The claim runs back to March 2022, when the LME suspended nickel trading and cancelled roughly $12 billion of trades in a single session after prices doubled in hours on a short squeeze tied to Tsingshan Holding Group's position. Elliott, which held nickel contracts caught in that cancellation, has pursued the LME (majority owned by HKEX since the 2012 acquisition) through the UK courts since 2022 and lost at both the High Court and Court of Appeal. The nickel trading legal claim reported this week names HKEX alongside the LME, extending a dispute that has already run more than four years without a payout to Elliott.

Look, the mechanics matter here more than the headline. HKEX bought the LME for £1.4 billion in 2012 specifically for its role as the world's base-metals price-setter (the kind of infrastructure asset that is supposed to generate steady clearing fees, not courtroom bills). A claim that reaches past the exchange itself and into its parent tests whether an owner can be held to account for a subsidiary's market-intervention decisions, which is a different and larger question than whether the 2022 cancellations were lawful. HKEX has not disclosed a provision for this litigation in its filings, and until it does, the exposure is a legal question, not a balance-sheet one.
