Overview
Chubb is a Swiss-incorporated global insurer spanning North American commercial, personal and agricultural P&C, overseas general insurance, reinsurance and life insurance. Q1 2026 consolidated net premiums written were $14.0B and the P&C combined ratio was 84.0%. The strongest supported moats are risk engineering and claims execution in commercial lines, HNW personal-lines reputation, a broad licensed network for locally admitted multinational programs, and controlled life-distribution channels in Asia. Nonexclusive broker relationships are not distribution control, federal crop compliance is table stakes, general analytics do not prove reinsurance operating superiority, capital strength does not by itself establish a cost-of-capital edge, and an in-force life book is not an installed-base consumables moat; those claims are removed. Catastrophe, reserve, regulatory and underwriting-cycle risks remain central.
