London | The European Central Bank has said it does not know when it will be able to cut interest rates again, after announcing it would leave its benchmark rate on hold at 3.75 per cent for this month.

The central bank for the 20-country eurozone said late on Thursday (Friday AEST) that it would have to wait and see how the economic numbers panned out over the northern summer before deciding whether to build on its initial quarter-point rate cut in June.
