Stablecoins vs. Tokenized Deposits: Who Will Control Digital Money?

For years, the stablecoin debate was framed as a question of whether crypto could reinvent payments.

That question is becoming outdated.

The more consequential question now is who gets to issue and control the digital money moving across blockchain networks.

Banks have an obvious answer: put deposits onchain.

Stablecoin issuers have another: create digital dollars that can move beyond the balance sheet and customer network of any single bank.

The distinction sounds technical. It is not. It determines where liquidity sits, who controls the customer relationship and how money moves through the digital economy.

Tokenized deposits digitize bank money. Stablecoins make digital money portable beyond the bank that issued it.

And in 2026, that competition is moving from theory into financial infrastructure.

Banks Are Now Building the Alternative to Stablecoins

The clearest evidence is coming from the banks themselves.

In June, JPMorgan, Bank of America, Citi, Wells Fargo and other major financial institutions announced a bank-led initiative through The Clearing House to support onchain clearing and settlement of tokenized commercial bank deposits.

The proposed infrastructure is designed to allow tokenized deposits to move between banks while connecting blockchain activity with existing payment systems such as RTP and CHIPS. The target is 24/7 settlement without abandoning the regulated banking framework.

Unlock Blockchain reported in June that the participating U.S. banks were targeting a shared tokenized-deposit network for 2027. The significance goes beyond another blockchain initiative.

Banks are trying to give commercial bank money some of the characteristics that made stablecoins attractive — programmability, continuous settlement and digital transfer — without moving the underlying deposits outside the banking system.

That creates an obvious economic incentive.

Deposits are a core source of bank funding. If customers can get blockchain-based functionality without converting their bank deposits into stablecoins, banks have less reason to lose that relationship.

The Difference Is the Balance Sheet

Consider a corporate treasury holding $10 million at Bank A.

With a tokenized deposit, the money remains a Bank A deposit. The blockchain changes how the claim is represented and transferred, but Bank A still owes the depositor the money and the deposit remains part of its balance sheet.

A stablecoin works differently.

The issuer creates a token backed by reserves such as cash, Treasury bills or other permitted assets. Once issued, that token can potentially move between wallets and counterparties that do not maintain a direct banking relationship with the issuer.

That is the crucial distinction.

A tokenized deposit asks: How do we put bank money onchain?

A stablecoin asks: How do we make digital money portable across institutions?

The technology may look similar. The monetary architecture is not.

But Stablecoins Have One Advantage Banks Cannot Ignore

Stablecoins have a structural advantage banks cannot easily reproduce individually: network portability.

A company holding USDC does not need a direct Circle banking relationship for every transaction. Its counterparty can receive the token through compatible infrastructure, allowing the asset to move across wallets and platforms.

That gives stablecoins something traditional deposits generally lack: a form of digital money whose usability can travel with the token rather than remaining tightly attached to a particular bank account relationship.

The scale is increasingly difficult to ignore.

The BIS estimated stablecoin market capitalization at around $320 billion at the end of May 2026. It also estimated roughly $28 trillion in stablecoin transaction volume during 2025, while warning that much of that activity remained connected to crypto markets rather than the real economy.

The caveat is important: $28 trillion should not be interpreted as $28 trillion of real-world payments.

But the network effect is still significant.

Circle's second-quarter results provide another measure of that growth. USDC circulation reached $73.3 billion, up 19% year over year, while onchain transaction volume increased 151%.

Stablecoins are not gaining traction because they offer a fundamentally different definition of money.

They are gaining traction because a token can travel.

That becomes particularly relevant for cross-border payments and dollar liquidity in markets where access to the U.S. dollar through traditional banking channels is costly or restricted.

A July BIS working paper examining stablecoin dollarization found that stablecoins can provide easy access to U.S. dollar liquidity and examined their interaction with conventional foreign-currency deposits and monetary control.

A bank can tokenize a deposit.

But if the user wants dollar liquidity that can move globally without joining the issuer's banking network, a stablecoin has an inherent advantage.

The Banks' Problem Is Now Interoperability

This is why individual bank deposit tokens are not enough.

JPMorgan already operates deposit-token infrastructure through its Blockchain Deposit Account framework, designed to turn bank deposits into programmable, always-on digital money.

But consider a transaction where the payer uses JPMorgan, the recipient banks with Citi, the asset sits on another blockchain and settlement occurs in another currency.

That is no longer simply a tokenization problem.

It is an interoperability problem.

The significance of the U.S. bank initiative is therefore that institutions are attempting to solve that problem collectively.

The objective is not merely to put deposits onchain. It is to make bank-issued digital money portable between banks.

That is the feature stablecoins already possess.

This Is Ultimately a Funding Fight

The competition also has consequences far beyond payments.

Deposits fund banks.

If customers move money from bank deposits into stablecoins at scale, the money does not disappear. But the economic relationship changes.

Stablecoin issuers generally hold reserves in assets such as Treasury bills and bank deposits rather than using customer balances in the same way commercial banks use deposits to support lending.

The BIS has warned that widespread stablecoin adoption could therefore affect bank funding, credit creation and financial stability.

The potential scale explains why banks are paying attention.

Standard Chartered estimated earlier this year that stablecoins could pull as much as $500 billion in deposits from U.S. banks by 2028 under certain adoption scenarios.

Banks consequently have two reasons to respond.

They want the efficiency of blockchain-based payments.

And they want to keep the underlying money economically attached to the banking system.

Tokenized deposits offer a way to pursue both.

Stablecoins Are Becoming Institutional Infrastructure Anyway

The emerging market is more complicated than a choice between two competing models.

Banks are increasingly integrating stablecoins themselves.

Mastercard is expanding stablecoin settlement infrastructure to support 24/7 processing across multiple regulated stablecoins and blockchain networks.

Standard Chartered and Circle have also launched institutional USDC minting and redemption infrastructure, allowing clients to access USDC through the bank's onboarding process rather than maintaining a direct Circle relationship.

That is revealing.

A major bank is not necessarily telling customers to choose between bank deposits and stablecoins.

It can become the gateway into the stablecoin network.

This suggests that the future financial architecture may involve banks issuing tokenized deposits, distributing stablecoins and providing the regulated infrastructure through which both move.

The BIS Is Pointing Toward a Third Model

The Bank for International Settlements' 2026 Annual Economic Report offers a broader perspective.

Rather than treating tokenization as a replacement for the existing monetary system, the BIS has argued for bringing tokenized assets into the existing two-tier structure of commercial bank money and central bank money.

Its Project Agorá provides a practical example.

The project demonstrated how tokenized commercial bank deposits could be combined with tokenized central bank reserves on a shared platform to enable atomic, multi-currency settlement.

That points toward a third possibility.

The future may not be stablecoins replacing banks.

Nor may it be banks simply copying stablecoins.

It could be a system in which commercial bank deposits, stablecoins and central bank money become interoperable forms of programmable money, each serving different functions.

A February 2026 Federal Reserve Bank of New York Staff Report supports that more nuanced view. Its analysis found that the welfare effects of tokenized deposits and stablecoins depend on factors including regulation, bank risk-taking and how the two forms of money interact. Under some conditions, tokenized deposits are preferable; under others, stablecoins are; and in an intermediate scenario, allowing both to compete can be optimal.

The Real Competition Is Over the Network

That may be the most important shift in the debate.

The question is no longer simply which is better: tokenized deposits or stablecoins. It is where digital money derives its trust, and how freely it can move.

Tokenized deposits preserve the banking relationship and the bank's balance sheet. Stablecoins offer portability beyond a single bank's customer network. Neither side can easily reproduce the other's core advantage.

That makes interoperability the strategic battleground.

A tokenized deposit confined to one bank's ecosystem is useful. A stablecoin accepted across thousands of counterparties is more portable.

But a tokenized deposit that can move between banks, settle against central bank money, interact with tokenized securities and connect to existing payment rails could fundamentally change the equation.

That is what initiatives such as Project Agorá and the emerging bank-led deposit networks are beginning to test.

The future, then, may not be stablecoins replacing deposits or deposits replacing stablecoins.

It may be different forms of digital money competing — and eventually interoperating — across the same programmable financial infrastructure.

The fight is no longer simply over the token. It is over who controls the network through which digital money moves.
