The Investment Intermediaries Act 1995 marks a pivotal development in the regulation of Ireland's financial services sector. This comprehensive legislation was enacted to address previous regulatory fragmentation, establishing a robust framework for the licensing, supervision, and conduct of investment intermediaries. Key to the Act is the requirement for firms to be authorised by the Central Bank of Ireland, which ensures that only those meeting specific standards of fitness and financial soundness can provide investment services. This rigorous authorisation process is complemented by clear conduct-of-business rules designed to enhance consumer protection, requiring intermediaries to act transparently and in their clients' best interests.

Further, the Act places a strong emphasis on the safeguarding of client assets, mandating strict protocols for the handling of client funds to mitigate the risk of misuse. The Central Bank holds extensive supervisory powers, enabling it to enforce compliance through inspections and penalties for violations. Additionally, the Act aligns with European Union directives, thereby bolstering Ireland's reputation in the international financial arena and supporting the establishment of the International Financial Services Centre (IFSC).
