The continuity of such contracts after the introduction of the euro inside and outside the EU was the subject of extensive legal studies. However, in the end, and perhaps also as a result of a provision in the EU Council’s euro Regulation, legal problems did not arise in this area. This does not mean that there is no need for further legal convergence.
On the contrary, having built a solid house for the euro, refinements in its furbishment remain, of course, a matter for attention. Such refinements will no doubt follow the evolutionary path as described earlier, with attempts being made to strike a balance between the need for unification and the wish to maintain national differences.
