Greece's bonds may fall more than 60% in value

BRUSSELS / Athens - European leaders pushed back a debt-crisis summit amid opposition to Germany's drive for deeper-than-planned Greek bond write-downs that Luxembourg's Prime Minister Jean-Claude Juncker says may exceed 60 percent.

When asked on television late Monday to comment on speculation investors may lose between 50 percent and 60 percent of the value of their holdings, Juncker said, "We're talking about even more." He didn't comment further.

The Oct 18 summit meeting was postponed to Oct 23 as Europe gropes toward a master plan for dealing with Greece's oversized debt, insulating the Spanish and Italian markets and shielding banks from the fallout.
