What was the aggregate change in US commercial property insurance rates and how did shared versus single carrier programs compare in mid-2026?
US commercial property insurance rates fell an average of 14.9% in the second quarter of 2026, according to Aon's third quarter report. Shared and layered accounts saw steeper declines at 18.7%, while single carrier programs posted more modest rate reductions of 7.5%, reflecting stronger capacity and heightened competition among underwriters pursuing well-structured property risks.
This divergence between account types reveals a telling shift in the insurance market. Shared and layered programs—where risk is distributed across multiple carriers—benefited from aggressive pricing competition as insurers competed for premium volume. Single carrier programs, by contrast, preserved pricing discipline, suggesting that carriers with concentrated exposure were more cautious about margin compression.
The backdrop to these rate movements is crucial context. According to Verisk and the American Property Casualty Insurance Association (APCIA), property casualty insurers recorded a $31.7 billion underwriting gain in the first half of 2026, nearly tripling the $11.6 billion posted in the same period of 2025. This surge in profitability has fueled carrier appetite to write new business, explaining the aggressive downward pressure on rates across the industry.
As Jack Andrew Estes explores in the episode, these insurance dynamics are part of a broader commercial real estate environment where lenders are emphasizing verified rent rolls, realistic operating expenses, tenant credit quality, and defensible exit assumptions. Cleaner property data and stronger fundamentals are enabling better underwriting across all parties.
The stronger financial position of insurers—with policyholder surplus reaching $1.3 trillion in mid-2026, up from $1.13 trillion a year earlier—provides additional cushion for rate flexibility. Yet the variance between shared and single carrier strategies indicates that capacity alone does not drive pricing. Competitive structure, risk appetite, and individual carrier profitability targets all matter.
The episode also delves into how AI and better data systems are transforming underwriting decisions across the real estate ecosystem, which directly influences how insurers price commercial property risk.
