Rente op Griekse obligaties op eurozonerecord

The uncertainty caused by the deal has led Greek bonds to plummet in recent days, with yields on Greece’s benchmark 10-year bonds breaching 18.5 per cent on Thursday, a new euro-era high, wiping away all gains achieved after the bail-out deal was reached.

The issue has become highly politicised in Finland, particularly since Jutta Urpilainen, head of the Social Democrats, became finance minister after April’s national elections. Ms Urpilainen ran on an anti-bail-out platform, and only agreed to join the government of pro-European prime minister Jyrki Katainen if such collateral deals were part of future bail-outs.
