Blythe Masters, who will leave JPMorgan Chase & Co (JPM.N) after a 27-year career, is under investigation by federal prosecutors in Manhattan, Bloomberg reported citing two people with knowledge of the matter.
The probe was opened after a settlement last year with regulators that alleged JPMorgan manipulated power markets in the Midwest and California, the report said. (r.reuters.com/tur48v)
The bank agreed last July to pay $410 million to settle the case. While Masters was not cited for wrongdoing, her name appeared in the regulator's order a number of times.
It is not immediately clear what the Manhattan prosecutors are investigating.
JPMorgan was not immediately available for comment outside regular U.S. business hours.
Masters, who began her career at the bank with an internship in London, wanted to continue as the chief of the commodities business even after its sale to Geneva-based Mercuria Energy Group Ltd, Bloomberg said.
JP Morgan is selling its physical commodities to Mercuria for $3.5 billion and Masters is expected to leave the bank in a few months after assisting with the sale.
