Another glaring example of how broken the Greek funding market is, is the record negative basis spread in Greek 5 Year Cash-CDS, which as of today is almost -200 bps (see below). As a reminder, the basis trade's massive inversion in the days after the Lehman collapse is among the primary reasons for the implosion of Merrill, and the spectacular blow up of Deutsche's prop trading desk. What the primary implication of this observation is that the market is essentially saying that the imminent Greek bankruptcy will likely be in the form of a voluntary restructuring, which will not trigger CDS, although that is not the full story. The risk/return scenario, as Credit Trader points out, is assuming a 200bps upside to bond spreads, or a 400 bps downside to an inline level with the rest of Europe, in essence a 33% chance of a free fall bankruptcy, whose implication would most likely be the collapse of the Eurozone, as the EMU would be defunct if a member country escalates into an uncontrollable bankruptcy.
