Property-catastrophe reinsurance rates fell at their steepest pace in years across the first half of 2026. Record capital and a benign loss year shifted pricing power firmly to cedents, according to a mid-year industry report by Ledger Investing.
Reinsurance capital reached a record $785 billion at year-end 2025. Third-party capital rose 18% to approximately $136 billion per Aon. That surplus has been the primary driver of rate competition through every renewal this year.
Risk-adjusted rate-on-line fell 14.7% at January 1 per Howden Re. Rates steepened further to 15% to 20% at the April Japan renewal, then to 15% to 25% across Florida and the US Southeast at June 1. Guy Carpenter placed the typical June 1 range at 15% to 20%; Howden Re reported up to 25%, with some remote layers off as much as 27.5%.
A loss-free 2025 season compounded the pressure. There were no US hurricane landfalls for the first time in a decade. Global insured losses ran approximately US$107 billion to US$127 billion, down about 24% year-on-year on Swiss Re estimates.
Despite the broad rate movement, brokers were clear that structural discipline held. Reinsurers competed hard on price while maintaining attachment points and terms. Capacity returned to structures withheld in recent years: prepaid reinstatements, aggregate covers and cascading all-perils coverage.
The cedent-level data from Florida show how far conditions have shifted. Florida Citizens Property Insurance Corporation finalised its 2026 risk transfer programme at US$2.816 billion. New placements came in roughly 30% cheaper than equivalent cover a year ago, with the net rate-on-line falling to 8.46% from 11.95% in 2025.
The cat bond market ran in step with the broader softening. Year-to-date 144A and private issuance surpassed US$16 billion through early June 2026. The outstanding market reached approximately US$63.9 billion at end-March. Gallagher Securities reported pricing down more than 20% year-on-year as of early March.
Investor demand behind that pace shows little sign of easing. A Gallagher Re and Gallagher Securities survey of more than 60 investors found about 90% plan to increase ILS allocations over the next two years. Insurance-related holdings already average 12% of respondents' portfolios.
Casualty ILS attracted sustained institutional interest in the first half of 2026, though completed deal volume lagged considerably. US casualty cedents largely held reinsurance pricing risk-adjusted flat per Gallagher Re's 1st View. Investors have begun to treat casualty as a separate sleeve outside their property-cat budgets. Aon estimated casualty sidecar vehicles at US$1.7 billion of a total sidecar market of $19.6 billion as of Q3 2025.
Deal execution is the constraint. A minimum casualty sidecar commitment runs approximately $50 million of capital, or roughly US$150 million to US$200 million of premium. The asset class is non-commoditised, with multi-year commitments and no standardised templates. Three large reinsurers exited the US medical market at the June renewal, a move Gallagher Re characterised as permanent. That gap opens a route for ILS and captive solutions.
Colorado State University's June update called for 11 named storms, five hurricanes and two major storms, against a 1991-2020 baseline of 14, seven, and three. A below-average forecast does not eliminate tail risk, and the supply side faces its own reckoning.
Howden Re warned that a further pricing decline of similar magnitude could push large segments of the industry below their cost of capital by 2027.
"Capital has rarely been more abundant in an environment of elevated risk exposure," said David Flandro, head of industry analysis and strategic advisory at Howden Re. "How much further pricing will fall before economics reassert themselves is the question that will define Jan. 1, 2027."
