The G20/OECD Principles of Corporate Governance are the leading international standard for corporate governance. Following their adoption by the OECD Council at Ministerial Level in June 2023 and their endorsement by G20 Leaders in September 2023, the OECD Corporate Governance Committee (Committee) has turned its attention to supporting the Principles’ implementation. As one of the Key Standards for Sound Financial Systems adopted by the Financial Stability Board (FSB), the Principles are globally recognised as an important benchmark supporting the improvement of legal, regulatory and institutional frameworks for corporate governance with a view to promoting market confidence and integrity, economic efficiency, sustainable growth, and financial stability across jurisdictions globally.
By providing an updated tool to evaluate and encourage jurisdictions’ implementation of the Principles, the Committee is therefore pleased to issue this Methodology for Assessing the Implementation of the G20/OECD Principles of Corporate Governance (Methodology). Together, the Principles and Methodology form the basis for voluntary self-assessments by jurisdictions, as well as for OECD corporate governance assessments, including for jurisdictions seeking accession to the OECD. This revised Methodology has also benefited from the input of the World Bank and International Monetary Fund, with a view towards their use for corporate governance assessments under the auspices of their Review of Observance of Standards and Codes (ROSC) and Financial Sector Assessment Programme (FSAP). The Methodology may also be used to support more targeted reviews on selected corporate governance priorities. The 2025 revision of the Methodology takes account of all recent changes to the Principles and includes significant updates to its structure and content to facilitate more effective assessments.
This latest update to the Methodology was prepared by the Corporate Governance Unit of the Capital Markets and Financial Institutions Division within the OECD Directorate for Financial and Enterprise Affairs. The team included Valentina Cociancich, Thomas Dannequin, Caio De Oliveira, Fianna Jurdant, Tiziana Londero, Alejandra Medina, and Akiko Shintani with additional contributions from Sebastian Abudoj, Takashi Sudo, and Yunus Emre Yildirim, under the supervision of Serdar Çelik, Head of Division, and Daniel Blume, Head of the Corporate Governance Unit. The publishing and communication process was supported by Greta Gabbarini and Liv Gudmundson, who provided editorial guidance and expertise in communications.
