Here in Canada, for example, we have strengthened the rules around the mortgage market in several ways. Those changes, combined with very high-quality underwriting even before those changes were made, make the Canadian situation very different from what we saw in the United States just before the crisis.
That being said, some critics would still say that we are running the risk of creating the next financial crisis through our actions. I might ask in response: What is it you would have us do, then? As the central bank, we only have one real channel of influence, which is to set short-term interest rates.
