Charles Dallara, theManaging Director of the IIF, the body which is negotiating on behalf of private sector investors (PSI) in the Greek bond swap, indicated yesterday that private bondholders have made their best offer and that it is now up to the International Monetary Fund (IMF) and the European Union to decide whether the deal is acceptable and whether it will be enough to stave off a default or not. Reports last week suggested that private bondholders were willing to take a haircut of between 65% to 70% as part of a "voluntary" debt swap plan and that the coupon on the new bonds issued would be somewhere between 3% and 4%.
