It's part of their expansion in the capital in the wake of Brexit.
The company has signed a 20 year lease and will pay €2.35 million a year in rent for the city centre building. The block on Molesworth Street contains two and a half floors of office space, covering a total of 3,437 square metres.
The redevelopment of the building is set to be completed within the last three months of the year, but it's not yet known when exactly the banking giant will take possession of the space.
Last month Barclays announced it was expanding in Dublin ahead of Britain's departure from the EU. It's thought the office building can accommodate about 400 employees.
JP Morgan and Bank of America are some of the other financial institutions planning to expand in the city post-Brexit.
