The Wall Street Journal listed those leaving as: Ina Drew, who since 2005 has run the risk-management unit that is responsible for the losses; Achilles Macris, who is in charge of the London-based desk that placed the trades; and trader Javier Martin-Artajo, a managing director on Mr. Macris's team.
Drew has run the risk-management division at the bank responsible for the loss for the past seven years.
People familiar with the matter also told the paper that trader Bruno Michel Iksil, nicknamed the "London Whale" for the big positions he took in credit markets, could depart as well but the timing is unclear.
All four executives declined to comment through the company, the paper said.
