Standard Chartered’s note puts a hard number on a risk U.S. banks have been debating quietly: as much as $500 billion in deposits could migrate into stablecoins by 2028. The report’s headline takeaway is that regional banks sit closest to the blast radius because their business models lean heavily on deposits as the engine of profitability.
What makes the warning bite is not crypto price volatility, but basic banking physics. If core deposits leak out, net interest margins get squeezed and the cost of replacing funding rises, turning a slow outflow into a real liquidity and resilience problem.
How Stablecoins Pull on the Deposit Base
The scenario Standard Chartered outlines starts with simple consumer and institutional behavior: stablecoins that act like cash equivalents, or that look like a better “parking place” for money, can draw balances away from checking and savings. That shift matters because deposits are the low-cost funding source banks use to support lending and other interest-earning activity.
Once deposits fall, banks are pushed toward pricier alternatives, particularly wholesale funding, which is typically less sticky and more expensive. In that world, profitability doesn’t just soften at the margins—it resets lower because the funding stack becomes structurally costlier.
The note treats interest-bearing stablecoins as the accelerant that could turn a drift into a run. If issuers introduce yields that look compelling relative to bank accounts, withdrawal pressure could intensify quickly and create sharper deposit runoff.
There’s also a second-order risk that sits with the banks on the other side of stablecoin plumbing. If issuers pull reserves during stress, the correspondent banks holding those reserves could feel a sudden liquidity shock, amplifying disintermediation at exactly the wrong time.
Why Regional Banks Are More Exposed
Regional banks, in Standard Chartered’s framing, are vulnerable because they’re typically more dependent on net interest income and less buffered by diversified fee businesses. When deposits shrink, NIM compression forces uncomfortable choices—pay up for replacement funding or sell assets—either of which can erode earnings power and tighten liquidity headroom.
The report also calls out concentration risk in issuer banking relationships as a system-level issue. If a small number of banks hold the bulk of reserves for major stablecoin issuers, distress at any one intermediary can transmit quickly through funding channels.
Standard Chartered argues deposits tied to stablecoin activity may behave differently under stress, closer to short-term unsecured liabilities than traditional “core” deposits. If runoff rates rise and deposit spreads weaken, banks can lose both stability and pricing power at the same time.
And the pressure may not stop at funding. The report warns stablecoins could chip away at fee lines like correspondent banking and foreign exchange by offering faster, lower-cost cross-border settlement, removing a diversification cushion for banks already exposed on NIM.
The market’s next step is to watch whether the 2028 migration thesis becomes reality and how quickly the ecosystem adapts. Banks will be judged on liquidity contingency plans, concentration management, and sensitivity to funding costs, while issuers and custodial partners will face growing expectations to disclose reserve placement and redemption mechanics as supervisors track run-risk links.
