Reinsurance Trusts in Captive Insurance: Structure and Strategy

In this episode of The Edge of Risk Podcast by IRMI, host Joel Appelbaum speaks with Donny Tong, senior vice president at Truist Bank, about the role of reinsurance trusts—also referred to as "collateral" trusts—in captive insurance programs. The discussion explores how these trust structures function as collateral mechanisms between captives, fronting insurers, and reinsurers, including the operational mechanics behind trust agreements, eligible assets, withdrawal rights, and trustee responsibilities. Mr. Tong explains why many fronting insurers increasingly favor trust arrangements over letters of credit due to their operational simplicity, streamlined administration, and ability to provide ongoing visibility into collateral assets.

The conversation also examines how reinsurance trusts compare with other collateral options such as letters of credit and funds withheld arrangements. Topics include investment flexibility within trust accounts, liquidity considerations, balance sheet treatment, multibeneficiary and multicell trust structures, and the growing demand for master trust frameworks. Mr. Tong also shares perspectives on how market conditions, liquidity pressures, and rising letter-of-credit costs may continue driving adoption of collateral trusts across the captive insurance industry in the years ahead.
