Benchmarks Assurance

Establishing trust in Financial Benchmarks

Financial Benchmarks and Indices underpin transactions worth trillions of dollars across the financial services sector and beyond. Following the historical investigations into alleged manipulation of critical benchmarks – such as LIBOR and FX – the administration, contribution, and use of benchmarks and indices are now subject to significant regulatory requirements for global firms operating in the UK and Europe. Global reform of Inter Bank Offered Rates (“IBORs”) is also currently high on the agenda of regulators and firms alike.

Unsurprisingly, stakeholders ranging from financial regulators, executive management, those charged with governance, or external investors, have sought greater degrees of assurance. In particular, if all financial benchmarks are reliable and credible, regulations adhered to and the risk of manipulation reduced.

The need for such assurance has already seen considerable regulatory activity in recent years, with the increasing use of the IOSCO Principles for Financial Benchmarks and separately, Principles for Oil Price Reporting Agencies (collectively, “IOSCO”), along with continued regulatory scrutiny and oversight.

Both EU and UK Benchmark Regulation (EU and UK BMR) have led to a significant and sustained focus on benchmark assurance. Although regional in name, they have a global impact that continues to drive higher standards of regulatory oversight on the administration, contribution and use of financial benchmarks. In addition, with the reform of IBORs, such as LIBOR, well under way, the focus on financial benchmarks, and  assurances that market participants can have on their continued use, will continue to grow. 


The scope of global benchmark regulation covers requirements for companies who create and manage indices and financial benchmarks (administrators); companies who actively contribute data to benchmark administrators (contributors); and companies who use them in financial contracts (users). Understanding the scope of benchmark regulation and its application to a company is a critical first step in establishing confidence in ongoing compliance.

Governance and Control Assurance

Core to the compliance of benchmark regulation is reviewing and enhancing a company’s governance and control frameworks. Any review requires increased transparency and a focus on identifying and mitigating conflicts of interest – either actual or perceived. Any assurance on remedial work required to review, design, and introduce enhanced governance and oversight under a documented and embedded control framework, should not be underestimated.

Ongoing Assurance requirements

As well as impacting existing benchmark regulation and guidance, benchmark regulation includes various specific assurance requirements that companies could be affected by and must consider as part of their implementation plans. These include, but are not limited to:

EU BMR Requirements

  • Critical benchmarks now require annual external assurance (typically undertaken under ISAE 3000)
  • Certain commodity benchmarks now require annual external assurance
  • Interest rate benchmarks now require external assurance every two years starting after six months from the issue of the code of conduct
  • Third-country administrators under recognition need either external assurance or competent authority certification on their compliance of IOSCO principles (where required)
  • Administrators require reviews of contributors’ adherence to the code of conduct
  • Benchmark methodologies and input data require internal reviews.

IOSCO Principle Requirements

Critically, IOSCO requires the appointment of an independent internal or external auditor with appropriate experience and capability to periodically review and report on the Administrator’s adherence to its stated criteria and the requirements of the Principles.
