Permanent TSB insist failing the European Central Bank Stress Test will not impact on customers.
It was confirmed today to be the only Irish lender to fail the ECB's tests.
AIB, Bank of Ireland and Ulster Bank all cleared the stress tests on their loan books.
Permanent TSB was found to have a capital shortfall of 854 million euro.
The bank will probably look to raise the money from private investors rather than seek another taxpayer bailout.
Speaking on Savage Sunday Peter Brown from the Irish Institiute of Financial Trading said today's result is no surprise.
