In “Underwater Homeowners Here To Stay” we highlighted a report from Zillow which showed that negative equity has now become a permanent fixture of the US housing market. The report also showed that the percentage of homeowners who are underwater was flat from Q314 to Q414, breaking a string of 10 consecutive quarters of declines. We also recently noted that a completely ridiculous new home sales print that defied all logic notwithstanding, housing data, including starts and existing home sales, has come in below expectations. On a side note, home price appreciation has outpaced wage growth at a rate of 13:1, to which we would add: 

Of course, the biggest determinant of home price appreciation over the past 2 years has nothing to do with US consumers, or household formation, as confirmed by the collapse in first-time homebuyers or the unprecedented depression in new mortgage origination, and everything to do with what we first suggested is one of the main drivers of the US housing bubble - foreigners parking their illegally procured cash in the US and evading taxes, now that US housing, with the NAR's anti-money laundering exemption blessing, is the new normal's Swiss Bank Account. That and flipping homes from one "all-cash" buyer to another "all-cash" buyer in hopes of a quick capital appreciation and the constant presence of the proverbial dumb money.

Against this backdrop, Deutsche Bank is out predicting that a sluggish US housing market is likely to impact the supply of MBS going forward. As DB notes, housing isn’t the GDP contributor it once was and not by a long shot. Not only that, but when it comes to recoveries, the housing market’s GDP contribution was 7 times below its post WW2 average in year one and has fared even worse since. Here’s DB with more:

The contribution of housing to US GDP continues to run at some of the lowest levels since the end of World War II. New construction of single- and multi-family homes, renovations, broker fees and the like still only make up a bit more than 3% of current GDP, well below the post-war average of 4.7%. Not only has the level of lift from housing come in low, but it has bounced out of the last official recession slowly, too. Housing on average has contributed a half a percentage point to GDP a year after the end of every post-war US recession. This time around, housing added only 7 bp. And the contribution of housing in the second and third years after the recent recession also has fallen well below post-war averages.

And while “insufficient supply” (not enough homes) was cited as a possible contributor to the existing home sales miss, DB notes that at least as of today, there appears to still be a “supply hangover” (although it's waning):

US homeownership started the decade at 66.9%, peaked in 2004 at 69.2% and ended at 66.5%. It has since dropped to 64.0%. The exodus of owners initially threatened to leave a lot of extra houses behind and reduce the need to build new ones. But investors have come in to pick up the keys, and many houses have found a new home in the market for single-family rentals. This has helped reduce the supply of distressed homes, although it’s still higher than the levels that prevailed in the early 1990s when homeownership last ranged around 64% . The supply hangover isn’t done but should be in the next two or three years.

And demand isn’t looking so hot either: 

Demand has likely played a part in slow housing, too, starting with owners that bought their homes in the last decade. Thanks to a 38% drop in home prices nationally from 2006 to 2012, according to Case-Shiller, a lot of those owners walked out the front door without any equity and without the ability to reenter the market as buyers. This has almost certainly contributed to the drop in rental unit vacancies from 10.6% in mid-2009 to 7.0% today. As for potential new owners, Americans, even before the crisis, started moving into their own place at a much slower pace than the long-term average of 1.2 million new households a year, that is, until recently. Demand from former and potential new owners has been soft.

Even in the best case scenario is which supply falls and demand rises, banks’ reluctance to lend could end up hobbling the market for the foreseeable future. 

Although the market seems to be clearing out the lingering housing supply and the economy and the labor market look likely to repair demand, the availability of credit could prove to be the lasting constraint. Today’s lending standards reflect limits designed to keep the last decade’s boom and bust from happening again. Borrowers today without the ability to repay will not get a loan. But it looks like some borrowers with the ability to repay—but with low FICO scores or with needs that keep them outside the agency or prime jumbo markets—will also not get a loan. The market is reducing risk today to avoid risk tomorrow. But it also is likely reducing housing growth today to avoid a downturn tomorrow. 

And here's further confirmation of this from BofAML:

So there is your housing recovery in a nutshell: supply hangover, lackluster demand, and reluctant lenders all coalescing in a housing market whose contribution to US economic growth is virtually nonexistent. 

And if you’re looking for the next shoe to drop, here’s a hint:
