ACCBank is to quit the Irish market with the loss of about 180 jobs.
The Irish subsidiary of Dutch banking giant Rabobank said that next year it will close all its branches and business centres to the public and give up its banking licence.
It posted losses of more than 200 million euro for last year.
Kevin Knightly, the bank's country manager, said ACCBank has suffered significantly due to the deterioration of the Irish property market over the last five years.
"While costs have been cut significantly, including a substantial restructuring programme in 2009, we are heading towards a situation where, without intervention, our costs will exceed our income during 2014," he said.
"This is an unsustainable position and we need to take action now."
ACCBank said it will focus solely on debt recovery and all funds on deposit with the bank will be repaid in full to customers.
The closure will see 180 voluntary redundancies out of a workforce of 470.
ACCBank, an agri-lending bank, said it will continue to be a regulated entity and will support its customers in the farming sector. It is looking into outsourcing a small portion of its loan book that does not include its agri-business.
Rabobank said the closure would not impact its separate business in Ireland.
Mr Knightly added: "ACCBank has remained at the forefront of loan recovery activity in the Irish market. We will continue with our approach to loan recovery but do not need to be a fully licensed bank for this purpose."
