Club rails vs open layers: two models for settlement modernization

Strip the branding off every settlement modernization effort of the past five years and two models remain. In one, a defined group of institutions builds a network it owns, governs, and settles on together: a club rail. In the other, an operator builds a network any qualifying institution can join, and reach grows with onboarding rather than ownership: an open rail. The two models are converging on the same promise, instant settlement in digital money, from opposite directions, and the difference between them decides who can reach whom.

The clubs

The club model has an impressive roster. Partior, founded by DBS, J.P. Morgan, and Temasek, has settled commercial bank money across USD, EUR, and SGD since 2023, with atomic, 24/7 payment-versus-payment capability; Deutsche Bank completed its first euro transaction on the network in September 2025. Fnality, owned by more than twenty major financial institutions, settles in balances backed one-for-one at the Bank of England, about as high up the settlement-asset hierarchy as private infrastructure can sit. In June 2026, reports in the Wall Street Journal and elsewhere described the most consequential club yet: JPMorgan, Citi, Bank of America, Wells Fargo, and other US banks planning a shared tokenized deposit network operated by The Clearing House, targeting the first half of 2027. And the Canton Network’s coalition structure, while more open than a classic consortium, still composes membership application by application.

The economics explain the pattern. A club shares build costs, aligns incentives among owners, keeps governance among peers, and keeps the settlement asset inside the regulated two-tier system, which is exactly what central banks prefer. Those are real strengths. The same choices bound the network’s reach to its membership: a club is, by construction, closed to the counterparties who did not join, and every club settles its own asset under its own rules.

The open rails

The open model’s flagbearers today are the regulated stablecoin networks: settlement on public infrastructure in tokens like USDC, with membership bounded by vetting rather than equity. Reach compounds differently here. An open network adds a corridor every time it onboards an institution anywhere, which is why open rails have grown fastest exactly where correspondent coverage is thinnest. The tradeoffs run the other way: the settlement asset is a private token whose par machinery is still debated, the operator anchors the network to its own instrument, and compliance obligations sit with every participant rather than being embedded in a shared membership standard.

Two models, one gap

Put the maps together and the gap is obvious: nothing settles natively across them. A Partior member cannot settle into Fnality; a stablecoin network does not clear into the planned TCH token network; each club and each open rail is a complete world with its own asset, rulebook, and edge. The official-sector answer, the BIS-convened Project Agorá, is testing tokenized central bank and commercial bank money on one platform with eight central banks and over 40 financial institutions, and is explicit that it is not building a finished product. We trace the structural reasons in why settlement networks do not talk to each other; the short version is that fragmentation is not a bug in either model. It is what both models produce when they succeed.

That leaves institutions with liquidity fragmenting across venues and a genuinely hard commitment problem: the clubs carry the biggest balance sheets, the open rails carry the fastest-growing reach, and betting exclusively on either means inheriting its blind spots.

The third model: a layer above both

The alternative to picking a region on the map is a layer that spans it. In that model, each club and each open rail is a rail: something payments route across, chosen per transaction, rather than something an institution must marry.

Where Frame fits

Frame is the settlement layer for modern finance. Through configured integrations, Frame Rules checks the institution's policy before release, and Frame Proof seals the outcome reported by the customer's execution platform.

The customer's platforms execute the transaction. Rail coverage, execution timing and finality depend on the configured integration and the underlying systems. The institution remains responsible for its policies, permissions and operating controls.
