Settlement Is Now the Test, Not Tokenisation Isolated
The Bank of England and the Financial Conduct Authority have made the UK’s tokenisation agenda less about headline branding and more about infrastructure design. The shared package is no longer just about digital-asset innovation: it is now about whether wholesale markets can treat tokenised issuance, transfer and custody as production-grade payment and settlement flows.
In a joint statement on 18 May, the two regulators published a shared vision for tokenisation in UK wholesale markets and opened a second-phase consultation on market plumbing. The obvious story would be that tokenisation is about faster markets and cheaper settlement. The real story is that the public message stays the same while the operational test becomes tougher. The test is whether firms can show legal certainty, settlement finality, collateral treatment and cross-border payment utility before tokenisation moves from pilot to core finance infrastructure.
The UK already has a Digital Securities Sandbox and says firms are already using it to test live tokenised issuance and settlement. But the Bank of England has now connected that work to a wider blueprint. It is consulting on extending RTGS and CHAPS settlement windows so token-related transactions can be supported when market participants need near-continuous infrastructure rather than office-hour-only sequencing.
Why Settlement Hours Matter
The Bank says the next phase of CHAPS extension could include weekend capability, most likely a Sunday window, from 2029. The next stage is still future. In the same consultation, it also signalled a possible extension of daily windows later. In practical terms, tokenised assets and collateral movements need not force firms to compress their workflows into narrower windows, but the regulator framing puts pressure on firms that rely on old intraday assumptions.
A key reason is synchronisation: the Bank’s external-ledger synchronisation service is intended to coordinate the movement of central bank money in RTGS with movements of tokenised assets or funds on external systems. That coordination matters because token settlement only works if transfer, payment and control rights all move together, with atomicity where appropriate.
Why Atomic Settlement Is the Centrepiece
The consultation language is clear on the risk of half-measures. If one leg of a settlement chain moves and the other does not, firms inherit replacement risk, collateral ambiguity and legal disputes. Synchronisation is therefore more than a technical feature: it is a legal and supervisory hinge.
At a minimum, the model envisages lock-and-release mechanics, stronger chain-of-control and clear governance around third-party synchronisation operators. Firms can test this in controlled environments now; the challenge is whether the model remains safe at scale when operational stress rises.
The point is as old as settlement itself. A financial system can tolerate innovation in asset representation only if the chain remains stable when liquidity dries up, counterparts fail, and network paths are disrupted. A token on a ledger does not remove these stresses.
The Prudential and Client-Protective Context
The Prudential Regulation Authority has published a Dear CEO letter on tokenised assets, stablecoins and related exposures. The message is explicit: prudence still applies. Banks and firms offering tokenised products still need clear evidence around risk appetite, controls, custody, vendor oversight and liquidity resilience.
The FCA and PRA are also asking how client asset protections map to tokenised holding models. That question has been central in other jurisdictions too, but in the UK it now intersects with the practical settlement project. If central bank money moves via RTGS synchronisation while a token ledger records transfer rights, firms need to explain what claim a client has to the asset at each stage and what happens if an intermediary fails.
The practical message to market operators is therefore straightforward: the legal design has to be explicit before commercial scale arrives.
The Cost of Progress
This is not a free efficiency play. Near-24x7 settlement means banks and infrastructure providers have to rethink staffing, maintenance windows, incident response, liquidity planning and cross-border coordination. The consultation frames this as a sequencing challenge: can the market prioritise use cases where the resilience gains exceed operating costs?
The same framing applies to tokenised collateral. In stable funding markets, if collateral movement and token movement are not fully aligned, a single operational glitch can create systemic knock-on effects across custody, settlement and valuation chains.
What Makes 2026 Different
The UK’s direction on tokenisation remains constrained by governance first, innovation second. That might sound disappointing to firms looking for a headline that signals immediate deregulation. But it is consistent with the UK playbook in adjacent areas: introduce new market infrastructure only where firms can show strong controls and evidence, not where promoters can show only demand.
For London markets, this framing could be structural. If the UK can prove tokenisation works inside production settlement architecture, it strengthens its case as a model for regulated token infrastructure. If it overpromises and under-delivers on control mechanics, the innovation signal is likely to weaken quickly.
The immediate operational test sits on a short policy clock. Feedback is open on the joint statement, and RTGS/CHAPS consultation deadlines are in coming months. Firms that want tokenisation to become a mainstream wholesale layer will need to provide evidence of settlement readiness, not just adoption narrative.
