Bank of England Turns Tokenisation Into A Settlement-Hours Problem
The Bank of England and the Financial Conduct Authority have made the UK’s tokenisation agenda less about digital-asset branding and more about the operating hours, collateral rules and settlement plumbing that would let wholesale markets use the technology safely.
In a joint statement published on 18 May, the Bank and FCA set out a shared vision for tokenisation in UK wholesale markets and opened a call for industry views. The familiar headline is that tokenisation can make the issuance, trading and settlement of securities faster and more efficient. The more important signal is where the authorities have put the hard questions: prudential treatment, tokenised collateral, settlement instruments, client asset rules and the ability of the UK’s core payment rails to support a market that does not run on old office-hour assumptions.
That is a sharper test than another sandbox announcement. The UK already has the Digital Securities Sandbox. The Bank and FCA say 16 firms are working on live issuance and settlement of tokenised assets through it. What changed this week is that the authorities tied the sandbox work to a broader map of market infrastructure.
The Bank is consulting on extending RTGS and CHAPS settlement hours, with confirmed early-morning CHAPS opening from September 2027 and possible Sunday and bank-holiday settlement from 2029. It is also targeting a live synchronisation service in 2028, so movements of central bank money can be linked conditionally to movements of assets on external ledgers.
That combination matters. Tokenisation is only useful at scale if settlement risk, liquidity and legal responsibility are clear when a trade moves from a conventional ledger into a distributed one. A tokenised bond that cannot settle efficiently in central bank money is not a revolution in market plumbing. It is a new wrapper around old frictions.
The UK Is Starting With Infrastructure
The Bank’s RTGS consultation is the practical heart of the announcement. It says the next phase of CHAPS extension could add a weekend settlement day, most likely Sunday, and certain bank holidays, not before 2029. A later phase, not before 2031, could lengthen the settlement window on existing days. In the longer term, the Bank is asking whether the UK should move towards 22x7 or 23.5x7 settlement.
This is not a narrow payments upgrade. The Bank explicitly connects longer settlement hours to a “multi-money ecosystem” in which central bank money, commercial bank money, tokenised deposits and stablecoins can coexist across conventional and distributed-ledger infrastructure. In that world, central bank money remains the anchor, but it has to be available in a way that private-sector systems can actually use.
The consultation also names the cost of ambition. Near-24x7 settlement means more operational complexity for banks, building societies, payment firms and financial market infrastructures. Liquidity operations, staffing, maintenance windows, incident response and cross-border coordination all become harder. The Bank is therefore asking industry to rank use cases, costs and sequencing rather than simply endorse permanent availability as an obvious good.
For wholesale markets, that is the right frame. Faster settlement can reduce risk, but badly sequenced infrastructure change can move risk into operations. The UK’s bet is that tokenisation will be credible only if the central bank settlement layer evolves deliberately alongside it.
Synchronisation Is The Bridge
The Bank’s synchronisation work explains the route. Synchronisation is designed to orchestrate movements of central bank money in RTGS with the transfer of assets or funds on external ledgers. In practice, that means a two-stage earmark and release process: assets or funds are locked first, then released when the conditions for the transaction are met.
The point is atomic settlement. Either each side of the transaction moves, or none does. That is valuable in foreign exchange, repo, digital securities and other markets where timing gaps create settlement and price risk. It is especially relevant for tokenised assets because the asset ledger may not be the same system as the money ledger.
The Bank says synchronisation could provide a route for Digital Securities Sandbox firms to settle digital-security transactions in sterling central bank money. It is also preparing for third-party synchronisation operators that would coordinate transaction flows without themselves holding central bank money.
That is where policy meets market design. If synchronisation operators become part of the settlement chain, regulators will need clarity on governance, resilience, liability and data standards. The model could support innovation, but it also creates a new category of infrastructure dependency.
The Prudential Message Is Cautious
The Prudential Regulation Authority has moved in parallel. Its Dear CEO letter on tokenised assets, stablecoins and other cryptoasset exposures, also published on 18 May, is addressed to banks and designated investment firms. The FCA and Bank said the PRA letters reaffirm expectations on risk management and compliance while updating guidance for tokenised exposures and innovations in deposits, e-money and stablecoins.
That is a useful restraint on the growth narrative. The official message is not that tokenisation lowers risk by default. It is that firms can explore the technology where they can explain the prudential treatment, collateral mechanics, custody obligations and operational controls.
The FCA has also said it will consider how client asset rules may need to evolve in light of industry feedback. That is important because tokenised markets do not remove the core investor-protection question: who holds what for whom, under which legal claim, and what happens when an intermediary fails?
The feedback deadline for the joint tokenisation call is 3 July 2026. The RTGS and CHAPS consultation runs to 10 August 2026. Those dates put the City on a short policy clock. Firms that want tokenisation to move from controlled pilots to production need to provide evidence about what rules or infrastructure are blocking them, not just repeat that distributed ledgers are efficient.
The City Test
The UK’s approach is now visibly different from a pure crypto-market strategy. It is not trying to win by loosening the perimeter first. It is trying to make regulated market infrastructure flexible enough for tokenised instruments, while keeping central bank money, prudential supervision and client protection at the centre.
That will disappoint firms looking for a fast deregulatory signal. It should interest banks, asset managers, financial market infrastructures and fintechs that need a credible production path. The prize is not a tokenised proof of concept. The prize is a market where issuance, collateral, settlement and custody can work inside the regulated system without adding hidden fragility.
The practical test is whether the roadmap can keep pace with market demand. A synchronisation service targeted for 2028 and weekend settlement no earlier than 2029 are not immediate fixes. But wholesale finance is not a consumer app. The infrastructure has to be boring enough to trust before it can be fast enough to matter.
That is the quiet significance of this week’s package. Britain is turning tokenisation from a technology story into a settlement-hours, collateral and supervisory design problem. For the City, that is where the real competition will be decided.
