2012 JPMorgan Chase trading loss
In April and May 2012, large trading losses occurred at JPMorgan's Chief Investment Office, based on transactions booked through its London branch. The unit was run by Chief Investment Officer Ina Drew, who has since stepped down. A series of derivative transactions involving credit default swaps (CDS) were entered, reportedly as part of the bank's "hedging" strategy. Trader Bruno Iksil, nicknamed the ''London Whale'', accumulated outsized CDS positions in the market. An estimated trading loss of US$2 billion was announced, with the actual loss expected to be substantially larger. These events gave rise to a number of investigations to examine the firm's risk management systems and internal controls.
==Background==
In February 2012, hedge fund insiders such as Boaz Weinstein of Saba Capital Management became aware that the market in credit default swaps was possibly being affected by aggressive trading activities. The source of the unusual activity turned out to be Bruno Iksil, a trader for JPMorgan Chase & Co. Market-moving trades by the bank's Chief Investment Office had first been uncovered in June 2011 by trade journal Creditflux, which reported on anomalies in CDX HY index tranche pricing dynamics caused by Iksil's trading activity. The same journal reported on further tranche trading activity by the JP Morgan unit two months later. By 2012, heavy opposing bets to his positions had been made by traders, including another branch of JPMorgan, who purchased the derivatives that JPMorgan was selling in such high volume. Early reports were denied and played down by the firm in an attempt to minimize exposure. Major losses of $2 billion were reported by the firm in May 2012 in relation to these trades. On July 13, 2012, the total loss was updated to $5.8 billion with the addition of a $4.4 billion loss in the second quarter and subsequent recalculation of a loss of $1.4 billion for the first quarter. A spokesman for the firm claimed that projected total losses could be more than $7 billion. The disclosure, which resulted in headlines in the media, did not disclose the exact nature of the trading involved, which remained in progress as of May 16, 2012 as JPMorgan's losses mounted and other traders sought to profit or avoid losses resulting from JPMorgan's positions. As of June 28, 2012, JPMorgan's positions were continuing to produce losses which could total as much as $9 billion under worst-case scenarios. The trades were possibly related to CDX IG 9, a credit default swap index based on the default risk of major U.S. corporations that has been described as a "derivative of a derivative". On the company's emergency conference call, JPMorgan Chase CEO Jamie Dimon said the strategy was "flawed, complex, poorly reviewed, poorly executed, and poorly monitored".〔("Two Billion Dollar Hedge" ) ''Financial Times''.〕 The episode is being investigated by the Federal Reserve, the SEC, and the FBI.〔
