Quote from Martinghoul:
Italy is the no. 2 sovereign issuer in the world, after the US, in terms of the amount of debt outstandind (arnd $1.4trn). If Italy goes, I'd suggest the choice of which bank to entrust your money to would be the least of your worries.
That doesn't sound too confidence-inspiring. Beeing vaguely familiar with italian culture, i'm figuring, if Greece hid X in off-balance sheet transactions, Italy hides probably X^X.
