Risk-adjusted property catastrophe rates-on-line fell as much as 25% at the June 1, 2026 renewal, against 14.7% at January 1 and 16% at April 1. The rate numbers are the visible part of Howden Re's report. The consequential part is that global reinsurer economic value added, the spread between return on invested capital and weighted-average cost of capital, is now in low single digits and narrowing.
Key Takeaways
- 900 basis points of incremental decline between the April and June renewals, against roughly 130 between January and April. The pace is increasing, not levelling.
- 7.7% median WACC for global reinsurance in 2024 on AM Best's analysis, down from 8.1% in 2023 and compressing to roughly 6.7% in early 2025, against a CAPM cost of equity near 7.5%.
- 20% or more expected return on capital was what Goldman Sachs estimated property catastrophe carried at hard-market pricing, before a cumulative decline of 25% or more through June 2026.
- $1.0 billion of new business contractual service margin at Swiss Re P&C, down from $1.4 billion, which prices the forward margin the firm gave up rather than defend share.
The Curve Is Steepening
| Renewal Date | Risk-Adjusted Rate Change | Incremental Decline |
|---|---|---|
| January 1, 2026 | -14.7% | Baseline |
| April 1, 2026 | -16.0% | -1.3 pts |
| June 1, 2026 | Up to -25.0% | -9.0 pts |
The January to April step was about 130 basis points. April to June was up to 900. Loss-free programmes moved further still, and Howden Re described lower-attaching Florida layers as showing significantly broader appetite and more competitive pricing than at any renewal since COVID-19.
Capacity explains the level. The June renewal ran at a 1.6 times ratio of supply to demand, cat bond risk capital outstanding reached new highs, and reinsurers reopened structures constrained since the 2023 hard market: prepaid reinstatements, aggregate covers, second-event protection and combined structures with sideways coverage.
What is not happening is terms erosion. KBW logged property cat declines approaching 20% at mid-year with terms and conditions holding firm, and Munich Re's management described competition as still mainly on price. In the previous soft cycle, attachment points and conditions loosened alongside rate. Here the degradation is purely economic: the same risk at the same attachment, priced lower.
The Spread, Not the Rate, Is the Constraint
Economic value added is positive when return on invested capital exceeds the weighted-average cost of it, and rational capital exits when it turns negative. That is the number the renewal is walking toward.
AM Best puts the sector's median WACC at approximately 7.7% for 2024, down from 8.1% in 2023 and compressing to roughly 6.7% in early 2025 as rate volatility subsided. The CAPM median cost of equity runs near 7.5%. The Market-Derived Capital Pricing Model, which reads future volatility off option prices rather than history, puts it closer to 16%, and that is the measure that accounts for tail risk in a reinsurance portfolio.
The return side started with room. Median sector ROE was 15.7% in 2024, and Goldman Sachs estimated property catastrophe business carried expected returns on capital of 20% or more at hard-market pricing. Take 25% or more of cumulative rate out of that and the expected return compresses mechanically toward the CAPM cost of equity, before any deterioration in loss experience.
Howden Re's David Flandro states the position without rounding it up: collective EVA is still positive and in the low single digits, "but the floor isn't very far away." A low-single-digit spread declining at an accelerating rate leaves no margin for a second variable. One more renewal on this trajectory, or a single major loss impairing capital while rates are already thin, flips the spread for a meaningful share of the market.
Two firms are pricing that arithmetic rather than describing it. Swiss Re earned $1.5 billion of group net income in Q1 2026, up 19%, on a 79.5% P&C combined ratio, and cut natural catastrophe volumes 11% year to date with April renewal volumes down 8% and net price down 6.1% after risk and exposure adjustment. The measure that matters is forward: new business contractual service margin fell to $1.0 billion from $1.4 billion. Swiss Re is not only writing less; what it writes carries a lower expected margin, and it gave up roughly $400 million of forward profitability rather than defend volume.
Munich Re did the same at April, cutting premium 18.5% to about EUR 2.0 billion on risk-adjusted prices down 3.1%, while reporting a 66.8% P&C reinsurance combined ratio and 19.7% ROE off the hard-market book. Proportional business took the largest reductions, which is the expected order: the cedent retains less, so the reinsurer's margin thins first.
The Last Cycle's Floor Was Set by a Hurricane
The 2013 to 2017 softening is the direct precedent, and it did not end because reinsurers exercised discipline.
Property catastrophe pricing fell more than 50% cumulatively across that stretch on the same three forces: abundant capital, benign losses and fast-growing alternative capacity. Alternative capital more than doubled from roughly $35 billion in 2012 to $71 billion by 2017, reaching about 20% of dedicated property catastrophe capacity, while global cession rates fell from around 12% in 2009 to 9% by 2015 as primary insurers retained more against cheap reinsurance.
The economics did reassert, and late. By 2016 and early 2017 several major reinsurers were reporting combined ratios above 100% on property catastrophe portfolios in a benign loss year, and real industry growth had fallen below 1% globally between 2013 and 2015. The response was consolidation rather than repricing: PartnerRe and EXOR, Platinum and RenaissanceRe, Montpelier and Endurance all closed in 2015 and 2016.
What actually reset the market was Harvey, Irma and Maria, over $90 billion of insured losses, trapped ILS collateral and adverse reserve development, repriced at January 2018.
The buffer today is thicker, and that cuts the wrong way for anyone hoping discipline arrives sooner. Aon put reinsurance capital at $785 billion at the April 2026 renewal against roughly $600 billion at the 2017 pre-event peak, with alternative capital more diversified and cat bond risk capital at records. A thicker buffer means the industry can absorb deeper rate declines before financial stress forces the correction, so the point at which the market stops is further down than it was last time.
And it is being approached faster. Moving from negative 14.7% to negative 25% in five months exceeds the pace of any single year in the 2013 to 2017 decline, into a market whose capital base is better able to keep absorbing it.
