Greek 10-year bonds were under pressure on Thursday, with the yield climbing to 4.5 percent, a day after a mass sell-off of bank shares at the Athens Stock Exchange (ASE).
Surging rates for US bonds, now at seven-year highs, have also affected Greek bonds.
Conversely, the banking index at the ASE, just after 2 p.m. (12.00 GMT) on Thursday was rallying to the tune of 5.78 percent.
