Samuelson on European Debt

Just last week, European leaders were putting the finishing touches on a plan to enlarge a bailout fund from an effective size of roughly 250 billion euros (about $350 billion) to 440 billion euros ($615 billion) and eventually to 500 billion euros ($700 billion). By lending to stricken debtor nations, the fund would aim to prevent them from defaulting on their government bonds, which could have ruinous repercussions. Banks could suffer huge losses in their bond portfolios; investors could panic and dump all European bonds; Europe and the world could relapse into recession. 
Unfortunately, the odds of success are no better than 50-50.
Europe must do something. Greece and Ireland are already in receivership. Private investors won't buy their bonds at reasonable rates. There are worries about Portugal and Spain; Moody's recently downgraded both, though Spain's rating is still high. The trouble is that the sponsors of the bailout fund are themselves big debtors. In 2010, Italy's debt burden (the ratio of its government debt to its economy, or gross domestic product) was 131 percent; that exceeded Spain's debt ratio of 72 percent. Debt ratios were high even for France (92 percent) and Germany (80 percent).
