5 Conclusions and Discussion
In this study we aim to analyze the efficiency of publicly traded banks for the period 2006-2012. To fulfill this goal we have used the specialized CAMELS ratios. According to the findings of the study, the best scores of the total of the banks happened in the period 2006-2009. In particular, 2007 is considered the best year graduated. From the analysis of profitability ratios (ROE, ROA) and liquidity (L1, L2) of the above period shows increased profitability and liquidity of banks, which is mainly due to the expansion of their activity in housing and consumer credit, as well as to their international activity which during the same period was very strongly developed. The capital adequacy of the banks is displayed enhanced in the same period and the quality of their loan portfolio is considered satisfactory. The contribution of banks to address the economic crisis in their participation to PSI affected adversely their profitability. On the basis of our findings, the period 2009-2012 was the worst in their grading. In particular, the year 2012 turned out for the banks the worst year. The banks recorded losses (before-taxes) of approximately 38 billion euro during 2012. These losses had a serious impact on equity funds. The ratio analysis reveals that the banks have been weakened in capital adequacy while both their profitability and liquidity have been seriously damaged. One major problem for the banks during this period is the splash of loans overdue for more than 90 days. The performance of the banks in relation to the treatment of market risk is notable. From the low values of the ratio throughout our analysis we can see that the banks were not highly exposured to market risks. Besides, the index administration also seems to keep graduated at low levels even during the crisis, which is mainly due to the efforts made by banks for rational management and cost reduction
