The EU’s monetary approach is specific and complex equally in the historical sense of including the previous ‘monetary snake’ (1971-1979) and (especially) ‘European Monetary System’ (EMS 1979-1999) phases. In such an order, the common currency wouldn’t be able to arrive without such precedents. And since admitting this, other aspects come up to change a bit old judgments about the European integration: (1) the (economic and) monetary union phase rejects the old Balassa’s model view through finding a longer time strategy approaching (1971-2002); (2) the common-unique market also stops being an ‘intermediary’ phase, by becoming a real ‘trunk’ of a larger second phase, that is the ‘advanced integration’; (3) the last, as distinct from the earlier or ‘incipient’ integration phase and both ‘incipient’ and ‘advanced’ integration phases in junction make the real difference between the European (EU) and all the other integration States formations there currently are and were so far existing world-wide.
