors for foreign investors in Serbia, which was especially observed during the period of 2004-2011.
