Authorities are set to slap banking giant JPMorgan Chase with a massive fine over the bank's huge trading losses in London last year, confirms NPR's Jim Zarroli.

Though details of the deal are still pending, several reports put the amount at more than $700 million. It comes on the heels of the bank's having recently paid $410 million to settle charges that it manipulated energy markets.

A federal jury in New York City has found that Fabrice Tourre, the former Goldman Sachs trader who regulators say caused investors to lose $1 billion, is liable in the mortgage securities fraud case filed against him by the Securities and Exchange Commission.

Regulators say Tourre, 34, a native of France who was nicknamed "Fab" in his office, packaged toxic subprime mortgages into a collateralized debt obligation that was sold to investors under the name Abacus in 2007.
