Do rising rents complicate inflation assessment?

In the face of falling house prices, decreasing rates of homeownership, and a glut of vacant homes, the Consumer Price Index’s measure of the cost of owner-occupied housing—owners’ equivalent rent of residence (OER)—has begun to accelerate, rising at an annualized rate of 2.3 percent over the past six months. Given a backdrop of generally subdued underlying inflation elsewhere in the index, a persistent increase in the relative price of OER—the largest component of the consumer market basket by far—may create upward pressure on measured inflation.
