UBS and Ant International Unite on Blockchain Tokenized Deposits to Transform Cross‑Border Payments

On Tuesday, November 18, 2025, the financial world is still digesting one of the most significant bank–fintech tie‑ups of the year: Swiss banking giant UBS and Ant International, the global payments arm of Ant Group, have signed a strategic partnership to bring blockchain-based, tokenized deposits into the heart of cross‑border payments and treasury operations. ^[1]

The agreement centers on Ant International adopting UBS Digital Cash — the bank’s blockchain-powered tokenized deposit platform — and linking it with Ant’s own treasury infrastructure to enable real-time, multi‑currency fund flows across borders. ^[2]

What UBS and Ant International Have Announced

Under a Memorandum of Understanding signed at UBS’s flagship office at 9 Penang Road in Singapore, UBS and Ant International will: ^[3]

Use UBS Digital Cash, a blockchain-based payment platform piloted in 2024, as tokenized bank money for Ant International’s settlements.
Support Ant International’s global treasury operations with real‑time, on‑chain payments that aim to be more efficient, transparent and secure than traditional cross‑border rails.
Co‑develop “joint innovations” in tokenized deposits, connecting UBS Digital Cash with Ant’s in‑house Whaletreasury platform.

The Yahoo Finance coverage of the deal highlights that Ant International will specifically rely on UBS Digital Cash for payment settlement and liquidity management, underlining how central the platform is to the partnership. ^[4]

Senior executives on both sides have framed the collaboration as more than just another fintech experiment. UBS’s Asia-Pacific wealth management leadership called it a step toward a “real‑time, multi‑currency payment solution” that could set new standards for transparency and efficiency, while Ant’s platform technology head emphasized their shared belief that blockchain can fundamentally reshape cross‑border payments. ^[5]

UBS Digital Cash Meets Whale: The Tech Behind the Tie‑Up

A key reason this partnership is attracting global attention is that it connects two mature, institutional-grade blockchain systems:

UBS Digital Cash

UBS Digital Cash is UBS’s tokenized deposit solution — essentially digital Swiss-franc and multi‑currency bank money recorded on a permissioned blockchain, but still fully backed by deposits on the bank’s balance sheet.

In its 2024 pilot, UBS Digital Cash processed both domestic and cross‑border transactions in currencies including CHF, USD, EUR and CNY, demonstrating that programmable, tokenized deposits can work at institutional scale rather than just in sandbox experiments. ^[6]

Unlike public stablecoins, these tokens are:

Issued and redeemed directly by a regulated bank.
Settled on a controlled ledger designed for 24/7 availability and atomic settlement.
Built to fit bank‑grade compliance and risk frameworks.

Ant International’s Whale Platform

On the other side is Whale, Ant International’s internal blockchain-based treasury and settlement engine. Ant began building Whale in 2019; by 2024 more than one‑third of its transaction volume was already being processed on‑chainvia this platform. ^[7]

Whale is already integrated with several banks’ tokenized deposit or deposit-token platforms, including solutions from HSBC, Standard Chartered and DBS, and has been used in pilots for cross‑bank deposit token transfers and real‑time liquidity movements. ^[8]

Connecting UBS Digital Cash with Whale is therefore not a greenfield lab project; it is an attempt to knit together two production‑grade infrastructures into a continuous, programmable treasury network.

Why Tokenized Deposits Matter for Cross‑Border Payments

Traditional cross‑border treasury operations are constrained by:

Cut‑off times in different time zones.
Fragmented local payment systems.
Idle balances trapped in multiple Nostro and operational accounts.

The joint UBS–Ant solution is explicitly designed to address those bottlenecks. According to the press release and related coverage, the connected system aims to: ^[9]

Enable real‑time, multi‑currency fund flows between Ant International entities.
Remove dependence on rigid cut‑off times by settling on‑chain, 24/7.
Improve global liquidity management, letting funds be rebalanced continuously rather than batched in end‑of‑day cycles.
Provide auditable, transparent records of movements for both regulators and corporate treasurers.

Some analysts have described this as an early move toward “programmable global treasury” — where rules about how, when and in which currency liquidity can move are encoded into smart contracts instead of spreadsheets and manual approvals. ^[10]

November 18, 2025: Ant International Doubles Down on Tokenisation

Today’s news cycle doesn’t stop at the UBS deal. Ant International is also in the headlines on November 18, 2025, for its growing role in Hong Kong’s Project Ensemble, the Hong Kong Monetary Authority’s initiative to build a tokenisation and wholesale digital-money ecosystem.

In a separate announcement, Ant International said it has joined Project Ensemble’s Architecture Community, which shapes technical standards for the territory’s tokenisation framework. The company has already helped execute the first HKD‑denominated cross-bank transfer under the project’s new Ensemble^TX pilot environment, again using its Whale platform for real-time liquidity use cases. ^[11]

Taken together, the UBS partnership and the Project Ensemble announcement show that Ant International is positioning itself as:

A major corporate user and shaper of tokenised bank money in multiple jurisdictions.
A bridge between Asian and global banking infrastructures, rather than a player tied to a single domestic system.

For UBS, partnering with such a deeply embedded payments operator gives its digital cash ambitions instant relevance across a vast merchant and wallet network connected through Ant’s Alipay+ ecosystem. ^[12]

A Broader Shift: From Pilot Projects to Institutional Blockchain Infrastructure

The UBS–Ant announcement is landing in a context where traditional financial institutions are rapidly turning pilot projects into live, revenue‑adjacent infrastructure:

DBS and Ant International recently expanded their own partnership, enabling DBS PayLah! users to pay at over 150 million merchants in more than 100 markets via Ant’s Alipay+ network and exploring tokenized deposits for instant remittances. ^[13]
Ant International has used Whale to test and deploy multiple deposit-token systems with HSBC and Standard Chartered, including cross‑bank transfers of millions of Hong Kong dollars as part of real‑world pilots. ^[14]
Commentaries such as finews.asia’s coverage of the UBS deal frame it as part of a shift toward programmable money, real‑time settlement, and capital‑efficient liquidity management in institutional finance, with Asia emerging as a key innovation hub. ^[15]

In this landscape, the UBS–Ant tie‑up is notable for its scale and specificity: it is not about generic blockchain enthusiasm, but about concrete use cases in treasury, settlement, and liquidity that are already mission‑critical for both firms.

What Changes for Corporates, Merchants and Banks?

If the integration between UBS Digital Cash and Whale moves from MoU to production as expected, the impact could be significant for different stakeholders:

Corporate treasurers

Faster sweeps and pooling: Real‑time, multi‑currency transfers between Ant International entities could reduce the need for large buffer balances in each market.
Better FX and risk management: With 24/7 settlement, treasurers can align funds movements more closely with trading or sales cycles.
Richer data: On‑chain settlement trails can feed analytics on liquidity usage, counterparty exposure and intra‑group flows.

Merchants and payment partners

Most end‑users will still see a familiar QR code or checkout button, but under the hood:

Settlement between wallets, acquirers and banks can become near‑instant, even across borders.
Smaller merchants may eventually receive funds faster, which is particularly important for working-capital‑constrained SMEs that Ant International already targets with its Bettr credit tech solutions. ^[16]

Banks and infrastructure providers

For other banks, the message is clear:

Tokenized deposits and deposit tokens are moving from nice‑to‑have pilots to competitive necessities in cross‑border cash management.
Interoperability will be key. Ant International already integrates with multiple banks’ platforms; UBS now joins an ecosystem that also includes HSBC, Standard Chartered and DBS in various capacities. ^[17]

Regulatory and Policy Backdrop

The move toward tokenized bank money is happening alongside a broader regulatory push to bring digital assets under clearer rules.

On November 18, 2025, a new bill introduced in the U.S. Senate seeks to define when crypto assets are securities versus commodities, clarifying the respective roles of the SEC and CFTC. While it does not target tokenized deposits directly, it is part of a global pattern: policymakers are trying to draw bright lines around digital assets just as large institutions roll out new blockchain-based payment systems. ^[18]

For regulators, tokenized deposits like UBS Digital Cash are often seen as a safer, more familiar model than public stablecoins, because they:

Stay firmly within the existing banking‑licence and deposit‑guarantee framework.
Use permissioned infrastructure where access can be controlled and audited.
Can be integrated with existing anti‑money‑laundering and sanctions‑screening processes.

That said, cross‑border use raises complex questions about jurisdiction, data residency, and harmonizing standardsbetween regulators in Switzerland, Singapore, Hong Kong and beyond — one reason initiatives such as Project Ensemble and Singapore’s Project Guardian stress common architectures and shared-ledger concepts. ^[19]

Key Questions Ahead

Despite the momentum, several open questions will shape how transformative the UBS–Ant partnership ultimately becomes:

Interoperability: Will UBS Digital Cash be able to interact seamlessly with other deposit-token systems (HSBC, JPMorgan’s Onyx platforms, etc.), or will corporates need to juggle multiple siloed ledgers? ^[20]
Scalability and resilience: Can tokenized deposit platforms maintain high throughput and uptime while meeting stringent banking risk standards, especially in peak shopping or trading seasons?
Commercial model: How will pricing for on‑chain cross‑border settlement compare with existing SWIFT‑based or correspondent banking fees — and will savings be passed on to merchants and consumers?
Timeline to full production: Today’s announcements are centered on MoUs and pilots; the market will watch closely for hard timelines on live, scaled deployments. ^[21]

Why This Deal Matters Now

The UBS–Ant International collaboration is more than a headline about blockchain buzzwords. It signals that tokenized bank money is rapidly becoming the preferred institutional tool for fixing long‑standing frictions in global payments and liquidity.

On November 18, 2025, the picture that emerges from today’s cluster of announcements is clear:

Ant International is deepening its role as a global hub for tokenised treasury infrastructure, across Singapore and Hong Kong. ^[22]
UBS is using Digital Cash to secure a front‑row seat in the next phase of institutional blockchain, especially in Asia’s fast‑evolving fintech landscape. ^[23]
Regulators are, in parallel, working to define the guardrails for digital assets — increasing the chance that tokenized deposits can scale within a clearer, more predictable framework. ^[24]

For Google News and Discover readers following the intersection of banking, payments and blockchain, this is the story to watch: not just crypto prices or speculative token launches, but how the plumbing of global finance itself is being rebuilt on programmable money.
