In a response to a recent Department of Finance consultation exercise, Nationwide UK Ireland stated that the methodology for calculating the banking levy was undermining the viability of their Irish operations:- http://www.finance.gov.ie/sites/default/files/Nationwide UK for publication.pdf NUK Ireland subsequently decided to close their Irish operations. RaboDirect expressed similar concerns. According to their response, they are shouldering 3% of the overall cost of the bank levy, with only a 1% market share:- http://www.finance.gov.ie/sites/default/files/Rabobank for publication.pdf Is there a danger that Rabo will follow NUK's lead and exit the Irish market? There has certainly been some recent speculation on Rabo's future plans:- https://www.askaboutmoney.com/threads/is-rabobank-preparing-to-leave-ireland.202672/ Bear in mind that these banks do not participate in the Irish deposit guarantee scheme and impose no contingent liability on the Irish taxpayer. Is the Government deliberately trying to restrict competition in the deposit market in order to artificially boost the net interest margin of the domestic banks in which holds a stake? TBH, I'm surprised this hasn't been picked up by any financial journalists - this is all publicly available information.
