Citi moves tokenised deposits on Swift ledger with FAB and OCBC

Citi has become the first US bank to move client money over Swift's new blockchain infrastructure, settling live cross-border US dollar payments with First Abu Dhabi Bank (FAB) and Oversea-Chinese Banking Corporation (OCBC) in transactions completed on 2 September 2026. The transfers are the first on the Swift ledger in the Middle East and South-East Asia respectively, and they use tokenised deposits to clear funds outside the cut-off times and weekend closures that still govern most correspondent banking.

Two more Singapore lenders, DBS and United Overseas Bank (UOB), are expected to run equivalent USD transactions with Citi later in September. All of it sits inside a controlled proof-of-concept scheduled to run from July to December 2026, so the volumes are small by design. The signal, for finance professionals, is not the size of the trades but the direction of travel: the world's dominant messaging network is now moving value, not just instructions about it.

What did Citi actually do?

Citi processed USD payments on Swift's shared ledger rather than a sandbox simulation. The bank routed the transactions through tokenised deposits, digital representations of commercial bank money that stay on the bank's balance sheet, and settled them without waiting for local business hours to open.

The work builds on infrastructure Citi has been assembling for two years. Its 24/7 USD Clearing solution now serves more than 300 bank clients globally, up from roughly 250 a year earlier, while Citi Token Services has processed around $1 billion since launching in 2024 and is live in the US, UK, Singapore and Hong Kong. Combined with the bank's Citi Custody+ platform, these form the "network of networks" that Citi is now plugging into Swift's ledger.

How does the Swift ledger work?

Swift announced the shared ledger on 29 September 2025 at its Sibos conference in Frankfurt, and built it with ConsenSys on Linea, an Ethereum layer-2 network. The design is EVM-compatible and based on Hyperledger Besu, but access is fully permissioned: only the bank consortium decides who can transact. Swift moved it from concept to live deployment in around nine months, switching it on for 17 banks across six continents on 9 July 2026.

Crucially, the ledger is an orchestration layer, not a settlement replacement. It lets participating banks coordinate bank-issued tokenised deposits, including overnight and at weekends, while final settlement still completes through established systems such as real-time gross settlement (RTGS). Swift positions this as the fix for a specific problem: banks and infrastructures are each building their own blockchains and tokenised deposits, and without a common layer those systems risk becoming digital islands that cannot talk to one another. Swift connects more than 11,000 institutions across 200-plus markets, which is the reach it is betting will make interoperability stick.

Why does an always-on ledger matter for cross-border payments?

Traditional cross-border payments still stall on cut-off times, weekend closures and chains of correspondent banks. For a corporate treasurer, that means value trapped over a US holiday weekend or a payment that cannot be released until a distant market opens. An always-on ledger compresses that delay toward instant, giving beneficiaries faster credit and freeing up liquidity that would otherwise sit idle.

Tokenised deposits are the mechanism. Unlike stablecoins, the underlying funds remain inside the regulated banking system, keep their deposit-insurance treatment and carry the same legal status as any other bank deposit. That distinction is central to why banks, rather than crypto-native issuers, are driving this particular version of the always-on economy.

Where does this sit in the bank-led tokenisation race?

Citi is not alone, and it is not first to scale. JPMorgan's Kinexys platform, formerly JPM Coin, already runs an average of more than $5 billion a day and has handled north of $40 trillion since inception, and it has extended its deposit token onto the public Base network. A separate US initiative led by The Clearing House aims to let multiple banks clear and settle tokenised deposits on shared rails. The competitive logic is consistent across all of them: keep corporate settlement flows on bank balance sheets and blunt the appeal of holding a stablecoin for the same job.

That contest has a regulatory backdrop. The GENIUS Act, signed into law as Public Law 119-27 on 18 July 2025, set a federal framework for payment stablecoins and, notably, affirmed that banks can issue tokenised deposits and use blockchains. With roughly $263 billion of stablecoins now in circulation, banks have both a threat to answer and, for the first time, statutory clarity to answer it.

Citi's Swift transactions are best understood against that backdrop: less a single product launch than positioning for a payments market that is splitting into bank-issued and non-bank digital dollars.

What are the collaborating banks saying?

The partner banks framed the pilots as early but meaningful. OCBC's Carmen Chan, Deputy Head of Global Transaction Banking, described the live transactions with Citi as a step towards moving bank-issued digital money across borders more efficiently, with faster access to funds and greater payment certainty for corporates. UOB's So Lay Hua, Head of Group Transaction Banking, cast the bank's forthcoming USD transaction with Citi as evidence of what industry collaboration can build, leaning on UOB's regional ASEAN network. At DBS, Group COO and Co-Head of Digital Assets Rachel Chew pointed to interoperability and common standards as the precondition for wider adoption of tokenised money.

Why This Matters to FinanceX Readers

For treasurers and financial institutions, the friction being removed here is real money: liquidity stranded over weekends and holidays, and value-dating delays baked into correspondent chains. But read the structure carefully. Settlement still lands on legacy RTGS rails, so this is an upgrade to the plumbing, not a rip-and-replace.

The strategic takeaway for investors is that the largest banks are consolidating around interoperable, bank-issued tokenised deposits as their collective answer to stablecoins, now with regulatory cover from the GENIUS Act. The number to watch is conversion: whether these controlled pilots turn into production volume before the proof-of-concept window closes in December 2026, and whether Swift's ledger becomes the neutral connective layer or just one more island.
