Marsh vs USI Insurance Services Surety Bonds

Marsh McLennan Agency (MMA), Marsh's middle-market subsidiary, arranges surety bonds through a dedicated surety practice rather than underwriting them itself. ⁵Company-reported. MMA surety insurance page.

USI is a surety bond broker, not a surety. It says it is one of the leading domestic and international surety brokers and negotiates bonding capacity and terms with surety underwriters on a client's behalf. ⁹Company-reported. Surety Bond practice page.

The reviewed page does not name a specific surety insurer for a standard bond; MMA says it offers national market representation, implying the issuing surety varies by placement. ⁵Not publicly disclosed. MMA surety insurance page as read on 2026-09-23.

MMA surety insurance page; company-reported statistics, not independently verified, and do not indicate bond size or capacity for an individual client.

USI does not publish standard bonding-capacity figures; it cites individual case studies (a general contractor's bonding limits supporting a $10,000,000 revenue increase, and a mechanical contractor whose surety line supported $110,000,000 in revenue) rather than a general limit range. ⁹Not publicly disclosed. Case-study figures on the page are specific to those named accounts, not a published capacity table.

MMA lists competitive indemnity package negotiation, industry benchmarking, joint-venture and teaming-agreement prequalification support, continuity and ownership-transfer consulting, and competitive program design review as services tied to its surety practice. ⁵Company-reported. MMA surety insurance page, Benefits of Surety and Surety Coverage sections.
