An analysis of blockchain in insurance

As my mentorship programme with Portagion recently concluded in July with a fireside chat, I found myself reflecting on the most impactful moments. A conversation from our March session particularly stood out - one I had with a personal hero in the actuarial world, Michael Jordan, better known as MJ The Fellow Actuary. I had the chance to ask him about the future of blockchain in insurance from an actuarial standpoint.

His response was insightful. From a technical perspective, he pointed towards the complex challenge of modeling NFT price fluctuations. But on a practical note for an aspiring actuary, his advice was clear: prioritize the qualification examinations and perhaps put the world of blockchain on a brief pause.

That advice to focus on the core curriculum resonated deeply and remains a firm priority. However, my curiosity about what feels like an inevitable technological shift in our industry persisted. This post is the result of that balancing act—my own detailed exploration into the past, present, and future of blockchain in insurance, spurred by that memorable conversation.

The Old Guard’s Dilemma: An Industry Built on Friction

The traditional insurance industry, while a vital pillar of the global economy, operates on a model burdened by deep-seated structural flaws. Heavy reliance on manual, paper-based processes and outdated legacy systems—some still running on technology from the 1980s—creates significant economic costs, operational risks, and a persistent trust deficit with customers. The industry’s very foundation is a promise, yet the processes supporting it are often characterized by opacity and friction.

This environment is plagued by a lack of a single, verifiable source of truth, making it highly susceptible to fraud. The FBI estimates that non-health insurance fraud costs the average U.S. family between $400 and $700 per year in increased premiums. This created a clear and compelling need for a new architecture—one that could engender trust not through a central authority, but through the very nature of the system itself.

Enter Blockchain: A New Architecture for Trust

The technological answer emerged with the advent of blockchain and, more importantly for insurance, the “smart contracts” it enables. These are not contracts in the legal sense, but self-executing computer programs where the terms of an agreement are written directly into code. This technological leap was the critical catalyst that made blockchain relevant to the contract-centric insurance industry.

Core Applications Across the Value Chain

After years of experimentation, a number of mature applications are now delivering tangible value:

• Claims Management & Fraud Prevention: This remains the “killer app.” A prime example is the platform used by StateFarm and USAA to automate auto subrogation claims. By using a shared ledger, they streamline the exchange of information and funds, reducing processing time and administrative overhead.
• Parametric Insurance: This model has emerged as a powerful application. The Lemonade Foundation launched a blockchain-based crop insurance product for farmers in Africa. It uses smart contracts automatically triggered by verifiable weather data from trusted sources, making microinsurance economically viable.
• Regulatory Reporting: The openIDL platform provides a secure and efficient way for U.S. insurers to submit regulatory data, reducing a significant administrative burden.

The Reality Check: Headwinds and Hard Lessons

The path to adoption is not straightforward. The industry has faced significant hurdles and high-profile failures that offer crucial lessons.

Systemic Barriers to Adoption

Beyond specific failures, the industry faces persistent headwinds:

• Regulatory & Legal: Ambiguity around the legal status of smart contracts and conflicts with data privacy laws like GDPR create significant risk and uncertainty.
• Technical & Operational: The immense cost and complexity of integrating with legacy systems, coupled with a lack of industry-wide standards and interoperability, remain the greatest practical barriers.
• Human & Cultural: A conservative, risk-averse culture, corporate inertia, and a significant shortage of talent with both insurance and blockchain expertise slow down innovation.

The Economic Equation and the Next Frontier

Despite the challenges, the economic case is compelling. An early analysis by Goldman Sachs projected that blockchain could generate $2 to $4 billion in annual cost savings in the U.S. underwriting sector alone. Market forecasts project a Compound Annual Growth Rate (CAGR) exceeding 50% through 2031.

The true long-term potential, however, lies in its convergence with Artificial Intelligence (AI) and the Internet of Things (IoT). This technological triumvirate enables a profound shift from a reactive model of loss compensation to a proactive model of risk prevention. An insurer’s value proposition moves from “we will pay you back if something bad happens” to “we will help you stop the bad thing from happening in the first place.”

Final Thoughts

The initial hype of wholesale disruption has given way to a more nuanced and sustainable evolution. The market has undergone a “great filter,” shifting from ambitious, capital-intensive projects toward disciplined solutions delivering measurable, near-term ROI. While the path to widespread adoption is still paved with the significant challenges I’ve outlined, the trajectory is clear. Blockchain is evolving from a buzzword into a foundational technology that will bring much-needed trust and efficiency to the insurance industry. The journey is just beginning.
