ALIRT Insurance Research’s recent analysis has revealed that Excess & Surplus (E&S) lines direct premium growth slowed considerably in the first half of 2026, following years of record expansion as the insurance pricing cycle shifts.
In ALIRT’s annual U.S. Surplus Lines Overview, which examines industry-wide trends and the financial performance of its 50 Company E&S Lines Composite, E&S direct premium growth moderated to an annualised 2.8% through H1 2026, in line with overall U.S. P&C direct premium growth.
This represents a considerable slowdown following years of double-digit annual growth. U.S. surplus lines direct premiums written reached $143.3 billion in 2025, representing a 30-year high of 12.9% of total U.S. property and casualty insurance premiums.
ALIRT noted that the slowdown marks a significant shift from the prolonged hard insurance market of 2018–2025, during which U.S. surplus lines premiums increased by approximately 187%, substantially outpacing growth in the broader property and casualty industry.
Easing insurance prices and the rapid expansion of specialty insurance distribution platforms were identified as the main factors behind the slowdown.
The proliferation of managing general agents (MGAs), managing general underwriters (MGUs), programme administrators and fronting insurers – partly supported by private equity investment and alternative reinsurance capital – has expanded market capacity and intensified competition.
As admitted insurers increasingly reassess risks previously transferred to the E&S market, ALIRT anticipates further pressure on surplus lines premium growth.
Despite the moderation in premium growth, ALIRT noted that leading surplus lines insurers remain in a favourable financial position.
ALIRT’s Composite, representing approximately $73 billion in 2025 direct premiums written, has produced some of its strongest underwriting results in two decades. Pretax operating returns on net premiums earned have remained in the 25%–35% range over the past two and a half years, well above the Composite’s long-term average.
The Composite’s aggregate policyholder surplus reached approximately $45 billion at 30 June 2026, an increase of nearly 300% since year-end 2004.
ALIRT’s proprietary financial scoring analysis further confirms continued balance sheet strength.
Looking ahead, ALIRT stressed that strong E&S market performance will depend on disciplined underwriting, prudent capital management and the ability to adapt to more competitive market conditions.
The report also highlighted the importance of evaluating individual insurer financial strength, particularly because surplus lines policyholders generally do not benefit from state insurance guaranty fund protections.
While larger surplus lines carriers frequently benefit from their integration within well-capitalised insurance groups, the expanding number of newer specialty insurers and fronting platforms creates additional considerations for brokers, counterparties and institutional insurance buyers.
As the market transitions away from its prolonged growth cycle, ALIRT expects insurer financial performance and credit quality to remain important areas of scrutiny.
