In March 2023, the London Metal Exchange and LME Clear published a two-year action plan to enhance and strengthen their markets.

The action plan addresses recommendations put forward in the Oliver Wyman report, following events in the nickel market in 2022, and aims to:

  • Embed the findings of independent, internal, and regulatory-led reviews to manage risk through enhanced controls.
  • Enable the market to provide deep and resilient liquidity for LME participants and members.
  • Build confidence in the reliable and transparent operation and governance of the LME Group’s markets.
  • Evolve market structure, demonstrating the Group’s ability to deliver modernisation and change.
