The decision of establishing a single currency was also seen as a tool for integration and unity. Basically, the idea of a single currency was a tool for fighting back rising nationalism at that time which was not beneficial for the countries. A unified currency in the EU benefited the states mostly in the area of trade. Trade system in EU does not apply any taxes when it comes to trading between the member states.
