The actuarial profession has always evolved to respond to new questions about risk. Today, some of the most important questions facing property and casualty actuaries sit at the intersection of technology, climate, economics, and public policy.

Researchers and practitioners are exploring how emerging risks, new data sources, and rapidly advancing analytical tools can improve decision-making while maintaining the rigor and professional judgment that define actuarial practice.

At the Casualty Actuarial Society (CAS), these questions are helping shape a growing research agenda focused on advancing actuarial knowledge and supporting the profession's response to an increasingly complex world. Three areas are emerging as important research frontiers.

1. Climate Risk and the Future of Catastrophe Modeling

Climate-related risks continue to challenge long-standing assumptions about how insurers assess and manage exposure. As extreme weather events affect communities around the world, researchers are examining how changing environmental conditions may influence future losses and what those changes mean for pricing, reserving, capital management, and risk assessment.

Recent CAS-supported research has explored climate change topics involving flood risk, wildfire mitigation, and typhoon activity. These projects seek to answer practical questions that matter to insurers and policymakers alike. How can catastrophe models better reflect changing conditions? How should mitigation efforts be measured and incorporated into insurance decisions? What role should climate-informed assumptions play when historical experience may no longer tell the full story?

These challenges require collaboration across disciplines, bringing together actuarial science, climate science, engineering, and risk management to better understand the risks of tomorrow.

2. Artificial Intelligence, New Data Sources, and Actuarial Practice

Artificial intelligence is rapidly expanding the tools available to actuaries. From predictive modeling and claims analysis to decision support and operational efficiency, AI has the potential to enhance how risk is analyzed and communicated.

At the same time, new technologies raise important questions about transparency, governance, validation, and professional judgment.

CAS research and educational initiatives are helping practitioners navigate this rapidly changing environment. The recently updated second edition of the CAS AI Primer examines the opportunities and challenges associated with AI in actuarial work. Ongoing research is also exploring how large language models can be applied to unstructured claims data, a potentially valuable source of information that has historically been difficult to analyze at scale.

As AI capabilities continue to evolve, actuarial research will play an important role in identifying where these tools create value, where caution is warranted, and how innovation can be balanced with accountability and trust.

3. Understanding Emerging Sources of Uncertainty

Some of the most challenging risks facing insurers today do not fit neatly into traditional actuarial frameworks.

Social inflation, litigation trends, economic uncertainty, and increasingly interconnected risks are creating new questions about how losses develop and how risk should be measured. Addressing these challenges requires both new analytical approaches and access to new forms of data.

To support this work, the CAS has expanded investments in research infrastructure and data resources, including datasets that help researchers study litigation outcomes, catastrophe exposures, and other drivers of insurance risk. CAS working groups across ratemaking, reserving, reinsurance, and enterprise risk management continue to explore emerging questions that affect insurers, regulators, and consumers.

The goal is not simply to produce more research. It is to improve the profession's ability to understand uncertainty in an environment where risks are increasingly complex, connected, and dynamic.

Looking Ahead

While the topics differ, these three research frontiers share a common theme: understanding risk in a world where traditional assumptions are increasingly being tested.

Through research, professional education, publications, and collaboration, the CAS helps connect academic inquiry with real-world application, advancing actuarial science while equipping practitioners to address emerging challenges.

Conferences such as the Actuarial Research Conference play an important role in that effort. By bringing together researchers, practitioners, and students, they create opportunities to challenge assumptions, explore new ideas, and shape the future of the profession.

As property and casualty risks grow more complex, the future will be shaped not only by better models, but by the collective efforts of researchers and practitioners to challenge assumptions, explore new approaches, and deepen our understanding of risk.
