There's a lot of moneyspeak here and it might be difficult to follow if you haven't familiarized yourself with Wall Street gibberish. Basically, the opposition leader in Greek parliament made a speech in which he accused the Prime Minister of acting as a foreign agent. He claims that the PM engaged in a profitable sale of Greek financial assets, namely an insurance policy (CDS) against Greek default. It is not clear for how much this/these CDS (if it/they exist, this is coming from the opposition after all) can be redeemed. Nevertheless, it is beyond odd that officials of the Greek government would (to use Kofinas' analogy) sell its only umbrella before a storm. It's analogous to a football game in which the home team is down by one point and has the ball on the other teams ten yard line with ten seconds to go, and then having the head coach sell the team's one remaining time out to the visiting team while the clock expires before he has a chance to kick a field goal, and the seller pocket at least part of the proceeds for himself. This is essentially what the opposition leader is alleging.
This accusation is lent considerable credibility by the shocking revelation that the Greek central bank extended the period for shorting Greek bonds (placing a bet that they would go into default) from three to ten days. For a nation facing imminent collapse, it is extraordinary beyond explanation that its central bank would facilitate adverse financial speculation. This is akin to a mother bear offering her cubs to a wolf pack.
And we must remember that the Greek central bank is a private bank, and part of a chain whose parent is the European Central Bank (ECB), which is part of the troika pushing Greece over the cliff.
Here's a video. Below it is a link to Kofinas' original article on the subject.
