AM Best launches online BCAR platform for P&C capital analysis

AM Best moved its Best’s Capital Adequacy Ratio Model - P/C, US onto an online platform on June 26, giving carriers a more accessible way to work with one of the industry’s most closely watched capital tools. The update pairs a user-friendly interface with a concise layout, but the more important change sits under the hood: users can now bring terrorism, natural catastrophe, and surety stress scenarios into a record and expand the factors used in the base score for B5 Mortgage and terrorism and surety in B8 charges to required capital.

That matters because BCAR is not just a rating concept. AM Best describes it as the quantitative relationship between an insurer’s balance sheet and its operating risks, and the model is designed to use the same methodology AM Best analysts apply when they assess the combined impact of financial risks under adverse market conditions. In practice, that gives finance, risk, and product teams a common language for capital adequacy, whether they are reviewing a projected year-end position, a pro forma transaction, or the capital needed to support a future business plan.

AM Best said the enhancements came in response to customer requests, a telling detail for a product that has long lived at the intersection of ratings, capital management, and planning. Adriana Franco, AM Best’s vice president of product strategy, framed the changes as an important step in the BCAR Model’s evolution, bringing new features and convenience back to users who asked for them. That is the kind of product move carriers notice: not a rebrand, but a shift toward faster modeling workflows and easier scenario handling inside a tool that already influences external rating conversations.

The company’s own methodology notes that analysts may use BCAR sensitivity calculations to quantify capital needs against business plans and transaction structures, which makes the online format more than a cosmetic refresh. For P&C insurers, the combination of a cleaner interface, broader scenario inputs, and expanded charge factors could make BCAR easier to use alongside internal planning models, reinsurance discussions, and board-level capital reviews. AM Best, founded in 1899, says it is the world’s first credit rating agency, the largest one specializing in insurance, and a business with operations in more than 100 countries. This release shows that even a legacy ratings institution now expects its core analytical product to behave more like modern software: accessible, configurable, and ready for day-to-day decision-making.
