The high street bank has signed a 20-year lease agreement with Green Reit, an Irish real estate development trust, to let two-and-a-half floors covering 3,437 square metres in central Dublin. Barclays will pay €2.35m (£2.1m) in rent a year for the space.
The banking giant's licenced entity in Dublin, Barclays Bank Ireland, employs around 100 people. Barclays is also in talks with Irish regulators about extending its activities in Dublin, it revealed in July.
Last month, Bank of America (BofA) announced it has chosen Dublin as it post-Brexit base for its investment banking and markets operations.
BofA chief executive Brian Moynihan said Dublin is the “natural location to consolidate our legal entities as we transition”.
“We will move roles not only to Dublin but to other EU locations, with the focus on how we can best support our clients in these markets,” he added.
