Effective tariff rates on construction goods hit a 40-year high of 25–30% in 2025, with steel and aluminum as high as 50%. Policies written on last year’s values are already underinsured.

• Deloitte’s 2026 E&C outlook is the source tape brokers are using in renewal meetings.
• Labor gaps plus material inflation push completed-value calculations through the year.
• More capacity entered builders risk, which is why non-CAT pricing loosened even as values rose.

Analyst note — Underinsurance is a claims event waiting. Sompo construction underwriters should be forcing mid-term value endorsements, not waiting for the next bound layer.

Ground-up non-CAT builders risk is stable to softening (−5% to +10%). Primary OCIP/CCIP is orderly; umbrella and excess liability still prints +5% to +30% depending on account and attachment.

• Gallagher has reported single-layer builders-risk decreases of 5–7% in non-CAT zones.
• Inland marine stays competitive even for contractors with some adverse loss history.
• CAT-exposed and high-hazard projects do not get the same relief.

Analyst note — Sompo can be relevant on non-CAT builders risk and wrap primary. The money — and the differentiation — is still in excess casualty, delay-in-start, and CAT-adjacent project property.

AXA XL’s construction property desk called 2025 a softer turning point after years of hardening: more flexibility, more capacity, more openness to complex projects — and stricter underwriting where climate CAT is real.

• ABC estimated ~439k net new construction hires in 2025 and ~499k in 2026 if spending accelerates.
• Cost inflation in labor, materials, and supply chain is still pushing insured values up.
• 2026 outlook: steadier pricing plus proactive risk mitigation, not a race to the bottom.

Analyst note — Competitors are leaning in on complex non-CAT work. Sompo’s construction franchise, now including Aspen’s U.K. property & construction specialty, should be on those same accounts.
