Quote from Martinghoul:
That's part of the problem... The size of the EFSF cannot be so large that it leads to the mkt pushing France into the "bad pack". So at the moment EFSF achieves its AAA rating by the good sovereigns "over-guaranteeing" the amount available to lend (in a couple of diffferent ways, but the latest is a 165% commitment). Problem, of course, is that with a EUR 2trln package, the mkt might not look too kindly on Germany and France underwriting a EUR 3.3trn off-balance sheet vehicle. However, this all can work in theory, since it's a matter of signaling strong commitment to the EMU, rather than the specific details. In the end it's a simple choice to either turn EMU into a fiscal union, with everything that entails, or for everyone to go their separate ways.
