LME SPECIAL COMMITTEEA day earlier, on March 7, when LME benchmark nickel prices had soared 66% to nearly $50,000 a tonne, the LME's Special Committee had met, Jane Street's document said.
The Committee, which has emergency powers, "concluded that the nickel market remained orderly, since there were geopolitical and macroeconomic reasons for the price increases".
The next day, however, when nickel prices skyrocketed, the committee did not meet, the document said.
Jane Street executed nickel trades from 1:37 a.m. on March 8 and was due total proceeds on those trades of $32.7 million, it said in the document.
The LME is also facing fresh lawsuits from ten hedge funds and asset managers for cancelling nickel trades.
