Javier Martin-Artajo and Julien Grout will probably be taken into custody in London in coming days, the newspaper reported. An attorney for Martin-Artajo didn’t immediately reply to requests for comment from Bloomberg News. An attorney for Grout and spokesmen for the Federal Bureau of Investigation and US Attorney’s Office declined to comment.

Prosecutors determined that Martin-Artajo and Grout, who worked in a London unit that lost more than US$6 billion (RM19.52 billion) last year, falsified records and concealed losses from their managers in New York, the newspaper’s report said. The case hinges on help from Bruno Iksil, who was dubbed the London Whale because of his trading positions’ outsized effects on credit-derivative markets, according to the New York Times.

Iksil, who some investigators decided had been unfairly blamed for the losses, met with authorities in Brussels and New York and secured a cooperation agreement with the US government, the newspaper reported. It isn’t clear whether he could face charges, according to the paper.

An attorney for Iksil didn’t immediately respond to a request for comment from Bloomberg News. Joseph Evangelisti, a spokesman for JPMorgan in New York, declined to comment.

JPMorgan, the biggest US bank by assets, is also negotiating the final terms of a deal with the Securities and Exchange Commission to end a yearlong probe of the trading loss, two people briefed on the talks said on August 8.

The bank, led by Chief Executive Officer Jamie Dimon, is seeking to resolve US and UK probes after botched trades by its chief investment office led to the losses and an earnings restatement. Senate investigators concluded in March that the bank dodged regulators and misled investors about the souring bets.

JPMorgan’s own 129-page report on the losses, released in January, found that London traders initially tried to hide losses on the positions. The employees left the bank and the bank sought to claw back pay. The report also blamed managers, some of whom were reassigned or left the bank, for failing to halt the losses.

Martin-Artajo, who supervised Iksil, in January settled a London lawsuit brought against him by the bank, a person with direct knowledge said at the time. The bank sued Martin-Artajo in October without detailing its allegations in filings. — Bloomberg
