A live transaction on Swift's blockchain ledger has connected Standard Chartered's and HSBC's separate tokenized deposit systems for the first time. The banks describe the execution as a step toward interoperable, 24/7 cross-border settlement.
Standard Chartered and HSBC each run independent tokenized deposit systems. Swift's ledger connected them as a shared intermediary, rather than through a direct bank-to-bank integration. That routing is the interoperability architecture: a single connection to Swift can in principle serve where a custom bilateral bridge would otherwise be built.
Round-the-clock cross-border settlement is where the banks and Swift say the infrastructure is headed.
