Banks hold deposits and savings entrusted to them by individuals, by businesses, by governments and by central banks. They put that money to work, helping people to buy homes, for example, or lending to businesses to invest in expansion.

In our equities business, 49 of the 50 most important Lehman clients are back doing business with us. The flows are 75 to 80 per cent of what they were prior to the bankruptcy. The issues which damaged Lehman were around commercial mortgages and illiquid private equity assets.

Leverage is great when it works, and when it doesn't work, it creates a lot of issues. So I think if you limit the amount of leverage that people can borrow, or that banks can borrow, I think you'll find that you'll have a lot less issues going forward.

For a long time, I would go out of my way to have a personal appearance on the verge of an insane person, because it was closer to how I felt, but I looked so dumb. So, I just stopped. It was like, 'I'm just going to look like a banker.'
