Greek bank deposits have fallen to their lowest in more than a decade, new statistics show, as Greeks worried about their new government's painfully slow negotiations with creditors withdraw savings.

Figures from the European Central Bank published Friday showed more than 5 billion euros ($5.5 billion) were withdrawn in April.

That leaves household deposits at the end of the month at 139.4 billion euros ($151.9 billion), down from 145 billion euros in March. The figure is the lowest since November 2004, when deposits stood at 137.2 billion euros.

Athens has insisted in recent days it is close to a deal, indicating an agreement could come as soon as this weekend that would unlock desperately needed funds from its international bailout. But European officials have said much remains to be done.
