Using primary market transaction records from January 1999 to March 2021, the study shows that machine learning delivers higher pricing accuracy than traditional linear regression approaches. The results clarify how risk factors jointly shape bond prices in nonlinear ways, supporting more effective decision-making for both investors and issuers.

By integrating advanced machine learning techniques, our approach uncovers nonlinear relationships and complex interactions between key risk factors and CAT bond spreads—dynamics that are often overlooked by traditional linear regression models. Using primary market CAT bond transaction records between January 1999 and March 2021, our findings demonstrate that machine learning models not only enhance the accuracy of CAT bond pricing but also provide a deeper understanding of how various risk factors interact and influence bond prices in a nonlinear way. These findings suggest that investors and issuers can benefit from incorporating machine learning to better capture the intricate interplay between risk factors when pricing CAT bonds. The results also highlight the potential for machine learning models to refine our understanding of asset pricing in markets characterized by complex risk structures.  \n∗We extend our gratitude for the valuable feedback received during various academic events, including the 2023 China International Conference on Insurance and Risk Management, the Actuarial Research Conference 2023, the 2023 INFORMS Annual Meeting, as well as from the engaging seminars held at the University of Connecticut, University of Waterloo, University of Science and Technology of China, and Nankai University.

These instruments provide a valuable source of capital for issuers, helping them mitigate potentially devastating financial losses, while offering investors an opportunity to diversify their portfolios. Understanding how CAT bond prices are determined hence is essential for both investors, who seek to make informed decisions, and issuers, who aim to optimize their risk management strategies. However, accurately pricing CAT bonds is a challenging task, as prices are influenced by a wide array of factors, including bond-specific characteristics and prevailing market conditions. This paper adoptsa machine-learning-based approach to explore the complex relationships driving CAT bond prices, with a focus on uncovering potential nonlinear impacts and interaction effects among key risk factors. By shedding light on these intricate dynamics, the study contributes to a deeper understanding of asset pricing in the context of CAT bonds.  \nEarly research by Lane (2000), which introduced a log-linear regression model, laid the foundation for the CAT bond pricing literature. Lane identified two key determinants of CAT bond prices in the primary market: the probability of first loss—the likelihood that the bond will experience any loss of principal due to a triggering event—and the conditional expe","cbCaivebVn0WgIq5","https://ap.wps.com/l/cbCaivebVn0WgIq5","pdf",1117055,1,43,"English","en",105,"# Introduction\n## Research motivation and background\n## Limitations of linear pricing models\n## Related approaches and literature overview","[{\"question\":\"What problem does the paper address in CAT bond pricing?\",\"answer\":\"It investigates how CAT bond prices are determined and why traditional linear regression models may miss nonlinear effects and interactions among risk factors.\"},{\"question\":\"What data does the study use?\",\"answer\":\"The study uses primary market CAT bond transaction records from January 1999 to March 2021.\"},{\"question\":\"How do machine learning models change the understanding of risk factors?\",\"answer\":\"Machine learning reveals nonlinear relationships and interaction effects, providing a deeper explanation of how multiple risk factors jointly influence CAT bond spreads and prices.\"}]","Unveiling Nonlinear Dynamics in Catastrophe Bond Pricing -
