但在金融乱局中引人一个全新贬值的国家货币来代替欧元则是完全是另一回事情，绝大多数经济学家对此一无所知。 回顾历史，和这个最为接近的恐怕是2002年的阿根廷退出锁定美元的汇率机制（连系汇率制度）自由浮动，阿根廷比索在头三个月内就贬值了300 % 。
The closest experiment along these lines is probably Argentina’s exit in 2002 from its dollar exchange-rate peg (embodied in its currency board) to a floating regime that depreciated the peso by 300% in the first three months.
