Italy was forced to pay its highest interest rate since the euro’s creation to sell five-year bonds—a sign of skepticism that new governments in Italy and Greece will be able to simultaneously boost economic growth and reduce high public-debt levels……Industrial production in the euro zone plunged 2% in September from August, the steepest slide since February 2009, according to the European Union’s statistics agency. The decline stretched from the weak periphery of Spain, Italy and Portugal to powerhouses such as Germany, France and the Netherlands. Compared with a year ago, output rose just 2.2%—the weakest gain in nearly two years. The data suggest “the euro-zone will soon fall back into another fairly deep recession,” said Ben May, economist at consultancy Capital Economics.
