Well, we have significant imbalances in certain housing markets.
I would say that, given how prices have grown ahead of economic fundamentals, there's certainly more risk of downside than risk of upside in housing markets. What we've done, the principal measure right now, in addition to strict underwriting.... The underwriting done in Canada by banks and by mortgage insurers is very strong.
People should not be worried about the stability of the financial system. As I said, our banks are sound. It's homeowners we should be worried about, because when prices fall, a number of these people will be exposed to very significant losses after paying real estate fees and insurance fees, and with very minimal equity. That risk of foreclosure is quite significant to homeowners, and people who lose their jobs—younger people tend to lose their jobs more quickly—could actually be exposed to great tragedy.
The problem is that this can accelerate upon itself. Housing markets are given to boom and bust cycles. Just as they run up, they run down. I know we don't think that's the case, but of the 46 financial crises for which we have housing data, two-thirds of them—this is globally—were preceded by housing boom and bust cycles in real estate.
Therefore, we should be worried about those homeowners. The stress test, which is something that creates a buffer above current mortgage rates, helps protect homeowners from that. It's an extra buffer that helps protect them from that eventuality.
