Italian and Spanish bonds jumped as borrowing costs slid at auctions and the European Central Bank kept its benchmark interest rate unchanged. German debt slipped.
The advance pushed Spanish two-year note yields to the lowest since March. The government sold 10 billion euros ($12.7 billion) of notes, twice the sales target, while Italy auctioned 12 billion euros of bills, easing concern the countries would struggle to finance their debts. The ECB held its main rate at 1 percent, an outcome predicted by economists in a Bloomberg survey. German 10-year bunds pared declines as reports showed U.S. retail sales and jobless claims missed estimates.
