Countercyclical Regulation of Housing Finance

Posted on by

Pat McCoy has posted Countercyclical Regulation and Its Challenges to SSRN. The abstract reads,

Following the 2008 financial crisis, countercyclical regulation emerged as one of the most promising breakthroughs in years to halting destructive cycles of booms and busts. This new approach to systemic risk posits that financial regulation should clamp down during economic expansions and ease during economic slumps in order to make financial firms more resilient and to prick asset bubbles before they burst. If countercyclical regulation is to succeed, however, then policymakers must confront the institutional and legal challenges to that success. This Article examines five major challenges to robust countercyclical regulation – data gaps, early response systems, regulatory inertia, industry capture, and arbitrage – and discusses a variety of techniques to defuse those challenges.

Readers of this blog will be particularly interested in the section titled “Sectoral Regulatory Tools.” (34 et seq.) This section gives an overview of countercyclical tools that can be employed in the housing finance sector:  loan-to value limits; debt-to-income limits; and ability-to-repay rules. McCoy ends this section by noting,

The importance of the ability-to-repay rule and the CFPB’s exclusive role in promulgating that rule has another, very different ramification. It is a mistake to ignore the role of market conduct supervisors such as the CFPB in countercyclical regulation. The centrality of consumer financial protection in ensuring sensible loan underwriting standards – particularly for home mortgages – underscores the vital role that market conduct regulators such as the CFPB will play in the federal government’s efforts to prevent future, catastrophic real estate bubbles. (44)

While this seems like an obvious point to me — sensible consumer protection acts as a brake on financial speculation — many, many academics who study financial regulation disagree. If this article gets some of those academics to reconsider their position, it will make a real contribution to the post-crisis financial literature.

SEC Update on Rating Agency Industry

Posted on by

The staff of the U.S. Securities and Exchange Commission has issued its Annual Report on Nationally Recognized Statistical Rating Organizations. The report documents some significant problems with the rating agency industry as it is currently structured. The report highlights competition, transparency and conflicts of interest as three important areas of concern.

Competition. There are some of the interesting insights to be culled from the report. It notes that “some of the smaller NRSROs [Nationally Recognized Statistical Rating Organizations] had built significant market share in the asset-backed securities rating category.” (16) That being said, the report also finds that despite “the notable progress made by smaller NRSROs in gaining market share in some of the ratings classes . . . , economic and regulatory barriers to entry continue to exist in the credit ratings industry, making it difficult for the smaller NRSROs to compete with the larger NRSROs.” (21)

Transparency. The report also notes that “there is a trend of NRSROs issuing unsolicited commentaries on solicited ratings issued by other NRSROs, which has increased the level of transparency within the credit ratings industry. The commentaries highlight differences in opinions and ratings criteria among rating agencies regarding certain structured finance transactions, concerning matters such as the sufficiency of the credit enhancement for the transactions. Such commentaries can serve to enhance investors’ understanding of the ratings criteria and differences in ratings approaches used by the different NRSROs.” (23) The report acknowledges that this is no cure-all for what ails the rating industry, it is a positive development.

Conflicts of Interest.Conflicts of interest have been central to the problems in the ratings industry, and were one of the factors that led to the subprime bubble and then bust of the 2000s.  The report notes that the “potential for conflicts of interest involving an NRSRO may continue to be particularly acute in structured finance products, where issuers are created and operated by a relatively concentrated group of sponsors, underwriters and managers, and rating fees are particularly lucrative.” (25) There is no easy solution to this problem and it is important to carefully study it on an ongoing basis.

The staff report is valuable because it offers an annual overview of structural changes in the ratings industry. This year’s report continues to highlight that the structure of the industry is far from ideal. As the business cycle heats up, it is important to keep an eye on this critical component of the financial system to ensure that rating agencies are not being driven by short term profits for themselves at the expense of long-term systemic stability for the rest of us.

Mortgage Leverage and Bubbles

Posted on by

Albert Alex Zevelev has posted Regulating Mortgage Leverage: Fire Sales, Foreclosure Spirals and Pecuniary Externalities to SSRN. The abstract reads,

The US housing boom was accompanied by a rise in mortgage leverage. The subsequent bust was accompanied by a rise in foreclosure. This paper introduces a dynamic general equilibrium model to study how leverage and foreclosure affect house prices. The model shows how foreclosure sales, through their effect on housing supply, amplify and propagate house price drops. A calibration to match the bust shows consumption and housing need to be sufficiently complementary to fit the data. Since leverage plays a key role in foreclosure, a regulator can reduce systemic risk by placing a cap on leverage. Counterfactual experiments show that in a world with less leverage, the same economic shock leads to less foreclosure and less severe, shorter busts in house prices. A 90% cap on loan-to-value ratios in 2006 predicts house prices would have fallen 12% rather than 18% as in the data. The regulator faces a trade-off in that less leverage means less housing for constrained households, but also fewer foreclosures and less severe busts in house prices. A regulator with reasonable preference parameters would choose a cap of 95%.

This is pretty important stuff as it attempts to model the impact of different LTV ratios on prices and foreclosure rates. Now Zevelev is not the first to see these interactions, but it is important to  model how consumer finance regulation (for instance, loan to value ratios) can impact systemic risk. This is particularly important because many commentators downplay that relationship.

I am not in a position to evaluate the model in this paper, but its conclusion is certainly right: “Leverage makes our economy fragile by increasing the risk of default. It is clear that
foreclosure has many externalities and they are quantitatively significant. Since borrowers
and lenders do not fully internalize these externalities, there is a case for regulating mortgage leverage.” (31)

Lifting a Shadow from Qualified Residential Mortgages

Posted on by

The self-named Shadow Financial Regulatory Committee of the American Enterprise Institute has issued a statement on The New Qualified Residential Mortgage Rule Proposal.  The Shadow Committee argues that agencies promulgating the newest version of the QRM rule

completely abandoned the Act’s requirement for a separate high-quality QRM. Instead, they proposed a QRM that was essentially the equivalent of the QM. This not only violated the congressional intent and nullified the retainage, but it pushed the US mortgage system back toward the very policies that fed the housing bubble, the mortgage meltdown and the financial crisis. It responds to those want the mortgage finance system to make mortgage credit widely available, but it ignores the need for a stable system that will avoid a future crisis. (2)

This is not fully accurate. The QRM proposal does not violate congressional intent because Congress merely stated that the QRM be “no broader” than the QM. (Dodd-Frank Act Section 941) There is also a fair amount of fear-mongering here because the Shadow Committee does not propose how we can responsibly balance credit availability with systemic stability.

Nonetheless, the Shadow Committee is right to note that the rules governing mortgages must balance a number of competing goals.
When the proposed rule was released, I had written that it should incorporate a “benefit ratio” which

compares “the percent reduction in the number of defaults to the percent reduction in the number of borrowers who would have access to QRM mortgages.” (20) A metric of this sort would go a long way to ensuring that there is transparency for homeowners as to the likelihood that they can not only get a mortgage but also pay it off and keep their homes.

A benefit ratio would not only help ensure that homeowners received sustainable mortgages, but it would also address the systemic concerns raised by the Shadow Committee. This is because the benefit ratio would protect lenders from their own worse instincts as they lower their underwriting standards in pursuit of increased market share in a booming market.

The GAO’s Take on The FHA

Posted on by

The Government Accountability Office issued an update to its 2013 HIGH-RISK SERIES.  It had this to say about the Federal Housing Administration:

a new challenge for the markets has also evolved as the decline in private sector participation in housing finance that began with the 2007-2009 financial crisis has resulted in much greater activity by FHA, whose single-family loan insurance portfolio has grown from about $300 billion in 2007 to more than $1.1 trillion in 2012. Although required to maintain capital reserves equal to at least 2 percent of its portfolio, FHA’s capital reserves have fallen below this level, due partly to increases in projected defaults on the loans it has insured. As a result, we are modifying this high-risk area to include FHA and acknowledge the need for actions beyond those already taken to help restore FHA’s financial soundness and define its future role. One such action would be to determine the economic conditions that FHA’s primary insurance fund would be expected to withstand without drawing on the Treasury. Recent events suggest that the 2-percent capital requirement may not be adequate to avoid the need for Treasury support under severe stress scenarios. Additionally, actions to reform GSEs and to implement mortgage market reforms in the Dodd-Frank Act will need to consider the potential impacts on FHA’s risk exposure. (25)

Discussion about the FHA is getting in high gear, in large part because of Ed Pinto.  I expect to take up the issue of the FHA’s appropriate role in the housing market over the coming months and will offer an alternative vision to his.
