Dissolution of the Euro? Not likely

As Barry Eichengreen notes:
[I]f a participating member state now decided to leave the euro area, no such precommitment would be possible. The very motivation for leaving would be to change the parity. And pressure from other member states would be ineffective by definition.

Market participants would be aware of this fact. Households and firms anticipating that domestic deposits would be redenominated into the lira, which would then lose value against the euro, would shift their deposits to other euro-area banks. A system-wide bank run would follow. Investors anticipating that their claims on the Italian government would be redenominated into lira would shift into claims on other euro-area governments, leading to a bond-market crisis. If the precipitating factor was parliamentary debate over abandoning the lira, it would be unlikely that the ECB would provide extensive lender-of-last-resort support. And if the government was already in a weak fiscal position, it would not be able to borrow to bail out the banks and buy back its debt. This would be the mother of all financial crises.

If any state were to leave the Euro first my bet would be Spain or Italy. Italy especially.
