Germany could create a parallel currency—a new D-Mark, pegged at 1.0 to the euro. The German government would guarantee that holders of German government bonds could convert euro securities to new-D-mark instruments on a one-to-one basis up to some designated date, perhaps two years in the future. Private German contracts expressed in euros would switch to new-D-mark claims over the same period. The transition would likely feature a period in which the euro and new D-mark circulate as parallel currencies.

Other countries could follow a path toward reintroduction of their own currencies over a two-year period. For example, Italy could have a new lira at 1.0 to the euro. If all the euro-zone countries followed this course, the vanishing of the euro currency in 2014 would come to resemble the disappearance of the 11 separate European moneys in 2001.
