Standard Chartered projected in January that stablecoins could divert approximately $500 billion from US bank deposits by the close of 2028.
Regional banks appeared particularly vulnerable due to their heavy reliance on the interest rate spread between what they pay depositors and what they earn on loans.
Now, 21 major financial institutions, including Bank of America, Citi, Goldman Sachs, and Wells Fargo, committed on Sept. 1 to construct one.
The consortium announced plans to establish a formal company in the second half of 2026, introduce a US dollar-denominated stablecoin in the first half of 2027, and ensure compliance with both the GENIUS Act and MiCA.
The initiative originated as a 10-bank exploration into reserve-backed digital currency in October 2025 and has since expanded to 21 institutions spanning North America, Europe, Asia, Africa, and the Middle East.
Its stated use cases encompass wholesale and institutional transactions, cross-border payments, digital-asset settlement, and retail markets where client advantages can be realized.
| Earlier bank concern | Sept. 1 bank response |
|---|---|
| Stablecoins could pull deposits out of banks | 21 institutions committed to launch a bank-backed stablecoin |
| Regional banks could be exposed to funding pressure | Large banks are positioning to capture stablecoin flows |
| Crypto platforms could compete for customer cash | Banks are creating their own digital-dollar product |
| Stablecoins could redirect reserves into Treasuries | Banks may seek a role in reserve management and distribution |
| Payments could move outside bank rails | Banks want stablecoins for cross-border payments, settlement, and institutional activity |
Why deposits and stablecoins compete for the same dollar
Bank deposits fund lending and balance-sheet activity, with banks earning income on the spread between what they pay depositors and what they collect on loans.
Stablecoins function as fully backed tokens holding reserves in cash, bank balances, and short-dated government securities, with Treasuries comprising the majority of Tether and Circle’s reserve holdings.
A dollar moving from a bank account into a stablecoin remains a dollar in every practical sense while changing who controls the customer relationship, the reserve economics, and the payment rail underneath it.
That shift in control reflects the concern Standard Chartered’s warning addressed.
Owning the stablecoin migration beats losing the relationship
A bank-backed stablecoin customer transferring funds from a traditional deposit into a fully reserved token still diminishes the bank’s conventional funding base.
What a bank-issued stablecoin can preserve is everything built around that deposit: the distribution relationship, the compliance layer, the settlement business, and a share of the reserve economics.
Banks appear willing to accept cannibalization of one portion of their existing model to avoid surrendering the entire customer relationship to a crypto-native competitor.
Total stablecoin market capitalization stands near $303.7 billion, according to DefiLlama, with Tether’s USDT alone representing more than 60%.
Citi’s 2030 research projects a base case of $1.9 trillion in stablecoin issuance and a bull case of $4 trillion, implying roughly $1.6 trillion to $3.7 trillion of additional issuance from current levels.
Citi’s base case also estimates annual stablecoin transaction activity near $100 trillion at 50 times velocity, climbing toward $200 trillion under its bull scenario.
The consortium is positioning for a share of that future issuance and transaction flow, a substantially larger opportunity than any slice of Tether and Circle’s existing balances.
The bank that produced one of the industry’s most aggressive stablecoin growth forecasts is simultaneously helping construct a company designed to compete within that forecast, treating its own projection as a live market opportunity worth pursuing.
| Metric | Estimate | What it means |
|---|---|---|
| Potential US bank deposit outflow | $500B by end-2028 | Stablecoins could pressure traditional bank funding |
| Current stablecoin market cap | ~$303.7B | The market banks are entering today |
| Citi 2030 base case | $1.9T | Roughly $1.6T of additional issuance from today |
| Citi 2030 bull case | $4T | Roughly $3.7T of additional issuance from today |
| Citi base-case transaction activity | ~$100T/year | Stablecoins become payment and settlement infrastructure |
| Citi bull-case transaction activity | ~$200T/year | The market becomes too large for banks to ignore |
Multiple forms of digital money can coexist
None of this signals that banks are abandoning tokenized deposits for public-chain stablecoins. Citi’s research explicitly anticipates stablecoins, tokenized deposits, deposit tokens, and central bank digital currencies coexisting, projecting that bank-token transaction volume could exceed stablecoin turnover by 2030 even as stablecoin issuance itself continues expanding.
The more accurate interpretation is that banks want exposure across every plausible form of digital dollar simultaneously. Qivalis, a separate 37-institution consortium building a euro-pegged stablecoin, demonstrates that the competitive landscape is already dividing by currency and structure as well as by issuer.
The GENIUS Act takes effect on the earlier of 18 months after its July 2025 enactment, which falls on Jan. 18, 2027, or 120 days after federal regulators finalize implementing rules.
The consortium’s first-half 2027 target aligns with that threshold. The same law that provided existing stablecoin issuers with regulatory certainty also opened a clear, compliant pathway for heavily regulated banks to enter the category directly.
That transforms a compliance milestone for incumbents into a competitive entry point for their newest rivals.
One warning indicator for bank-issued stablecoins is Société Générale’s dollar-backed token, which had just $12.5 million in circulation.
Distribution remains the harder test
Institutional trust and compliance infrastructure do not, by themselves, generate the minting volume, secondary-market liquidity, exchange listings, wallet support, and merchant demand that make a stablecoin useful.
Tether and Circle spent years building that kind of distribution, and a consortium of banks cannot replicate it by announcement alone.
Whether the bet pays off or produces a compliant token nobody needs
The bull case has stablecoins approaching Citi’s $4 trillion scenario, with bank-backed tokens becoming one of several dominant digital-money formats used across payments, treasury, and settlement.
Under that path, deposit substitution evolves into a genuine structural funding issue for banks that remained on the sidelines. Institutions in the consortium capture settlement fees, custody relationships, and reserve income in a market many times larger than today’s.
| Scenario | What happens | Who wins | What it means for banks |
|---|---|---|---|
| Bull case: bank stablecoins scale | Stablecoins approach Citi’s $4T scenario and bank-backed tokens gain institutional usage | Consortium banks, regulated issuers, institutional clients | Banks cannibalize some deposits but retain settlement, custody, and customer relationships |
| Base case: partial adoption | Bank tokens find use in wholesale, cross-border, and institutional settlement but do not displace USDT/USDC broadly | Banks in specific niches; crypto-native issuers in public markets | Banks capture some future flows without fully reshaping deposit funding |
| Bear case: compliant but unused | The consortium launches a well-regulated token that fails to build liquidity or integrations | Existing stablecoins and tokenized-deposit systems | Banks spend years building infrastructure customers do not need |
| Regulatory shock case | Stablecoin rules tighten after a failure, run, or liquidity event | Tokenized deposits and bank-controlled rails | Stablecoins lose momentum, and banks pivot harder toward deposit tokens |
The bear case has the consortium building a fully compliant, well-capitalized stablecoin that fails to attract liquidity, mirroring the same pattern Société Générale’s token already demonstrates.
In that scenario, deposit strain remains limited because stablecoins never scale far past their current niche. The 21 institutions end up having spent years and substantial capital building infrastructure that crypto-native issuers and tokenized-deposit systems continue to outcompete on usage.
Banks spent months warning that stablecoins could hollow out part of their business. Their answer was to ensure that if the dollar continues moving onto programmable rails, some of the largest banking names control the rails it moves on.
