Sisouda Dayre has joined Gallagher Re as operations director for Asia-Pacific, based in Singapore, covering operational governance, business transformation, and client servicing across the region. The appointment follows a specific sequence: Roshan Perera was appointed to lead the APAC region in February 2026 following the departure of Mark O'Brien and the retirement of Mark Morley, both of whom had held their roles for roughly 17 months. Leadership stabilisation followed by operational infrastructure investment is the standard platform build pattern - and the Dayre appointment is the operational governance layer that follows Perera's regional leadership appointment.
The background that makes Dayre analytically suited to the role is not reinsurance technical expertise but operating model build experience. She joins from Allianz Partners Health, where she spent three and a half years as regional head of health operations for Asia-Pacific, with her remit centred on operating model transformation and entity integration across APAC markets - precisely the capability a reinsurance broker building out an APAC platform requires as it adds complexity and scale. Before that, she served as global head of protection and resilience at Allianz Partners, spanning business continuity, crisis management, and IT service continuity globally. Her earlier career spans business continuity and operations roles at Société Générale in France and senior consulting positions, giving her operational infrastructure background that predates her insurance sector experience.
Louise Tyler, international chief operating officer at Gallagher Re, and Perera were named by Dayre as instrumental in the appointment.
Singapore serves as Gallagher Re's primary APAC hub. Risk-based capital regimes and climate risk stress tests across the region have drawn additional global reinsurance capacity to APAC markets - a structural dynamic that increases the operational complexity brokers must manage as they service a growing and more sophisticated cedant base. For a reinsurance broker building regional scale, the operational governance and business transformation remit Dayre carries is not a support function but a growth enabler: the ability to integrate new markets, manage entity complexity, and maintain client servicing standards across a diverse regional footprint is what determines whether expanded capacity translates into sustained business growth.
