Credit ratings agency AM Best said the outlook for the insurance industry in the London market remains stable, with profitability expected to slow in 2026 as long as disaster experience remains within normal limits, but remains optimistic.
AM Best said a combination of pricing dynamics, investment conditions and evolving global risks continued to shape the market’s trajectory.
The agency noted that while pricing conditions have begun to soften across several product lines, they remain generally sufficient to support underwriting performance.
At the same time, relatively high interest rates are expected to maintain favorable investment yields, providing some support for overall profitability. However, AM Best highlighted that a range of uncertainties could weigh on the sector, including geopolitical instability, climate-related risks and the growing challenge of unmodeled risks.
AM Best stressed that the London market remains an important global center for commercial and specialty insurance, underpinned by deep underwriting expertise and a robust regulatory framework.
The market’s ability to develop customized insurance for complex risks continues to enhance its appeal on the international stage. Strong underwriting results and profitability recorded between 2023 and 2025 are underpinned by solid market conditions and relatively manageable catastrophe losses, although recent trends suggest pricing will ease, particularly in real estate and short-tail segments.
Looking ahead, AM Best expects ongoing community inflation and historical reserve pressures to continue to impact casualty insurance, where pricing adequacy may remain under review. While rates in these segments are still considered adequate, they are gradually declining from their previous higher levels. As a result, AM Best expects overall profitability to slow down in 2026 compared with recent years, but remains optimistic.
Investment strategy remains a key factor underpinning returns. AM Best observes that London market firms generally maintain portfolios weighted towards fixed income securities with good credit quality, while major markets such as the UK, EU and US continue to provide resilience against inflationary shocks.
Central bank policies, driven in part by geopolitical tensions, may keep interest rates higher for longer, which AM Best believes will benefit insurance companies’ investment income.
The report also noted that continued M&A activity is evidence of the attractiveness of the market. Several major transactions have taken place, solidifying the buyout firm’s position in the specialty insurance and reinsurance sector. AM Best noted that these transactions typically enhance the capabilities and reach of the London market, including participation in the Lloyd’s platform.
At the same time, the growing role of alternative capital is reshaping the competitive landscape. AM Best explains that insurers are making greater use of catastrophe bond and collateralized reinsurance structures to access institutional capital and support underwriting capacity. While this trend can improve return on equity and aid cycle management, it can also lead to weaker market conditions as more capital enters the industry.
AM Best warned that an influx of third-party capital, combined with strong retained earnings in recent years, heightened the risk of further pricing pressure. As such, rigorous underwriting and prudent cycle management are expected to become increasingly important to market participants.
Exposure to massive losses remains a defining feature of the London market. AM Best highlights that insurers face significant risks from natural and man-made disasters, with the costs of such events rising over time. Secondary hazards including wildfires, convective storms and droughts account for an increasing share of losses, while non-traditional risks such as epidemics and geopolitical conflicts highlight the limitations of existing models.
AM Best specifically warned that the ongoing crisis in the Middle East could bring significant losses to the London market, particularly given its role in underwriting risks in the maritime, energy and political violence sectors. This development could test the resilience of insurers and put additional pressure on pricing and capital management.
The organization also draws attention to the increasing complexity of cyber risks, where cumulative exposure and systemic threats require careful assessment. AM Best said that as online businesses grow in size and importance, the need for robust pricing and risk modeling will intensify.
Overall, AM Best believes that while the London market is well prepared to deal with current challenges, the balance of risks is changing. Profitability is expected to remain positive but more constrained, with performance increasingly reliant on disciplined underwriting, prudent capital management and the ability to respond to a rapidly changing risk environment.
