I think it's really important for people to understand that $1Bn isn't a lot of money to JPM because they do lots of things. They made $30Bn last year - but this specific trading business probably made nothing like that. They're doing consumer banking, investment banking, commercial banking, asset and wealth management. It might be true that $1Bn isn't a huge sum compared to the total profitability of JPM but I don't see why JPM's consumer banking arm has anything to do with the fine. Most likely these trading desks sum up to around 50-100 people at most. It's a very profitable sector (when you're breaking the law) but it's a tiny tiny part of what JPM do, and the idea that we should fine JPM more because they have lots of other businesses is just kind of crazy.
