# Chubb vs Marsh Surety Bonds

Chubb underwrites construction, commercial, transactional and international bonds; Marsh McLennan Agency brokers those classes through specialists.

## Research Scope and Use

Use this comparison to evaluate Chubb and Marsh for Surety Bonds against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote.

## Summary

Chubb is the surety on the bond and publishes a $2.289 billion Treasury listing. Marsh McLennan Agency places contract, commercial and international bonds with markets it says write most U.S. contract bonds, without naming the issuer.

## 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.

## 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.

## 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](https://content.naic.org/glossary-insurance-terms "Glossary of Insurance Terms") [11](https://www.sba.gov/funding-programs/surety-bonds "Surety bonds")

## 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](https://www.chubb.com/us-en/surety.html "Surety Bonds") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk")

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](https://www.chubb.com/us-en/surety.html "Surety Bonds") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk")

### 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](https://www.chubb.com/us-en/surety.html "Surety Bonds") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk")

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](https://www.chubb.com/us-en/surety.html "Surety Bonds") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk")

### 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](https://www.chubb.com/us-en/surety.html "Surety Bonds") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk")

### 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](https://www.chubb.com/us-en/surety.html "Surety Bonds") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk")

## 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](https://www.chubb.com/us-en/surety.html "Surety Bonds") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk")
- Match the bond class: Chubb transactional Marketplace versus MMA contract, commercial or international placement. [4](https://www.chubb.com/us-en/surety.html "Surety Bonds") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk")
- 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](https://www.chubb.com/us-en/surety.html "Surety Bonds") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk")
- 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](https://www.chubb.com/us-en/surety.html "Surety Bonds") [9](https://www.marshmma.com/us/solutions/surety.html "Surety Bonds to Mitigate Company Risk")
