The Federal Reserve took action on Wednesday against Goldman Sachs and one of its former executives, escalating a long-running investigation into a leak of confidential government information.

The action, which forced Goldman to pay a $36.3 million penalty, stemmed from an incident in 2014, when a junior Goldman banker took confidential information from the Federal Reserve Bank of New York. The junior banker, whom Goldman promptly fired, received the information from a New York Fed employee.

Both men pleaded guilty to stealing government property, and Goldman paid a $50 million penalty to New York State regulators because its “management failed to effectively supervise” the banker.

The Fed did not act against Goldman at the time, making its decision to pursue Goldman now a somewhat unusual move. The action, which cites Goldman for an “unauthorized use and disclosure of confidential supervisory information,” is also an awkward one for the Fed.
