The term common currency in the Czech Republic is still postponed and there is no interest on the part of the ruling coalition to establish a deadline for the adoption of the euro. Before entering the eurozone need to ask some fundamental questions. One thing is convergence with the Maastricht criteria, the fulfillment of which we should not have a problem and basically already meets all these criteria. But the question remains whether they are the best and the most important criteria that should decide on the approach of our country to the common currency. It is necessary to ask a number of other issues. Among these are, for example, whether the common currency actually benefited economically states who have introduced the Euro. The Maastricht criteria are actually the most important factor with regard to their (non) performance on the part of some euro area countries? It is the convergence of the Czech economy with the euro area economy is high enough, but not in terms of ownership or sectoral structure, but in terms of the convergence of a number of other economic parameters - price, wage parameters. Among the major question also we belong, whether we want further integration and deepening of the integration process, and whether it is in the interest of the Czech economy to abandon its own monetary policy. These are the main questions that must be taken into account when deciding on the suitability of the common currency.
