Current empirical literature concerning foreign bank entry and case studies conducted in different countries, shows that the foreign bank entry causes negative impact on their domestic competitors performance. Basically, due to the improvement of the competitive market structure and better banking practices introduced by foreign banks, the domestic competitors are compelled to reduce their level of profitability and net interest margin (spreads), enlarge their credit intermediation, improve their operational efficiency, and increase their amount of risk, resulting in higher loan loss provisioning. By using semestral data from 11 private Brazilian banks during the period of 1994 - 2002, and conducting panel regressions and linear multivariate regression for the aggregate data of the sample, this work aims at offering evidence of a statistic relationship between the extent of foreign entry and ownership in the Brazilian private banking performance. This work show that in Brazil, the foreign bank entry, stimulated by the economic liberalization of the Real Plan and reforms taken under the legislative framework, had little impact on the Brazilian private bank performance, which contradicts the empirical evidence in the literature. Estimation results suggest that an increase in the share of foreign banks leads to higher profitability, lower operational efficiency and higher loan loss provisioning of domestic private banks.
