I think Lloyd is very open minded. Totally different for Jamie.
Different agendas. It's obvious that JPMorgan CEO was/is just abusing his bank's status to cause panic in the market, but he hasn't exactly succeeded in doing so.
At this point it can't yet be considered market manipulation officially (while in reality it's exactly that), but with more regulations on the way, this is something that will definitely change at some point, and become a punishable offence.
Especially when they are involved into certain by the SEC approved future markets. After all, it's just a matter of time before we see an ETF come through, or maybe CME to get its approval, so the doors to institutions are almost open.
