​The allegations and cases of benchmark manipulation across the globe have caused a number of governments and regulatory bodies to scrutinise how benchmarks are set and administered.

International: At the international level the International Organization of Securities Commissions (IOSCO) published Principles for Oil Price Reporting Agencies in December 2012 and its Final Report on Principles for Financial Benchmarks in July 2013, shortly after the Financial Stability Board established the Official Sector Steering Group of regulators and central banks to coordinate consistency of review of existing interest rate benchmarks. 

EU Benchmarks Regulation: At an EU level, on 1 January 2018, the EU Regulation on indices used as benchmarks in financial instruments and financial contracts or to measure the performance of investment funds (Regulation (EU) 2016/1011) entered into full application, subject to certain transitional arrangements. The stated overall objective of the EU Regulation is to help restore confidence in the integrity of benchmarks by enhancing the robustness and reliability of benchmarks, facilitating the prevention and detection of their manipulation and clarifying responsibility for and the supervision of benchmarks by the authorities. It regulates the administration of, contribution to and use of a broad range of indices and replaces corresponding benchmark regulatory regimes previously in place in member states. Amendments to the EU Benchmarks Regulation seek to address challenges with amending tough legacy contracts for IBOR transition purposes.

United Kingdom: The UK has onshored the Benchmarks Regulation and implemented certain of its requirements through secondary legislation and regulatory rules. The Financ​ial Services Act 2021 ​gives the Financial Conduct Authority (FCA) more powers to manage an orderly wind-down of critical benchmarks such as LIBOR. The Critical Benchmarks (References and Administrators' Liability) Act 2021 is intended to support the effective operation of the powers granted to the FCA under the Financial Services Act 2021.

National: Outside the EU, jurisdictions are taking different approaches to the regulation of benchmarks. Some jurisdictions like Australia, Singapore, Japan and Korea ​have adopted regulatory reforms that target a few, specifically designated benchmarks. Others, like the USA, have preferred to achieve the objectives of the IOSCO Principles through more robust enforcement rather than new supervisory architecture.
