How Emerging Models of Tokenized Deposit Interoperability Work
UK's biggest banks just completed live customer transactions using interoperable tokenized sterling deposits. NatWest, HSBC, Barclays and Lloyds just executed two remortgage completions and a consumer marketplace payment using tokenized deposits.
The strategic significance is not that banks are running another tokenized deposit test but that interbank interoperability is enabling concrete use cases to reach beyond an individual bank’s customer base.
Issuing a tokenized deposit creates a capability. Interoperability expands the market that capability can serve.
A programmable mortgage payment becomes more useful when it can coordinate parties banking at different institutions. A marketplace payment gains reach when buyers and sellers can use their existing banks. Digital securities settlement needs money that can connect to the platform on which the asset sits.
