The LMA's model for CDR expansion is structurally sound. Whether London Market carriers have the architecture to match it is a different question entirely.
The Lloyd's Market Association has framed 2026 as a year of significant transition. Joe Brace, the LMA's Operations Director, has been clear about the priority: continued rollout and adoption of the Core Data Record across the vendor ecosystem. The market has agreed to speak a common data language. Every system, at whatever stage of development, needs to learn it.
The progressive accumulation model is the right approach. The CDR started with open market placing in 2023, then extended into treaty, and is now moving through claims and into delegated authority. Each step builds on the last. Each step requires carriers to capture, validate, and exchange standardised transactional data across a wider set of processes than before.
What progressive accumulation surfaces, though, is a question most carriers haven't answered honestly. Not “are we capturing CDR fields” but “does our architecture allow us to accumulate an expanding data standard at a pace we control.”
Mission first. That's how we think about it. The mission is CDR adoption. The measure is whether your architecture can absorb it. The manpower question is whether your team has the authority and the capability to act. And management is the last consideration, not the first. Too many carriers have inverted that sequence. They're managing a vendor relationship when they should be interrogating whether the vendor's architecture serves the mission at all.
What 68 carriers tell us
The Specialist Insurance Transformation Practice has structurally assessed 68 London Market participants across nine dimensions: mission precision, governance maturity, data architecture, knowledge ownership, AI substrate readiness, and the four organisational execution dimensions (mission alignment, measures, manpower and empowerment, management) that determine whether any strategy actually translates into operating reality.
Nearly half, 48.5%, hold their knowledge architecture in vendor controlled infrastructure. That means their accumulated underwriting judgement, claims patterns, and portfolio intelligence sits in a platform they don't own. When the CDR extends from accounting into placement, the carrier's ability to absorb that extension depends on the vendor's roadmap, not the carrier's strategy. That's not an adoption challenge. That's a structural dependency.
The governance picture reinforces this. 88.2% of assessed carriers operate at what our methodology classifies as governance tier 3. Functional, but structurally constrained. 11.8% have reached tier 4, where the operating model is mature enough to absorb progressive data standard expansion without architectural intervention. None has reached tier 5.
This is not about technology readiness. It is about who owns the architecture into which CDR data accumulates. Carriers who own it can move at their own pace. Carriers who don't are waiting for someone else to decide when and how the CDR lands in their operating model.
Where Blueprint Two fits
The CDR and Blueprint Two converge on the same structural requirement. Blueprint Two's central mandate is digital processing through standardised data exchange. The CDR is the data standard that makes that possible. They are not separate programmes. They are the same architectural question asked from two directions.
The Specialist Insurance Transformation Practice delivered the only compliant Blueprint Two Phase 1 and Phase 2 offering in the world. That six person team's work was recognised with the ACORD Vanguard Award. The experience is specific: the carriers best positioned for CDR progressive accumulation are the ones whose architecture was designed for data sovereignty from the outset. The carriers most exposed are the ones treating CDR adoption as a vendor deliverable rather than an institutional capability.
The question for your board
If you're a syndicate, managing agent, or MGA thinking about CDR readiness, the structural question is straightforward. Do you own your knowledge architecture, or does your vendor? Can you absorb an expanding data standard at a pace your board sets, or are you waiting for a platform update?
Our team met with Joe Brace and the LMA at the Lloyd's building this week to discuss exactly this. If this is a conversation your organisation needs to be part of, we welcome the introduction.
