You're grasping at straws with your "follow the money".

Guilty as charged...

I'm still looking for a tangible villain. Given the mechanical inevitability of default for Greece (barring a deus-ex-machina from the ECB, which I think we can agree is not on the cards), the smart money is presumably gaming the ECB's stupidity for all it's worth.

The most obvious way of doing this is by buying CDS.

Therefore, anyone taking a major bet on Greek default, through a CDS position, may wish to influence outcomes by blocking off all alternatives to full payment (impossible) or default (jackpot).

Ratings agencies which declare "anything which is different from full payment (e.g. voluntary rollover) is equivalent to default" would seem to fit with such a strategy.

The head of a ratings agency who secretly held a massive CDS position might make a satisfying villain.

Just thinking out loud here.
