If one looks for issues that divide the Visegrad Group (V4), membership in the European Monetary Union (EMU) is definitely one of them. While Slovakia joined the common currency area in 2009, Czechia, Hungary, and Poland have remained reluctant.
This study reviewed whether Slovakia's experience with euro adoption could reduce or strengthen their scepticism. Slovakia's economic performance after it become an EMU member can be perceived as at least satisfying in terms of growth, unemployment, and macroeconomic stability, despite the severe economic and financial crisis in the eurozone.
This explains why Slovaks are actually quite happy having the euro. This positive experience could indeed be a factor in debates on the euro in other Visegrad members.
However, the study found these same states' economies performed not significantly worse or even better than Slovakia in the period between 2009 and 2017.
