Community banks are defending deposits while the payment flow migrates
An op-ed's deposit data undercuts the ABA's stablecoin fear, but the workflow leak is the one that costs.
A Fortune Crypto op-ed argues community banks have the stablecoin question backwards. The risk the piece names is customers keeping the balance at the bank while moving payments, foreign exchange, merchant services, and treasury management to a platform that collects the transaction data, the fee revenue, and the daily contact, leaving the bank with the funding and none of the relationship built around it.
The deposit-fear case runs on an American Bankers Association warning, citing an April 2025 Treasury Borrowing Advisory Committee estimate, that as much as $6.6 trillion in transactional deposits is theoretically exposed to stablecoin migration, and the association has lobbied Congress to close what it calls a yield loophole in stablecoin rules; the op-ed's rebuttal is that this describes a pool that could move rather than one that has. Community bank deposits grew roughly 26%, about $482 billion, between June 2019 and March 2026, spanning the entire rise of stablecoins, and studies from CRA International and the Council of Economic Advisers found no statistically significant relationship between stablecoin growth and community bank deposit outflows over that period. The piece compares the dynamic to money-market funds and brokered CDs, which out-yielded checking accounts for decades without emptying them, and an April 2025 Better Markets report it cites put banks below $10 billion in assets at roughly $2.5 trillion collectively, a figure that had barely changed in three decades even as the largest banks grew.
That $6.6 trillion reads better as a map than a forecast. Oversight of stablecoins has become a dollar funding problem, as this publication has argued, and the ABA's exposure estimate is, in practice, a list of balance sheets that would absorb the pressure if the outflow ever arrived. Treasury's GENIUS Act rulemaking is where the question gets answered, and it is being answered in definitions and comment periods rather than statute — which issuers face U.S. rules, and whether the yield question the association wants closed is closed at all; that timing is not in the banks' hands, and it is not fast.
Mercury says it serves more than 300,000 businesses and individuals, and the op-ed's observation that a ten-person startup builds its treasury habits on a platform today and becomes a corporate client later is a fair reading of how commercial relationships form. A community bank that spends the next two years litigating yield in Washington and none of it wiring stablecoin acceptance into its own business portal is protecting a balance while the operating account migrates, and the cheaper move is to offer someone else's stablecoin behind the bank's own login, so the payment flow never reaches the outside platform in the first place. The comment docket is where to watch whether Treasury's definitions land before the next cohort of business customers picks a platform.
