Aon Says Record Reinsurance Capital Creates Growth Opportunities

Record global reinsurance capital and increasing competition among capital providers are creating opportunities for insurers to use risk transfer more strategically as they prepare for January renewals, according to Aon plc.

Aon's Snapshot Guide to the Reinsurance Renewal reported that global reinsurance capital reached a record $800 billion as of June 30, 2026, including a record $144.5 billion of alternative capital. Growing risk transfer capacity across multiple lines has increased competition and given buyers access to more flexible structures, broader coverage, and new solutions.

The expanded capacity comes as insurers contend with rising loss volatility, greater concentrations of exposure, and emerging risks involving casualty catastrophe, artificial intelligence and cyber, data centers, supply chains, and climate extremes.

Aon identified three priorities for insurers approaching January renewals: using capital more creatively to support growth, aligning risk with capital and product strategies, and accelerating performance through faster and more informed decisions. The firm said product value, capital relief, and access to third-party capital are becoming increasingly important as market conditions change.

"The January reinsurance renewals represent an opportunity for insurers to think differently about how they deploy capital," Steve Hofmann, CEO of the Americas for reinsurance solutions at Aon, said. "In a competitive marketplace, the conversation is increasingly about flexibility, structure, and long-term value creation, rather than price alone."

Property market conditions continued to become more favorable for buyers during 2026, with double-digit pricing reductions and increased flexibility in terms and conditions across most placements. Conditions were particularly favorable for US risks, although Aon reported ample capacity and fewer constraints in most regions.

Casualty conditions also improved, supported by strong reinsurer appetite, increased participation from third-party capital, and a broader selection of structured solutions. Aon described the casualty market ahead of January renewals as broadly stable, with terms and conditions gradually improving during 2026.

"Today's reinsurance market gives insurers more options than they have had in years," Alfonso Valera, CEO of international for reinsurance solutions at Aon, said. "The opportunity now is to use that flexibility strategically, balancing growth ambitions with risk appetites while building resilience over the long term."

Traditional reinsurers, meanwhile, remain on track for a fourth consecutive year of strong results despite increased competition among capital providers. Aon attributed the performance to profitable property and casualty reinsurance underwriting, lower ceded losses, and strong investment income. Global insured catastrophe losses during the first half of 2026 were the lowest since 2019.

The average combined ratio among 19 global reinsurers improved to 85.4 percent in the first half of 2026 from 94.8 percent during the same period in 2025. Ordinary investment returns averaged an annualized 4 percent, while reinvestment rates remained above book yields.

Return on equity averaged an annualized 15.5 percent among 31 global reinsurers during the first half of 2026 and remained above the cost of equity.

"As insurers seek to optimize capital deployment and risk transfer structures, analytics is increasingly becoming the foundation for informed strategic decision-making," George Attard, chief strategy officer and global head of analytics for reinsurance solutions at Aon, said. "Data-driven insights can help organizations better understand portfolio impacts, evaluate future risks and make more confident underwriting, portfolio management, and capital allocation decisions."
