A representative for JPMorgan declined to comment, and Koo didn’t respond to requests for comment.
(Jan 14): One of JPMorgan Chase & Co’s most senior credit traders has become the latest Wall Street veteran to get swept up in the industry’s concern over the use of WhatsApp.
Edward Koo, who has spent almost 20 years at the firm, was placed on leave as the bank reviews whether he broke its policies by using WhatsApp group chats with colleagues, according to people with knowledge of the matter. The discussions included market chatter, and the probe so far hasn’t indicated any improper activity, according to a person familiar with the investigation. The bank hasn’t ruled out taking action against other members of the group, one of the people said.
