Each broker on this page is authorised by the Central Bank of Ireland (CBI), a Tier 1 regulator responsible for financial services oversight in Ireland and part of the European Union framework. CBI-regulated brokers are required to set a maximum leverage cap for retail traders at 1:30 and must comply with strict rules on client fund segregation. Irish authorisation typically enables EU passporting, allowing brokers to serve clients across the European Economic Area.
