Lower-rated euro zone bond prices slipped on Friday, deepening sharp falls on Thursday triggered by nervousness about the stability of the Greek government, a tax on foreign holders of Greek bonds, and weak growth.

The rally in peripheral government bonds had been fairly steady since the start of the year, but some analysts suggested the reversal might be more than a blip.
