On August 12, 2016, a Commission Implementing Regulation establishing a list of critical benchmarks used in financial markets under the Benchmark Regulation was published in the Official Journal of the European Union. The Benchmark Regulation provides for different categories of benchmarks depending on the risks involved, imposing additional requirements on benchmarks considered to be critical, including the power of national regulators to mandate, under certain conditions, contributions to or the administration of a critical benchmark. The Commission Implementing Regulation stipulates that the Euro Interbank Offered Rate is a critical benchmark on the basis that it is important for credit loans and mortgages in the EU. EURIBOR is the first benchmark to be listed. The Commission Implementing Regulation entered into force on August 13, 2016. 

For the most part, the Benchmark Regulation will apply from January 1, 2018. Certain provisions, giving powers to ESMA to prepare draft technical standards and to the Commission to adopt delegated legislation, applied from June 30, 2016.
