Quick Summary

The Siam Commercial Bank has become the first global financial institution to implement 24/7 USD Clearing via Citi Token Services. This blockchain-based solution enables near real-time cross-border payments, allowing institutional clients to bypass traditional banking cut-off times and settle transactions 365 days a year.

How Does Citi Token Services Solve Cross-Border Friction?

Here is how Citi solves settlement delays for global institutional clients. By integrating 24/7 USD Clearing with a private permissioned blockchain, the solution tokenizes deposits within Citi’s regulated network. This allows for instant liquidity movement across different time zones and jurisdictions, even during weekends or public holidays.

  • Eliminates banking cut-offs by operating 24/7/365.
  • Bridges multi-bank environments through a "network of networks" approach.
  • Reduces operational risk by using regulated, tokenized deposits.

What Results Has This Blockchain Integration Delivered?

The partnership has already proven its utility through a successful live transaction involving Phillip Securities Thailand. By leveraging Citi Token Services, funds were moved from London to Thailand over a US holiday weekend, a feat impossible under traditional correspondent banking rails. This always-on payment corridor currently connects over 300 financial institutions across more than 50 global markets.

  • First global implementation of the integrated tokenized clearing solution.
  • Instant settlement achieved across disparate geographic regions.
  • Seamless interoperability between Citi and non-Citi accounts.

How Does This Advance Thailand’s Digital Economy?

The Siam Commercial Bank is positioning itself as a leader in programmable payment capabilities within Southeast Asia. By adopting 24/7 USD Clearing, SCB supports the Bank of Thailand’s vision for a modernized financial system. This infrastructure allows Thai businesses to compete globally by managing USD liquidity efficiently without being tethered to Western business hours.

Thanawatn Kittisuwan, Head of Transaction Banking, The Siam Commercial Bank, said: "At SCB, we continuously invest in innovative capabilities that help our corporate and institutional clients operate more efficiently in an increasingly global and connected business environment. Through our collaboration with Citi, we are the first bank in Thailand to leverage tokenization to enhance cross-border USD capabilities, helping our clients simplify operational constraints and conduct their international business activities with greater flexibility."

FF NEWS TAKE:

This partnership truly moves the needle for institutional finance. While many blockchain projects remain in the pilot phase, Citi and SCB have delivered a live, 24/7 USD Clearing use case that solves the very real problem of weekend liquidity gaps. By successfully bridging tokenized deposits with traditional clearing, they are setting the blueprint for the next generation of global correspondent banking.
