The Lloyd's insurance market delivered a return on capital exceeding 20% in 2025, sustaining this performance level for a third consecutive year, according to a new report by AM Best.
Market Stability and Performance
AM Best’s Best’s Market Segment Report highlights that while the ranking of the 20 largest syndicates has shifted over the past decade, the changes represent a re-ordering rather than a structural shift. Nine of the top 10 syndicates in 2025 were also among the largest ten in 2015, indicating significant continuity in market leadership.
What the Numbers Show
The strong capital returns in 2025 were supported by favorable reserve dynamics despite deteriorating underlying underwriting metrics. The report notes an increase in both expense and attritional loss ratios during the year. However, these pressures were offset by a lower-than-average large loss experience and continued prior year reserve releases. This divergence suggests that the headline profitability was partially sustained by non-recurring reserve benefits and benign catastrophe experience, rather than pure operational underwriting margin expansion.
Outlook and Cycle Dynamics
Tim Prince, director of analytics at AM Best and the report’s author, identified the attritional loss ratio as a key indicator of the underlying market cycle, noting that peaks typically occur during the softest parts of the cycle.
Looking ahead to 2026, AM Best expects competitive pricing conditions to exert further upward pressure on the attritional loss ratio. When combined with a normalization of large loss experience, these factors could meaningfully increase the overall combined ratio, potentially challenging the sustained high returns seen in recent years.
How might Lloyd's syndicates adjust their pricing strategies in 2026 to counteract the expected rise in attritional loss ratios?
What specific operational measures could insurers implement to reduce expense ratios, given that they have been increasing alongside loss costs?
To what extent will the normalization of large loss experience in 2026 impact the profitability of reinsurance contracts versus primary insurance lines?
