Greece crisis proves the need for a currency Plan B

Introducing an alternative currency is not particularly difficult as long as the fundamentals of currency design are understood by its architects

The recent Greek capitulation under pressure from other euro member countries, led by Germany, demonstrates that euro members have de facto ceded sovereignty over fiscal policy to the EU. While this arrangement may be acceptable to some countries, perhaps even Greece, it will be resisted by others.

However, as the Greek failure also demonstrates, any eurozone country wishing to restore fiscal sovereignty, or restructure some of their debt, or implement any policy or set of policies that runs afoul of the preferences of certain Eurogroup finance ministers will have near-zero negotiating leverage if they fail to plan, credibly and in advance, for the introduction of a viable alternative currency.
