Surety Reinsurers Absorb Large Contractor Defaults
Construction firms relying on surety bonds should expect reinsurance capacity to be priced more selectively by cedent.
Updated on Nov. 2, 2026 in Construction
US surety primary carriers continue to post direct loss ratios that remain low by historical standards, but their largest losses have grown large enough to break through primary retentions and shift volatility to reinsurers ahead of January 1 renewals. Contractors, construction project sponsors and the reinsurers that back surety writers should expect tighter terms as renewal pricing reflects this tension.
Why it matters
Primary writers have raised their retentions, and excess of loss treaties expose reinsurers to large contractor and project defaults rather than steady attritional profit. For construction businesses that rely on surety bonds, that means the capacity behind their bonding programs is being repriced and differentiated more sharply by cedent.
The Pine Gate Renewables Chapter 11 filing touched about $1.85 billion of surety bonds and surety-backed letters of credit, while Morningstar DBRS estimated the First Brands collapse could cost credit insurers $300 million to $600 million. Coface expects US insolvencies to rise around 8% this year, but the final reinsurance loss total and renewal pricing outcome remain unknown.
The players
Willis Re
The reinsurance broker whose analysis reports that US surety reinsurers are absorbing volatility as primary carriers post low direct loss ratios.
Morningstar DBRS
A credit rating agency that estimated the First Brands collapse could cost credit insurers $300 million to $600 million.
Coface
A credit insurance and trade-credit firm that expects US insolvencies to rise around 8% this year.
Pine Gate Renewables
A renewable energy developer whose November 2025 Chapter 11 filing affected around $1.85 billion of surety bonds and surety-backed letters of credit.
The details
Excess of loss treaties leave reinsurers exposed to a small number of large contractor and project defaults instead of predictable attritional losses. Many data center projects are financed through special-purpose vehicles, which often keep the tenant or sponsor behind the obligor hidden from the reinsurer. Reinsurers are therefore expected to keep supporting surety, particularly for multi-line clients, while differentiating more sharply by cedent.
Timeline
September 2025: First Brands collapse, with Morningstar DBRS estimating $300 million to $600 million of credit insurer cost.
November 2025: Pine Gate Renewables files for Chapter 11, affecting around $1.85 billion of surety bonds.
October 5, 2026: US 10-year Treasury yield reaches 5.31%.
January 1, 2027: Reinsurance renewals, where pricing and terms will reflect this tension.
Market Landscape
The September 2025 First Brands collapse, which Morningstar DBRS estimated could cost credit insurers $300 million to $600 million, sets a recent precedent for large credit losses flowing to reinsurers. The pattern now extends into surety, where the Pine Gate Renewables filing shows single defaults can break through primary retentions.
Contractors and project sponsors should expect reinsurance-backed surety capacity to be priced and placed more selectively by cedent as renewals approach. Finance and procurement teams that rely on bonding should review their surety programs and the financing structures behind large projects before the January 1 renewal season.
The takeaway
Surety reinsurance costs are being driven by a handful of large project and contractor defaults rather than routine losses, so construction firms should watch how their bonding capacity is repriced at the January 1, 2027 renewals. Track any changes in retention levels and program terms with your surety provider, and review project financing structures that could obscure the underlying obligor.
What happens next
Reinsurance treaty renewals take effect January 1, 2027, when pricing and terms for surety programs will reflect the recent large losses.
