Citi and DBS Execute Instant Tokenized Dollar Transfer via SWIFT Ledger

Citi and DBS successfully processed a tokenized U.S. dollar payment between Singapore and New York on a Saturday, completing the transaction within minutes through SWIFT’s Digital Ledger. The test demonstrates that banks can coordinate tokenized deposit instructions outside regular operating hours.

How the Transaction Worked

The payment used SWIFT’s blockchain‑based ledger to orchestrate the movement of bank‑issued tokenized deposits. While the ledger recorded, sequenced, and validated the payment obligations via smart contracts, the final settlement continued to rely on existing banking infrastructure.

Key Participants and Timeline

• Transaction date: September 5 (Saturday)
• Participating banks: Citi (New York) and DBS (Singapore)
• SWIFT’s initial live‑transaction pilot involved 17 banks across six continents, announced in July 2026.
• Citi previously completed live tests with First Abu Dhabi Bank, OCBC, HSBC, and Standard Chartered.

Implications for Cross‑Border Payments

DBS described the settlement time as “minutes,” compared with the industry norm of up to two business days for similar corridors. The test shows that tokenized deposits—bank liabilities rather than public stablecoins—can be moved quickly while preserving traditional compliance and risk controls.

Future Outlook

Citi plans additional weekend tests with DBS and United Overseas Bank in September and is targeting participation in a U.S. tokenized deposit network slated for 2027. DBS, which launched its own permissioned blockchain token services in 2024, aims to expand the corridor coverage and onboard production customers.

What Remains Unclear

• The transaction value, customer identity, and fee structure were not disclosed.
• SWIFT and the participating banks have not announced a commercial launch date, pricing model, or full production capacity.
