I see countries wanting to join the Euro but non wanting to leave. My view is that there is nowhere to go for the countries in the EMU. Even if they default on debt. I dont think it is possible to go back to the punt or peseta or drachma. The markets would crush them. The Germans and French will not allow the other EMU countries to inflate their way out of debt like the UK and USA. The Germans in particular are aware of the consequences. I also think that Sterling is going to suffer and the UK could go bankrupt. The Euro will probably do reasonably well because of the complicated nature of the European Union. USD will stay strong in the short term, being the world reserve currency. Long term I see it coming off badly and eventually being replaced as the reserve currency.
I think that you are, absolutely, right.
I don't know much about currency matters, but isn't there a danger that this "quantitive easing" could not be used by individual countries, to the detriment of the whole?
Like foreign policy, financial policy could, also, be a matter that cannot be controlled by Brussels if a particular country decides to print cash. We all know how successful European foreign policy is!
