Tokenized deposits could overshadow stablecoins in the digital finance era

The latest debate in the world of cryptocurrency is no longer just "Bitcoin versus altcoins," but is shifting to a more profound question: which will be the dominant currency of the future digital financial system – stablecoins or tokenized deposits?

Reuters cites Megan Greene, a policymaker at the Bank of England, suggesting that the appeal of stablecoins may soon wane, potentially being replaced by tokenized deposits—the digital version of traditional bank deposits. However, the Bank of England's policy direction does not view this as an entirely mutually exclusive competition.

In a speech at City Week 2026, Deputy Governor Sarah Breeden described a vision for a diverse monetary system, where alongside traditional bank deposits, there would exist tokenized deposits, regulated stablecoins, and even central bank digital currencies for the public.

To understand this debate, it is first necessary to clearly distinguish between the two concepts.

According to the International Monetary Fund (IMF), tokenized deposits are digital versions of commercial bank liabilities recorded on access-controlled digital ledgers. They remain bank deposits, subject to regulatory oversight, and exist within the current two-tier monetary system.

Meanwhile, regulated stablecoins are digital assets issued by the private sector, backed by safe assets, and typically designed for broader circulation in the digital environment.

In short, tokenized deposits are "programmable bank deposits," while stablecoins are "private money in the form of digital tokens."

The reason central banks favor tokenized deposits is clear. The IMF suggests that this model could help unify payment, settlement, and liquidity management on a single infrastructure, supporting process automation and reducing data reconciliation costs. However, it also requires better real-time liquidity management capabilities.

The Bank of England goes further by highlighting the risk of users confusing insured bank deposits with bank-issued stablecoins under the same brand. In a letter to CEOs in May 2026, the Prudential Regulation Authority (PRA) stated that it remains concerned about the risk of contagion and loss of confidence in the retail market. Sarah Breeden also emphasized that bank-issued stablecoins would not be covered by deposit insurance like traditional deposits.

This is a significant legal and policy advantage for tokenized deposits.

However, assuming that tokenized deposits will "wipe out" stablecoins is likely an oversimplification.

Sarah Breeden herself noted that in future digital asset markets, a safe private monetary system will likely include both tokenized deposits and regulated stablecoins. The Bank of England is currently preparing to include regulated stablecoins in the Digital Securities Sandbox while finalizing regulations for systemically important stablecoins.

In other words, the current UK direction leans toward a model of coexistence under stricter supervision rather than one side completely replacing the other.

The IMF also warns that using stablecoins as settlement assets may enhance efficiency under normal conditions but could amplify pressure when market confidence declines. Therefore, the deciding factor lies not in the name of the currency, but in its safety design, legal framework, and ability to maintain user trust.

A simple example helps illustrate this.

Imagine a business using a domestic bank to pay salaries, hold deposits, and pay partners. In this case, tokenized deposits are a logical choice because they are merely a digital extension of the currency the business already uses daily. They can be integrated directly into existing internal control systems and settlement processes.

Conversely, in global DeFi applications, where users require collateral, 24/7 continuous trading, and liquidity movement across various platforms, stablecoins have the advantage of being born for the Internet environment and having open circulation capabilities.

This is also how the IMF and the Bank of England envision the differing roles of digital currencies in the future financial ecosystem.

For crypto investors, the key lesson is not to view this debate as an absolute win-lose battle.

What is more important is understanding which needs each type of currency serves.

Tokenized deposits may dominate in banking, corporate treasury management, controlled payments, and the settlement of tokenized assets. Meanwhile, stablecoins are likely to remain dominant in blockchain liquidity, DeFi, cross-border Internet payments, and operational models that do not rely heavily on the traditional banking system.

Investors who understand this division of roles will have a much deeper perspective than those simply trying to find the answer to which side will be the "ultimate winner."

In the digital finance world, the biggest beneficiary may not be a single currency, but the ability to connect and interact seamlessly between many different types of currencies.
