Asian insurers secured double-digit rate reductions at the April 1 renewals, as record reinsurer capital tilted pricing power toward buyers across the region's largest reinsurance renewals, according to a report from Aon.
Global reinsurer capital reached a record $785 billion at year-end 2025, a nearly 10% increase from the prior year, the broker said in its Reinsurance Market Dynamics report.
Third-party capital climbed to $136 billion, an 18% rise driven by sustained investor appetite, while sidecar capacity grew by more than $5 billion and first-quarter 2026 catastrophe bond issuance is on track to reach approximately $6.1 billion.
The April 1 renewals serve as the primary reinsurance renewals period for Japan, South Korea, India and China, markets that collectively account for a growing share of global cession volume. Aon said demand across these markets rose roughly 10%, with cedants adding limits and restructuring programs to capitalize on favorable conditions.
Japanese property catastrophe excess-of-loss pricing fell 15% to 18%, with proportional commissions rising 3% to 5%. South Korea saw cat excess-of-loss reductions of 10% to 20%, while Greater China posted 20% cat pricing declines alongside about 5% demand growth tied to green energy, electric vehicles and data centers. In India, property cat pricing dropped 15% to 20%.
The sector's average combined ratio fell to 88.5% in 2025 from 90.1% a year earlier, a third consecutive year of results in that range. Average return on equity across 29 insurers and reinsurers tracked by Aon stood at 17%, roughly double the estimated cost of equity.
Global natural catastrophe insured losses totaled $127 billion in 2025, with California wildfires and US severe convective storms as leading drivers, though Asia-Pacific insured losses came in 54% below 21st century averages.
“In this environment, reinsurance provides insurers with powerful tools to manage volatility, protect profitability and invest confidently in new lines of business, geographies and emerging risks, as well as pursuing inorganic growth opportunities – a key trend highlighted in our report. Such actions will help insurers outperform peers as the market cycle evolves,” Aon’s Reinsurance Solutions global head of analytics George Attard said.
Aon identified cycle management as a central concern for reinsurer leadership teams. The broker said insurer margins could face pressure over the next 12 to 18 months as primary rate decreases erode earnings, though 2026 reinsurance renewals results are expected to hold absent major losses.
Separately, Fitch Ratings has maintained a "deteriorating" sector outlook for global reinsurance, noting that record-high capital supply from traditional and alternative sources outpaced incremental demand from cedants.
The agency said heightened pricing competition has been accompanied by easing terms and conditions, with reinsurers more willing to provide protection at lower attachment points. Fitch expects combined ratios and return on equity to weaken slightly in 2026, assuming major losses stay within budgets.
The April 1 renewals also reflected broader geopolitical undercurrents. Tensions in the Middle East are prompting reassessment of marine, aviation, cyber and trade credit exposures, while Aon expects mergers and acquisitions activity to accelerate as reinsurers deploy surplus capital, with Japanese and Korean insurers pursuing overseas expansion.
