Credit Risk Transfer and Financial Crises

Susan Wachter posted Credit Risk Transfer, Informed Markets, and Securitization to SSRN. It opens,

Across countries and over time, credit expansions have led to episodes of real estate booms and busts. Ten years ago, the Global Financial Crisis (GFC), the most recent of these, began with the Panic of 2007. The pricing of MBS had given no indication of rising credit risk. Nor had market indicators such as early payment default or delinquency – higher house prices censored the growing underlying credit risk. Myopic lenders, who believed that house prices would continue to increase, underpriced credit risk.

In the aftermath of the crisis, under the Dodd Frank Act, Congress put into place a new financial regulatory architecture with increased capital requirements and stress tests to limit the banking sector’s role in the amplification of real estate price bubbles. There remains, however, a major piece of unfinished business: the reform of the US housing finance system whose failure was central to the GFC. Fannie Mae and Freddie Mac, the government-sponsored enterprises (GSEs), put into conservatorship under the Housing and Economic Recovery Act (HERA) of 2008, await a mandate for a new securitization structure. The future state of the housing finance system in the US is still not resolved.

Currently, US taxpayers back almost all securitized mortgages through the GSEs and Ginnie Mae. While pre-crisis, private label securitization (PLS) had provided a significant share of funding for mortgages, since 2007, PLS has withdrawn from the market.

The appropriate pricing of mortgage backed securities can discourage lending if risk rises, and, potentially, can limit housing bubbles that are enabled by excess credit. Securitization markets, including the over the counter market for residential mortgage backed securities (RMBS) and the ABX securitization index, failed to do this in the housing bubble years 2003-2007.

GSEs have recently developed Credit Risk Transfers (CRTs) to trade and price credit risk. The objective is to bring private market discipline to bear on risk taking in securitized lending. For the CRT market to accomplish this, it must avoid the failures of financial assets to price risk. Are prerequisites for this in place? (2, references omitted)

Wachter partially answers this question in her conclusion:

CRT markets, if appropriately structured, can signal a heightened likelihood of systemic risk. Capital markets failed to do this in the run-up to the financial crisis, due to misaligned incentives and shrouded information. With sufficiently informed and appropriately structured markets, CRTs can provide market based discovery of the pricing of risk, and, with appropriate regulatory and guarantor response, can advance the stability of mortgage finance markets. (10)

Credit risk transfer has not yet been tested by a serious financial crisis. Wachter is right to bring a spotlight on it now, before events in the mortgage market overtake us.

Subprime v. Non-Prime

The Kroll Bond Rating Agency has issued an RMBS Research report, Credit Evolution: Non-Prime Isn’t Yesterday’s Subprime. It opens,

Following the private label RMBS market’s peak in 2007 and the ensuing credit crisis, non-agency securitizations of newly originated collateral have focused almost exclusively on prime jumbo loans. This is not surprising given the poor performance of loosely underwritten residential mortgage loans that characterized certain vintages leading up to the crisis. While legacy prime, in absolute terms, performed better than Alt-A and subprime collateral, it was apparent that origination practices had a significant impact on subsequent loan performance across product types.

Many consumers were caught in the ensuing waves of defaults, which marred their borrowing records in a manner that has either barred them from accessing housing credit, or at best made it extremely challenging to obtain a home loan. Others that managed to meet their obligations have been unable to qualify for new loans in the post-crisis era due to tighter credit standards that have been influenced by regulation.

The private label securitization market has not met the needs of these consumers for a number of reasons, including, but not limited to, reputational concerns in the aftermath of the crisis, regulatory costs, investor appetite, and the time needed for borrowers to repair their credit. The tide appears to be turning quickly, however, and Kroll Bond Rating Agency (KBRA) has observed the re-emergence of more than a dozen non-prime mortgage origination programs that intend to use securitization as a funding source. Of these, KBRA is aware of at least four securitization sponsors that have accessed the PLS market across nine issuances, two of which include rated offerings.

Thus far, KBRA has observed that today’s non-prime programs are not a simple rebranding of pre-crisis subprime origination, nor do they signal a return to the documentation excesses associated with “liar loans”. While the asset class is meant to serve those with less pristine credit, and can even have characteristics reminiscent of legacy Alt-A, it is expansive, and underwriting practices have been heavily influenced by today’s consumer-focused regulatory environment and government-sponsored entity (GSE) origination guidelines. In evaluating these new non-prime programs, KBRA believes market participants should consider the following factors:

■ Loans originated under sound compliance with Ability-To-Repay (ATR) rules should outperform 2005-2007 vintage loans with similar credit parameters, including LTV and borrower FICO scores. The ATR rules have resulted in strengthened underwriting, which should bode well for originations across the MBS space. This is particularly true of non-prime loans, where differences in origination practices can have a greater influence on future loan performance.

■ Loans that fail to adhere to GSE guidelines regarding the seasoning of credit dispositions (e.g. bankruptcy, foreclosure, etc.) on a borrower’s credit history should be viewed as having increased credit risk relative to those with similar credit profiles that lack recent disposition activity. This relationship likely depends on, among other things, equity position, current FICO score, and the likelihood that any life events relating to the prior credit issue remain unresolved.

■ Alternative documentation programs need to viewed with skepticism as they relate to the ATR rules, particularly those that serve borrowers with sub-prime credit histories. Although many programs will meet technical requirements for income verification, it is also important to demonstrate good faith in determining a borrower’s ability-to-repay. Failure to do so may not only result in poor credit performance, but increased risk of assignee liability.

■ Investor programs underwritten with reliance on expected rental income and limited documentation may pose more risk relative to fully documented investor loans where the borrower’s income and debt profile are considered, all else equal. (1, footnotes omitted)

I think KBRS is documenting a positive trend: looser credit for those with less-than-prime credit is overdue. I also think that KBRS’ concerns about the development of the non-prime market should be heeded — ensuring that borrowers have the ability to repay their mortgages should be job No. 1 for originators (although it seems ridiculous that one would have to say that). We want a mortgage market that serves everyone who is capable of making their mortgage payments for the long term. These developments in the non-prime market are most welcome and a bit overdue.

Better to Be a Banker or a Non-Banker?

 

The Community Home Lenders Association (CHLA) has prepared an interesting chart, Comparison of Consumer and Financial Regulation of Non-bank Mortgage Lenders vs. Banks.  The CHLA is a trade association that represents non-bank lenders, so the chart has to be read in that context. The side-by side-chart compares the regulation of non-banks to banks under a variety of statutes and regulations.  By way of example, the chart leads off with the following (click on the chart to see it better):

CLHA Chart

The chart emphasizes all the ways that non-banks are regulated where banks are exempt as well as all of the ways that they are regulated in the identical manner. Given that this is an advocacy document, it only mentions in passing the ways that banks are governed by various little things like “generic bank capital standards” and safety and soundness regulators. That being said, it is still good to look through the chart to see how non-bank regulation has been increasing since the passage of Dodd-Frank.

Mortgage Credit Conditions Easing

Home of Easy Credit

The Urban Institute’s Housing Finance Policy Center has released its July Housing Finance at a Glance. It opens,

Our latest update to HFPC’s Credit Availability Index (HCAI) shows early signs that the overly tight mortgage lending standards of the post-crisis period may finally be starting to ease. This HCAI update shows improvements for both GSE and FHA/VA channels. Between Q3 2013 and Q1 2015, the expected mortgage default rate increased from 1.8 to 2.1 percent (17 percent increase) for GSE originations, and from 9.6 to 10.8 percent (a 13 percent increase) for FHA/VA originations. The expected default rate for portfolio loans and PLS channels has remained largely flat at 2.6 percent over this period.

Long overdue, these improvements are largely a result of efforts to clarify put-back standards and conduct early due diligence. While the FHA has lagged the GSEs in these efforts, it has made some progress. Still, more needs to be done, especially to mitigate uncertain lender litigation risk arising out of FHA’s False Claims Act.

These improvements notwithstanding, there is still significant room to safely expand the credit box. Even if the mortgage market had taken twice the default risk it took in Q1 2015, that level would have still been below the level of default risk of the early 2000s. (3)

This excellent chartbook contains many very interesting graphs. I recommend that you look at the National Housing Affordability Over Time graph in particular. It shows that housing “prices are still very affordable by historical standards, despite increases over the last three years.” (16)

Treasury Gives RMBS a Workout

The Treasury has undertaken a Credit Rating Agency Exercise. According to Michael Stegman, Treasury

recognized that the PLS market has been dormant since the financial crisis partly because of a “chicken-and-egg” phenomenon between rating agencies and originator-aggregators. Rating agencies will not rate mortgage pools without loan-level data, yet originator-aggregators will not originate pools of mortgage bonds without an idea of what it would take for the bond to receive a AAA rating.

Using our convening authority, Treasury invited six credit rating agencies to participate in an exercise over the last several months intended to provide market participants with greater transparency into their credit rating methodologies for residential mortgage loans.

By increasing clarity around loss expectations and required subordination levels for more diverse pools of collateral, the credit rating agencies can stimulate a constructive market dialogue around post-crisis underwriting and securitization practices and foster greater confidence in the credit rating process for private label mortgage-backed securities (MBS). The information obtained through this exercise may also give mortgage originators and aggregators greater insight into the potential economics of financing mortgage loans in the private label channel and the consequent implications for borrowing costs.

While this exercise is very technical, it contains some interesting nuggets for a broad range of readers. For instance,

The housing market, regulatory environment, and loan performance have evolved significantly from pre-crisis to present day. Credit rating agency models appear to account for these changes in varying ways. All credit rating agency models incorporate the performance of loans originated prior to, during, and after the crisis to the degree they believe best informs the nature of credit and prepayment risk reflected in the market. Credit rating agency model stress scenarios may be influenced by loans originated at the peak of the housing market, given the macroeconomic stress and home price declines they experienced. The credit rating agencies differ, however, in how their models adjust for the post-crisis regime of improved underwriting practices and operational controls. Some credit rating agencies capture these changes directly in their models, while other credit rating agencies rely on qualitative adjustments outside of their models. (10)

It is important for non-specialists to realize how much subjectivity can be built into rating agency models. Every model will make inferences based on past performance. The exercise highlights how different rating agencies address post-crisis loan performance in significantly different ways. Time will tell which ones got it right.

Hockett on NYC Eminent Domain

Bob Hockett has posted ‘We Don’t Follow, We Lead’: How New York City Will Save Mortgage Loans by Condemning Them to SSRN. The abstract reads,

This brief invited essay lays out in summary form the eminent domain plan for securitized underwater mortgage loans that the author has been advocating and helping to implement for some years now. It does so with particular attention in this case to New York City, which is now actively considering the plan. The essay’s first part addresses the plan’s necessity. Its second part lays out the plan’s basic mechanics. The third part then systematically addresses and dispatches the battery of remarkably weak legal and policy arguments commonly proffered by opponents of the plan.

Hockett has been advocating this plan for some time in the face of concerted opposition from the financial industry. One industry argument that I have found to be over the top is that lenders will refuse to lend in communities that employ eminent domain to address the foreclosure crisis. Hockett writes,

Another policy argument made by some members of the securitization industry is that using eminent domain to purchase loans will dry up the sources of mortgage credit, rendering the American dream of homeownership unattainable. The financial services industry and its legislative supporters have made this kind of claim against regulatory and consumer protection proposals emerging from national, state, or municipal legislatures.

One problem with this argument is that private credit has not flowed to non-wealthy mortgage borrowers since the crash. Federal lenders and guarantors are nearly the only game in town, and they are likely to remain so until the underwater PLS loan logjam is cleared.

Another problem with the credit withdrawal argument is that it characterizes a benefit as a burden. The housing bubble was, like most of the more devastating bubbles through history, the upshot of an over-extension of credit. Lenders extended excess credit through reverse redlining and other predatory lending practices perpetrated or aided and abetted by participants in the securitization industry itself. Hence the securitization industry’s warning that credit might not be overextended in the future is a warning of something that might well be desirable. (142-43, footnotes omitted)

Given that lenders always rush to lend to countries that have recently defaulted on their sovereign debt, I don’t find the credit withdrawal argument to be particularly convincing here. But it may succeed in convincing some local governments not to proceed with their eminent domain strategies. I do hope, however, that at least one locality will follow through during the current foreclosure crisis. That way, we will at least have a proof of concept for the next foreclosure crisis.

 

Consumer Protection in RMBS 3.0

The Structured Finance Industry Group has issued RMBS 3.0:  A Comprehensive Set of Proposed Industry Standards to Promote Growth in the Private Label Securities Market.  This “green paper,” frequently referred to as a First Edition, states that RMBS 3.0 is an initiative

established with the primary goal of re-invigorating the “private label” residential mortgage-backed securities (“RMBS”) market.

Initiated by members of SFIG, the project seeks to reduce substantive differences within current market practices through an open discussion among a broad cross-section of market participants. Where possible, participants seek to identify and agree upon best practices. RMBS 3.0 focuses on the following areas related to RMBS:

  • Representations and warranties, repurchase governance and other enforcement mechanisms;
  • Due diligence, disclosure and data issues; and
  • Roles and responsibilities of transaction parties and their communications with investors. (1 footnotes omitted)

RMBS 3.0 is expected to

1. Create standardization where possible, in a manner that reflects widely agreed upon best practices and procedures.
2. Clarify differences in alternative standards in a centralized and easily comprehendible manner to improve transparency across RMBS transactions.
3. Develop new solutions to the challenges that impede the emergence of a sustainable, scalable and fluid post-crisis RMBS market.
4. Draft or endorse model contractual provisions, or alternative “benchmark” structural approaches, where appropriate to reflect the foregoing.(2)

There is much of interest in this attempt at self-regulation by the now quiescent but formerly roaring private-label market. But I think that readers of this blog would be interested in its approach to consumer protection regulation. First, the green paper refers to it as “consumer compliance.” (See, e.g., 23) Unsurprisingly, the paper is only concerned with protecting industry participants from liability for violations of consumer protection/consumer compliance laws. It pays no lip service to the spirit of consumer protection — promoting sustainable credit on transparent terms. That’s fine given the constituents of the SFIG, but it only confirms the importance of active consumer protection regulators and enforcement agencies who will look beyond rote compliance with regulations. The private-label industry is capable of rapid change once it gets going, change that can outpace regulations. Someone has to keep an eye on it with an eye toward to the principles that should guide a fair market for consumer credit.
