The US bank JPMorgan Chase is facing a $ 1 billion fine. The bank would be about to settle with the US authorities following an investigation into market manipulation, reporting sources around the bank to Bloomberg press office. JPMorgan would have tampered with the trade in metals and bonds. The settlement announcement will probably take place later this week. This would be the highest fine ever imposed on such practices. It is certainly not the first time that the bank has been haunted by this kind of legal hassle. JPMorgan had to pay billions in fines and damages in 2013 and 2014, including for fraud, market manipulation and deception of customers and investors.
