“I don’t know where he wants this to stop. But it’s getting idiotic.”

These are the words of the then-JPMorgan trader Bruno Iksil,  known as the “London Whale” for his risky trades, according to a new Senate probe.

Iksil presided over trades that lost some $6 billion. The report says the Whale wanted to cut losses and get out, but Bigger Whales, his managers, told him to keep betting.

Financial analyst Josh Rosner at Graham Fisher is co-author of Reckless Endangerment.

“The company helped to paint it as a  problem of traders, that they had thrown the traders overboard. And that, as Jamie Dimon has claimed, the Whale has been killed and harpooned,” says Josh Rosner, a financial analyst at Graham Fisher and co-author of the book Reckless Endangerment. “And here we are finding well hold on it goes all the way to the front office.”

According to the report, top managers at JPMorgan also barreled through internal stop signs warning of financial risk and hid losses from the public.

Rosner says the broader failure is risk controls at all banks. Today’s hearing focuses again on big banks and regulating them.

As a preview, one senator notes “they are not too big to jail.”
