Quote from Ed Breen:
Ghost, Greece and now Spain are out of the credit markets now. When you take IMF or EFSF money that money gets a priority and you lose your access to public markets, becuase public investors don't want to be subordinated. That is why the Spanish bank bail out is falling apart in its first day.
All the countries you cited that went through a devaluation had export economies and natural resources that were the basis to obtain hard currency and post collateral for new credit. Greece has no such assets, their main source of hard currency is tourism and that may not do so well when they are in general domestic chaos.
Whenever a currency collapses, such as during the Weimar in Germany and Austria and in the modern case of Zimbabwe, the private sector refuses the domestic sovereign currency and will only accept foreign currency. Today, Zimbabwe uses the U.S. dollar for its currency in trade. When a currency collapses the only people who will take the currency is the Government and its employees becuase they have to...and they try to get rid of it as fast as possible.
My comment above assumes that Greece would change to the Drachma, probably at 1 to 1 bases. Then the market would value the drachma immediately at about 50% of the Euro...and then from the very begining the discount will grow because the Greek Government will have no access to foreign currency...because it has no export assets and it has no credit. Its businessess and social structure will be in chaos, so nobody is going to come in and set up a factory...hell tourists will be loath to come...foreign investment will not come to the rescue. Given that they are already shut out of the public credit markets it is not likely that those markets will open up when they default, devalue and collapse. They would be better off if they defaulted and stayed on the euro.
