Is banking union suitable reaction on recent financial crisis?

In reaction on the financial crisis 2007-2009 was introduced by the European Union a concept of banking union that should prevent similar destabilization of financial markets and readjust supervisory and regulatory mechanisms to reality of the European banking sector. The aim of the master thesis was to assess the concept of banking union as a suitable reaction on current state of the financial sector. The thesis includes historical discourse on banking regulation with an emphasis on institutional framework and requirements on banks. It introduces individual pillars of banking union -- Single Supervisory Mechanism, Single Resolution Mechanism and Single-rule Book. The comparative analysis of selected indicators of each individual Eurozone banking sector proved significant disparities. Based on the proven heterogeneity of banking sectors and institutional shortcomings of the banking union the conclusion was reached, that operation of single supervision and regulation can lead to adverse effects either on banking markets or on economies of member states and therefore it is rendered as an unsuitable reaction on current developments of the European financial markets
