(44) Many financial instruments are priced by reference to benchmarks. The actual or attempted manipulation of benchmarks, including interbank offer rates, can have a serious impact on market confidence and may result in significant losses to investors or distort the real economy. Therefore, specific provisions in relation to benchmarks are required in order to preserve the integrity of the markets and ensure that competent authorities can enforce a clear prohibition of the manipulation of benchmarks. Those provisions should cover all published benchmarks including those accessible through the internet whether free of charge or not such as CDS benchmarks and indices of indices. It is necessary to complement the general prohibition of market manipulation by prohibiting the manipulation of the benchmark itself and the transmission of false or misleading information, provision of false or misleading inputs, or any other action that manipulates the calculation of a benchmark, where that calculation is broadly defined to include the receipt and evaluation of all data which relates to the calculation of that benchmark and include in particular trimmed data, and including the benchmark’s methodology, whether algorithmic or judgement-based in whole or in part. Those rules are in addition to Regulation (EU) No 1227/2011 which prohibits the deliberate provision of false information to undertakings which provide price assessments or market reports on wholesale energy products with the effect of misleading market participants acting on the basis of those price assessments or market reports.
