Moody's has cut Greece's credit rating again, citing a risk of default despite a recent debt write-off deal.
The rating agency cut Greece's rating from Ca to C, the lowest level on its scale.
Moody's acknowledged on Friday that the 107 billion euros ($US141.3 billion) deal was necessary to help stabilise Greece, but said the risk of a default remains high.
The BBC reports private investors are writing off much of the 206 billion euros they hold in Greek bonds, incurring losses of more than 70%.
Fitch also lowered its rating for Greek government debt on 22 February, from CCC to C.
