MS Amlin has launched a new property treaty consortium designed to increase underwriting capacity for property per risk business, with a particular focus on growing demand from global data centre risks.

The Property Treaty Per Risk Consortium increases MS Amlin’s maximum line size from $50m to $67.5m, representing a 35% increase in available capacity while retaining a single underwriting and claims structure.

The facility brings together four Lloyd’s syndicates alongside MS Amlin: Nephila Syndicate 2358, Nephila Syndicate 2359, Hampden Syndicate 2689 and Apollo Syndicate 1969.

MS Amlin will continue to act as lead underwriter and retain underwriting and claims authority across placements.

The company said the consortium structure is intended to simplify placements for brokers by consolidating multiple Lloyd’s capacity providers into a single coordinated offering.

Stephen Price, head of North American property reinsurance at MS Amlin, said: “This consortium increases our line size by more than a third, giving brokers access to additional A-rated Lloyd’s capital through a single placement while allowing us to maintain full oversight of underwriting and claims.

“By consolidating Lloyd’s capacity into a single smart follow offering, the consortium will simplify placement for brokers, reduce panel complexity, and ensure consistent terms and claims handling across the placement.

“In addition, the facility brings in new and diversified capital into the property treaty market from syndicates not traditionally active in this space, boosting Lloyd’s market capacity overall and increasing the relevance of Lloyd’s pricing and wordings stance in the global market,” said Price.

The launch comes as reinsurers and insurers face rising demand for larger limits linked to rapid expansion in global data centre infrastructure.

MS Amlin cited estimates from McKinsey projecting investment in data centre infrastructure could approach $7tn by 2030.

That growth is expected to increase demand for larger and more complex reinsurance placements, particularly around accumulation management and concentration risk.

Price added: “The challenge for the market is balancing the scale of capacity required with careful management of accumulation risks. Detailed understanding of exposures and careful risk selection will be essential as this emerging class of business grows.”
