Cote If that were the case, France & Germany would just give the aid money to their banks, without passing through Greece at all.
Firstly, it's illegal under EU law. Secondly, every nation already has bail-in legislation in statute to fund collapsing banks (UK passed it into law in 2012), and thirdly, a colapse of any bank would trigger astronomical derivative and credit default swap obligations that could never be met by any financial instiution on the planet.
The only viable way out of a systemic bank failure this time around is to remove as much wealth from a nation's citizens as possible, and write off the debt without legally calling it a 'default',thus preventing the triggering of derivitives obligations.
The only way out of a catastrophic failure continent wide, is to wipe the slate clean, call a debt jubilee, reset the currency, and start over. A nice world war would be a good distraction to blame this on, if we can ever manage to get the thing started.
We do not read history, and so we repeat it.
