MBS ratings and the mortgage credit boom
We study credit ratings on subprime and Alt-A mortgage-backed-securities (MBS) deals issued between 2001 and 2007, the period leading up to the subprime crisis. The fraction of highly rated securities in each deal is decreasing in mortgage credit risk (measured either ex ante or ex post), suggesting that ratings contain useful information for investors. However, we also find evidence of significant time variation in risk-adjusted credit ratings, including a progressive decline in standards around the MBS market peak between the start of 2005 and mid-2007. Conditional on initial ratings, we ...

Good news is no news? The impact of credit rating changes on the pricing of asset-backed securities
We assess the impact of credit ratings on the pricing of structured financial products, using a sample of more than 1300 changes in Moody's or Standard and Poor's (S&P) ratings of U.S. asset-backed securities (ABS). We find that rating downgrades tend to be accompanied by negative returns and widening spreads, with the average effects stronger than those that have been reported in prior research on corporate and sovereign bond ratings. A portion of the negative implications of ABS downgrades are anticipated by price movements ahead of the rating action, although to a lesser degree than has ...

Constant proportion debt obligations: a post-mortem analysis of rating models
In its complexity and its vulnerability to market volatility, the CPDO might be viewed as the poster child for the excesses of financial engineering in the credit market. This paper examines the CPDO as a case study in model risk in the rating of complex structured products. We demonstrate that the models used by S&P and Moody's would have assigned very low probability to the spread levels realized in the investment grade corporate credit default swap market in late 2007, even though these spread levels were comparable to those of 2002. The spread levels realized in the first quarter of 2008 ...

Market declines: Is banning short selling the solution?
In response to the sharp decline in prices of financial stocks in the fall of 2008, regulators in a number of countries banned short selling of particular stocks and industries. Evidence suggests that these bans did little to stop the slide in stock prices, but significantly increased costs of liquidity. In August 2011, the U.S. market experienced a large decline when Standard and Poor?s announced a downgrade of U.S. debt. Our cross-sectional tests suggest that the decline in stock prices was not significantly driven or amplified by short selling. Short selling does not appear to be the root ...

Your credit score is a ranking, not a score
With credit scores affecting so many important aspects of our lives, it?s no wonder that people are concerned with improving their scores. Once they start to pay attention to them, though, consumers often find their scores changing in unpredictable ways. Knowing that your score is not a rating of your creditworthiness but a measure of where your creditworthiness ranks relative to everyone else is the first step in understanding your score and how to manage it.

Understanding the securitization of subprime mortgage credit
In this paper, we provide an overview of the subprime mortgage securitization process and the seven key informational frictions that arise. We discuss the ways that market participants work to minimize these frictions and speculate on how this process broke down. We continue with a complete picture of the subprime borrower and the subprime loan, discussing both predatory borrowing and predatory lending. We present the key structural features of a typical subprime securitization, document how rating agencies assign credit ratings to mortgage-backed securities, and outline how these agencies ...

The evolution and determinants of emerging market credit spreads in the 1990s
This paper develops measures of emerging market credit spreads for the 1990s, based on data on new bond issues and bank loans, that cover a broader range of borrowers than the Brady bond spreads most commonly used to date. These measures are used to identify the impacts of credit ratings, maturity and currency denomination on spreads. We find important regional differences in spreads across the developing world, even after controlling for risk and maturity. We also identify the evolution of spreads during the 1990s up until the advent of the Asian financial crisis, holding other determinants ...
