Big Data and Underwriting in Commercial Insurance

Insurance underwriting data is essential in assessing the risk of potential clients for commercial insurance coverage and pricing. With the emergence of big data and synthetic data, underwriters have a powerful tool to improve the accuracy of underwriting models. In this article, we will explore the benefits and challenges of these data sources and their impact on commercial insurance underwriting.

Pulling in Big Data to Insurance Underwriting

Big data refers to large volumes of structured and unstructured data that can be analyzed to reveal patterns, trends, and associations. In commercial insurance underwriting, big data can include property information, metrics on weather patterns, and other external factors that may influence risk.

In particular, the use of big data in underwriting has gained significant attention in recent years. With vast amounts of data now available on every aspect of our lives, underwriters can pull in external data sources to gain a more complete picture of each client’s risk profile. For example, underwriters can access property information such as building construction, age, and occupancy, as well as weather patterns, crime rates, and other relevant data points to better assess risk. 

These sources can be especially valuable for large or complex risks that are more difficult to evaluate with traditional methods. With the help of machine learning algorithms, underwriters can quickly analyze these data sets to identify patterns and associations that may be missed by human analysis, leading to more accurate pricing and coverage models.

However, while big data can be a powerful tool, there are several challenges that underwriters must address to ensure its effectiveness. One major challenge is the quality of the data itself. With so much information available, it can be challenging to determine which sources are reliable and relevant to a particular underwriting scenario. Additionally, data privacy regulations must be considered when accessing external data sources. Underwriters must ensure that they are not violating any laws or ethical principles when collecting and using this data.

Despite these challenges, big data can be a valuable asset to commercial insurance underwriting. By pulling in external data, underwriters can improve the accuracy and efficiency of their models, leading to more effective risk management and better outcomes for clients.

Creating Synthetic Data for Insurance Underwriting

In addition to pulling in external data, underwriters can also use synthetic data to improve models. Synthetic data refers to artificially generated data created using machine learning algorithms and statistical models. The data is designed to mimic real-world data, allowing underwriters to create more accurate and diverse models

Creating Synthetic Data

To create synthetic data, underwriters may use AI algorithms to generate data based on existing data sets. For instance, an algorithm could use customer demographic data to create synthetic data for similar customers with slightly different attributes. The synthetic data can then be used to train machine learning models to improve accuracy and diversity.

Advantages and Examples

The advantages of synthetic data include the ability to create new data sets that may not exist in real life, reduce bias and increase diversity in models, and protect the privacy of real-world customers. However, creating synthetic data poses several challenges, including ensuring the accuracy and relevance of the data and mitigating the risk of overfitting models.

To provide an example, consider an underwriter who is assessing the risk of insuring a new manufacturing plant. The underwriter may use existing data sets on similar plants to create synthetic data that simulate a wider range of potential scenarios. This could include data on factors like equipment usage, employee turnover, and supply chain disruptions. By using this synthetic data to train machine learning models, the underwriter can create more accurate and diverse models that reflect the complexity and variability of real-world manufacturing operations.

Another example is an underwriter assessing the risk of insuring a new e-commerce business. The underwriter may use existing data sets on similar businesses to create synthetic data that simulates a wider range of customer behavior patterns. This could include data on factors like browsing habits, purchase history, and social media activity. By using this synthetic data to train machine learning models, the underwriter can create more accurate and diverse models that reflect the complexities and variability of real-world e-commerce operations.

Overall, the use of synthetic data can help underwriters create more accurate and diverse models, leading to better outcomes for clients. However, underwriters must ensure that the synthetic data is relevant, and accurate, and does not introduce biases or overfitting. By carefully selecting and curating synthetic data sets, underwriters can harness the power of machine learning to improve their underwriting models and stay ahead of the competition.

Improving Insurance Underwriting Models with Data

The use of big data and synthetic data can greatly enhance the accuracy of underwriting models. One of the ways to achieve this is by identifying new risk factors that were previously overlooked. Traditional insurance underwriting methods may only consider a narrow set of variables such as claims history or credit scores to assess a client’s risk profile. However, big data provides access to a wider range of variables that can be relevant in assessing risk. For example, underwriters can use data on social media activity or online behavior patterns to evaluate the risk of insuring a particular business.

Machine Learning

Machine Learning algorithms can use this data to identify patterns and associations that may have been missed through traditional methods. For instance, an algorithm may reveal that clients in a particular industry, located in a specific region, are more prone to making certain types of claims. Machine learning algorithms can also recognize complex interactions between variables that may not be apparent through human analysis. For instance, an algorithm may indicate that clients living in areas with high levels of air pollution are more likely to experience certain health issues that could impact their risk profile.

These types of insights can help underwriters create more accurate pricing and coverage models that better reflect the unique risk factors associated with each client. In addition, the use of machine learning can also help automate parts of the underwriting process. For instance, algorithms can quickly analyze a large volume of data to identify high-risk clients, allowing underwriters to concentrate on evaluating these clients in more detail. This can help underwriters make more informed decisions and reduce the risk of overlooking important risk factors.

In summary, the use of big data and synthetic data can significantly enhance the accuracy and efficiency of underwriting models. By embracing these new data sources and utilizing machine learning, underwriters can stay ahead of the competition and provide better service to their clients.
