    The current thesis explores the way in which bank profitability was influenced by the introduction of the Single Supervisory Mechanism (SSM), the first pillar of the European Banking Union. On the one hand, increased transparency and credibility were expected to improve profitability, while, on the other, adjusting to a burdensome supervisory regime was thought to hinder it. Focusing on a sample of directly supervised banks by the SSM and a sample of banks still supervised by the National Competent Authorities, over the period 2011-2017, this thesis examines the net effect of the SSM introduction on the evolution of bank profitability indices, and in particular the Return on Assets (ROA) and the Return on Equity (ROE).Chapter 1 briefly describes the emergence of Banking Union within the EU financial sector and its interconnectedness with bank profitability.Chapter 2 examines whether the establishment of the SSM influenced the profitability of the directly supervised banks in a different way, contrasted to the influence on the profitability of the rest of the European banks. The difference-in-differences methodology is employed and the main results indicate a positive effect of the SSM on bank profitability. In Chapter 3 this positive effect is further analyzed, using unconditional quantile regression analysis, in order to test for asymmetrical effects throughout the bank profitability distribution. Chapter 4 examines whether and to what extent the implementation of the SSM led to profitability convergence of the euro area banks, using the Phillips and Sul (2007) panel convergence methodology. In addition, the tests for β- and σ- convergence are conducted as an alternative approach.
