Lloyd’s reinsurance business delivered £1.7 billion ($2.3 billion) in underwriting profits with an 88% combined ratio in 2024, but the market’s largest segment faces significant pressure from California wildfires that could consume a third of its 2025 catastrophe budget, according to analysis from AM Best.

The Lloyd’s reinsurance segment, representing approximately one-third of the market’s gross written premium at £18.7 billion ($25.3 billion), has experienced remarkable expansion with a five-year compound annual growth rate of 9%, according to the report. Specialty reinsurance led the charge with 11% annual growth, while property and specialty lines drove an 8% premium increase in 2024.

The property reinsurance segment emerged as the standout performer, achieving a 75% combined ratio supported by favorable pricing conditions and prior-year reserve releases from major catastrophe events including hurricanes Ian and Ida, AM Best noted.

Market Faces Divergent Segment Performance

While property reinsurance thrived, other segments showed signs of strain. Casualty reinsurance deteriorated to a 98% combined ratio from 90% in 2023, despite apparent rate adequacy, as syndicates grappled with adverse development from pre-2019 business, according to the report. The specialty reinsurance segment fared worse, reporting a 106% combined ratio amid slowing rate increases and significant losses including the Baltimore bridge collision and strengthening Ukraine conflict-related aviation claims.

The California wildfire losses, estimated at £1.7 billion ($2.3 billion) for the overall Lloyd’s market, present an immediate challenge for 2025 profitability. This single event threatens to consume one-third of the market’s annual natural catastrophe allowance before the Atlantic hurricane season even begins, highlighting the segment’s vulnerability to clustered catastrophe events.

The market’s heavy reliance on broker distribution adds another layer of complexity, the report noted. With business often passing through multiple distribution channels before reaching syndicates, Lloyd’s faces both higher costs and increased exposure to price-based competition from more streamlined competitors.

Capital Innovation Essential for Cycle Management

As market conditions soften and catastrophe losses mount, Lloyd’s capital framework becomes increasingly critical. The market’s robust capital regime, featuring risk-based member-level requirements and a 35% uplift, provides important buffers. The “Coming into Line” process enables rapid capital replenishment after losses, maintaining stability even after major events, AM Best said.

Lloyd’s has also embraced innovation through its London Bridge risk transformation platform, which reached approximately $2 billion in capital deployment across 19 cells by end-2024. This vehicle facilitates institutional investor participation through preference shares and debt securities, diversifying the market’s capital sources beyond traditional Lloyd’s businesses.
