The inspiration for a banking union was the delicacy of various banks in the Eurozone, and the distinguishing proof of endless loop between credit conditions for these banks and the sovereign credit of their individual home nations. In some countries, the private debts that arose due to property bubbles were shifted to ascendant liability as an outcome of the banking systems bailout and government reactions to moderating economies post-bubble. It is due to the weakening of credit facilities at the time of the Eurozone crisis and fear of financial instability among the member states. This led to the need for interdependence between financial stability, banking policy, and economic integration that saw the need to establish a banking union. Interestingly the banking sector of individual States faces the risk of likely marginalization as other countries in the union are trying to integrate Additionally, the banking union in Europe is immediately needed to revive the stability and credibility of the bank’s system within the Euro area. There has been a continuous vicious cycle of sovereign countries in Europe and the banks themselves. For example, some countries are unwilling to participate in the activities of the Banking Union, for instance, the UK. The sabotage by the UK has made some countries too to wish to exit the Union because of numerous challenges. Europe’s financial banking sector has been going through times of polarised tensions. Starting in 2014, the banking union primarily comprises of two primary activities, the Single Supervisory, and Resolution Mechanism, which are based on the single rulebook , or basic monetary administrative structure. The single rulebook comprises an arrangement of authoritative writings that every single money related foundation (counting more or less 8300 banks) in the EU must agree to. These principles,besides other things, set down capital necessities for banks, guarantee better insurance for investors.
