Thirty banks would rather issue a deposit than hold a stablecoin

What happened

Cari said on 2 September that it had raised $32.5m in the first tranche of its initial external funding round, 'with the investment coming entirely from banks'. The investors are all six of its Design Partner Banks, First Horizon, Huntington, KeyBank, M&T, Old National and SouthState, together with others including Glacier Bank; Keefe, Bruyette & Woods advised. The network has grown to 'more than 30 institutions, with more than 40 in active discussions to join, altogether representing a total network and pipeline of institutions with more than $10 trillion in combined assets'. The build reached a minimum viable product on 31 March and a full product suite on 31 July, with 'the programmatic capabilities, front-end wallet interface, and operational portal needed to enable banks participating in the pilot to complete the mint, transfer, and burn cycle for a tokenized deposit'. Gene Ludwig, the founder and chief executive and, on the company's own account, the 27th Comptroller of the Currency, said 'There is no stronger endorsement of what we are building than having the banks we are building it with choose to invest alongside us.' Five bank executives are quoted and they say the same thing in different words: Bryan Jordan of First Horizon that the shared infrastructure 'gives us access to capabilities that would be difficult and costly to develop independently, while allowing us to continue competing on the relationships and service that differentiate First Horizon', and Eric Girard of KeyBank that shared infrastructure is a way of 'keeping money within the regulated banking system and the protections our customers rely on'. The ledger is Matter Labs' Prividium, chosen in March, which Cari describes as permissioned and privacy-preserving and anchored to Ethereum; that release states the structural claim plainly, that 'deposits represented by Cari tokens remain regulated bank liabilities held on participating banks' balance sheets and subject to existing oversight and FDIC insurance', and carries an endorsement from the Mid-Size Bank Coalition of America.

Why it matters

Two ways of putting a dollar on a chain were funded in the same week and they are not variations on each other. On 1 September twenty-one of the largest financial institutions in the world committed to a company that would support the issuance of a stablecoin, a claim on a reserve pool held by a new entity. Here, thirty-odd regional and community banks are paying to build the other one, in which the token is a receipt for a deposit that never leaves the issuing bank's balance sheet and never leaves deposit insurance. The distinction is the whole of the case: a stablecoin moves funding out of the banking system, a tokenized deposit does not, which is why the banks most exposed to deposit flight are the ones writing the cheques. The ownership structure says the same thing again. The first outside capital comes entirely from the customers, which is the model Ludwig already built once at Promontory Interfinancial, a network of roughly 3,000 member banks that solved a different deposit problem by pooling the same sort of institution. What is being bought is not a product but a position: a shared rail that regional banks control, rather than one a large bank or a stablecoin issuer would sell them access to.

What is not settled

Nothing has gone into production. The network is in pilot, the March release put broader rollout at 'later in 2026' and neither release read here gives a launch date, a transaction volume, a live interbank movement or a fee. The $10tn is the combined assets of the banks in the network and the pipeline together, not deposits on the network, and the release does not separate the thirty who have joined from the forty in discussion. It gives no valuation, no size for the second tranche and no target for the round. The harder question is settlement. A tokenized deposit issued by First Horizon and one issued by KeyBank are claims on different banks, and neither release read here says what asset settles a transfer between them or whether the tokens exchange at par across the network, which is precisely the singleness objection the Bank for International Settlements put to stablecoins at Jackson Hole a week earlier.
