Every generation of market infrastructure gets built to fix trapped liquidity, only to move the trap somewhere else. Public chains deliver mobility, but lack privacy. Private chains deliver privacy, but trap liquidity inside vertical silos. Our new whitepaper argues that liquidity mobility is the primary frame for evaluating the next generation of settlement infrastructure. Read the whitepaper.
Every era of market infrastructure has a version of the same story. Liquidity gets trapped, the industry builds a fix, and the trap moves somewhere new. DTC immobilized paper certificates after the late-1960s paperwork crisis, CLS closed the FX timing gap after Herstatt, and tri-party repo freed collateral trapped in bilateral silos. Oliver Wyman puts the annual cost of trapped liquidity at $120 billion, and GFMA estimates $25.5 trillion in assets sitting idle as dead capital.
Public chains delivered the first proof that liquidity mobility can work. A user can route funds across rollups, swap stablecoins, and deploy into a yield strategy on a different chain inside a single transaction. The cost is fragmentation. Roughly $40 billion in liquidity sits dispersed across more than twenty L2s, and bridges have lost billions to exploits.
Private chains went the other way. The largest live institutional DLT processes around $385 billion in daily repo volume with strong privacy and sub-second finality, but the cash leg is captive to a single market. A treasurer moving the same dollar from a repo platform to an FX venue to a corporate payout needs three different cash instruments, three reconciliation paths, and three operating models. Mobility is the price.
Modern blockchains can deliver all three together by separating execution from settlement. Private execution environments keep transactions invisible to the public, while a shared mainnet keeps liquidity unified across venues. The trade-off between privacy and mobility was an artifact of older architectures, not a structural one.
Three properties to balance
Three properties matter for institutional cash infrastructure.
- Speed and reliability mean sub-second finality of transactions, dedicated blockspace to ensure that other activity on a blockchain cannot starve payments, and predictable fees that a treasury team can model. This is the easiest of the three to deliver and is no longer a differentiator.
- Privacy means payment amounts, counterparty identities, and balances stay invisible to the public. The issuer, the regulator, and the parties to a transaction each get exactly the visibility they need and no more.
- Liquidity mobility means the same cash can clear a repo trade, fund a cross-border payment, post margin at a derivatives venue, and settle a tokenized securities trade. None of those flows requires re-issuing the cash at each hop.
The first two are now available from multiple vendors. The third is what separates next-generation settlement infrastructure from the silos the industry has been building for the last decade.
Architecting for liquidity mobility
For most of the last decade, the trade-off looked binary. Private chains optimized for privacy and threw away mobility. Public chains optimized for mobility and threw away privacy. Builders accepted one as the cost of the other.
That trade-off was never structural. The architectural move that resolves it is the separation of execution from settlement. Private execution environments run as parallel chains where participants transact without public visibility. Funds remain in contracts on a common mainnet, assets stay interoperable across environments, and liquidity pools on the mainnet remain accessible. Privacy is handled at the execution layer. Liquidity is handled at the settlement layer. The two stop fighting each other.
FMI and bank strategists choosing settlement infrastructure today should be asking different questions than the industry has been asking. Not how fast, and not how private. The question is whether the cash leg can move across venues, asset classes, and use cases without being re-tokenized at every hop. Architectures that answer “yes” treat cash as first-class, and architectures that answer “no” are building a new silo at a new layer.
Our whitepaper, “Creating More Liquidity Mobility in Markets”, works through the historical pattern of trapped liquidity and the trade-offs in current institutional DLT designs. It also covers the architectural separation that lets cash stay mobile without sacrificing speed or privacy. Read the whitepaper.
