Clearly you can't get interest rates below zero ... but we actually have interest rates now at 2-1/4 percent and clearly there is some room to lower them if it's needed.

... Furthermore, we are continually looking at steps to make the markets function better and I think we've been quite creative in terms of the steps we've taken so far, but in fact we will continue to look at the steps that we can take to in fact make the functioning of the financial markets get back to a more normal situation
