The Financial Regulator (Irish: Rialtóir Airgeadais), officially the Irish Financial Services Regulatory Authority, was the single regulator of all financial institutions in Ireland from May 2003 until October 2010 and was a "constituent part" of the Central Bank of Ireland. It was re-unified with the Central Bank of Ireland on 1 October 2010 and its board structure was replaced by a new Central Bank of Ireland Commission.
