On Wednesday, Channel 4 News economics editor Paul Mason went on a rant after six banks were fined £2.6 billion following attempts by traders to manipulate foreign exchange rates.
He adds:
Well, I'm here again at RBS because yet again they've done something wrong, but they're not the only ones.
There's five UK banks whose foreign exchange traders ripped off their own clients.
If the banks had the same scrutiny over the traders and their own managers as they have over the camera crew standing outside it, where you get a security guard asking you what you're doing, we might not be in this situation.
Mason questions how the managers who ran the banks from 2008 until 2012/13 managed to escape with their reputations unscathed.
Mason concludes:
All we ask, all we can ask, is that the regulators do their job proactively. That they actually get on the case – just like the security guards outside here, and the CCTV cameras there, and the City of London police – they get on the case and stop wrongdoing. What's so hard about it?
