Key Takeaways
  • • Elliott Investment Management has filed a new lawsuit against the London Metal Exchange and parent company HKEX, alleging breaches of UK competition law related to the cancellation of approximately $12 billion in nickel trades during the March 2022 market event.
  • • This represents Elliott's second legal action against the LME over the nickel trades dispute; the hedge fund's earlier claim seeking $456 million damages failed through the UK courts.
  • • The March 2022 nickel market experienced a dramatic short squeeze that resulted in unprecedented trading volatility and forced the LME to halt trading and cancel contracts, triggering significant losses across the market.
  • • The new competition law allegation suggests Elliott is pursuing a different legal strategy after its initial damages claim was unsuccessful, focusing on regulatory and antitrust grounds rather than contract-based arguments.
Summary
Elliott Investment Management has escalated its dispute with the London Metal Exchange by filing a fresh lawsuit alleging breaches of UK competition law in connection with the LME's cancellation of approximately $12 billion in nickel trades during the volatile March 2022 market event. The action targets both the LME and its parent company, Hong Kong Exchanges and Clearing (HKEX).

This lawsuit represents Elliott's second attempt to pursue legal remedies following the March 2022 nickel market disruption. The hedge fund's initial claim, which sought $456 million in damages, was previously dismissed through UK courts. The shift to a competition law framework indicates a strategic recalibration, with Elliott now challenging the LME's conduct on antitrust and regulatory grounds rather than relying solely on contractual breach arguments.

The March 2022 nickel market event was characterized by an extreme short squeeze that destabilized global nickel trading. The LME's decision to halt trading and cancel executed contracts was intended to stabilize the market but resulted in substantial losses for numerous market participants. Elliott's allegation that these actions constituted competition law violations suggests the hedge fund believes the exchange's handling of the crisis may have disadvantaged certain market participants or violated fair competition principles under UK law.

The outcome of this competition-focused litigation could have broader implications for exchange regulatory authority and market crisis management protocols, particularly regarding the circumstances under which exchanges may cancel trades and the legal standards governing such decisions.
