J. P. Morgan Asset Management has released an important fixed income strategy study by Managing Director Douglas Niemann that features Kamakura Risk Information Services default probabilities. Mr. Niemann, Managing Director of Global Insurance Solutions, demonstrates how the decline in market-making in the bond markets in recent years has created special opportunities for fixed income investors who can invest for the longer term. The key, Mr. Niemann argues, is the ability to parse the total credit spread on a bond into its pure credit component, driven by the issuer default probability and the recovery rate on the bond issue, and the liquidity component that rewards the buyer for providing long term liquidity. Kamakura Corporation research is featured prominently in the article. Mr. Niemann provides a roadmap for investors who are making the transition from qualitative credit ratings to more modern and more accurate quantitative default probabilities.
Mr. Niemann’s article “Making the Most of Interesting Times in the Bond Markets” is available on the J. P. Morgan web site. Mr. Niemann is featured in a separate video presentation as wel.
Kamakura Corporation has embedded its extensive research on the relationship between credit spreads and default risk in its risk information and risk management software products:
Martin Zorn, President and COO for Kamakura Corporation, said Monday, “We think there is tremendous opportunity for portfolio managers that adopt modern credit risk technology and incorporate the tools into their investing strategies to earn excess returns. Advising clients in that regard and providing them with the risk information and risk management software to achieve that objective is what Kamakura Corporation is all about.

Key Analytical Insights and Examples of the Relationships Between Credit Spreads and Default Probabilities
Kamakura Corporation strongly recommends that investors explore the modern quantitative research that documents the high degree of accuracy that modern default probabilities have achieved. The Kamakura Risk Information Services version 5.0 Jarrow-Chava reduced form default probability model (abbreviated KDP-jc5) makes default predictions using a sophisticated combination of financial ratios, stock price history, and macro-economic factors. The version 5.0 model was estimated over the period from 1990 to 2008, and includes the insights of the worst part of the recent credit crisis. Kamakura default probabilities are based on 1.76 million observations and more than 2000 defaults. The term structure of default is constructed by using a related series of econometric relationships estimated on this data base. KRIS covers 35,000 firms in 61 countries, updated daily.

General Background on Reduced Form Models
For a general introduction to reduced form credit models, Hilscher, Jarrow and van Deventer (2008) is a good place to begin. Hilscher and Wilson (2013) have shown that reduced form default probabilities are more accurate than legacy credit ratings by a substantial amount. Van Deventer (2012) explains the benefits and the process for replacing legacy credit ratings with reduced form default probabilities in the credit risk management process. The theoretical basis for reduced form credit models was established by Jarrow and Turnbull (1995) and extended by Jarrow (2001). Shumway (2001) was one of the first researchers to employ logistic regression to estimate reduced form default probabilities. Chava and Jarrow (2004) applied logistic regression to a monthly database of public firms. Campbell, Hilscher and Szilagyi (2008) demonstrated that the reduced form approach to default modeling was substantially more accurate than the Merton model of risky debt. Bharath and Shumway (2008), working completely independently, reached the same conclusions. A follow-on paper by Campbell, Hilscher and Szilagyi (2011) confirmed their earlier conclusions in a paper that was awarded the Markowitz Prize for best paper in the Journal of Investment Management by a judging panel that included Prof. Robert Merton.
