It is actually our role to understand those things; however, it's OSFI's role to regulate our banks to ensure that they're meeting their requirements. The big picture, I think, of what went wrong in the lead-up to the financial crisis shows that it was leverage. There was a great deal of leverage out there that puffed up financial markets and led to a domino effect as things started to unwind.
Leverage doesn't disappear just because the crisis is over. When we go back to last spring, when the first mention of tapering happened and financial markets had a lot of volatility, that was again because there is leverage in certain areas of the market in which it looks easy, if the risk is low and you can stack up your position by leveraging it, to earn returns of multiple times in that situation.
Leverage is a fact of life in the financial markets. Part of the new Basel package, if you like, that the FSB, Financial Stability Board, is working through, is to ensure that there are limits on the leverage that banks can undertake. Those limits will actually be limiting, compared with what we saw in the run-up to the crisis.
We are in the process of developing an entirely new international financial architecture that already feels much safer than what we were living with before. It is not yet done. As a lead-up to the summit in Australia later this year, I would say that we're looking at probably 80% of the job being done, and that's a pretty significant step forward. There still will be new developments on the regulatory front.
Tiff, would you like to add something?
