Tokenized Cat Bonds: Blockchain Ownership Remains Elusive

The traditional minimum denomination for catastrophe bonds is $250,000, but a new tokenized structure could reduce this to approximately $5,000. However, this reduction does not automatically mean that thousands of smaller investors would each hold a catastrophe-bond note in their own right.

The central distinction lies in the legal and economic aspects. The lower threshold can be created by selling beneficial interests in a vehicle that holds the bonds, rather than breaking a bond into directly owned on-chain pieces. This is a meaningful change in access, but it is not the same as putting the legally enforceable ownership record for the underlying instrument on a blockchain.

A recent pilot by HCI Group and SurancePlus uses a $5,000 threshold for tokenized reinsurance securities, available to qualified U.S. accredited investors under Regulation D and qualified non-U.S. investors under Regulation S. However, this is not direct ownership of a catastrophe bond, as the underlying programmes remain separate from the tokenized securities.

A more significant development is proposed by Harneys and droppRWA, targeting an early-2027 test issuance of catastrophe bonds where the legally enforceable ownership record would sit directly on a blockchain. This structure could reduce reconciliation from days to seconds and move beyond a token representing an interest in or return stream linked to another arrangement.

The regulatory framework remains a critical component in determining the success of this proposed structure. The Bermuda Monetary Authority is assessing tokenized investments according to their economic substance rather than simply the technology used, highlighting the need for a nuanced understanding of what an investor owns, what rights attach to the token, and which entity bears the relevant obligations.
