Traditional banking has a well-documented allergy to weekends. Cross-border payments historically grind to a halt when New York closes on Friday, leaving corporates and financial institutions waiting until Monday morning to move money across time zones. Siam Commercial Bank just made that problem someone else’s headache.
SCB has become the first financial institution globally to implement Citi’s combined 24/7 USD Clearing and Citi Token Services solution, a milestone that went live around July 9, 2026. To underline the point with maximum drama, the first live transaction ran during the U.S. July 4 holiday weekend, moving funds from a Citi account in London to an SCB account in Thailand at a time when most of traditional banking was out of office.
What the technology actually does
Here is the plain-English version of what is happening under the hood. Citi Token Services tokenizes deposits on a private, permissioned blockchain, meaning the funds exist as digital representations within Citi’s own regulated network rather than on a public chain like Ethereum or Bitcoin’s ledger.
The infrastructure connects more than 300 financial institutions across more than 50 markets. Citi’s global payments division already moves roughly $6 trillion daily through its pipes, and tokenized deposit transfers within that system average close to $1 billion per day.
