Italian 10-year bond yields have fallen sharply this week but remain within striking distance of the 7% rate that has pushed other euro-zone governments over the edge. They pared early gains on Friday to trade seven basis points lower at 6.596%, off session lows of 6.48%.
Talks remained delicately poised on Greece's debt swap deal, seen as vital to efforts to stave off a disorderly default of the euro-zone's weakest link.
