Gallagher Re's July 2026 First View recorded property catastrophe rate cuts of 20 to 25 percent for top-performing North American accounts. For cedant actuaries the more consequential shift is structural: aggregate covers, multi-year deals, multi-line arrangements and frequency cat covers are now available in volume at attachment points cedants can actually use.
The pricing question that follows is not what the aggregate costs. It is what the aggregate still leaves retained.
Key Takeaways
- 20 to 25 percent property cat rate reductions for top-performing North American accounts came with four structures that had largely left the market through the 2022 to 2024 hard cycle.
- Four $18 million events against a $25 million per-occurrence retention produce zero recovery. The same season under a $60 million aggregate attachment returns $12 million, and leaves $60 million net retained.
- $648 billion of dedicated reinsurance capital at year-end 2025, up 11 percent against premium growth of just over 1 percent, is the supply condition paying for the structural flexibility.
- 14.7 percent risk-adjusted property cat decline at January 2026, the sharpest since 2014, widening to as much as 25 percent by June, with retrocession down a further 16.5 percent.
- 14 to 15 percent projected reinsurer ROE for 2026 against nearly 19 percent in 2025. Frequency-sensitive structures are the first products withdrawn when returns approach cost of capital.
What Gallagher Re Recorded at July 1
Reinsurers withheld structural flexibility through nearly the whole 2022 to 2024 hard market. Capacity was scarce enough that cedants took whatever attachment and term the market offered, and products that respond to frequency rather than severity were the first to go. At July 2026, Gallagher Re describes a "renewed focus on more creative and efficient risk transfer solutions", with four structural types trading at volume rather than as isolated placements.
They are not interchangeable in a cedant's capital model. An aggregate cover responds to cumulative losses across a treaty period rather than to any single event. A multi-year deal locks a rate across a two or three year term. A multi-line arrangement combines property and casualty on a shared limit. A frequency cat cover triggers on an occurrence count, responding from the third or fourth qualifying event rather than on cumulative dollar loss.
| Structure | What It Protects | Capital Model Implication |
|---|---|---|
| Aggregate cover | Cumulative frequency of losses across the treaty period, not any single event | Smooths earnings volatility; requires continuous tracking of cumulative ceded-eligible loss against attachment, not event by event |
| Multi-year deal | Rate certainty across a two- to three-year term | Requires pricing future rate-trajectory risk and reinstatement or reopener mechanics; concentrates counterparty credit exposure |
| Multi-line arrangement | Correlated or diversifying losses across property and casualty (or other combined lines) on one shared limit | Requires modeling divergent loss-development tails sharing a single limit; basis risk from lines developing at different speeds |
| Frequency cat cover | Occurrence-count triggers (e.g., the third or fourth event in a period) rather than cumulative dollar loss | Protects against a high-frequency, moderate-severity season; requires occurrence definition aligned with the underlying per-occurrence tower |
The supply side explains the generosity. Dedicated reinsurance capital closed 2025 at $648 billion, up 11 percent year over year, while sector premium growth ran at just over 1 percent. Global insured catastrophe losses totaled $38 billion in the first half of 2026 through mid-June, below the ten-year average, leaving loss budgets largely intact. Gallagher Re projects reinsurer ROE at 14 to 15 percent for 2026, down from nearly 19 percent in 2025.
Howden Re's parallel data is more pointed. Its January 2026 report recorded a 14.7 percent risk-adjusted decline in property catastrophe pricing, the sharpest year-on-year drop since 2014, with retrocession falling a further 16.5 percent. By June 2026 risk-adjusted property cat rates were down as much as 25 percent on a weighted-average basis.
The Corridor an Aggregate Cover Leaves Behind
The variable that decides whether an aggregate cover is worth buying is the band of loss it does not reach, and it rarely appears in a renewal negotiation that stops at rate and attachment.
Take a mid-size regional carrier retaining the first $25 million of any single event and ceding $50 million of limit above that attachment. Four discrete severe convective storm events in one season, each producing $18 million of gross loss, generate zero recovery. No individual event breaches the retention, so the tower never responds however many times the pattern repeats.
An aggregate changes that arithmetic directly. Structured with a $10 million per-event franchise, so only losses above that threshold accumulate, and a $60 million aggregate attachment carrying $40 million of limit, the same four $18 million events each clear the franchise and accumulate to $72 million of eligible loss. That crosses the attachment by $12 million and triggers a $12 million recovery, the reinsurer's first payment of the season. The cedant still retains $60 million net.
That retained band is where reserve development surprises originate. Because the cover does not respond event by event, the quarterly reserve process has to track cumulative ceded-eligible loss against the aggregate attachment continuously rather than at renewal. A carrier that books each event's net retained loss without running the aggregate total understates IBNR relative to the recovery it will realize, or books recovery early against a threshold a subsequent quiet quarter never crosses.
Multi-year deals carry the same problem in the pricing rather than the reserving. With rate falling, reinsurers now load for the opposite risk they carried in 2023: being contractually bound to a rate that looks generous relative to where the market lands in year two or three. Most manage it by writing annually resetting limits with a pre-agreed reinstatement premium schedule rather than a single multi-year aggregate. Two quotes differing mainly in reinstatement terms rather than headline rate carry materially different expected costs, and a rate-on-line comparison will not surface that.
What the Structure Costs to Administer
The analytical cost of a custom structure is real and clusters in three places, none of which shows up in a premium comparison.
Basis risk is the most direct. A multi-line treaty layers two lines with fundamentally different development tails onto a single limit: property losses report and settle within a year or two, while casualty losses on the same treaty can develop for a decade. Pricing it needs either separate loss triggers by line, which reintroduces the complexity the format was meant to remove, or a blended trigger that leaves the cedant exposed to whichever line consumes the shared limit first.
Audit and disclosure complexity is the second. A per-occurrence tower is straightforward to explain to a reserve committee or an examiner: an event happens, a loss reports, the treaty responds on a published schedule. Year-end IBNR treatment for an aggregate with an open corridor is not. If cumulative losses sit below the attachment at year-end but a pending claim could push the total across it, the reserving actuary has to decide whether to book an expected ceded recovery for a threshold not yet crossed, and defend that judgment to an auditor who has not seen the structure before.
Counterparty concentration is the third, and it grows with multi-year tenor specifically. A three-year aggregate placed with a single reinsurer locks in three years of credit exposure without the annual checkpoint that would let a cedant reassess security or rebalance the panel. Credit risk functions typically size counterparty limits against a rolling annual exposure, so a multi-year placement concentrating several years of expected recoveries can breach those limits where the equivalent annual placement would not.
The window on the structures themselves is narrower than the window on rate. Howden Re describes industry economic value-added as "visibly compressing" toward neutrality, warning that a further leg down of similar magnitude would push large segments below cost of capital by 2027. Frequency protection is what erodes a reinsurer's earnings-volatility budget fastest after a bad year, which is why it is the first thing withdrawn when returns tighten, well before per-occurrence severity pricing moves.
