Underwriting 2.0: The Transition to Intelligent Underwriting

In the insurance sector, traditional manual underwriting has long been associated with mountains of paperwork—physical and digital—and extensive back-and-forth communication between clients and agents. Underwriters spend significant time entering, verifying, and rechecking submitted information. On top of that, assessing a client’s risk profile to determine policy eligibility and conditions remains a labor-intensive and time-consuming task.

A survey by Capgemini examined the time underwriters dedicate to routine administrative duties. The results revealed that nearly half (41%-43%) of underwriters spend almost a third of their time on such tasks. Also, a quarter (25%-26%) reported that their working hours are consumed by activities involving agent/broker collaboration and sales.

Despite these efforts, manual underwriting often results in human errors, operational inefficiencies, and rising costs due to the excessive use of skilled professionals for non-strategic work. Instead of leveraging automation to optimize underwriting expertise, insurers continue to struggle with outdated processes.

However, the rapid advancement of artificial intelligence (AI) and machine learning (ML) suggests that traditional underwriting may soon become obsolete. According to the Conning Survey, 77% of insurers are in some stage of adopting AI in their value chain, and at least half believe AI and ML will be essential for the industry’s future.

This shift is understandable considering the advantages of intelligent underwriting. AI-driven algorithms allow underwriters to analyze risks more effectively, enhance pricing accuracy, and accelerate application processing. With ML and deep learning, underwriting timelines shrink from days or hours to mere minutes as most processes become automated and data-driven.

New technology enables underwriters to focus more on building and strengthening relationships in the field, often serving as the primary link between their company and the marketplace.

Predictive underwriting offers substantial benefits, but how does machine learning enhance the insurance underwriting process? Let’s find out.

Machine Learning in Insurance Underwriting: Key Use Cases

Here are some common use cases of machine learning in insurance underwriting:

I. Automating Submission Triage

One of the most important applications of machine learning in insurance underwriting is automating submission triage. This involves utilizing AI-driven algorithms to efficiently sort and allocate applications to underwriters based on predefined criteria. By integrating predictive underwriting, insurers streamline workflows, ensuring that submissions are prioritized appropriately and processed more swiftly.

For instance, an ML-enhanced underwriting system categorizes applications according to their complexity and assigns them to underwriters with the necessary expertise. Another practical application involves prioritizing submissions based on the type of insurance coverage—life, health, travel, or property insurance—and directing them to specialists with the most relevant experience.

II. Optimizing Submission Processing

Reviewing large volumes of documents under tight deadlines is inefficient and error-prone when done manually. Machine learning (ML) and artificial intelligence (AI) streamline this process by automatically extracting data from PDFs, handwritten documents, and emails. Technologies like optical character recognition (OCR) and natural language processing (NLP) help insurers quickly search, retrieve, and process critical information. With ML in the insurance industry, underwriters save time and improve efficiency by automating data entry, ensuring smoother submissions.

III. Enhancing Risk Assessment Accuracy

After a submission is received, assessing its risks is crucial. ML-powered systems help by evaluating risks more accurately. Instead of relying solely on applicant-provided data, which may have errors or omissions, machine learning provides access to broader data sources like social media, banking records, and public reports. This results in a more thorough risk analysis. AI-driven systems use text classification to compare data against industry benchmarks, enhancing accuracy and operational efficiency.

IV. Refining Premium Pricing

Every risk assessment in underwriting concludes with determining the coverage amount and the premium an insurer is willing to offer—assuming they choose to provide coverage at all. Interestingly, a study highlights a case where a small business owner sought commercial insurance and received vastly different coverage quotes. Upon comparison, the premiums varied by USD 500.

Setting the right premiums in the insurance industry is no easy task. Traditionally, insurers have relied on the “cost-plus” method, which calculates risk-based pricing by factoring in direct and indirect costs and a profit margin. While this approach is functional, it has notable limitations. It fails to incorporate external pricing influences and cannot adapt swiftly to market fluctuations. When premium pricing does not align with prevailing market conditions—whether set too high or too low—the outcome remains the same: increased underwriting costs, reduced revenue, and shrinking profit margins.

Now, imagine integrating AI and ML-driven insights into underwriting analysis. Identifying optimal pricing structures in this scenario involves leveraging a far wider range of data sources, such as:

• Geospatial Information Systems (GIS)
• Predicted real estate market trends
• Geopolitical risk factors
• Climate and weather forecasting
• Real-time insights from IoT networks
• Social media analytics
• Other proprietary data sources available to insurers

Beyond achieving fairer premium pricing, insurers provide more customized quotes to policyholders. Today’s advanced AI and ML underwriting solutions adjust premiums based on individual user behavior and specific variables, such as kilometers driven or cargo transported. This shift toward AI-powered pricing models enables a more personalized and customer-centric approach to risk-based premium calculations.

Dynamic Policy Pricing: Traditional vs Intelligent

V. Enhancing Coverage Recommendations

In the insurance sector, the underwriting process concludes with presenting the applicant with the most suitable coverage option. AI and ML technologies are crucial in refining this step. Based on industry insights, ML-powered recommendation engines assist insurers in making informed coverage decisions. By analyzing historical insurance data and past underwriting submissions, these intelligent systems determine the most appropriate coverage for each applicant, including specific limits and deductibles tailored to their unique case.

This approach results in a more customized offering that aligns with the applicant’s needs and risk profile, ultimately boosting conversion rates and fostering long-term customer loyalty.

The Transformative Impact of Machine Learning in the Insurance Industry

Here’s how machine learning in insurance transforms underwriting and other processes:
