Stablecoins vs. Tokenized Deposits: Who Will Control the Future of Programmable Money?
The latest BIS warning about stablecoins is not simply a criticism of crypto. It exposes a much larger contest over how money, banking and financial infrastructure will function when value moves onto programmable blockchains.
The most consequential question raised by the latest stablecoin debate is not whether stablecoins work. They clearly do in many contexts, and their adoption has already demonstrated that blockchain-based representations of dollars can operate at global scale. The more difficult question is what happens when private digital money begins to compete with the monetary architecture built around commercial banks and central banks.
That question moved into the institutional spotlight on August 28, when Bank for International Settlements General Manager Pablo Hernández de Cos argued at the Jackson Hole Economic Symposium that stablecoins, in their current form, do not yet satisfy the fundamental properties required of money at scale. His alternative is not a rejection of blockchain. It is a preference for tokenized deposits, supported by central-bank money and integrated into the existing two-tier monetary system.
The significance of that argument extends well beyond one BIS speech. At almost the same moment, central-bank officials were discussing how reserves themselves could move onto distributed ledgers, while commercial banks were reconsidering whether they should issue stablecoins rather than allow non-bank companies to dominate the emerging market.
For W3Rooster, this makes the story less about a disagreement over one cryptocurrency category and more about a fundamental transition: blockchain may be moving from a challenge to traditional finance toward becoming the infrastructure on which traditional finance is rebuilt.
The BIS Is Questioning the Architecture, Not Just the Token
The BIS argument begins with a deceptively simple idea: money is more than a technological object.
Modern monetary systems work because people generally accept different forms of money as equivalent. A commercial-bank deposit, for example, is normally treated as interchangeable with another dollar deposit and ultimately convertible into central-bank money at par. That property is sometimes described as the “singleness” of money.
Stablecoins introduce a different structure. Multiple issuers can create different tokens representing the same national currency, but those tokens can trade on separate networks and may not always exchange at exactly one-to-one value, particularly during periods of stress. The BIS therefore argues that the architecture underneath a stablecoin matters just as much as the reserve assets backing it.
This distinction is crucial. A digital token can represent one dollar without necessarily functioning like one dollar within the broader monetary system.
The philosophical problem is almost older than finance itself. Money works partly because users do not need to investigate its history before accepting it. Once every payment requires confidence in a particular issuer, reserve structure, blockchain and redemption mechanism, the apparent simplicity of money begins to fragment.
Stablecoins and Tokenized Deposits Represent Two Different Futures
Both stablecoins and tokenized deposits use blockchain technology to make financial claims programmable and transferable across digital infrastructure. Their institutional foundations, however, are substantially different.
A stablecoin is generally a privately issued digital claim designed to maintain a reference value, often against the U.S. dollar. A tokenized deposit, by contrast, represents a conventional bank deposit in tokenized form. The distinction means that tokenized deposits can remain connected to commercial-bank balance sheets and central-bank settlement infrastructure.
The BIS therefore sees tokenized deposits as a way to modernize money without completely redesigning the monetary system. Instead of replacing the banking architecture, blockchain would become another layer through which that architecture operates.
This is one of the most important distinctions for understanding where institutional blockchain adoption may be heading. The debate is not necessarily between “old finance” and “crypto finance.” It is increasingly a debate over whether blockchain should create an alternative monetary system or provide new rails for the existing one.
The Three Tests That Could Define Digital Money
The BIS framework is particularly useful because it gives the stablecoin debate a set of institutional tests rather than relying on adoption statistics alone. The first is singleness: can different monetary claims reliably maintain their equivalence at par?
The second is elasticity: can liquidity expand when the economy requires it and remain available during periods of stress? The third is integrity: can the system maintain effective safeguards against illicit activity while preserving the reliability of financial transactions?
These concepts turn the discussion away from whether a blockchain is fast or whether a stablecoin has billions of dollars in circulation. They ask a more demanding question: can the instrument perform the economic functions that society expects money to perform?
That framework also explains why the BIS is not dismissing tokenization itself. Its August speech explicitly recognizes the potential of distributed ledgers for programmability, atomic settlement and around-the-clock operations. The concern is whether those technological gains can be achieved without weakening the institutional mechanisms that make money trustworthy.
The Hidden Cost: What Happens to Bank Funding?
One of the strongest analytical dimensions of the debate is the effect stablecoins could have on commercial banks. Banks do not simply store deposits. Deposits form an important part of the funding base through which banks provide credit to households and businesses. If significant amounts of conventional deposits migrated into stablecoins, the consequences could extend beyond payments and into the economics of lending.
The BIS argues that the composition of stablecoin reserves matters. If issuers primarily hold bank deposits, those deposits could become more concentrated and potentially more sensitive to changes in market conditions. If issuers instead accumulate government securities, banks could lose some of their traditional role in holding liquid assets. Either scenario changes the relationship between digital money, bank funding and credit creation.
This is why the question “Are stablecoins efficient?” is incomplete. A better question is: efficient for whom, and at whose expense? A payment system can become faster while simultaneously changing who earns the intermediation revenue, who provides liquidity and who ultimately absorbs financial stress. That is the kind of second-order consequence that tends to matter more over a decade than the headline transaction-speed improvements that initially attract attention.
Banks Are Beginning to Challenge the Stablecoin Critique Themselves
There is an intriguing contradiction emerging in the banking industry. For years, many traditional institutions favored tokenized deposits because they preserve the connection between digital money and regulated banking. Yet recent reporting indicates that major banks are now exploring stablecoin issuance as non-bank companies and financial technology firms move deeper into digital payments. JPMorgan, for example, is considering a stablecoin alongside its existing JPM Coin tokenized-deposit infrastructure. A broader group of banks is also exploring stablecoin initiatives.
This does not necessarily invalidate the BIS argument. It reveals a different pressure: even if banks believe tokenized deposits are institutionally superior, they may still feel compelled to participate in stablecoins because customers, competitors and payment networks are moving in that direction.
That creates a strategic paradox. The technology that banks once viewed primarily as a potential threat may become something they need to adopt simply to defend their position within the financial system.
Central Banks Are Moving Onto the Same Rails
The most important development surrounding the stablecoin debate may actually be happening on the other side of the monetary system.
On August 27, ECB Executive Board member Isabel Schnabel argued that central banks should bring reserves onto blockchain-based infrastructure. The ECB has been exploring this through initiatives including Projects Pontes and Appia, with the broader objective of allowing tokenized financial markets to interact more effectively with central-bank money.
This changes the traditional narrative around blockchain. For much of crypto’s history, the conceptual battle was framed as decentralized finance versus centralized finance. But institutional adoption is creating a third possibility: centralized institutions using decentralized or distributed technology to modernize centralized financial functions.
If commercial-bank deposits become tokenized and central-bank reserves become available on compatible ledgers, the most consequential blockchain development may not be the replacement of banks at all. It may be the migration of banks, central banks and financial markets onto programmable infrastructure.
The Interoperability Problem Could Become the Next Battleground
There is, however, a significant obstacle. A tokenized financial system cannot reach its full potential if every institution creates an isolated digital environment. Stablecoins can exist across different blockchains, banks can develop permissioned networks, and central banks can build their own settlement infrastructure. Without interoperability, tokenization risks reproducing the fragmentation it was supposed to eliminate.
The BIS itself identifies interoperability, governance, legal certainty and operational resilience as major challenges for tokenized deposits. Its argument is therefore more nuanced than simply replacing stablecoins with bank-issued tokens: the alternative monetary architecture also needs common standards and mechanisms for moving value safely between networks.
This could ultimately prove more important than the competition between individual tokens. The dominant infrastructure may be the system that allows different forms of digital money to interact without forcing users to understand the underlying complexity. In other words, the future winner may not be the best token. It may be the best connection between tokens.
The Dollar Dimension Makes the Debate Geopolitical
Stablecoins also raise a question that cannot be answered purely through technology or banking theory: who controls the monetary influence of a digital currency?
Dollar-denominated stablecoins can extend access to the U.S. dollar beyond traditional banking channels. For the United States, that can potentially reinforce the international reach of dollar-based financial infrastructure. For countries with weaker currencies, however, widespread adoption of foreign-currency stablecoins could increase the risk of digital dollarization and weaken domestic monetary control. The BIS explicitly identifies monetary sovereignty as one of the concerns surrounding large-scale foreign-currency stablecoin adoption.
This creates an unusual strategic divergence. A development that may look like a threat to monetary sovereignty from one country’s perspective can look like an expansion of monetary influence from another’s. That tension is likely to become more significant as stablecoins become embedded in cross-border payments rather than remaining primarily associated with crypto markets.
Stablecoins Do Not Have to Disappear to Lose the Monetary Debate
The strongest interpretation of the BIS position is not that stablecoins have no future. The institution itself leaves room for stablecoins to serve specialized purposes, including applications connected to decentralized financial markets, provided appropriate safeguards exist.
That distinction matters. Stablecoins can be highly useful without becoming the dominant form of everyday money. They may function as a bridge between traditional currencies and blockchain-based markets, as settlement instruments within specific digital ecosystems, or as specialized collateral and liquidity tools.
This could produce a monetary landscape that is more pluralistic than either side of the debate currently suggests: tokenized deposits for mainstream payments, central-bank money as the ultimate settlement anchor, and stablecoins serving particular digital markets.
Such an outcome would not represent the victory of crypto over banking or banking over crypto. It would represent their convergence under different institutional rules.
The Real Question Is Who Controls Programmable Money
The most durable conclusion from the latest stablecoin debate is therefore not that one model has already won. It is that the boundaries between money, payments and financial infrastructure are being redrawn.
Stablecoins brought private programmable money into the financial mainstream. Tokenized deposits offer banks a way to place existing monetary claims onto blockchain rails. Central banks are now examining how their own reserves can operate within tokenized markets. Meanwhile, banking groups are building blockchain networks designed to preserve their role in the next generation of payments. The BankChain Alliance, announced by 39 state bankers’ associations on August 25, is one example: its planned industry-owned network is intended to support tokenized deposits, stablecoins and automated settlement, with a targeted 2027 launch.
The result is a far more complicated future than the old “crypto versus banks” narrative suggests. The question for the next decade may be less about whether money becomes digital—it already is—and more about who establishes the rules governing programmable money.
That is where the stablecoin debate becomes genuinely consequential. Technology can determine how quickly value moves, but institutions determine what that value represents, who can issue it, how it can be redeemed and what happens when confidence disappears.
For W3Rooster, that distinction is the most useful lens through which to understand the current transition. The future of blockchain finance may not arrive as a dramatic replacement of the existing monetary system. It may emerge more quietly, as banks, central banks and private issuers progressively rebuild the financial system on programmable rails.
The irony is that blockchain’s greatest institutional victory could eventually be its least revolutionary-looking one: not replacing the architecture of money, but becoming the infrastructure beneath it.
