Federal Reserve Bank of Dallas economists have cautioned that widespread use of tokenized deposits could meaningfully weaken U.S. banks’ ability to fund long-term loans. In an analysis published August 25, 2026, Rosie Levy and Srini Ramaswamy examined how blockchain-based deposit tokens might alter the traditional frictions that keep customer funds relatively stable.

Tokenized deposits represent ordinary commercial-bank money recorded on a distributed ledger. They enable near-instant settlement and programmable features while remaining inside the regulated banking system and eligible to pay interest. Banks view them as a controlled alternative to third-party stablecoins.

How Instant Settlement Changes Deposit Behavior

The economists focused on maturity transformation—the practice of using short-term or on-demand deposits to finance longer-term loans and securities. Current deposit “stickiness” depends partly on operational frictions that slow the movement of funds between institutions.

Instant settlement removes much of that friction. Depositors seeking higher yields could shift balances almost immediately. Programmable tokens combined with autonomous software agents could automate the process, further shortening the time funds remain at any single bank and increasing sensitivity to interest-rate differences.

Levy and Ramaswamy estimated that “other deposits,” excluding large time deposits, currently support about $5.8 trillion—or roughly 80 percent—of the U.S. banking system’s approximately $7 trillion in long-term interest-rate exposure, measured in 10-year equivalents.

Illustrative Scenarios for Reduced Capacity

The analysis presented two hypothetical scenarios rather than forecasts. A 10 percent rise in the sensitivity of deposit rates to market interest rates could reduce banks’ capacity to hold duration risk by about $700 billion in 10-year-equivalent terms, assuming an average deposit weighted life of four years.

Separately, a 10 percent decline in the weighted average life of deposits could shrink maturity-transformation capacity by approximately $580 billion. These figures quantify potential shifts in risk-bearing capacity and do not translate directly into dollar-for-dollar cuts in loan volumes.

Banks facing more volatile funding might respond by holding larger portfolios of highly liquid assets such as reserves and U.S. Treasury securities. They could also increase reliance on term debt markets. Funding loans with more expensive wholesale liabilities would likely raise the cost of credit for consumers and businesses.

Evidence from Instant Payments Abroad

A 2025 study of Brazil’s Pix instant-payment system offered a partial parallel. Heavier use of the network led Brazilian banks to increase holdings of liquid assets, particularly government bonds, while reducing overall credit intermediation. Remaining loan books also shifted toward higher-risk borrowers as institutions sought to preserve returns.

Industry Moves Toward Shared Networks

Despite the identified risks, major U.S. banks are advancing the infrastructure needed for interoperable tokenized deposits. JPMorgan Chase, Citigroup, Bank of America and Wells Fargo are supporting a shared network developed through The Clearing House, with a target launch around 2027.

Swift has prepared a blockchain ledger for initial use, with 17 banks across six continents lined up for pilots. In parallel, 39 state bankers associations have formed the BankChain Alliance to give smaller institutions a pathway onto shared ledgers. Cross-border tests, including a recent transaction between Standard Chartered and HSBC using Swift’s system, demonstrate growing connectivity.

The Dallas Fed researchers noted that deposit tokens must circulate beyond their issuing bank to gain meaningful scale—precisely the outcome the new consortia aim to achieve. They presented the potential consequences without assessing the probability of broad adoption.

Banks already weighing operational changes have described the risks as familiar in principle but intensified by continuous 24/7 transfer capability. The analysis underscores that any significant shift toward programmable, instantly movable deposits could alter both liquidity management practices and the broader availability of credit.
