The bank has indicated it will use its existing European Union banks, in Dublin, Frankfurt and Luxembourg to anchor its European Union operations after Brexit.

“This new building gives us room to grow and some flexibility within the European Union,” senior country officer for JP Morgan in Ireland Carin Bryans said in the statement.

Ireland has engaged on a major lobbying campaign during the past year to try to convince companies with large bases in the United Kingdom to consider moving some of their staff to Ireland to maintain access to the European Union’s single market.

Hubertus Vaeth, the head of Frankfurt’s campaign to promote the city to banks since Britain voted to leave the EU, told Reuters earlier this month he expected the five largest U.S. investment banks to move staff to more than one EU location with around 1,000 going to Frankfurt and possibly more to Dublin.

Rivalry between the different EU cities has become acrimonious at times, with Ireland complaining to the European Commission that it is being undercut by predatory behaviour by other centres.

Ireland’s financial services minister, Eoghan Murphy, said in a statement on Monday that JPMorgan’s announcement was “a welcome vote of confidence in the strength of Ireland’s offering and Dublin’s status as a major financial centre.”
