Quote from Daal:
The debt to GDP might been kinda high but by looking at the spreads over bunds and CDS it seems clear everyone thought the party was going to last forever. By selling by the weak members I mean that people will have to sell their â¬s that they have in hand and in EU banks for the new currency, this should exert downward pressure on the fx rate(though their money on the national banks might be converted automatically), there will be also a decline in the need for â¬s since the country will no longer do business/trade/turism in that currency(If you take out NY, I'm pretty sure there will be less demand for USDs, etc)
As for the fair value to DEMUSD I'm not sure but I also know how markets think, if one guy goes out everyone will that think there will be a domino effect and they will extrapolate the effects I mentioned above, which might lead to panic selling of EURUSD. So I'm not sure the fair value will be reached anytime soon
