Thursday, in theory, is the deadline for Greece's bond swap (where private sector investors will take a 75% haircut).
Despite the hype being spewed forth by Greek authorities, and those with a vested interest in seeing the deal go through (ie the institutional investors), Greece has been forced to deny rumours that Thursday's deadline may be moved back. Unsurprisingly no one actually believes that the deal can take place without CACs (collective action clauses) being triggered.
The hedge funds have most to gain from CACs being triggered and Greece being declared in default. Hence, hype about IIF's accepting the deal is irrelevant.
The silence of the hedge funds, and the denials about a postponement of Thursday's deadline speaks volumes.
