JPMorgan Chase & Co.’s (JPM) wrong-way bets on derivatives are the focus of an escalating probe by a U.S. Senate panel led by Carl Levin that has grilled executives from banks including Goldman Sachs Group Inc. and HSBC Holdings Plc, three people briefed on the inquiry said.

Levin’s Permanent Subcommittee on Investigations is seeking testimony from people who worked in or helped lead JPMorgan’s chief investment office, according to the people, who declined to be identified because the inquiry isn’t public. The unit’s London staff lost at least $5.8 billion this year on the botched bets, which were large enough to shift markets.        Source: Bloomberg
