Welcome to The S-Curve
Now you will be able to receive the latest announcements, product updates, and our insights on the mortgage market in real time.
The name of the blog, the S-Curve, is a reflection of our logo and the central feature of our prepayment model. S-curves are seen in nature in many phenomenon, from population growth to prepayment and default models. Our first S-curve, in the early 1990s, used the arctangent function, then piece-wise linear functions, and evolved over time to be more complex and vary by FICO, loan size and LTV. This evolution encapsulates both the timeless nature of fundamental relationships and constant innovation to describe them better over time.
We hope you find the information useful and we look forward to your feedback.

Policy Perspectives - Housing Market Dynamics and Mortgage RiskThoughtsOur latest Policy Perspective written by Richard Cooperstein offers an analysis of the U.S. housing and mortgage finance markets, focusing on key trends and forward-looking risks. While housing markets are not fully efficient, they do respond to economic imbalances which create opportunities and vulnerabilities. This article explores how demographic shifts, credit access, interest rates, and climate risks shape both housing demand and supply.
Key findings include:
- Weak demand fundamentals, especially among new homeowners
- Easing supply shortages and slowing price growth
- Elevated risk of broader housing price declines amid rising recession concerns
- Notable exposure of higher-coupon mortgages and servicing rights to interest rate and credit risks
Cooperstein also assess the resilience of mortgage-related assets under current and projected conditions.
