Three executives at JPMorgan Chase, the largest bank in the United States, are expected to leave their jobs this week after a $2 billion trading blunder, The Wall Street Journal reported Sunday.

The Journal, citing people familiar with the situation, reported that one of the executives is Ina Drew, who for seven years has run the risk-management division at the bank responsible for the loss.

A JPMorgan spokeswoman did not immediately return a request for comment from The Associated Press.

Earlier Sunday, NBC aired an interview in which JPMorgan CEO Jamie Dimon said that he was “dead wrong” when he dismissed concerns about the bank’s trading last month.

Dimon said he did not know the extent of the problem when he said in April that the concerns were a “tempest in a teapot.” After the bank reported the trading loss, investors shaved almost 10 percent off the bank’s stock price.
