The Regulations designate the Central Bank of Ireland as competent authority to implement Directive 2013/36/EU and the Capital Requirements Regulation. They set out authorisation and market access rules for credit institutions and investment firms, mutual recognition for branches and services, and a detailed regime governing qualifying holdings (prior notification, assessment and possible opposition). Minimum initial capital, grandfathering and notification duties for firms are prescribed.

The instrument establishes prudential supervision standards: governance, internal capital adequacy, risk management, recovery and resolution planning, liquidity and leverage controls, and remuneration oversight. It provides for consolidated supervision and colleges of supervisors, prescribes capital buffers (conservation, countercyclical, O‑SII/G‑SII), enforcement powers and administrative penalties, disclosure duties and transitional arrangements, and amends/revokes related domestic law.
