Record Capital Tests Global Reinsurance Market Discipline

The global reinsurance market is entering a critical period as record capital and increasing competition put pressure on pricing, according to AM Best's report, "Global Reinsurance at an Inflection Point: Can Discipline Survive the Temptation of Record Capital?" The next 12 months could indicate whether the discipline established during the recent hard market represents a structural change or another stage in the traditional underwriting cycle.

Reinsurers are approaching 2027 from a position of financial strength after several years of improved underwriting conditions, higher investment yields, disciplined capital deployment, and generally favorable catastrophe experience relative to pricing assumptions, per the report. Dedicated reinsurance capital is projected to reach $705 billion in 2026, including $575 billion in traditional capital and $130 billion in third-party capital.

Among US and Bermuda reinsurers, combined ratios have improved from an underwriting loss position in 2020 to the mid-80s to low-90s range following the 2023 market reset, according to AM Best. Return on equity rebounded from approximately negative 3 percent in 2022 to about 23 percent in 2023 and has since remained in the mid-to-high teens.

European reinsurers have followed a similar pattern, although their results are not strictly comparable because they report under IFRS 17, per the report. Combined ratios among the European "Big Four" declined from above 100 in 2020 to the mid-80s following the market reset, while return on equity recovered into the high teens.

Property Reinsurance Pricing Declines

Property catastrophe reinsurance is facing its first major test since the 2023 market reset, according to the report. Since that reset, reinsurers have benefited from higher attachment points, tighter terms and conditions, reduced aggregate exposures, and pricing that more closely reflects underlying risk.

Risk-adjusted property catastrophe rates declined by approximately 10–20 percent during January 1, 2026, renewals, according to AM Best. Reductions intensified during the April and midyear renewals, when US property catastrophe placements, led by Florida, experienced estimated decreases of 15–20 percent. However, the higher attachment points and tighter terms established in 2023 generally remained intact.

Most market participants continue to view current pricing as sufficient to produce adequate risk-adjusted returns, per the report. Reinsurers nevertheless have substantial capital and relatively few areas in which additional capacity can be deployed with acceptable risk-return trade-offs.

Unlike previous hard markets, recent capital growth has occurred primarily within existing reinsurers rather than through an influx of newly formed organizations pursuing market share, according to AM Best. Many large reinsurers also operate diversified platforms that include primary insurance, specialty underwriting, alternative capital operations, and managing general agent investments, providing additional options for deploying capital.

These alternatives could reduce pressure to direct excess capacity solely toward property catastrophe reinsurance, per the report. However, if competitive forces outweigh those options and pricing falls below adequate risk-adjusted levels, the market could return to a traditional soft-market cycle.

Casualty Reinsurance Draws Scrutiny

Casualty reinsurance has become one of the industry's most closely watched areas because of uncertainty surrounding pricing adequacy, reserve development, social inflation, litigation funding, larger jury awards, and long-tail liabilities, according to the report. Casualty losses can develop over many years, making it difficult to determine whether current rate increases are keeping pace with loss-cost trends.

Reinsurers are taking different approaches to casualty business, per AM Best. Some are pursuing growth opportunities at enhanced rates to increase premium and revenue, while others are tightening underwriting standards, repositioning portfolios, or strengthening reserves.

"Casualty exposures often develop over many years, meaning that decisions being made today may not be fully understood until well into the next decade," said Dan Hofmeister, director at AM Best. "Consequently, maintaining pricing discipline in casualty business may ultimately prove as important as preserving discipline within the property catastrophe market."

Investor interest in casualty insurance-linked securities is also increasing, although casualty insurance-linked securities remain a relatively small part of the alternative capital market, according to the report. Casualty liabilities can take years to emerge and are sensitive to changing legal, social, and investment conditions, creating uncertainty around ultimate losses and investment returns.

Technology and External Risks

Reinsurers are evaluating uses of artificial intelligence in document processing, claims administration, workflow automation, risk assessment, portfolio monitoring, and underwriting support, per the report. Adoption also presents challenges involving limited and inconsistent data, model explainability, regulatory compliance, governance, cyber exposure, systemic risk, bias, talent constraints, and supplier dependence.

Life reinsurance continues to provide relatively stable earnings that can help offset volatility elsewhere in large global reinsurers' portfolios, according to AM Best. The segment has benefited from interest-rate conditions and demand for longevity, mortality, health, critical illness, and capital management solutions.

Macroeconomic and geopolitical conditions could affect reinsurance loss costs, investment returns, and competitive discipline as the market approaches 2027, per the report. Renewed inflation could weaken reserve adequacy and increase claim costs, while geopolitical instability could affect property, marine, aviation, political risk, and cyber coverage.

AM Best Maintains Stable Outlook

AM Best revised its outlook for the global non-life reinsurance segment from positive to stable at the beginning of 2026, according to the report. The change reflected the market's movement into a more stable stage of the cycle, although the segment continues to benefit from strong capitalization, favorable earnings, and generally supportive conditions.

Barring an unusually large catastrophe event, the non-life reinsurance market is expected to maintain favorable earnings, per AM Best. The central question is whether reinsurers can preserve underwriting discipline and pricing integrity as capital accumulates and competition increases.

"If underwriting discipline and pricing integrity can be maintained despite record levels of capital, the industry may indeed be in the midst of a meaningful evolution of the reinsurance market," said Michael Lagomarsino, senior director at AM Best. "If not, history may once again demonstrate that the fundamental dynamics of supply, demand, and competition remain remarkably persistent."
