In connection with the termination of the Czech National Bank's interventions, the debate on the adoption of the common currency has again developed. However, the widespread public opposition to the common currency is becoming more and more pronounced, and nowadays it would like the common currency according to a survey of around 20% of the population. The economic problems of Greece, Italy, and Spain are right. From the point of view of the economic criteria, the Czech Republic fulfills these criteria without any problems. You have to ask a whole bunch of other questions. These include, for example, whether the single currency actually benefited economically those countries that have the euro in place. Are the Maastricht criteria really the most important factor in terms of their (not) fulfillment by some euro area countries? The fundamental question also is whether we also wish to further integrate and deepen the integration process and whether it is in the best interests of the Czech economy to renounce its own monetary policy. These are the main issues that we must take into account when deciding on the appropriateness of the common currency.
