Chubb vs 
Marsh Surety Bonds
Chubb underwrites construction, commercial, transactional and international bonds; Marsh McLennan Agency brokers those classes through specialists.
What Is Chubb?
Chubb is the marketing name for a global insurance group whose U.S. companies underwrite commercial property, casualty, cyber and financial-lines coverage, including technology-focused DigiTech ERM and small-business packages. Founders and finance teams typically work through an appointed agent, then receive a policy issued by a named Chubb-group insurer rather than by the Swiss holding company. 1,2,3
What Is Marsh?
Marsh is a global insurance broker and risk advisor. In the United States it places coverage through core Marsh teams and through Marsh McLennan Agency for many middle-market buyers, including technology, cyber, property, casualty and benefits programs. 5,6,7,8
What Are Surety Bonds?
A surety bond is a three-party agreement: a surety guarantees an obligation your business (the principal) owes to a customer or other party (the obligee) if your business defaults. It isn't insurance that pays your business for its own losses. 10,11
Key Differences in Surety Bonds
Who Stands Behind the Bond
Chubb underwrites surety itself and reports more than 140 years of writing bonds. Marsh McLennan Agency (MMA), Marsh’s middle-market subsidiary, runs a dedicated surety practice that arranges bonds rather than issuing them. 4 9
That split decides who you indemnify and who pays a claim: Chubb is the surety on its own paper, while MMA’s reviewed page does not name the surety that would issue a given bond. 4 9
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. 4 9
MMA’s commercial surety description stresses license and permit bonds nationwide, including as a substitute for letters of credit. Chubb’s commercial surety is positioned for highly rated public and private companies and lists license and permit, court, commercial contract, reclamation, customs and workers’ compensation bonds. 4 9
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. 4 9
How You Buy and What Services Sit Around Placement
Small Chubb transactional bonds can go through the Marketplace, with other products through appointed agents and brokers. MMA describes advisor-led placement with a named Surety Department Supervisor, plus indemnity negotiation, joint-venture prequalification and ownership-transfer consulting — services Chubb’s reviewed surety page does not list. 4 9
What to Confirm in Surety Bonds Quotes
- Confirm whether Chubb would be the issuing surety or whether MMA is shopping other markets, and get the surety’s legal name on the bond form. 4 9
- Match the bond class: Chubb transactional Marketplace versus MMA contract, commercial or international placement. 4 9
- Ask MMA which indemnity package and market share apply to your account; ask Chubb how the T-listing and country list apply to your obligee. 4 9
- Ask Chubb how to file a surety claim and how to verify a bond; ask MMA who handles claims once a surety is bound. 4 9
