According to the Irish authorities, how much will the four major banking groups need?

The Irish authorities say four major banking groups will need a further $ 34bn to make sure they survive any future financial shocks. The figure emerged from stress tests carried out on the troubled Irish banking sector following the financial crisis. The head of Ireland’s central bank, Patrick Honohan, acknowledged the scale of the operation.
    "The overall increase in capital required is sizable. The main underlying reason for such a large increase is the need to restore market confidence. It is a prerequisite to the banks returning to normal functioning that they should have ample capital to meet even the market’s gloomy prognostications."
