To join the Eurozone (EZ), a candidate country has to fulfil five nominal Maastricht convergence criteria and ensure compliance of national legislation with the acquis communautaire. With this regard special difficulties pose the fiscal criterion relating to the maximum allowed budget deficit of 3 per cent of GDP. If it is not met, the European Commission launches the Excessive Deficit Procedure. Currently, such formula applies to France, Spain and the United Kingdom. Although the issue is not absolutely certain, one can assume that euro will weather the present difficulties and will come out stronger, though the economically unjustified Euro scepticism of some countries is not helping. It may be expected that in the 2020s the European Monetary Union will be joined by all countries that are still using their national currencies and that the EU will be extended to include new member states, enlarging the euro area further. In this article authors are discussing the issue whether Poland will join the EZ in the coming years, considering the challenges of meeting all Maastricht criteria, on the one hand, and the reluctance of the government to give up the national currency, on the other. A mixed method combining the results of qualitative and quantitative research has been used to empirically verify the research question presented.
