What Are the Key Differences Between Chubb and Marsh Surety Bonds?
Online Transactional Route Versus Specialist Placement
Chubb lists construction, commercial, transactional and international surety, with an online marketplace for transactional bonds. Marsh MMA runs a dedicated surety practice for contract, commercial and international bond placements, so buyers work through a specialist. 1 2 Choose Chubb if you need a transactional bond through its online marketplace; choose Marsh MMA if you need a specialist to arrange contract, commercial or international bonds.
Construction, Commercial, International — and Transactional
Both describe construction (contract) surety, commercial surety and international surety. Chubb also sells Transactional Surety Bonds for small or infrequent needs, including an online Surety Marketplace; MMA’s coverage list does not describe a transactional marketplace product. 1 2
Capacity Figures Versus Practice Scale
Chubb publishes a $2.289 billion aggregate Treasury (T-listing) as of August 2026 and says it has surety capabilities in more than 45 countries. MMA reports more than 150 surety professionals in all 50 states, $353 million in surety premium for nearly 10,000 clients, and markets that it says write 95% of U.S. contract bonds — figures about placement volume, not Chubb-style Treasury capacity. 1 2
