Commercial banks have a clear financial lever to fight the deposit drain caused by digital tokens

Commercial banks have a clear financial lever to fight the deposit drain caused by digital tokens: they can simply raise the yields they offer retail savers.

The Looming Six-Trillion-Dollar Shift

That is the core finding of fresh research published by the Bank for International Settlements (BIS). The paper injects new data into an urgent debate over how private stablecoins and tokenized yield products threaten traditional banking funding models.

In January, Bank of America CEO Brian Moynihan issued a stark projection: as much as $6 trillion in deposits could migrate into stablecoins and related yield-bearing alternatives.

Such a massive flight of capital could severely squeeze overall lending capacity and drive up borrowing costs across the entire financial sector.

Behind the Mechanics of Reserve Management

At the heart of this liquidity migration lies the way issuers manage their reserves.

A December Federal Reserve staff analysis outlined the exact plumbing behind the trend. Money placed in stablecoins frequently loops back into the banking system, but it returns in the form of institutional issuer deposits rather than retail savings.

This subtle shift alters the fundamental identity of who supplies banks with funding, even if the total aggregate deposit volume remains constant on paper.

Weighing Liquidity Buffers Against Long-Term Lending

The consequences for financial institutions are structural and immediate.

Larger, uninsured balances compel banks to maintain much heavier buffers of liquid assets. That defensive posture leaves significantly less room for the long-term loans traditionally extended to corporate borrowers.

At the same time, trying to block customer defection by offering higher interest rates directly inflates institutional funding costs.

Lenders May Target Rates to Keep Mobile Depositors

How can lenders survive the squeeze? The Fed analysis suggested banks could selectively target better rates specifically at customers most likely to switch, while quietly maintaining lower yields for less mobile depositors.

Even so, the BIS paper draws cautious boundaries around its own conclusions. It does not establish definitive losses of bank deposits or lending capacity because its sample size covers only a single high-rate episode.

Those outcomes will inevitably shift as yield-bearing stablecoins and tokenized money market funds continue to gain traction.

For now, however, the path forward remains anchored in executive decision-making. “Banks retain measurable influence over the speed of that adoption through strategic deposit pricing,” the BIS authors wrote.
