Spain Raises $5 Billion in Healthy Bond Sale Spain has raised an above-target €3.9 billion ($5 billion) in a successful debt auction that saw interest rates drop sharply despite renewed concern about whether the country needs international help. The Treasury said Tuesady that it sold €2.39 billion in in 12-month bills with a yield of 2.56 percent, down from 2.79 percent in the previous auction on Nov. 20. It sold €1.5 billion in 18-month bills at an average rate of 2.79 percent, down from 3.03 percent. The Treasury had set a maximum sale target of €3.5 billion, and demand was double the amount offered. Spain came under renewed pressure to seek help Monday as its secondary market borrowing costs - a measure of investor wariness - rose after Italian Premier Mario Monti's decision to resign caused market jitters.
