Trillia study shows potential car insurance savings for low-risk drivers

A study by Trillia, a B3 business line focused on Data and Artificial Intelligence, suggests that low-risk drivers in Brazil could see significant reductions in car insurance premiums. Using the AutoScore Sinistralidade platform, which analyzed data from over five million policyholders across two of the country's five largest insurers, the study found that insurance costs could drop by as much as R$ 912.

In one analyzed scenario, a policy costing R$ 2,850 could be reduced to R$ 1,938 for customer groups whose loss ratio (sinistralidade) is 33.8% below the portfolio average. The methodology segments clients into five distinct risk tiers by combining internal insurer data—such as income and assets—with external factors like location, lifestyle patterns, and theft records.

Mauricio Teramoto, Data Director at Trillia, stated that current insurance pricing often fails to reflect actual risk. He noted that the AutoScore tool aims to correct this distortion by aligning prices with effective risk, providing more equitable decisions for both insurers and clients.
