Tokenized Deposits and Stablecoins: The Interoperability Gap
Two developments from the week of 23 June 2026 quietly shifted the conversation on tokenized deposits. Neither involved household names in the usual sense, yet both point toward a structural change in how banks, fintechs, and corporate treasuries will move money. The core tension they expose is this: tokenized deposits are useful but closed; stablecoins are open but carry "singleness of money" concerns. What emerged last week are two credible attempts to fix exactly that.
Why Tokenized Deposits Have a Reach Problem
A stablecoin held in any compliant wallet can be sent to any other wallet on the same blockchain, and increasingly across chains. A tokenized deposit cannot. It only settles between participants of the same deposit network. For a corporate treasurer managing cross-border liquidity, that is a severe constraint, not a minor inconvenience.
Global systemically important banks have been rolling out tokenized deposit products for several years now. For many of them, the early institutional anchor client was Ant International, the operator of Alipay+ and a spinoff from its Chinese parent. Ant has been integrating these bank solutions into its blockchain-based treasury management platform, Whale, which is designed to move money across jurisdictions around the clock.
The suspicion among close observers has been that Whale was already doing something that several stablecoin clearing startups are still aiming for: enabling interoperability across incompatible tokenized deposit implementations. That suspicion found more support last week.
Ant International: Liquidity Into Yield
Ant International announced a new leg of its tokenized deposit strategy. The pooled corporate liquidity sitting in tokenized deposits can now be switched into tokenized money market fund (MMF) shares to earn a higher return, and switched back when needed for payments. This builds on an earlier arrangement with French bank Credit Agricole, which uses the so|cash protocol for tokenized deposits. The latest step brings in CACEIS, the bank's securities services arm, and Amundi, Europe's largest asset manager, which is providing the tokenized fund share class.
The accounting and treasury implications here are non-trivial. A balance that was a deposit in the morning can be a fund unit by afternoon, generating yield, and then revert to a deposit before a payment settles. Finance teams will need to track these intraday reclassifications, and auditors will need to understand whether the fund units qualify as cash equivalents under IFRS or US GAAP. The short-duration, high-liquidity nature of MMFs generally supports that classification, but the tokenized wrapper and instant switching introduce new questions about control and recognition timing.
There is also a structural concern for banks. The more seamlessly corporate cash can be parked in MMFs, the more pressure banks face on deposit balances and net interest income. Tokenized deposits are, in that sense, a service that banks offer while simultaneously enabling capital to flow out of their own balance sheets.
The Hazel Network: Solving Reach Without Sacrificing Settlement
The second development came from Vantage Bank and Custodia Bank, which released a whitepaper for a network they call Hazel. The mechanism is straightforward and worth understanding carefully.
Custodia Bank issues a stablecoin called Avit. When a client on the Hazel network sends funds to a wallet outside the network, the recipient automatically receives Avit rather than a tokenized deposit. When someone outside the network sends Avit to a Hazel participant, the stablecoin converts back to a tokenized deposit on receipt. The conversion happens at the boundary, invisibly to both parties in terms of the payment flow.
This design addresses two problems at once. It gives tokenized deposits the open reach of stablecoins without requiring every counterparty to join a shared bank network. And it addresses the "singleness of money" argument against stablecoins: because Avit is redeemable into a regulated deposit at a chartered bank on receipt, it carries a cleaner equivalence to central bank money than a purely private stablecoin.
The cost structure is also notable. Participation fees reportedly decrease as usage scales, and the network could eventually become revenue-generating for member banks, flipping the usual narrative that interoperability is a cost centre.
Where the Two Stories Converge
The Hazel model becomes substantially more powerful if the stablecoin at the boundary is not a single-bank instrument but a multibank one. Several candidates are already in development: Qivalis in Europe, the Zelle stablecoin in the US (currently scoped to remittances), and Japan's "3 Mega SC", a joint stablecoin being built by MUFG, SMBC, and Mizuho. A tokenized deposit network connected to any of these would have far broader reach than one tethered to a single issuer's stablecoin.
This is where Ant International's regulatory position becomes strategically significant. Ant International holds an EU licence as an e-money token (EMT) issuer under MiCA. That licence means its stablecoins can operate as a regulated bridge between separate tokenized deposit networks operating in different jurisdictions, without requiring bilateral arrangements between each network. For compliance and reporting purposes, transactions flowing through such a bridge would need to be characterised carefully: are they payment transactions, asset transfers, or something else? The answer affects VAT treatment, financial instrument classification, and AML obligations under the EU's Transfer of Funds Regulation.
Firms building or auditing infrastructure at this layer should also be tracking how infrastructure-level blockchain compliance controls are evolving, as explored in our coverage of infrastructure-level blockchain compliance controls being pushed below the smart contract layer by institutions such as UBS and Nethermind. The compliance architecture for tokenized deposits will likely need to operate at a similar depth.
What Finance and Compliance Teams Should Do Now
Neither of these developments requires immediate action for most firms, but they do require attention. The following steps are worth taking before these networks reach wider adoption:
- Review whether your accounting policy for cash and cash equivalents covers intraday switches between tokenized deposits and tokenized MMF units, and document the recognition trigger.
- Assess whether your AML and KYC framework covers transactions that convert at a network boundary from a bank deposit to a stablecoin, or vice versa, since the legal nature of the asset changes even if the economic value does not.
- If your firm operates cross-border through entities in the EU, map whether any tokenized deposit arrangements could fall within MiCA's EMT or asset-referenced token definitions, given Ant International's EMT licence and the potential for EU-licensed stablecoins to bridge networks.
- For crypto-compliance reporting, ensure your crypto compliance reporting framework can handle assets that change classification mid-settlement.
The pace of development in this space means that what reads as a niche infrastructure story today tends to become a standard audit question within 18 to 24 months.

FAQ
A tokenized deposit is a digital representation of a bank deposit, remaining on the issuing bank's balance sheet as a liability and carrying deposit protection where applicable. A stablecoin is typically a separately issued instrument backed by reserves held outside the banking system. The accounting treatment differs: tokenized deposits generally sit closer to cash or bank balances, while stablecoins may require assessment as financial instruments or electronic money under local rules. When the two convert at a network boundary, the reclassification point must be documented.
When a tokenized deposit converts to a stablecoin at the boundary of the Hazel Network, the legal nature of the asset changes even though the economic value is preserved. This conversion may constitute a transfer that triggers Travel Rule obligations under the EU's Transfer of Funds Regulation or equivalent rules in other jurisdictions. Compliance teams should treat the conversion event as a distinct transaction for AML monitoring purposes, not merely a routing mechanism.
MiCA's e-money token category applies to crypto-assets that reference a single fiat currency. Tokenized deposits are generally regulated as banking products under existing EU banking law rather than MiCA, though the boundary is still being clarified by the European Banking Authority. Where a stablecoin is used to bridge between tokenized deposit networks, as in the Ant International scenario, the stablecoin itself may fall under MiCA's EMT rules if it meets the definitional criteria.
This depends on jurisdiction and the specific legal form of each instrument. In many EU member states and the US, switching from a deposit-equivalent into a fund unit is a disposal of the deposit and an acquisition of a new asset, which could trigger a gain or loss calculation. The very short holding periods involved mean gains are likely minimal, but the volume of transactions in an active treasury operation could create significant reporting obligations. Tax advisers should review the frequency and scale of any planned switching before implementation.
A single-bank stablecoin at a network boundary limits reach to counterparties willing to accept that bank's instrument. A multibank stablecoin, backed by multiple regulated institutions, is more likely to be accepted widely, reducing friction for cross-network payments. From a compliance standpoint, multibank stablecoins introduce shared governance questions: which institution is responsible for AML screening, and how are disputes over conversion resolved? These governance structures will need to be assessed as part of any due diligence on networks adopting them.
