i may have misunderstood what you said - i read it as: USD goes up because customers are fleeing european banks - or not? I said that when you change your preference for location of your accounts (legal) you do not change your base currency, e.g. USD.
if you meant something else then just forget it. cheers
p.s. i sold recently all remaining dollars at about 1.385 - i will go short when the dust settles. I am also long Yens for quite a few weeks.
