Greek 10Y spreads breach 1% as global bond selloff hits periphery

Greek government bond spreads over German bunds have widened past 100 basis points, reflecting contagion from a global bond market rout. The move signals renewed investor concern over peripheral eurozone debt sustainability, though the trigger appears external rather than Greece-specific. The development matters as it tests ECB backstop credibility and could force policy response if spreads continue to widen.
