Housing rebound in Canada spurs talk of new bubble (Dvorak, WSJ) Last week Paul Krugman toasted the sobriety of Canadian banks. Among other things, he said that low rates aren’t enough to cause a bubble since Canadian rates are low and, well, they don’t have a bubble. If this article is to be believed, Krugman didn’t look closely enough. Banks may use less leverage in Canada, but low rates are encouraging households to borrow big — debt to disposable income is a bubbly 1.42x. Key quote in this piece is near the bottom, where a real estate agent notes that rising prices mean rents are only barely covering mortgage payments for real estate investments. The best definition of a bubble is when debt service payments finally eclipse rents. Then buyers/lenders are betting on continued appreciation, which can only be driven by still-easier credit. Canadian real estate appears to be headed in that direction.
