Globalization, the construction of the monetary and economic union and economic crisis represent the trends that European Union is currently facing. The main reason for the introduction of reregulation were the unfavorable effects of the economic crisis. The purpose of the new rules was the protection of European economy and its integrity. The regulation itself is being rated on a supranational level. The last economic crisis has highlighted all the weaknesses of the current level of integration in the EU and has showed that changes in the monetary and fiscal policies, as well as the strengthening of their interaction, are necessary if smart, sustainable and inclusive growth want to be achieved. The actions taken by the Union are represented by the design of the financial architecture of stability and the establishment of institutions such as the European Financial Stability Facility (EFSF), European Stability Mechanism (ESM) and European Financial Stabilisation Mechanism (EFSM). Furthermore, higher level of supervision on monetary financial institutions of the EU has taken place through the establishment of banking union whilst the ECB has abbandoned its neutral position of the observer and has started actively participating in the battle against asymmetric shocks. The next challenges of the EU are forming the capital markets union and fiscal union, but those steps require political courage and consistency if greater degree of integration and European unity want to be reached.
