The purpose of this study is to analyze the deposit banks’ performance in Turkey in terms of their ownership structure with the help of financial indicators and to determine the indicators that best discriminate the ownership structures of the bank groups as to whether they are privately owned or owned by foreign capital or state. In the first part, by using principle components analysis, performance indexes are developed for deposit banks according years. According to these indexes, it is observed that foreign banks were generally more efficient than privately owned and state owned banks. Stepwise multiple discriminant analysis results showed that the thirteen of the sixty-seven indicators achieved the optimal level of discrimination between the ownership groups. The top three indicators that contribute most to the discriminating process are respectively; the interest expense to total expenses ratio (G13), total deposits to total assets ratio (BY8), personnel expenses and reserve for employee termination benefit to number of personnel ratio (FO2). On the other hand, it was confirmed that liquidity and profitability indicators do not have any contribution to discrimination. According to the results of the analysis banks are classified at 90.6% accuracy level according to their ownership groups by stepwise multiple discriminant analysis.
