US Lawmakers Launch Probe into Key Insurance Rating Firm in Florida

Bloomberg reporter Leslie Kaufman cited Columbia Business School research in an article examining a congressional inquiry opened by three U.S. senators into Demotech, a key insurance rating firm for Florida insurers. The piece references data from a 2023 CBS study co-authored by Pari Sastry, which analyzed Demotech-rated insurers and highlighted vulnerabilities linked to climate-driven losses. Drawing on findings from When Insurers Exit: Climate Losses, Fragile Insurers, and Mortgage Markets, the article underscores how insurer instability can ripple through housing and mortgage markets—raising concerns for homeowners, lenders, and regulators as climate risks intensify.
