As a result of the questioning regarding potential conflicts of interest, the New York-based bank has sharpened its disclosures to clients, the newspaper said, citing sources.
The Office of the Comptroller of the Currency, one of JP Morgan's regulators, has been in discussions with the bank regarding the potential conflicts of interest in recent months, according to the report. The matter may still be open, the report said.
"Being transparent is part of our normal course of business and it's what drives our client communications," Darin Oduyoye, a spokesman for JP Morgan's asset-management unit, told Reuters on Sunday.
If brokers push clients to buy the in-house brand of financial product, rather than provide impartial financial advice, the bank could stand to benefit at the expense of the client.
JP Morgan's Private Bank advisors are paid salary and bonus, not commission, Oduyoye said.
The Office of the Comptroller of the Currency did not immediately respond to a request for comment.
