"By trying to move prematurely to monetary union, we would run very serious risks. The dangers of forcing the pace have been amply demonstrated in Germany. Karl Otto Pohl, the director of the Bundesbank, has described Germany's experience as "a drastic object lesson" of the need for prior convergence before establishing a currency union. Reunification there has meant the rapid merger of two very different economies. The short-term consequences are a huge rise in the German budget deficit and rising unemployment in eastern Germany, but for the rest of the Community their experience is salutary. It shows the strains and tensions set up by moving to currency union before there is proper economic convergence. In the case of Germany one strong currency and one strong economy effectively took over those of a weaker neighbour. How much greater would those strains and tensions be if 12 very different states with different economies were now to adopt a single currency?"
