According to media reports, the borrowing cost on the newly issued bonds by Greece to private sector bondholders, after the debt-swap deal reached on Friday, rose to 19% and 14% for the 11- and 30-year notes respectively.

In fact, the rise reflects the worries in markets regarding Greece's ability to repay debt amid some concerns after using collective action clauses (CACs) in the deal with private creditor, which was deemed as a technical default by the International Association of Swaps and Derivatives (ISDA).
