Bloomberg data row escalates as JP Morgan demands records

THE Furore over how Bloomberg used client data intensified last night after JP Morgan said it had sent a formal legal request to the financial news agency to clarify what information reporters had access to.

The US bank, one of Bloomberg’s largest customers, said it was seeking logs for five years detailing what information on their employees’ use of terminals reporters had accessed.

JPMorgan said it was also seeking “confirmation” of controls that Bloomberg has put in place to stop future privacy breaches.

Bloomberg came under fire last week after it emerged reporters may have had access to users’ login details, functions and help desk inquiries.

Bloomberg’s editor-in-chief has apologised for the errors, saying reporters should never have had access to the information.
