Banks in Spain and Italy are curbing loans and charging customers more as aftershocks from the sovereign debt crisis drive their own borrowing cost higher.

"They can't lend what they don't have, I suppose," said Francesc Elias, the owner of Bomba Elias, a pumps and filters maker near Barcelona, which shelved a 100,000-euro ($144,000) plan to open a Bahrain office when it couldn't get an affordable bank loan. "The banks are very clever about finding new ways to charge us more."

Spanish and Italian government bond yields surged to euro- era records this quarter as Greece struggled to avoid default, driving the cost of insuring against nonpayment by the region's banks to a record and making it harder for them to sell bonds. Spain pays 5.35 percent for 10-year money, up from an average of 4.07 percent in the first half of 2010, while Italy pays 5.65 percent compared with a 4.05 percent average last year.
