The London Metals Exchange has closed trading in nickel contracts until future notice, and will be cancelling trades from March 8th, 2022, following an unprecedented short squeeze that took the price of nickel from $25,400/tonne to $29,750/tonne in three trading days, then to $42,995/tonne on Monday, before intraday trading on Tuesday took the price beyond $100,000/tonne on trades that will now be cancelled.
