EU Said to Consider 50% Greek Writedown

European officials are considering writedowns of as much as 50 percent on Greek bonds, a backstop for banks and continued central bank bond purchases as key planks in a revamped strategy to combat the debt crisis, people familiar with the discussions said.

The Greek bond losses may be accompanied by a pledge to rule out debt restructurings in other countries that received bailouts, such as Portugal, to persuade investors that Europe has mastered the crisis, said the people, who declined to be identified because the negotiations will run for another week.
