Enstar's Cavello Bay to reinsure $2.3bn of Markel run-off reserves and provide $1.2bn adverse cover
Specialty insurers continue to pay to cap legacy reserve uncertainty while keeping claims control, which is a template other carriers with ageing books can copy. Run-off specialists with capital to deploy gain pricing power, while ceding insurers gain earnings clarity. Watch regulatory approval and whether similar structures appear from other mid-sized specialty groups.
What Happened
Cavello Bay Reinsurance, an Enstar subsidiary, entered an adverse development cover agreement with Markel Insurance covering a $4.8 billion run-off portfolio for underwriting years 2025 and prior. Markel retains the first $2.6 billion of reserves, Enstar reinsures the next $2.3 billion for $2.4 billion in consideration, and Enstar provides $1.2 billion of adverse development cover above the subject reserves. Markel keeps claims handling, and completion is expected by the end of Q4 2026, subject to regulatory approval.
