LONDON, May 06, 2026 (GLOBE NEWSWIRE) — Specialty insurance market rates declined in 2025 and for 1 January 2026 renewals, with the pace of change exceeding expectations in the published forecasts by both brokers and insurers, according to WTW’s Specialty Insurance Marketplace Survey (SIMS).
The WTW survey reflects around $250 billion of gross written premium over a 10-year cycle, including $45 billion in 2025, and covers specialty insurers operating across the London, Bermuda and the U.S. excess and surplus (E&S) markets. Rather than using broker-derived data, the survey is built exclusively on data contributed by clients of WTW’s Insurance Consulting and Technology business that participate directly in SIMS.
Based on the SIMS insurance rate index, expected performance (which is net of exposure trends) in 2025 has unwound the rate strengthening gains of the last few years back to levels last seen in 2021. 2025 was the first year since 2018 for which rate adequacy for new business was lower than for renewal business.
Data from 1 January 2026 renewals and new business point to continued rate softening, with a 10-point decline in the insurance rate index, back to 2020 levels.
Richard Clarkson, Global Market Leader, Global Specialty, WTW, said: “Our intention is to provide insights on Specialty market dynamics that hasn’t been possible before – using market derived data to deliver a consistent view of risk adjusted rate change over a large number of classes and key geographies, aligned to how underwriting teams are organised. Our clients already use this to validate business plans, compare current year rating trends, assess impact of new and renewal rate adequacy and support reserving processes.”
For 1 January 2026 renewals, 75% of the 42 material classes show rate decreases (on a gross-of-claims-trend basis), compared with 30% of classes in 2024. The inclusion of claims trend data within SIMS allows for a more complete picture of expected profitability movements. In particular, the survey shows that aggregated insurance rates decreased by 5% gross of claims trend and 8% net of claims trend (i.e. adjusted for actuarial-estimated inflation in claims costs over and above what is captured in rate change data).
The findings also highlight the speed of recent market movements. An approximate 45% cumulative rate increase was achieved between 2017 and the market peak in 2023, with around half of that increase eroded over the past two years.
The most pronounced rate decreases are in Property and Energy, followed by Marine, Financial Institutions and Professional Liability, reflecting benign catastrophe experience and distorted frequency/severity trends, offset by higher geopolitical tensions.
The general liability and medical malpractice markets are behaving counter-cyclically to the overall insurance markets. Substantial concerns relate to social inflation, nuclear jury verdicts and the expansion of litigation funding in this market. We do not believe this trend is sustainable, but how this might change in the short-term remains uncertain.

SIMS provides a consistent view of rate movements across specialty markets, allowing carriers to assess how conditions evolve across both new business and renewals. The survey’s detailed segmentation provides a level of result granularity for participants not available elsewhere, with the data highlighting the pace at which market conditions are shifting and support more informed benchmarking and performance management.
