PTSB 'most vulnerable'

Permanent TSB will have to find €170m for every percentage point it falls short of European capital standards after Sunday's ECB stress test results, if it fails the review.

"Permanent TSB is the most vulnerable of the Irish banks," according to Emmet Gaffney from Investec.

But Mr Gaffney said there is little risk of taxpayers being hit for fresh cash to cover any shortfall, because the bank already has a €400m cushion from taxpayers.

AIB and Bank of Ireland are regarded as better capitalised, Mr Gaffney added.
