Back in February, Tsangshan took an outsized short position on nickel with JP Morgan (and other banks), as well as a smaller position on the LME, totalling about $6 billion in notional value. Meanwhile, corporates like VW took long positions in nickel, relying on counterparties to pay out on these hedges.
When prices spiked after Russia’s invasion of Ukraine, Tsangshan was unable to pay margin calls, and nickel prices almost doubled. To protect its own brokers, and its clearing arm which serves as central counterparty for trades, the LME suspended trading and cancelled $4 billion of trades.
If Tsangshan had defaulted, JP Morgan might have faced a loss of $1 billion or more, but it managed to keep the loss to just $150 million. CEO Jamie Dimon added that the bank is now conducting a ‘post-mortem’ into the LME fiasco.
