See here for an article on Bloomberg which reports that JP Morgan are set to pay about $1bn to settle the matter of spoofing accusations that have been in the news for the last years (for example, see here). The matter relates to alleged spoofing in precious metals futures on Comex and Nymex over a period ranging from 2008 to 2016. This would be the largest penalty related to spoofing so far. Last month, Bank of Nova Scotia settled for $129.4m in another spoofing case related to precious metals (see here).
