When Matthew Chamberlain awakened at 5.30am on March 8 2022 and glanced at metals costs on his cellphone, he instantly knew one thing was fallacious.
Because the chief govt of the London Metallic Alternate scrolled by means of his cell — nonetheless bleary after coping with emails till almost 11pm the night time earlier than — he grew to become “alarmed” on the pace at which the value of nickel was rising.
By 5.53am the nickel value had jumped 30 per cent — and was nonetheless going up. “I had by no means witnessed such excessive value actions,” Chamberlain says in courtroom paperwork. “There was little doubt in my thoughts that the market had develop into disorderly.” Simply after 6am nickel costs had soared previous $100,000 per tonne, up from $60,000 when he awoke.
Chamberlain checked his inbox, seemed on the information, and did a tough calculation of the intraday margin name his customers can be required to pay to maintain open their trades at such an elevated value: greater than $10bn, he estimated.
The precise quantity turned out to be almost double that — sufficient to push a number of LME members to the brink of default and pose a “systemic danger” to the market, in response to Chamberlain’s testimony.
What Chamberlain knew, and when — and the way his thought course of developed throughout that fateful day — are on the centre of a high-stakes authorized battle that may decide the way forward for the LME and has the facility to reshape London’s monetary markets.
Within the case, hedge fund Elliott Associates and market maker Jane Avenue World accuse the LME of making hasty and unlawful decisions in the course of the nickel market disaster of March 8, 2022. They’re looking for compensation of almost half a billion {dollars}.
Later that day Chamberlain suspended trading in the nickel market, and cancelled all nickel trades that had taken place earlier that morning. Elliott says it was disadvantaged of $728mn of gross proceeds due to the cancellation.
This text relies totally on courtroom paperwork submitted forward of the trial, together with skeleton arguments and witness statements.
With the case underneath approach in London this week, the face-off between the hedge funds and the 146-year-old commodity alternate has gripped the Metropolis. Its ramifications might ripple far past the LME itself.
“Everyone seems to be watching it fastidiously,” says Jonathan Herbst, head of economic providers at regulation agency Norton Rose Fulbright. “If it had been to succeed, there can be implications for the entire market,” together with different exchanges, he provides.
At stake will not be solely the way forward for the LME, which can also be being investigated by regulators over its dealing with of the nickel disaster, but in addition the function of London itself as a monetary centre.
In authorized phrases, the case is uncommon as a result of it’s a judicial assessment — a kind of case sometimes introduced in opposition to authorities departments and public authorities, to problem whether or not their decision-making has been lawful.
In bringing this judicial assessment in opposition to an alternate, the case might set up precedents that apply to different exchanges as nicely, significantly how an alternate’s leaders make choices in time of disaster.
Inside a crowded and stuffy courtroom on the Royal Courts of Justice in London, the listening to this week has revealed recent particulars about how the LME’s chief govt dealt with the disaster, and why he determined to retroactively cancel $12bn of nickel trades on March 8.

The size of the disaster was already turning into obvious on March 7 when rising nickel costs and file intraday margin calls meant that some LME members had been struggling to pay.
The LME took the “extraordinarily uncommon” step of deciding to pause intraday margin calls that afternoon, in response to witness statements from Adrian Farnham, chief govt of LME Clear, the clearing home.
“In observe, this meant that we didn’t make roughly $2.5bn of intraday margin calls that might in any other case have been made throughout March 7 — as an alternative, these quantities had been referred to as in a single day,” says Farnham’s witness assertion.
A key query raised by the claimants is why the LME concluded that the market was “orderly” on the night of March 7 — regardless of purple flags and surging costs throughout buying and selling — but determined it was “disorderly” on March 8 when the volatility continued. That day, surging costs compelled the LME to make an unprecedented 9 intraday requires extra margin, totalling $7bn.
In courtroom on Wednesday, the LME’s barrister Jonathan Crow mentioned that there have been “important variations” between situations on the 2 days, including that the value swings on March 8 had been “incomparable” to the day earlier than.
On the morning of March 8, after waking as much as the rocketing nickel value, Chamberlain began getting calls from LME members who mentioned they may not have the ability to meet their margin calls — which might put them in technical default on their funds to the LME.
The LME had by no means been in a scenario the place multiple member defaulted on the similar time, a risk that appeared very actual on the morning of March 8. Not solely would this have threatened stability throughout different commodities markets, but it surely additionally had the potential to threaten the LME itself, as a result of when a member defaults, the LME has to step in to cowl these trades.
Earlier authorized filings present that the LME’s personal clearing home default fund was in severe danger after the sudden market strikes.
Chamberlain says he cancelled the trades to stop the “systemic danger of a number of simultaneous defaulting members”, and that he and his colleagues thought of different choices — together with doing nothing; and adjusting the trades to a lower cost — however discovered these unsuitable. On the day prior to this, the alternate had additionally thought of imposing a every day value restrict on nickel, however determined this was impractical to do at quick discover, and tabled it for longer-term consideration.
Nonetheless, his witness statements additionally reveal stunning gaps. Chamberlain says he was unaware that the market turmoil was influenced by a large short position held by Tsingshan, the Chinese language nickel producer, in over-the-counter (OTC) contracts which aren’t seen to the LME.
The place was frequent data available in the market and famous in media studies on March 8, however Chamberlain says he solely grew to become conscious of it later.
Chamberlain additionally didn’t realise that his colleagues in Asia had eliminated in a single day the value bands that usually forestall giant swings, which can have contributed to the fast rise in costs.
The function of the LME’s proprietor — the Hong Kong Alternate, which bought the LME in 2012 — can also be underneath a highlight on this trial. Chamberlain says he was in touch with the HKEX chief govt in the course of the disaster, and that colleagues from HKEX joined a number of calls on March 8 however didn’t search to offer recommendation or affect any choices taken by the LME, in response to witness statements.
Within the authorized case, Elliott says the LME had higher choices than cancelling the trades — equivalent to doing nothing, or honouring the trades however decreasing the margin name — and unfairly favoured sure market individuals over others when it cancelled the trades.
“It’s actually no exaggeration to say that this determination despatched shockwaves by means of commodity markets,” mentioned Monica Carrs-Frisk, one of many legal professionals representing Elliott, in opening statements in courtroom on Tuesday.
Tom Houlbrook, an Elliott commodities portfolio supervisor, in written testimony submitted to the courtroom calls the retrospective cancellation of nickel trades by the LME “completely unwarranted”.
“I imagine they’ve exceeded their lawful powers [by cancelling the trades], and have each disadvantaged the claimants of their authentic revenue on their trades, and materially undermined the integrity and stability of the market which the defendants are answerable for managing,” he says.
Nonetheless Crow mentioned that the alternate had an obligation to “intervene in moments of dysfunction.”
“The LME will not be meant to be a spectator,” Crow advised the courtroom. “It’s meant to be working an orderly market.”
