Yellen, Janet

While it's likely that the slowdown in the housing sector will have only moderating effects on economic activity and will continue to unfold in an orderly way, I should note that we can't ignore the risk that a more unpleasant scenario might develop. In particular, we have heard a lot in recent years about the possibility that there is a house-price "bubble," implying that prices got out of line with the fundamental value of houses and that the current softening could be just the beginning of a steep fall. While I doubt that we'll see anything like a "popping of the bubble"—in part because I'm not convinced there is a bubble, at least on a national level—it is a risk we have to watch out for.
