Tokenization Threatens Deposit Stability, Dallas Fed Researchers Warn

Threats to Long-Term Lending Capacity

The rapid adoption of deposit tokenization and instant settlement technologies could fundamentally alter the traditional banking model, potentially curbing banks’ ability to extend long-term loans while forcing institutions to hold significantly larger cash cushions, according to research published by the Federal Reserve Bank of Dallas.

Authored by Dallas Fed researchers Rosie Levy and Srini Ramaswamy, the report was commissioned to understand how commercial bank deposits built on blockchain architecture could impact core functions of the U.S. banking system. At the heart of commercial banking is “maturity transformation” — the practice of taking short-term, low-cost deposits and using them to fund long-term, fixed-rate assets like mortgages and business loans.

Historically, banks have relied on the relative stability and “stickiness” of customer deposits to manage this duration risk. However, the report suggests that tokenized deposits — which allow near-instantaneous transfers 24/7 across banking networks — could dismantle those traditional frictions. With the emergence of automated yield-switching tools, programmable smart contracts and agentic artificial intelligence, depositors could automatically shift funds to higher-yielding institutions in real time.

This added speed and automation, the report argues, could shorten the effective lifespan of bank deposits and weaken the foundational support for long-term lending. According to calculations provided in the report, roughly 80% of the $7 trillion in aggregate duration risk taken on by U.S. banks is supported by the unique duration characteristics of standard deposits.

The authors estimate that a mere 10% reduction in the weighted average life of deposits would reduce the banking system’s capacity for maturity transformation by approximately $580 billion. Beyond reducing lending capacity, widespread tokenization could trigger heightened liquidity risk during both normal operations and periods of stress.

Higher Liquidity Demands and Outflow Risks

Under current regulatory frameworks, banks are required to maintain a liquidity coverage ratio (LCR) by holding high-quality liquid assets, such as cash and U.S. Treasuries, against potential deposit outflows. Operational deposits currently receive favorable treatment under regulatory stress assumptions due to their historical stickiness.

Therefore, if tokenization increases deposit velocity and volatility, regulators and stress-testing models would likely assign higher assumed outflow probabilities to these balances. To offset these higher projected run-rates, banks would be forced to reallocate capital into lower-yielding liquid assets rather than higher-yielding loans.

However, industry experts contend that the central bank’s analysis overlooks critical structural realities of legal and operational settlement. Chris Turner, co-founder of decentralized impact investment platform Kula, pushed back against the report’s underlying premises. Turner argues that the Dallas Fed oversimplifies the mechanics of blockchain transactions by equating token speed with actual legal claim settlement.

“The speed of a token transfer does not necessarily mean the underlying financial claim settles at the same speed,” Turner noted, highlighting that while a token can traverse a blockchain network in seconds, the underlying payment, ownership right or legal claim remains tied to external infrastructure.

According to Turner, finality and legal rights still depend on traditional intermediaries — including banks, custodians, clearing systems and regulatory registries.

“Tokenization doesn’t mean the whole financial system settles faster,” Turner said. “The token may move instantly, but the underlying claim still depends on traditional registries to complete the settlement. This is where the Dallas Fed’s analysis misses an important piece of the picture.”

While major financial institutions continue exploring tokenized deposits as a regulated alternative to stablecoins, real-world adoption remains in its early stages. As infrastructure like Fednow expands alongside commercial deposit networks, the debate underscores an ongoing challenge for policymakers: balancing the operational efficiencies of instant, programmable value transfer with the prudential safety and sound funding structure of commercial banks.
