In July 2013, the International Organisation of Securities Commissions (IOSCO) published the Principles for Financial Benchmarks, setting standards for organisations administering financial benchmarks. They are intended to promote the reliability of benchmark determination and address governance, quality and accountability mechanisms.

The BBSW Assessment vs the IOSCO Principles for Financial Benchmarks – June 2026 is available here, has been created to provide market participants, regulators and other interested stakeholders with a comprehensive and transparent assessment of BBSW against the IOSCO Principles for Financial Benchmarks.

This assessment sets out how the Administrator meets each of the IOSCO Principles in the design, governance, determination, publication and oversight of BBSW. It reflects the current BBSW methodology, conventions and control framework, including enhancements implemented since the prior IOSCO compliance assessment completed in 2022.
