The rating and launch of the platform come as the US surplus lines market continues to be one of the fastest-growing parts of the property-casualty sector, driven by tightening appetite in admitted markets and elevated catastrophe, liability, and social inflation pressures. Brokers have increasingly turned to E&S carriers for complex property schedules, higher-hazard casualty business, and emerging risks where standard policy forms and rate structures are less suitable. An A+ rating gives MSIG Specialty Insurance America, Inc. a stronger footing to compete for this business, particularly when brokers need to balance flexibility of form with counterparty strength requirements from insureds, lenders, and regulators.
