Higher Rates, Smarter Models, and Fresher Credit Insights: August Models & Markets Recap

Register here for next month’s call: Thursday, September 18th, 2025, 1 p.m. ET. 

Each month, we host a Models & Markets call to offer our insights into recent model performance, emerging credit risks, and broader economic indicators. This month’s call was a wide-ranging update on new model developments, consumer credit insights, and macroeconomic trends shaping structured finance. 

Here’s a quick recap in case you missed it. 

(Click here to listen to the entire 30-minute recording or continue reading for a summary.)  

Market Outlook: August 2025

Stable employment and inflation notwithstanding, the macro backdrop remains dominated by persistent headwinds: 

  • Mortgage Rates: Still above 6.5% and expected to stay above 6% for the next several years. 
  • Home Prices: Case-Shiller data shows relative stability, with modest month-over-month declines and low year-over-year growth. 
  • Labor & Inflation: Both unemployment and PCE inflation are holding steady. 
  • Fed Policy: The Fed Funds Rate remains in the 4.25%–4.50% range, with the first cut expected in September 2025. Markets anticipate a year-end rate of 3.75%–4.00%, but long-term rates remain elevated. 
  • 10Yr rates unlikely to see a significant decline over next few years, leading to a high mortgage rate environment (>~ 6%) for next 3-5 years. 

New Equifax Data Integration 

We introduced our latest research leveraging the Equifax Analytic Dataset (ADS), a borrower-level anonymized sample representing 10% of the U.S. active credit population. Using tradeline-level detail (credit scores, balances, payments, etc.), we have constructed aging curves for auto loans and personal loans segmented by credit score bands. 

Some key takeaways: 

  • Auto Loan Defaults: Clear segmentation appears across credit score bands, with default curves validated against Federal Reserve data. 

  • Personal Loan Defaults: Similar segmentation trends, with early results indicating significant variation across risk tiers. 
  • Credit card and student loan performance curves: Coming soon. 

The final versions of these datasets will be accessible directly within the RiskSpan platform, allowing clients to benchmark their portfolios against robust national trends. 

Model Updates 

Prepayment Models (Versions 3.2 & 3.7) 

Our prepayment models continue to perform strongly against observed market behavior. The latest back-testing of agency cohorts (Fannie Mae and Freddie Mac 2021/2022 vintages across 1.5%–6.5% coupons) shows that speeds remain broadly consistent with expectations. However, higher coupon pools have recently exhibited slower-than-expected speeds, reflecting both tighter refinancing conditions and borrower credit constraints. 

1.5 to 3.5 Coupons 

6.5 Coupons 

Credit Model 7.0 

Our much-anticipated Credit Model v7 is now available in production on the RiskSpan Platform. Key features include: 

  • Delinquency Transition Matrix – A granular 3-D framework tracking monthly movement of loans through delinquency buckets (30D, 60D, 90D, 120D, 150D, 180D+, Foreclosure, REO). 
  • Severity & Liquidation Enhancements – Expanded severity vectors and a liquidation timeline module allow for more nuanced control of loss projections. 
  • Integration with MSR Engine – Provides detailed P&I and T&I cash flow accounting that captures probabilistic delinquency transitions. 

These enhancements equip investors and risk managers with deeper tools for analyzing loss dynamics across mortgage, GSE, FHA, and VA loan cohorts.

Monitoring Non-QM Mortgage Delinquencies in a Shifting Market

This post provides an update on delinquency rate trends observed in the Non-Agency mortgage market with a deep dive on different segments of the fast growing Non-QM mortgage market. All of the figures in this post are based on queries of historical CoreLogic Non-Agency data via our proprietary RiskSpan Edge Historical module.

After reaching post-Covid highs in May 2025, delinquency rates have stabilized at slightly lower levels in August 2025, the most recent factor date available from CoreLogic: 

  • As shown in figures 1 and 2, the 60+ delinquency rate for Private Label Securities 2.0 (loans originated after 2010) is 2.21%, while the DQ rate for Legacy products (originated prior to 2010) continues to fall below the 10% threshold, hitting a post-COVID low of 9.61% 
  • Prime Jumbo mortgages continue to demonstrate the strongest performance from a credit perspective, with delinquency rates at 0.57%. 
  • 2nd Lien loans, comprising HELOCs and closed end mortgages, had a delinquency rate of 1.01%. 
  • Non-QM loans saw delinquency rates remain stable at 3.05%, slightly below the post-COVID peak of 3.17% in May.  

Figure 1. 

Figure 2.

Figure 3 shows the relative delinquency performance of mortgages across 4 segments of the Non-QM population, which represents the largest portion of the PLS 2.0 market. While loans with full documentation represent the largest segment of this market from a total outstanding balance perspective, originations have been shifting towards DSCR/Investor and Bank statement loans since 2022 (see Figure 4). In 2025, the combined volume of originations in the DSCR/Investor and Bank statement segments was about four times the volume of loans originated with full documentation. 

  • Fully documented loans have the lowest 60+ delinquency rate at 0.89%, though as this segment seasons, the DQ rate continues to creep up from the post-COVID lows of 0.39% seen in October 2022. 
  • Delinquency rates for DSCR/Investor and Bank Statement loans stabilized in August at 3.34% and 4.41% respectively, slightly lower than their post-COVID peaks seen in May 2025  

Figure 3. 

Figure 4. 

Figures 5 and 6 show the relative delinquency performance of Non-QM mortgages by year of origination. For these charts, we exclude vintages prior to 2021 to avoid the distorting impact of the COVID delinquency shock. 

Figure 5 shows the 60+ delinquency rate for each vintage by factor date. 

  • The delinquency rate for the 2023 vintage hit 5.25% in August, surpassing 2022 as the vintage with the highest delinquency rate. 
  • In spite of being the most seasoned, the 2021 vintage’s 2.04% DQ rate was significantly lower than the subsequent 2022 and 2023 vintage. This is largely due to the disproportionately high share of full documentation loans in this first post-COVID cohort of Non-QM rates, which can be seen in Figure 4. By contrast, the 2022 and 2023 vintages  are composed primarily of the higher risk DSCR and Bank Statement originations. 

Figure 6 shows the 60+ delinquency rate for each vintage by loan age.

  • Consistent with the trends observed in Figure 5, we see the 2023 vintage DQ rates ramp up faster than any of the other vintages. 
  • The 2024 vintage is tracking between the 2022 and 2023 vintages. 
  • While there are only a few months of observations available the 2025 vintage, its delinquency ramp-up is tracking with the other post-2021 vintages 

Figure 5. 

Figure 6.

Given the elevated delinquency rates of Non-QM mortgages relative to Agency and Prime Jumbo mortgages and the backdrop of housing and macroeconomic uncertainty, it is important for investors to monitor their portfolios that have Non-QM exposure. Our credit models at RiskSpan model these delinquency roll rates directly, and our modeling team calibrates our suite of models to capture both the overall trends and the differentiated performance across loan and product types. These models are just one component of our scaled analytics solutions to help our clients evaluate risk and make investment decisions.

Navigating Headwinds with Data and AI: July Models & Markets Recap

Register here for next month’s call: Thursday, August 21st, 2025, 1 p.m.

Each month, we host a Models & Markets call to offer our insights into recent model performance, emerging credit risks, and broader economic indicators. This month, as interest rates remain elevated and economic uncertainty persists, we addressed how both conventional and AI-based modeling techniques are shaping decision-making processes across agency, non-QM, and ARM products.

Here’s a quick recap in case you missed it.

(Click here to listen to the entire 30-minute recording, or continue reading for a summary.)

Model Performance: Prepayment Dynamics in Focus

RiskSpan’s prepayment model continues to perform well based on benchmarking against actuals across coupon stacks. The team noted:

  • Speeds in higher coupons have slowed relative to expectations, in line with broader refinancing trends as mortgage rates remain high.
  • RiskSpan’s Non-QM Prepayment Model (v3.11) shows strong back-testing performance. While most vintages perform as expected, the 2022 vintage diverged, potentially due to ambiguous underwriting guidelines in QM loans that may have led to adverse selection in the Non-QM space. One possible reason is that this reflects borrower composition differences not captured by traditional metrics.

New ARM Model Launch

An enhanced ARM Prepayment Model (v3.8) is now live in production. It exhibits refined sensitivity to rate shocks and aims to provide improved accuracy for adjustable-rate portfolios in today’s volatile environment.

Claude the Research Assistant: AI in Action

One of the highlights of the call was a deep dive into how we are testing Claude (Anthropic’s well-known LLM) as a mortgage research assistant.

Using a dataset from RiskSpan’s Snowflake instance, Claude orchestrated an end-to-end analytical workflow, including:

  • Retrieving and aggregating partially pre-aggregated loan-level data
  • Generating Python code for analysis and visualization
  • Annotating charts and analyzing prepayment trends

Key Insights from Claude’s Analysis

Claude surfaced several noteworthy trends:

  • FICO Score Sensitivity: Higher credit score bands (>750) showed dramatically higher prepayment rates than lower bands (<650), highlighting the refinancing advantage for more creditworthy borrowers.
  • Loan Size Effect: A positive correlation (0.22) between loan size and prepayment rates suggests that larger loan holders are more motivated to refinance.
  • Mortgage Vintage: Newer vintages (especially 2015–2016) demonstrated greater prepayment sensitivity, likely due to looser underwriting and seasoning effects.
  • Interest Rate Sensitivity: Claude captured the sharp inverse relationship between rates and prepayment, particularly the COVID-era spike and the post-2022 slowdown.

Claude correctly reasoned with the provided data but could not identify some features (like “Spread at Origination”). This raises interesting questions about LLMs’ capacity to reason beyond their training corpus.

Market Outlook: Economic Signals Turning Cautionary

The macro backdrop continues to weigh on securitization and borrower behavior. Highlights from July’s indicators:

  • Mortgage Rates: Remain above 6.5%, with little sign of easing before the Fed’s expected first rate cut in September.
  • Fed Funds Rate: Currently 4.25–4.50%, with year-end projections settling around 3.75–4.00%.
  • Home Prices: Showing stability with little YoY movement in the Case-Shiller Index.
  • Labor and Inflation: Both unemployment and PCE inflation measures remain steady, but signs of economic headwinds are beginning to appear.

On the Horizon

  • RiskSpan’s new credit model (v7), which includes a new delinquency transition matrix, is on track for release by the end of the month.
  • Continued enhancements are being made to the Platform, including new prepayment and performance visualizations for private credit and agency MBS sectors.

Humans in the Loop: Ensuring Trustworthy AI in Private ABF Deal Modeling

As generative AI becomes a powerful tool in Private asset-backed finance (ABF), the need for precision and transparency is more critical than ever. At RiskSpan, we’re applying Large Language Models (LLMs) to automate and accelerate private ABF deal modeling and surveillance. But speed is only half the battle—accuracy is non-negotiable.

That’s where Human-in-the-Loop (HITL) validation plays a vital role. While the RiskSpan platform incorporates sophisticated AI guardrails, we believe the right blend of automation and expert oversight ensures results that are not just fast—but reliable, auditable, and production-ready.

The AI-Powered Workflow: What’s Automated

Our private ABF modeling and surveillance system uses LLMs to handle several critical tasks:

  • Data Extraction: Parsing offering memos, indentures, and loan tapes to extract structural and financial data.
  • Deal Code Generation: Producing executable waterfall models based on extracted rules.
  • Database Ingestion: Uploading validated deal terms and triggers into the RiskSpan system of record.
  • Surveillance Automation: Running periodic deal performance analyses and compliance checks.

But What About Hallucinations?

Generative models are powerful but imperfect. Without the right controls, they can fabricate securitization tranches or fees that are not present in the deal documents. They can also misinterpret waterfall rules or omit critical override conditions or generate semantically incorrect code for cashflow models. To address these challenges, RiskSpan employs a multi-layered safeguard framework, combining asset class based extraction; LLM-as-Judge; Rule-Based Guardrails and Inline Human Review

Humans in the Loop: Three Layers of Oversight

We’ve embedded human validation at three key points in the deal lifecycle:

  1. Pre-Modeling Validation: before LLM-generated outputs are finalized, RiskSpan analysts review extracted terms and model prompts—correcting anything misaligned with the source documents.
  2. Inline Oversight: during waterfall code generation, humans validate AI-generated logic in context, ensuring correct treatment of subordination, triggers, caps/floors and other.
  3. Post-Deployment Monitoring Surveillance: outputs are reviewed both by the RiskSpan team and client-side structuring or credit teams. Feedback is looped back into model tuning and prompt optimization.

Looking Ahead: RAG and Continuous Improvement

We’re actively exploring Retrieval-Augmented Generation (RAG) to reduce hallucinations even further. By grounding AI responses in deal-specific material such as offering documents, trustee reports, and internal risk memos—we aim to: 1) eliminate off-topic responses. 2) increase trust in model-derived outputs and 3) enable deeper customization per issuer or asset class.

The Takeaway

AI is transforming how private ABF deals are modeled and monitored—but it must be grounded and guided by human expertise and built for institutional rigor. At RiskSpan, we’re not just accelerating workflows—we’re raising the bar for accuracy and trust in AI-assisted private structures. Human-in-the-loop is not a fallback—it’s a strategic pillar.

June 2025 Models & Markets Update – Predictive Power Amid Economic Uncertainty

Register here for next month’s call: Thursday, July 17th, 2025, 1 p.m.

Each month, we host a Models & Markets call to offer our insights into recent model performance, emerging credit risks, and broader economic indicators. This month, we showcased our responsiveness to shifting macroeconomic dynamics and introduced new transparency elements (i.e., back-testing tools) to our prepayment and credit modeling.

Click here to listen to the entire 23-minute recording, or continue reading for a summary.

Agency Prepay Model: Back-testing and Enhanced Control

We are launching a new loan-level prepayment back-testing tool using nearly all agency loans (FN/FH/GN) aged 10 years or less. The tool runs every month through our models with historical home prices and interest rates. Based on this data, we have an interactive dashboard that will allow users to drill down into model performance with far more granularity than currently possible.

Key Enhancements to Prepay Model v. 3.8

A soon to be released version of the prepay model will include:

  • User-defined slope multipliers for both Out-of-the-Money (OTM) and In-the-Money (ITM) performance, offering finer control over refinance sensitivity and turnover behavior.
  • Independent knob control across CONV 30, CONV 15, FHA, and VA loan types.

A redesigned ARM prepayment framework, derived from the fixed-rate model. The new ARM component includes:

  • A realistic payment shock element that aligns prepayment spikes with rate reset events.
  • Improved seasonality and aging ramp that reflects empirical loan behavior

These updates give users the ability to more precisely tune model responses under a variety of macroeconomic and borrower scenarios.

Credit Model: V7 and Delinquency Transitions

The delinquency transition matrix incorporated into our new Credit Model V7 provides users a more nuanced credit risk assessment. This model works in conjunction with the enhanced prepayment model to better simulate the joint dynamics of default and prepay behavior across economic cycles.

Macroeconomic Context: Rates and Risk in a Holding Pattern

We remain cautious in our outlook for the remainder of 2025 and into 2026:

The Fed Funds Rate is expected to remain elevated—currently in the 4.25–4.50% range—with the first rate cut likely in September. By year-end 2025, the market expects it to settle around 3.75–4.00%.

Mortgage rates remain stubbornly high, hovering above 6.5%, putting pressure on origination volumes and reinforcing the value of accurate prepayment modeling.

Home prices and broader macro indicators like unemployment and PCE inflation remain stable, suggesting a “wait-and-see” mode for both consumers and investors.

What’s Next: More Models, More Tools, More Insights

We continue to expand our Platform with new analytics, model documentation, and client-facing tools. Users can soon access the new back-testing report directly within the Platform, alongside these updated prepayment and credit models. These developments reflect our commitment to model transparency, data-driven innovation, and practical tools for real-time market adaptation.

Private Credit Market Pulse: What LPs Want from Their Data and How to Deliver It

Limited Partners (LPs) continue to demand better data, faster, and with full transparency. At this week’s Private Credit Tech Summit in New York, I moderated a panel of industry leaders for a discussion on where LP expectations are heading and the challenges managers face trying to meet them.

My fellow panelists included:

·      Charlie Tafoya, Co-Founder and CEO of Chronograph

·      Marios Tsiptis, Senior Portfolio Manager

·      Arnab Mazumdar, Partner at Pantheon

We explored the evolving expectations of LPs, the operational hurdles General Partners (GPs) face, and the technology shaping the next frontier of data transparency in private credit.

What follows is where we landed.

LP Expectations Are Outpacing the Status Quo

Quarterly performance reports and aggregate numbers used to be enough. But Marios Tsiptis explained that today’s LPs (particularly insurance companies) want detailed, timely insight into exactly what they own and what risks they’re carrying.

From Pantheon’s fund-of-funds vantage point, Arnab Mazumdar laid out three foundational data pillars:

1.     Performance metrics

2.     Operating and credit-level data

3.     Consistency across managers

Lagging information and inconsistencies across investment structures, especially between SMAs and feeder funds, create significant friction. Structure matters, and data must be complete, accurate, and delivered on LP terms.

The Operational Reality: Bridging Ambition and Execution

Charlie Tafoya, who works closely with GPs via Chronograph, provided a sobering view of the day-to-day realities. Many managers are eager to modernize, but they’re grappling with:

·      Delays in data delivery

·      Data quality and validation issues

·      Fragmented internal processes

There’s just no getting around the fact that investment teams simply must be embedded in the data flow. Too often, front-office insights are siloed from the operations teams responsible for reporting. “The investment team is the source of truth,” Charlie noted, making their engagement essential to any successful data transformation.

Meanwhile, Arnab called for a convergence of internal monitoring and external reporting. Aligning what GPs see internally with what they share externally could yield benefits across the board—but cultural and technological hurdles remain.

Technology as Enabler, Not Panacea

Tools that support data interoperability, real-time reporting, and workflow automation are rapidly maturing. But challenges persist around integration with legacy systems and data standardization.

From the LP side, Marios painted a picture of an ideal future. Intuitive dashboards, seamless access across portfolios, and fully integrated delivery pipelines all featured prominently in this future. But the road leading there is still under construction.

According to Arnab, the next few years will hinge on industry standardization and early adopters gaining a competitive edge, while laggards risk being left behind.

Transparency builds trust—but it requires real operational change.

More than just a tech problem, this requires a cultural shift. GPs and LPs need to work as true partners in designing data ecosystems that are not only robust and scalable, but also reflect the growing sophistication of the private credit space.

As the private markets evolve, so too must the infrastructure that supports them. Those who succeed in this transition will not only meet the expectations of today’s LPs, but also shape tomorrow’s.

Design Smarter — How AI is Changing UX from Idea to Execution 

AI is revolutionizing everything, and the UX design process is no exception. From the earliest conceptual ideas all the way through to final execution, the transformation is not just about speeding up workflows but also about enhancing creativity and collaboration.  

Here’s how. 

Initial Ideation

Every UX journey begins with the ideation process. AI tools like Claude have become a go-to starting point for brainstorming and generating initial design prompts. By feeding basic requirements and user journeys into the AI, I can quickly generate a list of potential features and pain points. For example, when working on a new ETL tool, Claude helped identify potential difficulties in data mapping, handling large datasets, and ensuring data accuracy during the transformation process. These pain points helped Claude generate a list of requirements and user journeys, which were then used to create a first-pass prototype 

This initial step is crucial as it sets the foundation for the entire design process. 

Rapid Prototyping

Once the ideation phase is complete, the next step is creating a first-pass prototype. Claude has helped me here by generating quick, functional prototypes that provide a visual representation of the overall application. Although not fully functional, these prototypes nevertheless offer a solid starting point for further refinement. This rapid prototyping capability allows me to iterate quickly and incorporate feedback more efficiently. 

After the initial prototype is created, I import it into Figma for refinement. This is where the design gets polished with logos, color schemes, and other branding elements. This is a highly collaborative phase of the process, where designers work closely with developers and test users to finalize the look and feel of the application. This step ensures that the design is not only functional but also visually appealing. 

Code Development

The final stage involves turning the refined design into a working application. Here, remarkably, AI tools like Claude and Cursor (an AI-enhanced version of VS Code) can actually generate and refine the code itself. By providing the AI with an image of the final design, it can produce a close approximation of the user interface, which can then be fine-tuned by developers. For example, I might ask Claude to generate a sample layout based on the refined design and then use Cursor to make specific changes, such as adjusting font sizes and colors. This significantly reduces the time and effort required to build the front end of the application. 

Real-World Application and Testing — Collaboration and Continuous Improvement

The iterative nature of AI tools allows for rapid prototyping and testing, leading to a more efficient development cycle. While AI-generated code might not be perfect, the ability to quickly identify and fix bugs makes the process much faster than traditional methods. For instance, I used Cursor to highlight and fix errors in the code by simply providing and asking it to correct the issues. 

But collaboration remains supremely important. AI tools facilitate cross-functional teamwork by making it easier to share prototypes and gather feedback. This collaborative approach ensures that the final product meets the needs of all stakeholders. Additionally, the iterative nature of AI tools means that the design can continuously evolve based on user feedback and testing. 

—————- 

AI is not just a tool for speeding up the UX design process; it’s a catalyst for innovation and collaboration. By leveraging AI for ideation, prototyping, and code development, designers can create smarter, more efficient workflows that lead to better user experiences. The future of UX design is not just about working faster but also about working smarter. 

Using LLMs as judges for validating deal cash flow models: A new frontier in securitization modeling

As securitization models become increasingly complex and differentiated, validation becomes a critical challenge. We’ve experimented with an innovative approach that leverages large language models (LLMs) as impartial judges to validate models implemented across different platforms.

The Dual-Implementation Challenge

In cash flow modeling, we often maintain parallel implementations—typically in Python for flexibility and Excel for transparency. How do we ensure both versions produce consistent results?

Enter the “LLM as Judge” approach!

A Real-World Case Study: Residential Transition Loan Funding

Consider a portfolio of residential transition loans with a funding structure including:

  • 100 loans averaging $275,000 each
  • 12-month average terms at 8.75%
  • A 75% advance rate
  • 2% loss reserve build-up
  • Performance triggers based on delinquency rates

We implemented this structure in both Python and Excel, then submitted both models to an LLM for validation.

The LLM Validation Process

The LLM first analyzed the conceptual alignment between models, confirming both followed the same fundamental approach to cash flow projection, default assumptions, reserve mechanics, and triggers.

Next came a rigorous numerical comparison. The LLM detected a $100,000 investor distribution discrepancy in Month 2:

  • Python model: $1,790,702
  • Excel model: $1,690,702

Through logical analysis, the LLM determined this likely stemmed from differently evaluated trigger conditions. This kind of subtle implementation difference could easily go unnoticed in manual validation, potentially leading to significant valuation discrepancies over time.

Beyond Discrepancy Detection

The true power of this approach extends beyond finding differences. The LLM also provided:

  1. Stress testing recommendations tailored to our specific product, including scenarios for rapid defaults, extension waves, and interest rate shocks
  2. Model risk management insights highlighting documentation needs and suggesting a formal reconciliation process
  3. Code quality assessment noting strengths and weaknesses in both implementations

Why This Matters

For securitization professionals, this approach offers several advantages:

  • Efficiency: Automation of tedious line-by-line comparisons
  • Comprehensiveness: Identification of conceptual differences, not just numerical ones
  • Regulatory compliance: Better documentation for model risk management requirements
  • Objectivity: Unbiased third-party perspective

Mounting Pressure in Non-QM Credit: What March 2025 Data Signals for Risk Managers

This is a monthly update on non-QM delinquency rate and roll rate trends based on the March 2025 remittance data. Similar to last month’s post, I use the CoreLogic Non-Agency loan data to split out the Non-QM population by loan type. I compare the relative delinquency performance of mortgages backed by Investor properties vs. loans with full documentation vs. other Non-QM loan types (this last bucket comprises mainly Bank Statement loans). I use a slightly revised and more inclusive definition of Non-QM this month so the overall balance figures are higher and delinquency rates and roll rates are slightly lower than those reported in last month’s post.

The first chart shows that the non-performing delinquency rate (60+ dpd loans as a percentage of the overall population) has risen from a post-COVID low of 0.85% in July 2022 to 3.09% as for the most recent remit month. This increase has been driven by deterioration in the credit performance across all Non-QM loan types. Notably, the delinquency rate for Investor loans increased to 3.56% as of March, up more than three-fold from post-COVID lows of 1.1% in October 2022 and up 91bp year over year. Full Doc Non-QM loans continue to outperform other segments significantly, but their delinquency rates still rose to 0.85%, a new post COVID recovery high.

The other driver of the increase in delinquency rates for the Aggregate Non-QM loan population is a gradual shift in their mix away from the Full Doc loans, which have a better credit profile. As shown in the graph below, Full Doc loans as a percentage of the overall NQM mix have fallen from over 50% of NQM population as of the end of 2018 to only just under 31% in March. Meanwhile, Investor loans have increased from only 3% of the Non-QM population as of the end of 2018 to 10% just before COVID to over 24% as of March.

The last graph considers the gateway transition of mortgages to non-performing status: the current to 30 roll rates, or the percentage of current loans that roll to 30 days delinquent in any given month. These trends are broadly in line with what we see for the overall delinquency rates: roll rates have increased significantly since their post COVID lows.

In the March remittance data, overall Non-QM C->30 roll rates increased to 1.18%, their highest level since December 2020. All 3 non-QM segments broken out in this graph also hit new post COVID highs, with Investor-backed loans experiencing a 1.43% C->30 roll rate, 2.9x the 0.50% roll rate experienced by Full Doc Non-QM loans.

As non-QM mortgages show signs of growing distress amid broader economic uncertainty, we recommend heightened vigilance for investors and risk managers with Non-QM exposure in their portfolios. RiskSpan’s credit models forecast delinquency roll rates directly, and our modeling team calibrates our suite of models to capture both the overall trends and the differentiated performance across loan and product types. These models are just one component of our scaled analytics solutions to help our clients evaluate risk and make investment decisions.
