Home prices posted their strongest monthly gain on record in April, increasing more than 2.5 percent, according to the Case-Shiller Home Price Indices released Tuesday. The monthly 20-city index rose 2.5 percent in April, while the companion 10-city index increased 2.6 percent. Year-over-year, the 20-city index was up 12.1 percent, and the 10-city index was up 11.6 percent, each being the strongest yearly gain since March 2006.

The recent jump in home prices has led to speculation that the rapid surge in home prices could be the sign of a new housing bubble similar to the one that led to the Great Recession. Is it? The not-so-short answer is, not yet. An increase in prices itself does not signal a bubble. An unsustainable increase, not supported by other data, however, would. In the run-up to the 2006 collapse, the higher prices--which had been trending up for four years--led to a sharp uptick in construction wholly unsupported by demographics.

Existing-home sales rose a solid 4.2 percent in May to an annual sales rate of 5.18 million, the highest level since November 2009, the National Association of Realtors reported Thursday.

The inventory of homes for sale rose to 2.22 million from 2.15 million in April.

With a somewhat upbeat assessment of the economy, the Federal Open Market Committee (FOMC) said Wednesday it would continue its policy of near-zero interest rates and its $85-billion-per-month bond-buying program. In the statement issued at the conclusion of its two-day meeting, the committee said it ""sees the downside risks to the outlook for the economy and the labor market as having diminished since the fall,"" a more optimistic assessment than May 1 when the Committee said it ""continues to see downside risks to the economic outlook.""

One day after the National Association of Home Builders (NAHB) reported the sharpest boost in builder confidence in seven years, the Census Bureau and HUD reported single-family starts were essentially flat in May, increasing just 0.3 percent.

Builder confidence surged eight points in June to 52, its highest reading since March 2006, the National Association of Home Builders (NAHB) reported Monday. It was the first positive (above 50) reading for the association’s Housing Market Index (HMI) since April 2006. Two of the three components of the index--builder assessment of current sales and of sales six months in the future--were also positive. The current sales index rose eight points to 56, and the future sales index jumped nine points to 61.

In a newly published paper posted on the New York Federal Reserve website, Robert Hockett, a Cornell University professor of financial and monetary law, proposes using government's eminent domain authority as a solution to underwater mortgage debt. In reviewing Hockett's suggestion, the Wall Street Journal concentrated not on the idea itself, but on the fact that Hockett ""turns out to have been on the payroll of none other than Mortgage Resolution Partners."" There may be a lot of good reasons to discard Hockett's suggestion, but his past relationships are not among them. His idea deserves a fair hearing, not a digression.
