Rising health costs strain employer plans. Marsh's new captive solution Nexus lets midsize multinationals self-insure benefits with lower admin burden. $3B in captive premium.
Marsh launched a new captive insurance solution, Marsh Nexus, aimed at multinational companies struggling with rising employee health costs. The product targets firms with at least $3 million in annual benefits spend outside the United States.
The Marsh Health Trends 2026 report projects double-digit cost increases for employer health plans across most global markets. Many multinationals lack the scale or resources to build a sustainable self-insurance program through a single-parent captive.
Marsh Nexus operates as a cell captive within Marsh's Mangrove Protected Cell Company, domiciled in Washington, D.C. The structure lets a company retain risk without the administrative burden of a full parent captive. Marsh handles the portfolio management.
Paul Lewis, Mercer Marsh Benefits' Multinational Advisory Growth Leader, said: "With the continued trend of rising global healthcare costs, organizations are focused on how to balance cost management while still providing valued, personalized employee benefit programs across the world."
He added that the solution reduces administrative effort and costs associated with a single parent captive. "Marsh Nexus is a cost-efficient vehicle that complements broader benefits strategies and supports multinational organizations in optimizing next-generation employee benefit programs."
Donna Weber, Marsh Captive Solutions' Global Pooling and Cell Facilities Leader, noted that captive use for international employee benefits has more than doubled in the last five years. More than 140 companies now hold over $3 billion in such captive premium.
"Through the power of Marsh – the world's largest captive insurance manager – Marsh Nexus enables clients to take an off-the-shelf, low-cost approach to risk retention and break new ground in managing mounting international employee benefits costs," Weber said.
The captive market for employee benefits has grown rapidly. For firms with a global workforce and health cost inflation running at 10% or more per year, the cell captive offers a way to stabilize expenses without absorbing the full volatility of a self-insured plan. Marsh's scale and existing infrastructure reduce setup time and legal costs compared to a custom captive.
The threshold of $3 million in non-U.S. spend means the product fits mid-sized multinationals that fall below the typical single-parent captive minimum. That group represents a large pool of potential users, given the breadth of global employers with several hundred workers spread across multiple countries.
More than 140 companies now use captive structures for international benefits, with combined premium exceeding $3 billion. Marsh Nexus aims to capture a share of that growing segment by lowering the entry barrier.
