The Lloyd's Market Association marks its 25th anniversary on June 28, having grown from a post-merger trade body into one of the most influential technical and representative organisations in the global specialty insurance market.
The LMA was founded in 2001 from the merger of several pre-existing associations, some dating back to the early 1900s, spanning marine, non-marine, aviation and members' bodies. Over the quarter-century since, it has shaped the Lloyd's market's response to some of the most consequential risk events in modern history.
In the immediate aftermath of 9/11, the LMA developed Terrorism Risk Insurance Act wordings that became a reference point for the market. It produced clauses addressing silent cyber risk and cyber warfare as those exposures emerged, and published the first communicable disease clause at the height of the COVID-19 pandemic. Its sanctions clause work has since taken on renewed relevance as geopolitical volatility has driven growing demand for clear contractual frameworks.
The market the LMA now serves looks very different from the one it was founded to represent. Lloyd's gross written premium reached £55.5bn in 2024, up 6.5% year-on-year, before growing further to £57.9bn in 2025, when the market delivered a combined ratio of 87.6% and a 10% increase in profit. Combined with the London company market, total London market premium exceeded £104bn in 2024, the second consecutive year above that threshold.
That growth now faces a more testing backdrop. Lloyd's chief of market performance Rachel Turk warned in the Q2 2026 Market Message that first-quarter renewals saw rates coming off faster than anticipated. She cautioned that top-line growth pressures can lead to underwriting discipline slipping, drawing an explicit parallel with conditions a decade ago when inconsistent cycle management could not be outweighed by the responsible actions of individual participants.
The LMA's work on AI has become one of its most active areas of engagement. A survey published by the association in April 2026, drawing on responses from firms representing over 60% of Lloyd's market stamp capacity, found that AI adoption had more than doubled in 12 months, with 93% of respondents having or developing formal AI governance frameworks. Deployment remains focused largely on operational efficiency rather than frontline underwriting or claims decision-making, with 72% of firms having AI frameworks in place and a further 21% developing them. More than 60% said human oversight of AI-generated outputs is mandatory.
The governance picture remains uneven, however. Around one in four firms still rely on general third-party risk management frameworks rather than AI-specific provisions, and concerns around data quality, bias and the reliability of AI outputs remain ongoing.
On the underwriting side, the LMA's wording expertise is being called upon directly. Lloyd's is working with the association on policy wordings designed to deliver greater clarity around what is and is not covered in cyber products, after Lloyd's warned that AI adds further uncertainty to the cyber risk landscape — both as a tool used by threat actors and as a source of unresolved coverage questions — with ambiguity remaining over whether underwriters intend cyber policies to include or exclude AI-related liability exposures.
The LMA has been a consistent driver of operational and technological change across the market, establishing the Lloyd's Wording Repository in 2007, introducing the GEMINI claims expert management system in 2018 and publishing the first Core Data Record in 2021. The ambition for market-wide digitalisation has, however, been tested by the prolonged difficulties surrounding Blueprint Two.
In March, Lloyd's announced it was transitioning away from the programme as part of its new five-year strategy, refocusing Velonetic on incremental technology modernisation and committing to partner with the market on process simplification and common data standards.
The LMA had been an active voice throughout, having secured a 10% reduction in Velonetic message-processing fees for managing agents, with the contract valued at approximately £80m a year for the market. The association continues to press for ACORD-compliant data standards and broader adoption of the Core Data Record across claims, delegated authority and underwriting, and has supported the implementation of mandatory operational resilience testing programmes in 2026, which mark the first full test cycles for the market.
The LMA Academy, recognised as the primary centre of technical training for the Lloyd's marketplace, supports professionals from entry level to non-executive director. In 2025, the LMA launched its inaugural Underwriting Talent Summit, drawing attention to the declining pipeline of female underwriting leaders in the market.
The association has been led by three chief executives since its founding: Simon Sperryn from 2001, David Gittings from 2006 and Sheila Cameron from 2019. Its chairs have included Stephen Catlin, Paul Jardine, Rupert Atkin, Neil Maidment, Andrew Brooks and, from 2026, Sean McGovern.
Sheila Cameron (pictured), CEO of the LMA, said: "Over the last quarter century, the LMA has evolved alongside the Lloyd's market in an ever-changing and riskier world. Throughout technological disruption, geopolitical uncertainty and a global pandemic, our role has not changed — to be a voice that supports our members and our market in the global insurance ecosystem and facilitates market growth, efficiency and development."
"As we enter our next chapter, we will continue to support members, influence key market developments and help grow the Lloyd's market's position as the home for global risk," Cameron added.
