With all of that in mind, it is very clear that the Bank of Canada is looking to Ottawa to rein in consumer debt. They have made some clear policy suggestions in this paper, and you can bet that Jim Flaherty and Stephen Harper will be hearing all about them:
Recent international discussions have begun to examine the merits of adjusting mortgage market rules over time. For example, country authorities could change the maximum LTV ratio in acountercyclical fashion, lowering it during housing booms and raising it when house prices are depressed. One outcome of this type of policy is an increase in the resilience of the financial system since it requires borrowers to have a larger equity stake in their property during booms, thus reducing the potential losses to financial intermediaries during the bust phase when income and house prices fall. In addition, the lower LTV ratio (higher down payment) would act against the boom in the first place by reducing the extent to which borrowers could extract equity from their homes or take on more leverage to buy a bigger home.
Christensen and Meh (forthcoming) investigate the role of a time-varying maximum LTV ratio in a model based on Christensen et al. (2009).13 They consider the impact when the public authorities respond to a credit boom by lowering the regulatory maximum LTV ratio below its long-run setting of 80 per cent. The extent of the countercyclical response of the LTV ratio is determined by a regulatory rule that links the change in the LTV ratio to the level of mortgage credit relative to its long-run value. Housing booms and busts are often attributed, at least in part, to an easing of mortgage-underwriting conditions. We now turn to the case in which lenders themselves supply more credit and consider how the outcome might differ if the LTV ratio was lowered in response.
And with that, the Harper government has just felt the heat to adjust down payments. This move, coupled with the reinstitution of the regional maximum mortgage ceiling by CMHC would go a long way in letting air out of this exceptionally buoyant market and limiting consequences in the future.Expect a flood of rebuttals from the mortgage industry...
