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.

First-Time Homebuyers, You’re Okay

Couple Looking at Home

Saty Patrabansh of the Office of Policy Analysis and Research at the Federal Housing Finance Agency has posted a working paper, The Marginal Effect of First-Time Homebuyer Status on Mortgage Default and Prepayment.

While this is a dry read, it yields a pretty important insight for first-time homebuyers: you’re okay, just the way you are! The abstract reads,

This paper examines the loan performance of Fannie Mae and Freddie Mac first-time homebuyer mortgages originated from 1996 to 2012. First-time homebuyer mortgages generally perform worse than repeat homebuyer mortgages. But first-time homebuyers are younger and have lower credit scores, home equity, and income than repeat homebuyers, and therefore are comparatively less likely to withstand financial stress or take advantage of financial innovations available in the market. The distributional make-up of first-time homebuyers is different than that of repeat homebuyers in terms of many borrower, loan, and property characteristics that can be determined at the time of loan origination. Once these distributional differences are accounted for in an econometric model, there is virtually no difference between the average first-time and repeat homebuyers in their probabilities of mortgage default. Hence, the difference between the first-time and repeat homebuyer mortgage defaults can be attributed to the difference in the distributional make-up of the two groups and not to the premise that first-time homebuyers are an inherently riskier group. However, there appears to be an inherent difference in the prepayment probabilities of first-time and repeat homebuyers holding borrower, loan, and property characteristics constant. First-time homebuyers are less likely to prepay their mortgages compared to repeat homebuyers even after accounting for the distributional make-up of the two groups using information known at the time of loan origination.

So, just to be clear, being a first-time homebuyer is not inherently risky. Rather, the risks arising from transactions involving first-time homebuyers are the same as those involving repeat homebuyers:  loan characteristics, property characteristics and other borrower characteristics.

Treasury Gives RMBS a Workout

Posted on by

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.
