Global insurance and reinsurance broker Aon says cedents entered the Jan. 1 renewals with leverage on their side. Record capital, another profitable year for reinsurers, and a benign 2025 Atlantic hurricane season combined to create what the firm calls competitive tension across the market.
Aon will publish its full Reinsurance Market Dynamics January 2026 Renewal report next week. For now, it has shared early signals. Dynamics at 1/1 broke decisively in favour of buyers.
Capital sits at the center of the story. As of Sept. 30, 2025, global reinsurer capital reached a record $760bn, up $45bn from $715bn a year earlier.
Retained earnings drove most of the increase. According to Aon, reinsurers didn’t just earn well. They kept it.
Profitability followed. The sector posted an average annualised return on equity of 16% during the first nine months of 2025. That comfortably cleared estimated costs of equity. When capital earns that kind of spread, pricing pressure shows up fast.
The balance sheet strength came with help from the weather. A relatively calm Atlantic hurricane season limited large losses.
At the same time, third-party investors kept leaning into insurance risk. Aon says alternative reinsurance capital climbed to $124bn by the end of Q3, up $9bn year on year. Fresh money, still coming in.
Capital markets activity reinforced the trend. The catastrophe bond market closed the year at a record, with more than $24bn issued across 74 sponsors and $58bn outstanding.
Market trackers later put issuance at $25.3bn and outstanding volume at $61.1bn. Either way, it’s the same message. Demand didn’t blink.
Sidecars expanded too. Throughout 2025, new reinsurers, new investors, and new structures pushed that segment forward. The menu of capacity options kept growing. Buyers noticed.
Aon expects those capital levels to do more than cut rates.
The broker points to emerging risk protection as a next outlet, especially data centres. Investment in that sector could reach $5trn to $10trn by 2030, by Aon’s estimates, pulling in large volumes of reinsurance capacity.
Liability demand sits on a similar track. Regulatory change and litigation trends continue to widen exposure. A recent Aon study estimates emerging casualty risks could add roughly $5bn in reinsurance premium annually. Maybe more, if court outcomes keep drifting.
Competition peaked in the U.S. Buyers there leaned hard into favourable renewal conditions. Preferred risks often secured double-digit rate reductions at Jan. 1, according to the broker.
Europe and Latin America followed similar patterns, with a few carve-outs. Asia Pacific went further. Non-loss impacted accounts in the region saw rate cuts approaching 20%.
Alfonso Valera, international chief executive for reinsurance solutions at Aon, says returning buyers now face a broad array of options. Frequency covers and earnings protection are easier to place.
Interest is rising in structured solutions, loss portfolio transfers, and facultative placements, including hybrid treaty-facultative structures. Choice, for once, isn’t the constraint.
According to Beinsure analysts, the signal from 1/1 is clear enough. Capital isn’t scarce. Risk appetite has widened. Pricing power shifted, at least for now. The next test comes when losses return.
