Benchmark regulation

The London Metal Exchange is authorised and regulated by the Financial Conduct Authority in respect of its benchmark administration activities under the European Benchmarks Regulation (Regulation No (EU) 2016/1011) as “onshored” into UK law and amended by The Benchmarks (Amendment and Transitional Provision)(EU Exit) Regulations 2019 (UK BMR). The London Metal Exchange is also a recognised investment exchange under Part XVIII of the Financial Services and Markets Act 2000 (FSMA) and a regulated market pursuant to the Markets in Financial Instruments Directive. The LME is an exempt person for the purposes of FSMA in respect of its exchange activities.

LME’s UK BMR Statement of Compliance

The LME, in its capacity as a benchmark administrator and in accordance with Article 29 of the UK BMR is listed on the FCA Benchmark Register, permitting use of the LME's Benchmarks in the United Kingdom.

As a third-country benchmark administrator, the LME is utilising the transitional arrangements under Article 51(2) of the European Benchmarks Regulation as amended and extended from time to time in order to continue providing its benchmarks for use by supervised entities in the European Union.

LME’s UK BMR Statement of Compliance

LME benchmarks

A full list of the LME’s prices, including information on which of these prices are benchmarks under the UK BMR, is included in the LME List of Benchmarks (PDF). Links to the benchmark statement and benchmark methodology for each LME Benchmark Family can also be found in this document. Benchmark statements and methodologies should be read in conjunction with the Benchmark Administration - Definitions (PDF).

The LME’s benchmarks are categorised as non-critical commodity benchmarks that are subject to Annex II of the UK BMR.

The LME’s view is that market participants who trade on the LME’s execution venues are not “contributors” of input data within the meaning of the UK BMR and consequently, are not subject to a code of conduct. However, supervised entities are reminded that their usage of an LME benchmark may trigger other obligations under the UK BMR.

LME prices not identified as a benchmark under the UK BMR may not be used as benchmarks.

All use of LME prices is subject to applicable licensing requirements. Further information is available on the Market Data Licensing page.

Update in relation to Official Prices and Closing Prices

Links to the benchmark methodologies for the Official Prices and Closing Prices are set out in the LME List of Benchmarks referred to above.

The LME enacted its BC pandemic plan on Monday 23 March 2020 in response to the outbreak of COVID-19, and the Ring was shut for a period of time. In light of feedback from the Discussion Paper on Market Structure issued in January 2021, the LME took the decision that the Closing Prices should move permanently to electronic determination and that the transition to electronic pricing would take place on the basis of the LME’s BCP Policy. Following consultation (in LME Notice 21/112) and in light of feedback received, the LME also took the decision to return Official Prices to the Ring on its re-opening on 6 September 2021 following the temporary Covid-19 related suspension.

In order to give effect to the decisions set out above, the LME issued Notice 21/158 setting out the updates that were made to pricing-related documents.

As set out on the LME’s COVID-19 preparedness webpage, the LME has robust business continuity procedures in place designed to deal with a wide variety of potential developments to ensure service resiliency, availability and stability across our platforms, during and around unforeseen events, crisis, or out-of-the-ordinary operating environments.
