What this means for contractors

Concentration favours strong files. With a handful of carriers writing most bonds, underwriting standards are consistent. Clean financials, work-in-progress schedules and a track record matter more than which carrier you approach.

Specialists fill the gaps. Regional and specialist carriers such as Merchants Bonding often suit smaller contractors and license and permit bonds. For a global view, see our top surety bond companies worldwide.

Know the cost drivers. Premiums depend on bond type, amount and the applicant's credit. See how much surety bonds cost in the US, and our support for performance bonds and advance payment guarantees and bid bonds for tenders.
